it[00:03:57] *** Guest9444 has quit IRC[00:04:11] <JesusCM> the font is gargantuan and pixelated unless i scale it down a ton and make the parameter size rather large[00:05:35] <McDax> Hey, What I have to do if I want to have the Admob-Banner in the gameView as Window and not in a special view which fills the whole edge[00:05:48] <JesusCM> whoops it should be this http://hastebin.com/ijuquvuyam.avrasm[00:06:05] *** hydra___ has joined #libgdx[00:06:24] *** esvee__ has quit IRC[00:06:45] *** deniska has quit IRC[00:06:47] <bhldev_> evening[00:06:52] <bhldev_> how's everybody doing[00:07:02] <JesusCM> hi[00:07:14] <JesusCM> id be doing better if this stupid freeType font was stressing me out[00:07:22] <bhldev_> what's wrong with it[00:07:29] <JesusCM> http://hastebin.com/ijuquvuyam.avrasm[00:07:35] <JesusCM> its the size of jupiter on my screen[00:07:56] *** deniska has joined #libgdx[00:07:58] <JesusCM> unless i scale it down a ton like so : fontScore.setScale(0.01);[00:08:14] <JesusCM> but then of course being scaled it doesn't look very nice[00:08:46] <JesusCM> it also has very large pixels unless i have a large parameter size scaled down[00:10:12] <bhldev_> you sure it can handle otf?[00:10:15] <bhldev_> maybe try a ttf font[00:11:23] <JesusCM> i have otf for my labels and buttons[00:11:28] <JesusCM> its looks magnificient[00:11:41] <prophile> JesusCM: what are the camera coordinates of the corners of the screen[00:11:47] <JesusCM> i just draw it to the size needed and it looks perfect[00:11:49] <bhldev_> maybe just eat it and set scale to nothing and file bug report[00:11:54] *** pbsaint has quit IRC[00:12:04] <bhldev_> create reproducable test case[00:13:09] <JesusCM> y goes from -5 to 5 or so[00:13:17] <JesusCM> and x is about -10 to 10[00:14:33] <prophile> do fonts assume pixel coordinates?[00:15:25] <JesusCM> the positioning works fine[00:15:32] <JesusCM> its just the size[00:15:37] <prophile> right[00:15:45] <prophile> which may work based on an assumption of pixel coordinates[00:16:03] <JesusCM> oh thats true[00:16:20] <prophile> in which case perhaps scale by (10 / Gdx.graphics.getHeight())[00:16:25] <prophile> and see if it's about the right size[00:16:43] *** Sietsem has quit IRC[00:16:52] *** Hronom has quit IRC[00:16:55] <JesusCM> i can get it the right size[00:17:04] <JesusCM> but scaling makes it look not so nice[00:17:19] <prophile> then work backwards[00:17:45] <prophile> use a pixel coordinate system for fonts and do your positioning with that[00:18:59] <JesusCM> how would i do that[00:20:47] <prophile> use a projection matrix for that[00:20:54] <prophile> *a different projection matrix[00:21:08] <Xoppa> fonts should always be rendered at pixel perfect projection[00:21:55] <Xoppa> just use an othographiccamera with not arguments for the constructor[00:21:59] <prophile> actually Valve have some fancy way of scaling text without losing detail[00:22:00] <Xoppa> *no[00:22:47] <robitx> prophile: something else than distance field fonts?[00:22:49] <prophile> http://www.valvesoftware.com/publications/2007/SIGGRAPH2007_AlphaTestedMagnification.pdf[00:23:14] <prophile> robitx: probably not, this is distance field magic[00:23:26] <robitx> its not magic[00:23:43] <JesusCM> ill try that Xoppa[00:23:50] <prophile> no, it's not, but it is rather elegant[00:24:50] <robitx> well it is with libgdx, if you decide to use ui elements, since you have to overide practicaly all of them...[00:24:56] <JesusCM> oh looks like the constructor needs an argument[00:25:19] <Xoppa> then pass it the actual width and height of the screen in pixels[00:25:54] <JesusCM> thats what i was thinking[00:26:57] *** GhostNr1|2 has joined #libgdx[00:29:23] *** GhostNr1 has quit IRC[00:29:49] <JesusCM> not sure which of these methods[00:30:41] *** alket has quit

