December 29, 2013 [00:00:31] <Clome> So, in all those tutorials where they clean up stuff(liek shaders, buffers, ...) after being done, it is just a matter of good practice?[00:01:49] <MatthiasM> no, it will just take longer for your program to close[00:03:56] <Clome> It will take longer if I let OS cleaning it up or if I manually do it.[00:04:59] *** meoblast001 has joined #lwjgl[00:05:12] <MatthiasM> the driver/OS has to manage per app resources anyway - and when the app terminates it can do a batch cleanup without checking if anything is still in use[00:05:28] *** Agro has quit IRC[00:05:42] *** mylar has joined #lwjgl[00:05:50] <MatthiasM> http://www.youtube.com/watch?v=TxLMIEZzAnE[00:19:52] *** Norbo11 has joined #lwjgl[00:27:13] *** ZeuPiark has quit IRC[00:27:52] *** peter1_ has joined #lwjgl[00:39:34] <jezek2> Clome: it's good habit to do the destroying because you never know when you need to reinitialize stuff and adding it afterwards is more painful[00:40:28] <jezek2> in the same way don't give up on OOP because of "performance" or other stupid reasons :P[00:48:21] *** Agro has joined #lwjgl[00:48:53] <Clome> jezek2: to be honest I gave up on Java, not cuz of OOP but cuz of its verbosity. I am currently fidling with lwjgl in clojure.[00:49:36] <ra4king> if anybody wants to waste a little time: https://www.ra4king.com/wp-content/uploads/Multiplayer/Shooter.jar[00:49:44] <ra4king> multiplayer game I've made, me and a friend are in there[00:50:04] <jezek2> Clome: the verbosity is totally great for maintaining bigger programs over many years[00:50:40] <jezek2> Clome: had very unpleasant experience with python where reading (actually understanding) the code is very hard because of lack of verbosity (the types mainly)[00:52:05] <jezek2> literally I was lost on what types were operating on after 3rd line when reading some plugin source code in blender[00:53:45] <jezek2> I think so far my list of hardest to read languages are: a) C++ (when it's using lot of (mis)features), b) python and other "type"-less languages, c) C++ (when it's more decent :P), d) c# (it has too many exceptions to exceptions of rules and weird doing of things)[00:55:49] <jezek2> not sure about perl :P like if you refresh your memory on the syntax of some things it's pretty readable actually (or had luck to good code so far :P)[00:59:02] <jezek2> one always learns new tricks how to do bad C++, like this: http://www.pagetable.com/?p=250 (in the "How to Not Do It" section)[01:01:05] <Clome> To each its own. I can see the benefit of languages like java, c#, etc. when you have a bigger team and working on a bigger project, but for me, I found out that less I type need to type to do stuff, more productive I am and less bugs I have. I am usualy working on smaller project and for readibility I leave comments after a batch of related statements(usualy 3-5). That has showed to work great[01:01:05] <Clome> fo me. Can not stand it, to look at a class with more the 200 lines of code, full of getters an setters and at the end it doesnt do anything complex at all.[01:01:41] <Clome> less I need to type to do stuff*[01:03:07] <jezek2> haha, well smaller things are more ok, and yeah the setter/getter is not exactly the good part of verbosity in java :P[01:03:43] *** Jeanne-Kamikaze has quit IRC[01:04:04] <jezek2> one can (esp. in smaller project) use direct field access and refactor to use setter/getters when you need it only[01:04:05] <LepraHorst> ra4king: this game is really nice :) but its a bit laggy. is this just because of my ping?[01:04:09] <nbf> I love writing getters and setters[01:04:20] <nbf> they make me feel mportant[01:04:44] <jezek2> I like using them, makes the code somehow more uniform or something, less so to create them even when it's automated by IDE[01:04:48] <jezek2> it's still in the way[01:05:01] <nbf> yeah I wouldn't cry if they adopted C#'s approach[01:05:08] <ra4king> LepraHorst: yup, I limit the number of packets sent because of ping[01:05:15] <ra4king> LepraHorst: I got lazy and didn't add interpolation[01:06:02] <jezek2> nbf: C# approach is quite ugly though :)[01:06:21] <nbf> how would you do it[01:07:03] <jezek2> the way I've implemented in my lang is by having property keyword to mark simple properties directly in field declaration[01:07:29] <jezek2> and for anything more complex you just put in specially named methods get:nameOfProperty or set:nameOfProperty[01:07:36] <ra4king> holy shit JohnConnor has 1252 ping[01:07:48] <jezek2> and there is shortcut that you don't need to declare it as property if you have at least one of the setter/getter[01:07:59] <jezek2> you still need it if you want to add documentation to it though[01:08:05] <jezek2> I think delphi uses similar approach[01:09:30] <LepraHorst> ra4king: ok :) but its quite fun though[01:09:58] <ra4king> LepraHorst: surprisingly isn't it?