[00:43:14] <fauge> yea whats up
[00:43:50] <davebaol> did you managed ai jump?
[00:44:12] <fauge> i have an ai jump
[00:44:46] *** waldohatesyou has quit IRC
[00:44:46] <davebaol> I'm adding a jump behavior to gdx-ai
[00:45:24] <davebaol> well I think that I'll add 2 jump behaviors with different approaches
[00:46:00] <fauge> ok cool!
[00:46:11] <fauge> are you going to use jump pads?
[00:46:30] <davebaol> the 1st with takeoff and landing locations which should be very accurate
[00:46:46] <davebaol> but level designer have to add locations manually
[00:46:59] <davebaol> has*
[00:47:26] <davebaol> the 2nd will autodetect jump points with raycast
[00:47:56] *** dogiz has quit IRC
[00:48:09] <fauge> are you the author of gdx-ai?
[00:48:17] <davebaol> yeah
[00:48:33] <fauge> are you the only author working on it?
[00:48:53] <davebaol> mainly
[00:49:14] <davebaol> contributions are welcome though
[00:49:34] *** Arrkangel has joined #libgdx
[00:50:07] <fauge> well a way to pass in variables to the ai state machine
[00:50:10] *** waldohatesyou has joined #libgdx
[00:50:18] <fauge> i could just not know how to do it
[00:50:32] <davebaol> what do you mean?
[00:50:58] <davebaol> anyways with the 2nd approach level designers only have to fill holes with an invisible obstacle
[00:51:05] <davebaol> but it's less error prunr
[00:51:10] <davebaol> prune^
[00:51:31] <davebaol> it's good for wide areas
[00:52:16] <fauge> would it work with box2d?
[00:53:22] <fauge> or how about the person passes in an array of rectangles
[00:53:34] <fauge> as the invisible obstacles
[00:54:00] *** hydra___ has quit IRC
[00:54:02] <davebaol> yes it should but usually jump behavior is more meaningful in 3D
[00:54:12] *** hydra__ has joined #libgdx
[00:54:12] *** WhiteDraegon has joined #libgdx
[00:54:18] <davebaol> fauge: a box2d body
[00:54:25] *** Burnrate has joined #libgdx
[00:54:36] <davebaol> raycast will detect the hole
[00:54:51] <davebaol> then the agent will jump
[00:55:09] <fauge> yeah will you have an overidable jump method
[00:55:40] <davebaol> I think I'll use a callback
[00:56:03] <fauge> when will the update be dave
[00:56:41] <davebaol> in the next days hpefully
[00:56:52] <davebaol> don't know when it will be merged though

[00:59:56] <Tann_> What sort of system are you making?
[01:00:34] <fauge> an enemy ai
[01:00:43] <fauge> with guns and bullets and stuff
[01:00:49] <Tann_> Oh
[01:00:54] <fauge> enemy ai capable of attacking
[01:00:58] *** esvee has quit IRC
[01:01:04] <Tann_> Yeah that can get tricky
[01:01:09] <fauge> well all the math required to do with art i can do
[01:01:14] <Tann_> Give them random spread on their attacks : P
[01:01:17] <fauge> the angles and stuff is simple
[01:01:19] <Tann_> 2d or 3d?
[01:01:26] <davebaol> movement ai if I got it right
[01:01:26] <fauge> thats what i was thinking tann 2d
[01:01:32] <davebaol> and a bit of decision making
[01:01:44] <Tann_> Yeah, random angles makes everything look great
[01:01:51] <fauge> dave could you implement an a* algarithm
[01:01:59] <fauge> that takes a 2d array of doubles
[01:02:03] <fauge> or floats
[01:02:13] <Tomski> Itz ezpz

[01:51:39] <davebaol> yeah but you need them to calculate the exact direction and speed in order not to fail the jump

[02:33:14] <francisl> Hi, I coding my first game, a vertical scrolling shoot’em all a la 1942. I want to have a parallax with clouds. At this point the the land is a tiled tilesets repeated over and over by reseting the camera.
[02:33:23] <Gtoknu> bhldev__ I'm having a good time deving with Ashley, though I think it's better to not mix it with stage2D
[02:33:31] *** Fulcano has joined #libgdx
[02:33:34] <Gtoknu> But that's just my opinion
[02:33:50] <bhldev__> it looks good
[02:33:52] <bhldev__> nice and simple
[02:33:54] <francisl> What would be the best way for clouds? random actor with texture or another tilesets?
[02:35:02] <Gtoknu> Francisl both way would work
[02:35:51] <Gtoknu> But it will be somewhat harder to implement parallax on a tile set layer
[02:36:03] <Gtoknu> But easier on a single actor
[02:36:04] <matthewt> what is an entity system
[02:36:54] <francisl> ok, is it possible to have two camera? one on each tilesets running at different speed ?
[02:37:09] <francisl> or the camera is related to the viewport?
[02:37:32] <bhldev__> matthewt good question the wiki for the ashley docs isn't written yet