field fonts, while they sound nice in theory, end up being... less than ideal[00:36:58] <aegamesi> They lose a significant amount of detail around the corners, and it makes it look pretty bad[00:37:19] <aegamesi> the paper talks about a way to fix it, but only barely, and not enough to actually implement a fix[00:37:44] <robitx> aegamesi: what was the base size for the font you used?[00:38:02] <aegamesi> I don't quite remember, I switched to freetype a little while ago[00:40:41] *** pmartino has joined #libgdx[00:40:59] <pmartino> im getting an error when i run an android program[00:41:04] <pmartino> Unable to execute dex: Multiple dex files define Lnet/dermetfan/utils/Appender;[00:43:50] <Xoppa> pmartino, you're referencing a project (e.g. jar dependency) in both the core and android project?[00:44:05] <pmartino> hmmm[00:44:11] <pmartino> i dont remember doing anything like that[00:44:17] <pmartino> where do i check[00:44:25] <pmartino> the gradle files?[00:45:11] <Xoppa> right click the project in eclipse, click properties and then it think it is called something like build dependencies[00:46:24] <Xoppa> euhm "Java build path"[00:46:56] <pmartino> ok[00:46:59] <Xoppa> then the "Order and Export" tab is probably the easiest to check[00:47:13] <nicklatech> lets say i have a sprite then i set color with a 50% alpha but no color information. what will happen? will the sprite be 50% transparent?[00:47:16] *** pwnz has joined #libgdx[00:47:42] <pmartino> what am i looking for[00:48:11] <Xoppa> a reference listed on both the core and android project[00:48:33] *** JesusCM has quit IRC[00:48:41] <Xoppa> most likely the dependency that contains Lnet/dermetfan/utils/Appender;[00:48:52] <pmartino> do i get rid of one of them?[00:48:56] <Xoppa> nicklatech, yes[00:49:03] <nicklatech> Xoppa: thanks man[00:49:07] <Xoppa> default color is white[00:49:28] <Xoppa> there's no such thing as "no color information" for sprite[00:49:37] <nicklatech> k[00:49:59] *** Arbos has quit IRC[00:50:05] <Xoppa> pmartino, yes[00:50:28] <Xoppa> however, if you're using gradle then you will have get rid of them in the gradle.build file[00:50:43] <Xoppa> (as well)[00:51:03] <Xoppa> *build.gradle[00:52:13] <pmartino> alright let me try erasing some lines[00:52:16] <pmartino> on the gradle project[00:52:37] <pmartino> im removing the one from the android path[00:52:57] <pmartino> stab in the dark[00:53:57] <Xoppa> sounds like a plan, if the core project already contains that dependency (and exports it) then there's no need to depend on it for the android project as well[00:54:55] <pmartino> still gives me an error :([00:55:21] <pmartino> i guess i need to remove all the duplicates[00:56:32] *** nicklatech is now known as nick-coden[00:57:41]

yes[05:46:42] <TEttinger> it will only work on windows and has speed issues[05:46:51] <OxCA2> really?[05:47:04] <OxCA2> could you elaborate on the speed issues[05:47:35] <TEttinger> I recently ported from C#/libgdx to Scala/libgdx, the lib it uses to get all of the java lib accessible by libgdx is called IKVM.[05:48:02] <TEttinger> IKVM has a lot of translation it needs to do to get things to work on .NET[05:48:39] <TEttinger> IKVM may work with older versions on mono, but recent ones do not because of how IKVM tries to load the libs that LWJGL needs[05:49:21] <OxCA2> darn, wanted to learn c# but I have no interest in MonoGame[05:50:14] <OxCA2> have you ever used MonoGame?[05:50:45] <TEttinger> no, I wasn't sure if it was a good idea for me. libGDX does a bit more, I think.[05:51:50] <KicStart> TEttinger: is there any value in writing a cocos2d ccb loader in libgdx?