November 15, 2015 [00:00:58] <Xoppa> ASneakyFox, https://github.com/libgdx/libgdx/blob/0.9.8/tests/gdx-tests/src/com/badlogic/gdx/tests/PickingTest.java google code is very very old and not supported anymore. Also, it probably is not very usable anymore. What is it that you are actually looking for?[00:05:42] <ASneakyFox> Xoppa, I'm trying to do a mesh accurate ray cast, so i can find the elevation at the characters point on the terrain (so they walk on the terrain). There doesnt seem to be any examples anywhere of anyone doing that[00:05:46] <intrigus> https://github.com/libgdx/libgdx/blob/dcc1ee7feb0a526dbb723fdbc1e6738c48d1d3d7/tests/gdx-tests/src/com/badlogic/gdx/tests/PickingTest.java[00:05:48] <ASneakyFox> so i was kind of reaching[00:07:04] <intrigus> @Xoppa why is http://www.badlogicgames.com/forum/viewtopic.php?f=17&t=21017 not in the core?[00:07:13] <Xoppa> ASneakyFox, that should kinda be an indication that you might want to reconsider your approach[00:07:45] <Xoppa> intrigus, because no one contributed it[00:10:53] <ASneakyFox> how else can you get a point on a mesh besides raycasting?[00:11:12] <Xoppa> ow that normalizing code doesnt look correct btw intrigus[00:11:35] <intrigus> Not my code Xoppa ^^[00:11:35] <Xoppa> ASneakyFox, the question is why you want to get a point on a mesh in the first place[00:12:50] <ASneakyFox> so I can get the elevation at any point on the map (so the characters know where to stand, also affects gameplay mechanics etc)[00:12:55] <Xoppa> you made me look at it intrigus :D[00:13:17] <Xoppa> ASneakyFox, height map?[00:13:37] <ASneakyFox> yes (actually im using your heightmap code from the tests directory)[00:13:43] <Adnn> If I do sprite = atlas.createSprite("filename");, is there a combination of methods that will let me get the filename back from the sprite ? Without implementing my own.[00:13:45] * intrigus hides[00:14:05] <Xoppa> ASneakyFox, then use the x,z value to get the y value, no need to cast a ray for that[00:14:42] <Xoppa> Adnn, no[00:15:12] <Adnn> Alright[00:15:14] <Xoppa> although you might not mean filename, but the name of the region, in which case you could iterate over all region names of the atlas[00:16:31] <ASneakyFox> Xoppa, your heightfield uses integers for coordinates though. I thoguht about doing it that way but I would have to interpolate between the nearest coordinates to get the actual height though. Thats my backup plan if i cant figure out raycasting though[00:16:54] <ASneakyFox> raycasting also has the advantage of being universal to work with buildings and stuff if i add those in[00:18:27] <Adnn> That wouldn't solve the original problem Xoppa, but I'll just go the easy way and supply the sprites with IDs. I need that to tell which sprites to load amongst the clients.[00:20:15] <Xoppa> its been a while since i made that, but it probably does not have exactly the method that you need ASneakyFox, interpolating between the points is a way better idea then raycasting against a mesh. Keep this rule in mind: (graphical) games is all about taking shortcuts to make it look real, universal (real) methods are almost never the solution.[00:22:27] <Xoppa> ow Adnn you can cast it to AtlasRegion (if possible) and then call getAtlasRegion().name[00:22:42] <Xoppa> *AtlasRegion = AtlasSprite[00:23:05] <ASneakyFox> thanks, I think i'm close to figuring this out. Your heightmap example is pretty awesome btw.[00:25:32] <Xoppa> yw[00:28:37] *** TEttinger has quit IRC[00:31:55] *** point has joined #libgdx[00:38:11] *** jwinterm_ has joined #libgdx[00:39:58] *** abs25 has quit IRC[00:42:04] *** jwinterm has quit IRC[00:46:13] *** Kotcrab has quit IRC[00:50:38] *** ShivanHunter has joined #libgdx[00:53:47] <duli> hi[00:53:57] <duli> could anyone please tell me how can I profile a game[00:54:09] <duli> to look for memory leaks etc.[00:54:44] <duli> I've noticed that my fps drops gradually and to 40 and then it suddenly recovers which is weird[00:57:58] *** hextileX has joined #libgdx[00:58:18] <ASneakyFox> duli, you want to use VisualVM, it comes with the java jdk, theres plugins for it for eclipse and intellij idea[00:58:41] <point> if you are using AS, maybe you can use the device monitor tool.[00:59:15] <ASneakyFox> yeh android i know how its own special tool just for android, never really used it yet though, not sure about ios[01:00:06] *** MrH4mst3r has joined #libgdx[01:02:49] *** Antekaa has joined #libgdx[01:03:34] *** hextileX has quit IRC[01:04:10] *** MrHamst3r has quit IRC[01:04:22] <Xoppa> why care about fps drops to 40?[01:05:14] *** Anteka has quit IRC[01:05:43] <point> Hi, is there a difference between world space coordinates and stage coordinates?[01:06:05] <Xoppa> not if it is using the same camera[01:06:22] <Xoppa> which you probably dont want, so, yes[01:08:41] <point> are they in a 2d world the same?[01:09:18] <Xoppa> the world coordinates are the same in the same world, yes, regardless 1D or 2D[01:09:39] <point> ok, ty.[01:10:19] *** Epoch`_ has joined #libgdx[01:11:06] <point> can I ask you some basic understanding questions?[01:11:14] *** Delmadan has joined #libgdx[01:11:25] <Xoppa> ¨If you have a question, just ask¨[01:13:18] *** z11 has quit IRC[01:13:36] <point> one assigns a viewport to a cam and a stage. a stage can be smaller or bigger than what a cam can show on a screen. is it right?[01:14:05] *** z11 has joined #libgdx[01:14:20] *** Mezzenstein has quit IRC[01:14:44] *** MrH4mst3r has quit IRC[01:15:08] *** guardianL__ has quit IRC[01:15:23] *** Delmadan has quit IRC[01:15:45] <Xoppa> the size of the stage is defined as the size of the viewport which is (by definition) exactly the size the cam can see (and project onto the screen)[01:16:34] <point> ok, this is what I understood from the docs etc.[01:16:40] <Xoppa> https://github.com/libgdx/libgdx/blob/master/gdx/src/com/badlogic/gdx/scenes/scene2d/Stage.java#L675-L682[01:17:09] <Xoppa> that doesnt mean that your stage can contain actors which arent visible to the cam[01:17:14] <Xoppa> *cannot[01:17:27] <Xoppa> euhm, you get it[01:17:48] <point> yes, I get it :)[01:18:31] <point> the viewports can have different sizes too. but when do you assign a bigger/smaller viewport to a scene?[01:18:38] <Xoppa> having to ask this question might be an indication that you are using a stage for game play which is usually not a good idea[01:19:36] <point> hmmm, you are right[01:20:05] <point> so I need a better tutorial[01:20:06] *** Biliogadafr has quit IRC[01:20:27] <Xoppa> here you go: https://github.com/libgdx/libgdx/wiki/A-simple-game[01:26:59] <z11> That link was not intended for me but I am glad you typed it in.[01:26:59] <point> thank you!