[02:54:01] <Gtoknu> How can I uncouple animation and controller movement?
[02:54:32] <Gtoknu> For example, the player should change to running animation when the player is holding the right arrow key
[02:55:47] <Gtoknu> Should animation system track movement component, should controller system update animation component? Or should I set up a whole new system for this?
[02:57:13] <fauge> if the players direction change
[02:57:17] <fauge> update the animation
[02:57:36] <fauge> your art should follow your theoretical objects

[08:18:30] <TEttinger> yes, android gradle 0.10 is outdated IIRC
[08:18:41] <TEttinger> I think they're up to 0.12 minimum
[08:19:37] <fainosag> i've put 0.12 in the build.gradle of the all projects, now i wait for it to load :D
[08:20:02] <fainosag> how to run the main from android studio ? xD
[08:20:10] <fainosag> from edit configuration right?

[08:22:15] <Tomski> Make a run configuration, or just right click the launcher and run
[08:23:13] <fainosag> i can run the project if i'm not conected to internet?
[08:23:20] <Tomski> If you have the dependencies, yes
[08:23:53] <fainosag> i get Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: Couldn't load file: badlogic.jpg
[08:24:02] <fainosag> i don't even see an assets folder inside desktop project..
[08:24:27] <Tomski> Because its in android by default
[08:24:47] <Tomski> So you need to change your run configuration to havea android/assets as the working directory
[08:25:09] <Tomski> Its the same as: https://github.com/libgdx/libgdx/wiki/Gradle-and-Intellij-IDEA#running-your-project

[08:56:27] <TEttinger> hissing_girl just aged
[08:58:15] <fainosag_> TEttinger i'm newb to gwt, do you anything that is important for me to know while developing for android desktop and html?
[08:58:16] <fainosag_> things not to do, so the html won't crash or something?
[08:58:16] <fainosag_> do you know anything*
[08:58:16] <fainosag_> cause i saw that is very unstable
[08:58:27] <TEttinger> I just do android and desktop
[08:59:27] <TEttinger> I use scala which doesn't currently do html
[08:59:28] <fainosag_> why use scala instead of java?
[09:00:05] <fainosag_> better performance, or you know the language better?
[09:00:11] <TEttinger> mainly it made porting my C# easier since Java 6 (android compatible) is missing a lot relative to Scala
[09:00:16] <TEttinger> and relative to C#
[09:01:21] <TEttinger> I used delegates and anonymous functions a lot in C#, also their collections have way more featues than the ones in Java 6
[09:03:06] <fainosag_> after i run my project html5
[09:03:06] <TEttinger> Scala neatly maps almost everything in C#'s nice LINQ extensions to some similar thing in Scala
[09:03:07] <fainosag_> can i do it without internet connectin?
[09:03:07] <fainosag_> connection*
[09:03:07] <TEttinger> maybe.  if it doesn't use any online stuff, localhost works without internet

[09:46:56] <InspiredNotion> i guess you could rearrange the image cut and paste the lines..:) cheating
[09:47:27] <InspiredNotion> doh system update brb

[09:48:24] <LiquidNitrogen> oh never mind, im not even copying them, just the reference XD
[09:48:49] <TEttinger> LiquidNitrogen, I'm pretty sure there's clone() for some things, I don't remember how it works in java
[09:49:19] <TEttinger> I believe it returns an Object unless overridden
[09:49:24] <LiquidNitrogen> yeah i had a go at that but it seemed wierd
[09:49:51] <LiquidNitrogen> it kinda makes more sence just to reset the position members rather than dump and create a new object
[09:50:27] <LiquidNitrogen> this probably fixes my problem of the game randomly spawning rafts all over the grass too :D

[10:18:00] <Ali_> I have implemented Admob interstitials in my app. When testing, I found that the ads are coming in portarit mode although my app is in landscape mode. Has anyone faced any similar issue before?
[10:20:01] <Ali_> I'm not using any other views apart from the libGDX view as I'm using only interstitial ads. If i turn on auto rotate screen, ads are properly displaying in landscape mod as expected.

[10:53:53] <tr7-fov> 3d
[10:58:31] <passer> Tomski yes you are right. it's because gradle starts on java from JAVA_HOME not in that java where gdx-setup.jar started. Thank you very much.