[05:51:50] <OxCA2> yeah, utility classes + disposable resources[05:52:24] <TEttinger> I don't know what CCB is, KicStart[05:52:39] <KicStart> TEttinger: it's a cocosbuilder sprite format[05:53:03] <TEttinger> I'd kinda doubt it unless you're porting something[05:53:16] <KicStart> I'm always porting something[05:53:20] <TEttinger> or if you have a lot of CCB sprites[05:56:04] <Aryantes> If it were me, I would instead write something that converts ccbs to a libgdx format, outside of libgdx itself[05:56:59] <KicStart> That makes sense[05:58:12] <KicStart> I see like ccb to tmx[06:01:37] <OxCA2> TEttinger how is Scala with libgdx[06:03:16] <TEttinger> OxCA2, it's quite good. I intend to write my next project in Clojure though since the tooling's improved a lot since I last used it. The main reason I used Scala was how close the feature set and code structure is to C#, but Clojure is more the way I think. and #scala here on Freenode is fatalistically obsessed with how obsolete they see their language being[06:03:46] *** Tann_ has quit IRC[06:03:53] <OxCA2> lmao[06:04:39] <TEttinger> but yeah, scala's nice and fast for what I need to do, it has more features than probably are needed, and the IDE support is great in IntelliJ[06:05:31] <TEttinger> clojure has a better wrapper for idiomatic usage of libgdx in their style, Scala you just call libgdx stuff directly and it pretty much matches up.[06:05:33] <OxCA2> Would writing a game in Clojure have performance issues?[06:06:14] <TEttinger> OxCA2, I had some, but I think it was related to how I wrote my game (pathfinding on a large map for all monsters in a very brief span of time)[06:06:21] *** Beardragon has quit IRC[06:06:40] <TEttinger> in particular, some useful tools came in after I had written my game in clojure[06:07:05] <TEttinger> reducers and core.async would have likely helped a lot for speed and code clarity, respectively[06:08:57] <OxCA2> Were there any issues in regards to writing a game in a purely functional language?[06:09:51] <TEttinger> so my game used clojure 1.4 I think, version 1.5 added a lot of features but a big one was being able to shortcut stop certain functions running on sequences once you find a value you want. 1.6 added reducers, which make the specific function much faster, the one I mentioned on sequences (called reduce, it takes a sequence and runs a function on it to get one value out)[06:10:35] <TEttinger> OxCA2, play-clj is the wrapper I mentioned for libgdx, and it's amazing. it's basically writing clean clojure code with almost no calls outside of the language in your stuff[06:11:49] <TEttinger> it uses a neat hackish trick internally (never exposed) that lets you just return a list of entities and pass it to certain functions (like in ashley or artemis, it's an entity-driven style) and it will update the collection of entities[06:12:00] <TEttinger> so it seems pure even though it isn't really[06:12:19] <OxCA2> all this sounds interesting. thanks for all of the info[06:12:21] *** Burnrate has quit IRC[06:13:06] <TEttinger> since clojure's collections are persistent, you can change one entity and update it in the whole list, and it doesn't create a whole new entity list, just updates it without destroying the old one[06:13:29] <TEttinger> there's some crazy technique used to share structure of collections[06:14:02] <TEttinger> clojure will be somewhat slower than scala or java but it tends to be much shorter code. optimizing it is a pain though[06:15:33] <TEttinger> OxCA2, I would recommend starting with Scala tbh, it's a very good intro from java-style to more functional-style code.[06:16:28] <TEttinger> downside is the scala community is not great on IRC, though ajhager helped me a lot here and on github, and the learning resources aren't often up-to-date[06:16:41] <OxCA2> Yeah, I've never really learned a functional language before[06:16:53] *** ilar has quit IRC[06:17:12] *** BlueProtoman has quit IRC[06:17:51] *** hackhalo2 has quit IRC[06:18:09] <OxCA2> Scala looks kind of, intimidating[06:20:18] *** Burnrate has joined #libgdx[06:23:05] <TEttinger> OxCA2, yeah I basically code imperative scala with some functional features. it's adaptable.[06:23:25] <TEttinger> http://nurkiewicz.github.io/talks/2014/scalar/#/16 <-- I have used maybe two of these parts of the typesystem[06:24:29] <TEttinger> that's a good talk, and I actually understand some of why people be hatin' on scala now. it's still a good choice if you're used to C# or Java[06:25:41] <OxCA2> how do you feel about the dozens of other JVM languages?