well, since it's not a 3D game)[11:24:29] <vurpo> Now I tried adding slowdown when driving on grass, so I made the grass consist of a bunch of sensor fixtures that are polygons[11:25:01] <vurpo> since it doesn't support non-convex shaped, it's divided into many polygons[11:26:05] <vurpo> So I made it very simple, i.e. raising the linear damping of the kart in the beginContact if it contacts with the sensor, then lowering it in the endContact[11:27:10] *** Larry1123 has quit IRC[11:27:18] <vurpo> While driving on grass, though, it calls endContact and beginContact a lot (I assume on the edges

[twisti]: dependency injection is the way to go?[13:24:04] *** gentlemandroid has joined #libgdx[13:24:11] <[twisti]> yes[13:24:36] <badlogic> DI won't work with GWT if you want to target

you don't have to send anything, it gets injected[13:26:33] <badlogic> you can get pretty much all of DIs benefits minus all its downsides with a pluggable singleton :p[13:26:47] <[twisti]> badlogic:

<badlogic> nobody does :)[13:34:13] <Lecherito> xDD[13:34:14] <badlogic> absof25: short version: you annotate fields in your classes, e.g. @Inject MyThingy thingy[13:34:17] <Lecherito> I know some DI[13:34:28] <Lecherito> But I could not make anything work with dagger2[13:34:48] <badlogic> abs25: then you tell the DI how to create MyThingy, depends on framework, could be a method in a class annotated with @Provides(MyThingy.class)[13:35:08] <badlogic> abs25: when the app starts up, you tell the DI "Ok dude, please create all my thingies and inject them everywhere i annotated stuff"[13:35:19] <badlogic> and this is usually were things break down :D[13:35:25] <badlogic> because it's damn hard to track dependency chains[13:35:32] <badlogic> or figure out what's going on[13:35:46] <badlogic> you hand over a huge amount of stuff to the DI framework, and i don't like that bit of DI very much[13:37:27] <Lecherito> How would you approach then if starting with DI?[13:37:53] *** ficolas has joined #libgdx[13:38:02] <Lecherito> badlogic: I still find it handy[13:38:04] <badlogic> not using it in a game, but something else. e.g. simple backend, simple Android app[13:38:05] <Lecherito> without abusing it[13:38:11] <badlogic> oh, not saying it's useless[13:38:37] <badlogic> but most folks using DI are at the "i'm gonna architect the shit out of this todo