[11:02:44] <wulong710> hello. I download "libgdx-master". Run "ant -f  fetch.xml" successfully. Then i want import "libgdx-master" project into "intellij idea", but i only can't see "build.gradle" or "gradlew" .How can i import this project. Am i miss something?
[11:02:53] *** Hronom has joined #libgdx
[11:03:10] <noooone> do you want to setup your own project, or setup libgdx?
[11:03:40] <noooone> afaik libgdx itself is no gradle project
[11:04:04] <wulong710> <noooone>: I just want run libgdx demo.
[11:04:41] <noooone> if that's all what you want you can get a little bit outdated version of the tests here: http://pixelscientists.com/blog/

[11:08:18] <Fastinyoh> Is there any reason why the scene2d.uiTable class doesn't have any method to remove a specific Cell from a table? Removing the cells directly from the Table's cell array causes the "cellAboveIndex" Cell member variable to misbehave horribly.
[11:08:33] <Fastinyoh> scene2d.ui.Table*
[11:08:40] <wulong710> <noooone>: I create project in this code by intellij-idea. But only can see a module "libgdx-master", can't see "desktop and android" modules.Then can't run this demo .Don't know how to run this demo.
[11:09:32] *** nepjua has quit IRC
[11:09:36] <tr7-fov> noooone how do i calculate my environment lights in my fragment shader?
[11:09:52] <noooone> Fastinyoh: you cannot just remove cells
[11:09:52] *** nepjua has joined #libgdx
[11:09:52] <wulong710> <noooone>: I will try it. Thank you.
[11:10:15] <noooone> Fastinyoh: you would at least add a colspan somewhere else to keep the layout
[11:10:37] <noooone> Fastinyoh: you can however just remove the actor from the cell
[11:10:49] <noooone> otherwise you need to clear the table and re-create it

[12:08:23] <mobaxe> in new version of libgdx , instead float value, it wants Matrix3
[12:08:53] <Ashiren> you mean scl not mul?

[12:14:05] <Ashiren> why woud they replace mul with scale :d
[12:14:42] <mk1> because mul is usually multiplication of two vectors why scale is multiplication with a scalar value and thus the same as "scaling" the vector
[12:15:08] <Ashiren> math nerd
[12:15:14] <noooone> I'd not have changed that though... just because of naming...
[12:15:21] <noooone> Vector is a PRETTY basic class
[12:15:27] <mk1> uneducated piece of shit :-P
[12:16:41] *** poxip has quit IRC
[12:17:41] <prophile> there are 4 (5?) common definitions of multiplication for vectors
[12:17:45] <prophile> and mul is ambiguous
[12:18:24] *** poxip has joined #libgdx
[12:18:42] <prophile> no, 6 actually—vector-scalar multiplication, dot product, cross product, vector-matrix multiplication, outer product, component-wise product
[12:21:54] <mk1> vec-matrix, matrix-matrix, outer product, dot product are all the same
[12:22:33] <mk1> (in terms of calculation)

[12:31:09] <prophile> "the server"?
[12:31:27] <noooone> freenode
[12:31:30] *** nicklatech-slp has joined #libgdx
[12:31:32] <prophile> freenode is a network of servers
[12:31:42] <prophile> when a link drops, it gets split into two networks
[12:31:43] <noooone> okaaaay, server cluster then
[12:31:46] <prophile> that's why it's called a netsplit
[12:32:24] <noooone> I know, and that's why I said it's probably happening because any freenode server went offline or something
[12:33:47] <prophile> if they were changing networking gear this morning it's more likely to be a link dropping

I did some research on this and it seems like a common issue with the Admob. I ended up putting some fix in the AndroidLauncher as shown in the below link. Hope it helps someone facing the similar issue. Happy coding..

[15:26:17] <prophile> rhino being what?
[15:26:25] <prophile> the JS engine?
[15:26:43] <davebaol> I think so
[15:27:33] <bhldev__> yeah or any other way for dynamic script execution
[15:27:42] <bhldev__> even a limited language or subset or some limited commands would be useful
[15:28:09] <prophile> I've used Luaj with some success
[15:28:21] <prophile> which has the advantage of not being javascript
[15:28:46] <prophile> alternatively, depending on what you want to do, jruby may be good for you since you immediately get all of libgdx without writing bindings that way

[16:56:01] <c0ke> That's going to be android specific, you can achieve this by creating an interface in your core project that fire all of your notification stuff to it, get your android project to have an implementation of this interface that then does the necessary stuff, your other platforms can just have an empty implementation
[16:56:19] <c0ke> There's a page on platform specific implementations somewhere, lemme find it