[06:25:55] <OxCA2> i happened to spend most of my day checking some out[06:27:48] <TEttinger> clojure is by far my favorite. it's also totally different from all of them but the other JVM lisp dialects, like one Common Lisp dialect that might be called Clozure (confusing name...)[06:28:17] <TEttinger> http://tpolecat.github.io/assets/list.png Scala's collections API leaves a lot to be desired. this is the inheritance tree for what implements parts of List[06:29:09] <TEttinger> clojure took me a long time to learn, but there's better books now and in particular 4clojure is an awesome sorta koan site.[06:29:32] <TEttinger> I still write hackish clojure but that's fine for games[06:30:16] <OxCA2> yeah[06:30:29] <OxCA2> do you work as a programmer?[06:30:46] <TEttinger> keep in mind, clojure is absolutely not for everyone. a lot of people don't like to think the way it encourages you to think about programs (data-based, as I see it).[06:31:15] <TEttinger> no, I'm purely a hobbyist, but I'm racking up plenty of experience helping out on #clojure and here :D[06:32:04] <TEttinger> the cool thing about lisp/clojure being data based, though -- code is data too.[06:33:24] <OxCA2> what do you mean? kind of like reflection?[06:33:50] <TEttinger> not at all. you know how lisp code is wrapped in parentheses? (+ 1 2 3)[06:34:13] <TEttinger> () is how you construct a list, and it just happens to call the first element of the list as a function on the rest[06:34:31] <TEttinger> lisp = LISt Processor[06:35:12] <OxCA2> oh, yeah.[06:35:28] <TEttinger> so once you realize that, you realize you could take (+ 1 2 3) and if you don't evaluate it right away, you could decide to change + to * using a kind of code called a macro (unrelated to C/C++ macros)[06:35:57] <TEttinger> or you could wrap every function in a timer to log how long it takes during debugging[06:36:40] <TEttinger> this technique is used a lot internally by clojure libraries and you don't need to understand it to use it (I have written maybe 1 macro, ever)[06:37:13] <TEttinger> leveraging libgdx is the biggest reason I stay on the JVM[06:37:32] <TEttinger> it's really unparalleled for open source gamedev[06:37:45] <OxCA2> yeah[06:37:58] *** Rattus has quit IRC[06:38:49] <TEttinger> so here's a cool scala and clojure feature that you can get right away: futures. say you have some code that you know will take a long time, like generating dozens of detailed enemies for the next level before you get there.[06:40:36] <TEttinger> in java, you'd probably write it on the same thread first, find it locks up that thread when it happens, and spend a while making sure that it runs on another thread using locking. in clojure, unless you're doing nasty stuff with interop or trying to update the graphics outside of render (BAD), the "purity" or approximation to it makes this simple[06:41:20] <TEttinger> (def make-monsters (future (process-next-room)))[06:42:03] <TEttinger> when you need the next room, you can get the results of the function in the future, process-next-room, by just using @make-monsters at a later point.[06:42:29] <TEttinger> it transparently calculated the monsters on another thread, and blocks only if you need them right away[06:42:55] <TEttinger> scala is basically the same deal. it has very similar Futures with a different syntax[06:43:26] <OxCA2> wowww[06:43:50] <TEttinger> I used it actually to run a slow java function on another thread in my clojure game[06:43:52] *** LiquidNitrogen has joined #libgdx[06:44:08] <TEttinger> it turned out it wasn't even necessary in scala because of other performance improvements I had made[06:44:51] <OxCA2> that sounds like a great feature for games[06:45:13] <TEttinger> of course reading Java is a must for libgdx since that's what the source is in, and the open source is a huge advantage[06:47:20] <TEttinger> yep. I mostly use clojure these days for data tweaking. LiquidNitrogen I made some tiles for his game using java's AWT image lib and clojure to generate specific combinations of "this tile has these kinds of corners" -- it was, lets's just say, a lot shorter for that task.