I have a stage with a group of actors which create a checkerboard. The size of the board is bigger than the screen, that's why you can move the camera. The problem is, only the actors, visible when the app is started, receive touch events.[18:58:33] *** Tomski has quit IRC[19:09:03] *** c0ke has left #libgdx[19:14:06] *** Ange_blond_ has quit IRC[19:16:39] *** domokato has joined #libgdx[19:16:53] <noone__> point: do you use two different cameras?[19:17:06] <noone__> sounds like you use one to draw and another to process touch events[19:17:26] <noone__> just show some code :D[19:17:41] <point> Hi noone__[19:18:55] <point> I'm using one cam and a stage with a viewport.[19:19:55] <cackling_ladies> noone__, what happened to the zeroes?[19:19:56] <point> I've read about the unproject methode which helps me to get the right coordinates after the cam has been moved.[19:20:15] <cackling_ladies> it's like someone punched out your extra eyes![19:20:25] <noone__> use the viewport to unproject[19:20:37] *** noone__ is now known as n0_0ne[19:21:00] <point> really? -.-[19:21:14] <point> ok, I will give it a try[19:21:28] <point> brb[19:21:47] *** domokato has quit IRC[19:31:59] *** mobidevelop has quit IRC[19:44:44] *** Xoppa has joined #libgdx[19:44:44] *** ChanServ sets mode: +o Xoppa[19:47:36] *** ASneakyFox has joined #libgdx[19:58:59] *** LostWarrior has joined #libgdx[20:07:10] *** darkamikaze has joined #libgdx[20:13:01] *** abs25 has joined #libgdx[20:14:01] *** ftgf2 has quit IRC[20:15:44] *** jivemeat has joined #libgdx[20:23:38] *** Radther_ has joined #libgdx[20:25:15] *** Radther has quit IRC[20:26:48] *** Kuvis has quit IRC[20:40:01] <point> Hey n0_0ne, sorry, but I couldn't give it a try immediately.

This is, because I use a custom gestureListener class.

I've just finished getting my map transitioning code working properly so you can go up and down stairs, walk between maps and such… the only thing is… I've had this stupid idea to show a nice zelda style room transition when you switch maps and I'm not sure the best way to approach it. Everything is written to handle rendering a single map at a time and all of it's entities so i can't just tell it to render[23:03:26] <c0ke> Does that sound feasible? :P[23:06:34] <codi^r> you could render the last frame of the old map to a texture, then use this texture for some overlay effect while starting to render the new map[23:09:18] *** scellow has joined #libgdx[23:11:24] *** Mezzenstein has quit IRC[23:12:00] *** Adnn has joined #libgdx[23:13:17] *** Ange_blond_ has joined #libgdx[23:14:28] <c0ke> I've not done anything like this, does that involve using a framebuffer thingy?[23:14:40] <Adnn> I'm getting an exception saying that I'm adding an already registered entity, but just four lines before I'm clearly making a new one .-. http://pastebin.com/CNKGNTNH (line 116). Any wild guesses ?[23:15:19] <c0ke> You are adding the entity to the engine inside your for loop ;)[23:15:28] <c0ke> Meaning if there's more than one component you are adding it more than once[23:15:37] <Adnn> True ! Haha, f*ck me[23:16:41] <codi^r> c0ke: yes, render to a framebuffer, then use this fb as texture later on[23:17:13] <codi^r> what kind of transition effect is that actually?[23:17:17] <c0ke> mmkay cheers codi^r[23:17:59] *** d0d0 has quit IRC[23:18:04] <c0ke> Well at the moment you walk off the edge of one map and appear on the edge of the next, I want the old map to scroll off with the new map scrolling on at it's edge in the direction you walk if that makes sense[23:18:58] *** domokato has joined #libgdx[23:20:00] <c0ke> I've had a bit of a mare with all this (gone refactor crazy) as it's a client and server situation and everything needs to be as atomic as possible, and phones suck so the map might take 5 seconds to load and all that nonsense :P[23:20:28] <c0ke> But all that's sorted, just thought it would be really cool to have transitions[23:21:05] *** Keniyal has quit IRC[23:21:23] <codi^r> I would aim for being able to render both maps simultaneously, but ofc that depends on your limitations[23:21:40] <codi^r> if there's enough memory etc[23:22:05] <c0ke> That was my initial thought but I am already being pretty heavy handed with peoples phones I think this might out of memory them :P[23:22:38] <codi^r> the problem with the fb idea is that this won't be animated as the old scene scrolls away[23:23:08] <c0ke> Yeah I'm not worried about that, it will be a fast transition and I won't render any NPCs or anything to it so it'll be obvious it's a courtesy transition[23:23:28] *** domokato has quit IRC[23:25:51] <c0ke> Early start tomorrow and work is heavy so I don't think I'm in the right mindset for ripping my stuff apart but thanks for the point in the right direction, I think I'll move my camera position code into a 'System' tomorrow and spend a few hours playing around, see what I can achieve.

It seems that it's happening randomly though, probably because of things sometimes loading before others, I don't know. Ashley is kinda hard to debug.