[17:11:43] *** noone has quit IRC
[17:12:28] <Hovaku> InspiredNotion: so just the default viewport?
[17:13:12] <InspiredNotion> well, i set it to 800x480 vice versa..if thats what you mean?
[17:13:32] *** eReS has quit IRC
[17:13:51] <InspiredNotion> stage = new Stage(new StretchedViewport(width,height));
[17:14:23] *** waldohatesyou has quit IRC
[17:14:26] <InspiredNotion> i take it you have used the stage before?
[17:14:40] <c0ke> I've got some scene2d.ui woes at the moment. I want everything to lay itself out nicely without stretching, but I want the components themselves to scale
[17:15:29] *** poxip^ has quit IRC
[17:15:33] <c0ke> I've heard that higher resolution skins might be the answer
[17:15:45] <InspiredNotion> maybe create 2 stages, or 1 stage and one Camera
[17:16:40] <InspiredNotion> i'm not too hot on Stage stuff, just use it to get by with the basics..
[17:17:18] <Hovaku> InspiredNotion: if you use the stretch viewport wouldn't text look massive on tablets and tiny on small screens?
[17:17:27] <Hovaku> Surely you want a constant size?
[17:18:56] <InspiredNotion> well you can set it to how ever you need it to be.. I'm not too fussed currently, you can also do checks for screen density and apply the relevant textures and alike for different screens.. also the asset manager will store different stuff for trelevant screen sizes as such
[17:19:37] <InspiredNotion> so there are ways to do it.. im not too worried at this point as i am only creating simple games.. when i do a full blown one i will make sure i utilise all the cool features on offer
[17:20:07] <InspiredNotion> you don't have to use tretch though :)

[19:16:50] <davebaol> read the note please
[19:20:01] <davebaol> but that's just to apply linear acceleration
[19:20:10] <davebaol> how to apply angular acc?
[19:21:14] <noone> torque I think
[19:21:53] <noone> which note do you mean? the one about gravity?
[19:22:03] <davebaol> at the end of the question
[19:22:44] <davebaol> it says to use body.setGravity in place of applyCentralForce
[19:23:37] <noone> I don't see a reason for that, the only difference is that the gravity will be applied each frame, the force just once
[19:23:50] <noone> setting the gravity like that would also disable the global gravity
[19:24:01] <noone> (for that body)
[19:25:26] <davebaol> "as suggested by an admin at the Bullet physics forums" sounds like something not to ignore
[19:25:49] <noone> he says that the admin advised that because it is not framerate dependent
[19:26:01] <noone> but the physics step should anyway have a fixed timestep
[19:26:49] <davebaol> don't know, maybe you're right
[19:27:24] <davebaol> anyways if you use applyForce

[19:28:36] *** deBugger has quit IRC
[19:30:47] <noone> well, the acceleration can be configured
[19:31:03] <noone> bullet will take the mass into account when applying a force I assume
[19:31:07] *** titoasty has quit IRC
[19:31:28] <noone> otherwise, why would I need to tell bullet about the mass, if I have to calculate the correct force myself
[19:32:05] <davebaol> then it should be named applyAcceleration
[19:32:11] *** kamui is now known as kam_away
[19:32:32] <noone> hhmmm
[19:33:00] <davebaol> just guessing though
[19:35:19] <noone> it's suprising that one is just not able to find any answers on the net for the most simple bullet problems
[19:36:37] <davebaol> yep
[19:37:03] *** waldohatesyou has quit IRC
[19:38:34] <davebaol> what happens if call applyForce after changing the mass of body?
[19:38:41] *** Fitzy has quit IRC
[19:38:51] <davebaol> a simple test should answer the question
[19:39:18] *** ThePixelMonster has joined #libgdx
[19:41:35] <noone> I'll try it with different mass
[19:42:06] <Hovaku> is Screen's render function only called when it's set in as a screen in Game?
[19:42:16] <Hovaku> set as*
[19:43:08] <noone> davebaol: with 0.5 mass it moves normally, setting the mass to 50.5 it doesn't move anymore at all
[19:43:12] *** pmartino has joined #libgdx
[19:43:55] <davebaol> then looks like applyForce applys acceleration
[19:44:06] <davebaol> with 2?
[19:45:10] <noone> with 2 it moves, but more "slow"
[19:45:17] <davebaol> ok then
[19:45:56] <noone> you are right, it should be named applyAcceleration
[19:46:22] <davebaol> yeah it's misleading
[19:46:45] <noone> but it doesn't really matter much... the mass is usually constant
[19:46:48] *** Xoppa has joined #libgdx
[19:46:48] *** ChanServ sets mode: +o Xoppa
[19:46:53] <noone> and you need to tweak the parameters anyway
[19:47:17] <davebaol> yes but different bodyes might have different mass
[19:47:38] <davebaol> and if you apply a behavior with the same paramenter....
[19:47:50] <davebaol> parameters^
[19:48:32] <noone> then they would behave different, but isn't that what you would expect?
[19:48:43] <davebaol> yes it is
[19:49:08] <davebaol> I just meant that the steering system completely ignores the mass
[19:49:27] <davebaol> that's why it produces acceleration
[19:49:36] <davebaol> and not a force
[19:49:55] <noone> but in this case what we do is correct... using applyForce (which is actually applyAcceleration)
[19:50:17] <davebaol> yes, now we know it conceptually correct
[19:50:40] <davebaol> just conceptually though :)