[06:47:40] *** KicStart has quit IRC[06:47:44] <TEttinger> then LiquidNitrogen decied to make the tiles simpler and didn't need it :P[06:48:51] *** KicStart has joined #libgdx[06:53:35] <OxCA2> hey i gotta go. thanks for all the info TEttinger[06:54:33] <TEttinger> cool[06:54:36] <TEttinger> good luck![06:55:12] <LiquidNitrogen> hello[06:55:23] *** OxCA2 has quit IRC[06:55:25] <TEttinger> hallo[06:56:01] *** pmartino has joined #libgdx[06:56:36] <LiquidNitrogen> my stupid game is nearly finished TEttinger. then back on track with real work[06:56:44] <TEttinger> heehee[06:56:49] <TEttinger> chainsaw cat?[06:56:58] <TEttinger> I like the idea a lot[06:58:37] <LiquidNitrogen> its more entertaining that i had hoped it would be[07:03:30] *** pmartino has quit IRC[07:03:45] *** pmartino has joined #libgdx[07:10:27] *** Fulcano has quit IRC[07:24:28] *** mkc has joined #libgdx[07:27:00] *** icbat has quit IRC[07:37:11] *** nick-coden_ has quit IRC[07:41:05] *** nick-coden_ has joined #libgdx[07:43:36] *** doodli has joined #libgdx[07:51:01] <doodli> So for best practices: It is recommended to keep creating new objects (e.g. Vector2 v = new Vector2()) outside of the Render() loop right? What about (float f = 13 + 37;)? Is that counted as "creating new object"? Or (float[] f = polygon.getVertices;)? Thanks for answering, Im confused . . . . .[07:52:59] <doodli> Another example: I need to do this "float d = Intersector.distanceLinePoint(vertices[2], vertices[3], vertices[4], vertices[5], vertices[0], vertices[1]);" in the render() loop, but not sure if declaring the float d as a class variable before would make a difference[07:53:38] <boog> float is primitive so it doesn't cause the garbage collection[07:54:48] <doodli> Okay so only Object are relevant? Or primitive values and arrays are safe from "the rule"?[07:54:50] <boog> it doesn't matter if you do it in render or not specifically, just don't do it every frame. Pool objects instead of recreating them if you can.[07:55:24] <boog> array is an object not primitive, though it can have primitives as elements[07:55:44] <doodli> i meant primitive arrays like "float[]"[07:55:50] <doodli> that is primitive right?[07:56:15] <boog> no but its elements are. this will cause gc: new float[]{}[07:56:29] <boog> just setting its elements will not[07:57:33] <doodli> ohh, ok. All clear now. Im doing set() in the render loops for the object (i.e. vector2.x = 10; and float[] = something;) and declare them as class variable before that. All primitives is safe in loop[07:57:37] <doodli> Thanks boog![07:58:53] <boog> np. the key is the "new" keyword really. and then when you're done with the object you 'new'ed, it is queued for gc.[07:59:58] <doodli> yeah, but i didnt suspect the float[] is an object (because of the lower case). Thanks for pointing it out[08:02:00] *** vestu has joined #libgdx[08:02:29] <boog> look out for the 'new' there too. you have to do "new float[N]" or else you get NullPointerException. primitives don't get NPE[08:02:31] *** slebed has joined #libgdx[08:03:40] <boog> usually if you do that you're doing it when setting up your objects, not during render loop[08:04:40] <doodli> i thought primitives (int, float etc. ) starts with null instead of 0 too?[08:05:17] <boog> you thought wrong ;)[08:06:09] <doodli> it must have been in C. yay learn new stuffs ty[08:06:10] <aegamesi> doodli: polygon.vertices is just member access, and doesn't create a new array[08:06:25] <aegamesi> doodli: but polygon.getVertices(), a method, *might*. You don't know unless you look at the source (or the docs specify)[08:07:37] *** slebed has quit IRC[08:07:41] <boog> i think in C the problem is you just don't know what data had been written there so you better overwrite it. java guarantees primitives to be zero as far as i have always used it.