[19:58:40] <noone> I just never ever finish them
[19:59:14] <BlueProtoman> On a more serious note, idea for the steering behaviors--a NullBehavior that applies no acceleration.  It's for entities that shouldn't move (at least not by steering behaviors, e.g. the player), but should still be considered for GroupBehaviors.
[19:59:38] *** abs25 has left #libgdx
[19:59:43] <noone> Xoppa: I did that after I noticed the crashes, but it then my collision handling does not really work at all anymore...

[20:00:41] <noone> I have a player and a pickup... I want to remove the pickup on collision

[20:01:04] <Xoppa> noone, try to do it in the InternalTickCallback https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests/src/com/badlogic/gdx/tests/bullet/InternalTickTest.java
[20:01:16] *** Gloria_Watsica has joined #libgdx
[20:01:43] <noone> ... then I get a second callback and because I've already deleted my entity, I get NPEs and such
[20:02:31] <Xoppa> ... NPE should be solvable in code (if (x != null) ...)
[20:02:51] <noone> hmmm, I still didn't really understand what internaltickcallback does... will try to find something online
[20:03:05] *** Gloria_Watsica has quit IRC
[20:03:11] <noone> Xoppa: yeah, but I don't like nullchecks much
[20:03:22] <noone> I prefer to solve the origin of the problem :D
[20:04:15] *** Fastinyoh has quit IRC
[20:04:32] <Xoppa> internal tick is get called for every physics iteration (fixed time steps). so if e.g. 0.5 second is passed and you've set the step time to 0.1 second then it will be called 5 times (in between each step)
[20:06:00] *** Hatura has joined #libgdx
[20:06:44] <noone> ah, got it... does that mean that I should actually only get 1 callback per physics step with the other listeners?

[20:19:34] <prophile> I highly recommend turning on display of tab characters in your editor
[20:20:47] <davebaol> noone: looks like truncating max lin/ang velocity after applying the force doesn't work very well
[20:21:41] <Flaiker> yeah its tabs vs spaces, http://i.imgur.com/JHVMXYM.png
[20:21:43] <noone> that might be... the force is actually applied after the truncation in the physics step
[20:21:54] <davebaol> yep
[20:22:10] <davebaol> you can easily see it with ang velocity
[20:22:31] <davebaol> in update I forced steering.angular = 1000
[20:22:46] <davebaol> also I added truncation code
[20:22:52] <davebaol> it still rotate
[20:23:04] <davebaol> I mean truncating to 0
[20:23:09] <Xoppa> the sense of internaltickcallbackTest is to test the InternalTickCallback
[20:23:42] <Flaiker> so whats the norm, tabs or spaces? intellij seems to be spaces, setup ui tabs and github doesnt like both
[20:23:50] <noone> Xoppa: okay, but it doesn't really do anything useful, right?
[20:24:04] *** WhiteDraegon has joined #libgdx
[20:24:25] <davebaol> Xoppa is there a way in bullet to set max linear and angula velocity?
[20:24:39] <Xoppa> noone, if you don't think that testing InternalTickCallback is useful, then indeed it does nothing useful
[20:25:13] <Xoppa> davebaol, iirc there is, check the manual, it should be in there
[20:25:25] <noone> Xoppa: well, at first I thought you need the internal callback to let the bodies jump like that or something, I dunno
[20:26:42] <Xoppa> the test shows applying forces, which is something you would want to do every tck
[20:27:59] <davebaol> Xoppa: are you talking to me?

[20:29:18] <noone> that's how I did it :/
[20:31:46] <noone> maybe we would need to do this as well in the internal tick callback...
[20:34:23] <davebaol> might work
[20:36:03] <davebaol> this means that each body needs its own callback right?
[20:38:52] <noone> that's probably overkill
[20:39:14] <noone> the callback should have a list of all bodies and perform the speedcapping
[20:40:52] *** Gtoknu has joined #libgdx
[20:41:22] <noone> damnit... removing the bodies in the internal tick callback also results in a crash
[20:41:44] <noone> it's so weird that it works with some bodies and with others it doesn'T
[20:42:27] <davebaol> noone: did you try with preTick=true ?
[20:42:54] <noone> yes
[20:43:36] <davebaol> noone: BTW having a list of all bodies sonds like an entity system, not a framwork
[20:44:04] <noone> yeah, but it's JNI

[20:44:41] *** Hatura has quit IRC

[20:57:06] <nepjua> never mind i read it :)
[20:57:53] <doodli> Thanks @Xoppa, i missed the distanceLinePoint() method!   That would get the triangle bisector distance for me!  Another (math) question: How to I get the normal vector of the triangle? Is the normal vector = the first vertex? It looks wrong to me but i cannot find out how to get it otherwise
[20:59:42] <Xoppa> doodli, lmgtfy http://math.stackexchange.com/questions/305642/how-to-find-surface-normal-of-a-triangle
[21:02:34] <Xoppa> doodli, in code it would be something like: Vector3 normal = new Vector3(x2-x1, y2-y1, z2-z1).crs(x3-x1, y3-y1, z3-z1);
[21:03:21] <Xoppa> you could check the dot product to get the "correct" normal (because this will produce either forward or backward vector)
[21:03:51] <noone> Xoppa: I have no idea what happened now, but now it suddenly works and I can remove any body anytime without a crash....

[21:35:27] <diphtherial> nepjua: i'm confused by the number of smileys you stuck in those sentences
[21:35:48] <diphtherial> if you mean a literal third dimension, you'd be far better off using bullet imho
[21:36:13] <diphtherial> if you mean faking a third dimension by allowing things to overlap and then suddenly not, forcing them out of the way as though it were just inserted from "above", sure, that's doable with box2d
[21:36:17] <nepjua> diphtherial: i actually work on 2d, it's basically like a table hockey
[21:36:20] <diphtherial> *suddenly making them not
[21:36:35] <diphtherial> i see; what's the problem, then?
[21:36:53] <nepjua> diphtherial: i need friction on the board so that my objects gets slower
[21:37:02] *** nicklatech-slp has quit IRC
[21:37:12] <diphtherial> aha, yes, this is a common issue with box2d; you can apply linear damping to fake friction with a surface
[21:37:16] <nepjua> diphtherial: when i put them on same third dimension the board forces the objects out :)
[21:37:35] *** nicklatech-slp has joined #libgdx
[21:37:42] <nepjua> diphtherial: is damping similar to friction ?
[21:38:06] <diphtherial> it's not exactly the same, but it's close enough; it basically multiplies the velocity by the linear damping coefficient each frame
[21:38:22] *** pmartino has quit IRC
[21:38:25] <nepjua> diphtherial: that's perfect, just what i needed thanks
[21:39:03] <diphtherial> it's a little tricky to tweak it until it's just right, but it's possible :) no problem
[21:40:42] <nepjua> diphtherial: i just tested it, it's definitely usable :)
[21:41:09] *** waldohatesyou has joined #libgdx
[21:41:27] *** vestu has quit IRC
[21:44:18] <diphtherial> fwiw, friction in real life works somewhat the same, except the frictional force is proportional to the normal force (the force that objects exert on the floor due to gravity)
[21:44:39] <diphtherial> there's a frictional coefficient that varies for different surfaces that serves the same purpose the linear damping coefficient you're using
[21:45:25] <diphtherial> the difference is that the linear damping coefficient is being applied to the velocity, whereas the frictional force is a force and thus contributes to the acceleration (where accel = the sum of the forces divided by the mass of the object)
[21:45:29] <diphtherial> anyway
[21:48:56] <prophile> linear damping violates the law of conservation of energy
[21:49:06] *** stefzekiller has joined #libgdx
[21:51:17] <diphtherial> indeed
[21:51:57] <diphtherial> but hey, if you want to talk about resemblance to reality, there are equally glaring problems with box2d...
[21:52:14] <prophile> like its being 2D
[21:52:19] <diphtherial> heh :)
[21:52:30] <diphtherial> game physics just have to be believable; they don't have to be accurate, imvho
[21:52:52] <prophile> ^
[21:52:54] <prophile> truth
[21:54:39] <deniska> like minecraft where you can jump one meter high and gravity acceleration is about 20 m/s²
[21:55:13] <prophile> I think the possibility of floating blocks is a rather bigger physics issue with minecraft
[21:55:15] <prophile> ;)
[21:55:18] <prophile> or infinite water
[21:55:44] <prophile> or carrying 2304 cubic metres of gold in a backpack
[21:56:52] <prophile> (more than a typical cargo ship in weight)
[21:58:14] <deniska> minecraft water physics was different very early in the game

[22:45:32] <Xoppa> tye887, your question is very broad, try explaining the actual problem, what problem are you trying to solve and in which context, show some example code (pastebin), what have you tried to solve the problem and what is wrong with it etc.