[08:08:40] *** kamiz has quit IRC[08:09:03] <doodli> hmm aegamesi, unfortunately .getTransformedVertices does indeed create new array. But i need to do it anyway..[08:09:11] <aegamesi> ()[08:09:29] <aegamesi> getTransformedVertices()! be careful, people might assume you're taking about a variable. Although the "get" suggests otherwise[08:10:54] <doodli> yeah sorry, i subconsciously assumed everyone knows the lib inside out . (been coding for 24hrs :p )[08:11:52] <doodli> yes boogie i think most OOP give u clean primitive now i think of it[08:12:32] <boog> this line in getTransformedVertices() if (worldVertices == null || worldVertices.length != localVertices.length) worldVertices = new float[localVertices.length];[08:13:07] <boog> only does the first time or if the polygon's number of vertices has changed since last time worldVertices was used.[08:13:13] <boog> not every call[08:14:52] <doodli> hmm. I think if I really really need it I can do the calculation in the loop without creating new object. Not sure if that is worth it or the calculation will outweighs it. But anyways like you said it is only created for the first time and my tile map should not change[08:16:27] *** nick-coden__ has joined #libgdx[08:16:27] *** nick-coden_ has quit IRC[08:16:47] <doodli> well you see aegame+si (sry dont wanna nudge you) everyone DOES indeed knows the lib inside out :D[08:17:27] <boog> it's easy to pull up the source code on github and check the class[08:18:31] <doodli> come on BOOG, it hurts not to admit that the libgdx community is AWESOME![08:19:09] <boog> true[08:20:59] <aegamesi> doodli: this principle holds true for almost everything: don't prematurely optimize. creating objects is fine. Don't do it too much, and avoid it if you can.

BAM it's final![08:29:34] <noone> I mean the compiler[08:30:03] <boog> if you call it final and don't assign it in the constructor or at declaration it will be a compile error[08:30:21] <noone> I'm talking about method parameters[08:30:43] <doodli> btw noone i saw xoppa added new bullet test cases are those from you?[08:30:59] <doodli> updated*[08:31:29] <boog> you can reassign a method parameter in the method unless it's declared final in the method sig[08:32:17] <boog> doesn't mean you're reassigning it for the caller's reference though[08:32:53] <noone> boog: yes, but if you create an anonymous class in that method, for example an EventListener in scene2d, and you want to use a parameter of the outer method, then it needs to be declared final before you can do that[08:33:18] <noone> but why do I have to write "final" there myself?

is probably to run the tests and uncomment and change that path to the path of your dll[16:07:42] <Xoppa> noone, then if that runs (using the debug dll that you've compiled) then you need to attach

what is it you're unprojecting?[16:09:53] <Xoppa> touch coordinates don't have a z coordinate[16:10:35] <Xoppa> FightingCat_, you probably don't want to use unproject for that, see

between 0 to 1 to decide which plane to unproject to.[16:11:24] <noone> FightingCat_: use a Ray, and do origin.add(direction.nor().scl(20))[16:12:08] <FightingCat_> Actually,there is no object in my

point me an article or something on "Why isn't LibGDX a game engine?"[18:48:03] <gentlemandroid> What a strange article that would be[18:48:16] <unksafi> I know it's a framework, and i've read somewhere that it only lacks the "toolset" to become a game engine[18:48:32] <unksafi> but i didn't understand...[18:48:36] <ocirne23> there is no definition for game engine[18:48:41] <unksafi> what kind of "toolset" ?[18:48:47] <gentlemandroid> Having a toolset seems like the Unity definition of a game engine[18:48:49] <ocirne23> but most people define it as something that has a gui[18:50:17] <gentlemandroid> Are you writing a paper or something?[18:50:24] <Xoppa> iirc andengine is considered an engine and imho the biggest difference is that it very restrictive (forces you to do things in a specific "magical" way) while libgdx is open and let you keep control[18:51:00] <gentlemandroid> Libgdx should have put engine in its name, could have been a game engine[18:51:45] <unksafi> Yes, i'm writing a paper.