[22:53:18] <tye887> xoppa here are my shaders: http://pastebin.com/P9qUjgwR my fragment shader currently calculates light colors and positions to the equation, but i have no knowledge to insert light data. i use shader.setuniform... to set uniforms
[22:53:50] *** pmartino has joined #libgdx
[22:56:18] <noone> Xoppa: god damnit I don't understand bullet physics... this stupid callback is not called every time... like in every 3rd time I start the game it will happen. Plus this callback is called FOREVER after I've removed the body... and it checks the collision with my Player, which was never even close to any of those bodies that I've removed
[22:57:31] <Xoppa> tye887, shaders are typically used to solve problems, try explaining the actual problem and the context
[22:57:40] *** nicklatech-slp is now known as teh_nick_ao
[22:57:55] <Xoppa> noone, its magic
[22:58:03] <tye887> how does my fragment shader get light data for shading?
[22:58:32] <tye887> i just used environment when using default shader
[22:58:58] <Xoppa> your fragment shader fetches the data at the location specified for the uniform
[22:59:14] <Xoppa> or varying, whichever you've used
[22:59:58] <Xoppa> tye887, ah, that helps a bit, so you're using 3d and modelbatch and alike?

[23:00:56] <gemurdock> Why doesn't the Game.render() pass float delta?
[23:01:15] <Xoppa> noone, does it also fail when you delete them while not in the simulation step at all?
[23:01:45] <tye887> like this: modelbatch.render(modelinstance, my custom shader); i used to do environment = new Environment(); and environment.add(new PointLight().set(1f, 1f, 1f, -2, -4f, -1f, 1));
[23:02:01] *** Ricorei has joined #libgdx
[23:02:17] <Xoppa> gemurdock, because someone (probably mario) implemented it that way. Why would you expect it pass float delta?
[23:02:25] <BlueProtoman> gemurdock: I think Game grabs the delta time internally and passes that off to the current Screen
[23:02:53] <tye887> but how do my shader get lights into equation? only ambient light works and im setting it with shader.setuniformf()
[23:02:59] <gemurdock> if (screen != null) screen.render(Gdx.graphics.getDeltaTime());
[23:03:14] <gemurdock> that is what it does in game
[23:03:21] <gemurdock> Xoppa: yes I would expect it to pass
[23:03:35] <gemurdock> BlueProtoman: your right
[23:03:35] <Xoppa> tye887, check these 3d api tutorials http://blog.xoppa.com/ e.g. here is explained how to create a shader and here is explained how to pass custom data to your shader http://blog.xoppa.com/using-materials-with-libgdx/
[23:03:46] <Xoppa> gemurdock, why?
[23:04:12] <gemurdock> Xoppa: I hate to say this, but why not? Less for me to code... by one line
[23:04:12] <gemurdock> :)

[23:08:12] <doodli> Hi xoppa me again, i dont understand your formula above "Vector3 normal = new Vector3(x2-x1, y2-y1, z2-z1).crs(x3-x1, y3-y1, z3-z1);".  I'm trying to find the surface normal of a 2d triangle, so the z-coordinates is all zeros? I tried to use Vector2.crs but it gives float instead of a Vector @@, sry bad maths i dont know why cross product of vector
[23:08:12] <doodli> 2 is a value but crs for a vector3 is vector3  omg magic :((
[23:08:40] <gemurdock> Xoppa: Now I have to do this: render(Gdx.graphics.getDeltaTime()); so that I can pass it or I have to do: float delta = Gdx.graphics.getDeltaTime();
[23:09:36] *** pwnz_ has quit IRC
[23:09:46] <Xoppa> doodli, the normal of a 2d triangle (on the XY plane) is always pointing towards Z
[23:10:22] *** pwnz has joined #libgdx
[23:10:35] <tye887> xoppa i know how to set diffusecolor to shader, but how to program lights?
[23:10:43] *** ruben01 has left #libgdx
[23:10:46] <Xoppa> gemurdock, i see. consider sending a pull request for it
[23:10:46] <tye887> nothing about lighting in those links
[23:12:19] <doodli> hmm, i think i must have confuse the mathematical terms... What I'm trying to find is the unit vector of the edge of a 2d triangle to the surface it is facing: http://dev.yuanworks.com/wp-content/uploads/2013/03/Tile.png
[23:12:30] <gemurdock> Xoppa: ok, if I get the time I will
[23:12:41] <Xoppa> tye887, your question was how to get light data to the shader, getting data to the shader is the same for every kind of data. Like I said, try to explain the actual problem you're trying to solve...
[23:14:50] <tye887> okay. then how do i program lights? ive only used the environment.set way
[23:15:11] <tye887> (and have no idea how to send that data to my shader)
[23:16:04] <noone> why is the Environment.set way not enough?
[23:16:06] <Xoppa> doodli, i think you could use vector projection for it, but i'm sure that there's a better method that google will come up with
[23:16:38] <Xoppa> tye887, what is the actual problem? ...
[23:17:39] <tye887> i have no idea how to program lights. with defaultshader it used to be with environment, but now with custom shader i cant get lighting
[23:18:04] <tye887> i know what to do when i have the light data, but i have none
[23:19:11] <Xoppa> tye887, the Renderable that the shader receives contains both the Material and Environment, so you have the data.
[23:19:34] <Xoppa> you still haven't explained the actual problem though
[23:20:06] *** monkeyhybrid has joined #libgdx
[23:21:49] <tye887> i dont know how explain. i just cant get lighting to work
[23:21:51] *** Hronom has joined #libgdx
[23:24:22] <Xoppa> if you can't explain perhaps showing a screenshot will help explaining what you want to achieve
[23:24:26] <doodli> I tried to google but i really dont know what is the correct words for what i want to find: "triangle origin unit vector that points perpendicularly at the surface". http://dev.yuanworks.com/wp-content/uploads/2013/03/Tile.png
[23:25:43] <Xoppa> doodli, i think it is called median (don't use the word "unit" though)
[23:25:46] *** gemurdock has quit IRC
[23:27:12] *** waldohatesyou has joined #libgdx
[23:27:28] <doodli> Is my assumption correct?  The  n vector is the normalized vector of the d (the x and y component to reach from the origin).
[23:28:56] <davebaol> never seen mobidevelop so silent :)
[23:29:04] <tye887> xoppa i just set my pointlight color and position from renderable.environment but still no light
[23:29:21] <Xoppa> doodli, a normalized (unit) vector means that the length (sqrt(x*x + y*y)) is exactly one
[23:29:39] <Xoppa> so dividing a vector by its length will produce a normalize vector
[23:30:03] <Xoppa> so it could be that your assumption is correct, there's not enough information to verify
[23:30:49] <noone> Xoppa: when I do it after the physics step, it also causes this weird callback to keep happening (SOMETIMES). when I do it in the internal tick callback it will (SOMETIMES) cause bullet to crash when performing the physics step
[23:30:53] <doodli> Ok, i will code away, if i can achieve what i want then it means im correct :)   too much sqrt though!
[23:30:57] <Xoppa> tye887, okay
[23:32:11] <tye887> what am i doing wrong?
[23:33:02] <Xoppa> noone, so removing bodies outside the simulation step should does never cause a crash? but is does cause a weird callback happening. Can you exaplin again what you mean by weird callback?
[23:33:16] <Xoppa> tye887, you haven't provided enough information for us to help you
[23:33:25] *** [[derek]] has quit IRC
[23:35:10] <noone> Xoppa: thanks for your consistent support here on this problem! by weird callback I mean that my CollisionDispatcher is constantly called (needsCollision), after I have removed the body
[23:35:39] <noone> it asks for one specific body to collide with my player, even though they have never been colliding before
[23:36:07] <noone> and it does not always happen...
[23:36:15] <noone> that's why I consider it "weird" :/
[23:36:47] <Xoppa> and you're sure that you correctly removed the body from the world i'd assume?
[23:36:50] *** ksclarke has quit IRC
[23:37:34] <noone> how can I prove it?
[23:37:57] *** teh_nick_ao has joined #libgdx
[23:38:22] <Xoppa> i guess you could iterate over all bodies to ensure none of them have the CPtr as the body you've removed
[23:39:54] *** tye887 has quit IRC
[23:40:52] *** nepjua has joined #libgdx
[23:42:04] <Xoppa> noone, you do mean: bool	btCollisionDispatcher::needsCollision(const btCollisionObject* body0,const btCollisionObject* body1)
[23:43:39] <Xoppa> i gues that is only being called here: https://github.com/bulletphysics/bullet3/blob/master/src/BulletCollision/CollisionDispatch/btCollisionDispatcher.cpp#L259
[23:44:18] <Xoppa> and some algorithms https://github.com/bulletphysics/bullet3/search?utf8=%E2%9C%93&q=needsCollision

[23:45:47] <doodli> *noone deserves the higher Gods*
[23:46:00] *** Arrkangel_ has joined #libgdx
[23:47:10] <Xoppa> doodli, if you project (mutliple with the dot product) the v2-v1 vector onto the normalized v3-v1 vector, and then substract v2-v1 from it, and then normalize the result you will get the result that you want
[23:48:22] *** Keniyal has joined #libgdx
[23:48:36] *** harha_ has quit IRC
[23:49:10] <Xoppa> something like Vector3 v = new Vector3(v3).substract(v1).nor(); v.scl(v.dot(new Vector3(v2).sub(v1)); v.sub(new Vector3(v2).sub(v1)).nor(); // untested code
[23:49:22] <doodli> Do you mean that i get the same thing with:  (((v2-v1).dot((v3-v1).nor())).sub(v2-v1)).nor()?