[18:51:54] <ocirne23> you can call any framework an engine[18:52:12] <ocirne23> doesnt make it an 'engine'[18:52:20] <gentlemandroid> I mean every game is it's own engine basically[18:52:45] <gentlemandroid> Engine is kind of a dumb word for middleware[18:53:37] <ocirne23> unreal engine, cryengine, unity are examples of engines[18:53:50] <unksafi> and why?[18:53:58] <unksafi> simply becasue they have a GUI ?[18:53:58] <gentlemandroid> They restrict you[18:54:11] <ocirne23> they dont nessisarily restrict you[18:54:28] <ocirne23> its more about how involved a programmer has to be[18:54:29] <gentlemandroid> They do unless you want to rewrite large parts of them yourself[18:54:37] <Aryantes> higher level of abstraction = more restriction = opinionated development = less emphasis on programming for user[18:55:04] <Aryantes> I think a gaming 'engine' would be one that leans towards this higher level of abstraction and users provide more content and logic than actual programming[18:55:09] *** deepinthewoods has joined #libgdx[18:55:23] <ocirne23> you can create a full game in ue/ce/unity without writing a line of code in the language the engine was made in[18:56:01] <ocirne23> id say thats a decent definition for engine[18:56:15] *** pmartino has joined #libgdx[18:56:16] <ocirne23> using the same language/abstraciton level as the thing itself == framework[18:56:18] <ocirne23> not == engine[18:56:19] <ocirne23> D: ?[18:56:24] <gentlemandroid> Engine didn't really mean middleware for a long time[18:56:32] <gentlemandroid> It just meant the underlying tech for an interesting game[18:56:35] <ocirne23> yeah, problem is that there is no actual definition[18:56:54] *** nepjua has joined #libgdx[18:57:01] <gentlemandroid> When companies with great engines started licensing them out it kind of became a term for such middleware[18:57:40] <ocirne23> yeah[18:57:52] <ocirne23> not nessicarily a bad thing though[18:58:15] <ocirne23> necessarily*[18:58:17] <unksafi> i liked that explanation .. thanks Aryantes[18:58:36] <gentlemandroid> I think in it's most basic terms it operates like an actual engine, munching assets and logic and pooping out exhaust fumes and happy funtime experiences[18:59:01] <ocirne23> in basic terms it also operates exactly like a framework/library[18:59:23] <gentlemandroid> Those terms are sissy terms though[18:59:43] <unksafi> ok. thank you all very much ... i'll get back to my paper... :p[18:59:56] <ocirne23> when the thing comes as a .library(jar) file, which is used in your own project like any other library[19:00:02] <ocirne23> its safe to say its a library and not an engine[19:00:59] <gentlemandroid> Nebulous[19:01:13] <ocirne23> it provides an amount of prewritten code in the language you develop your game in[19:01:18] <ocirne23> sounds like a library to me[19:02:44] <ocirne23> if it was an application you run, do stuff in, and it poops out a game[19:02:51] <ocirne23>

applied[19:45:22] <Xoppa> F = m * a, a = m/s/s[19:45:39] <Xoppa> then you cant have a constant velocity[19:46:52] <kojjootti> the velocity of the gravity is constant, right=[19:47:00] <Tomski> eh[19:47:18] <Xoppa> o.O gravity is an acceleration, so it cant be a constant velocity[19:47:21] <Tomski> acceleration due to gravity is very roughly constant[19:47:47] <davebaol> xoppa: the body

<davebaol> the jump will last[20:04:14] <Tomski> The initial velocity do you mean?[20:05:03] <Xoppa> setting the velocity (or applying an impulse) will give better results then applying a force[20:05:16] <Tomski> Or how to calculate the force/impulse to give a particular inital velocity?[20:06:58] <davebaol> the body is already moving with the correct planar velocity (speed and direction) when it reaches the jump point[20:07:14] <davebaol> I want to apply a vertical force/impulse to make it jump[20:07:50] <Tomski> So you have a desired height that you want it to be able to