[01:10:12] <ra4king> such a simple game I made as an afterthought to see if I could do networking[01:10:20] <nbf> jezek2: not bad[01:11:11] <LepraHorst> ra4king: yes, somehow it is.[01:11:19] * ra4king improves it[01:11:31] <nbf> realize it's a clone of the real DoodleJump[01:11:39] *** Dessimat0r has quit IRC[01:12:23] *** peter1_ has quit IRC[01:32:00] <nbf> I think I'm going to play some CS[01:32:16] <nbf> haven't played that in SOOO long[01:33:09] *** l3dx has quit IRC[01:41:26] *** l3dx has joined #lwjgl[01:41:26] *** l3dx has joined #lwjgl[01:46:01] <ra4king> nbf: what does doodle jump have to do with anything?[01:52:29] <nbf> my b I thought you were talking about the stuff from last night[01:53:00] <nbf> got I hate how horribly slow compiz is[01:53:21] <nbf> I can barely get playable framerates @ 2560x1600 with CS:Source[01:53:57] <nbf> this machine isn't exactly powerful and new but CS:Source is old as hell[01:55:30] *** meoblast001 has quit IRC[02:02:51] *** pangaea_ has joined #lwjgl[02:04:57] *** CLT|Stiotic has joined #lwjgl[02:05:00] <CLT|Stiotic> Hey[02:05:06] <pangaea_> hi[02:05:25] <CLT|Stiotic> can someone help me really quick, im struggling in drawing my world :/[02:06:56] <pangaea_> what is the problem?[02:09:08] <CLT|Stiotic> okay im trying to draw a 2d world via a tilesystem, I have an array list containing the Tiles(which have a posX a PosY a width and a height) so i make my game loop through the array list and fill the Floatbuffer with the position of my vertices then i use GlBufferData and then bind it to a Vao but it just gives me a black screen[02:10:48] <pangaea_> CLT|Stiotic are you using shaders?[02:10:57] <CLT|Stiotic> yes[02:11:11] <CLT|Stiotic> im passing a vec 3 in my shader and set the w to 1.0 in the shader[02:11:31] <CLT|Stiotic> I could draw a white triangle before with a simple buffer[02:11:43] <CLT|Stiotic> but since i got my world system it wont show anything[02:11:44] <pangaea_> have you checked for shader errors? like do you know if the shader are compiling correctly?[02:11:54] <CLT|Stiotic> yes[02:12:15] <CLT|Stiotic> http://puu.sh/61QPB.png does this look right?[02:13:24] <pangaea_> CLT|Stiotic is this for 2D game?[02:13:49] <CLT|Stiotic> yes[02:15:16] <CLT|Stiotic> wanna see my vbo/vao initialization?[02:17:36] <pangaea_> CLT|Stiotic how big is a tile in your game compared to the monitor? 10% of the monitors size?[02:17:49] <pangaea_> or are the tiles really tiny?[02:18:11] <CLT|Stiotic> Oh i didnt think of that... its just 10 by 10 and my monitor is quite big[02:18:38] <CLT|Stiotic> well didnt fix it :/[02:19:14] <CLT|Stiotic> http://puu.sh/61Rfy.png could this have any error in it? im kind of lost at the moment[02:21:30] <pangaea_> CLT|Stiotic where do you define worldData[02:21:30] *** l3dx has quit IRC[02:21:53] <pangaea_> is worldData just a Vertex?[02:22:01] <CLT|Stiotic> http://puu.sh/61Rr8.png[02:22:03] <CLT|Stiotic> its an array list[02:22:07] <CLT|Stiotic> of Type Tile[02:22:36] <pangaea_> can I see the Tile class?[02:22:49] <CLT|Stiotic> sure[02:23:09] <CLT|Stiotic> http://puu.sh/61RuS.png[02:25:19] <pangaea_> CLT|Stiotic your problem is .put how your using it.[02:25:54] <CLT|Stiotic> how should i use it?[02:28:29] <pangaea_> That isn't the important thing. For a 2D game at worst you have to draw 300x300 times, that is at worst and even then the fps would be a solid 60 fps.[02:28:43] <pangaea_> You should just have one tile, that you move around in the shader.[02:29:56] <CLT|Stiotic> thats actually what im trying to do[02:30:03] <CLT|Stiotic> but i need mutliple tiles[02:30:15] <CLT|Stiotic> how would i do it with 1 tile? lol[02:31:34] <CLT|Stiotic> for instance i have a house consiting out of 20 16x16 blocks and some of them are solid and some of them arent[02:31:40] <pangaea_> In your shader, you can set uniform for position. In your tile class, you would have one VBO[02:31:50] <CLT|Stiotic> Thats what im doing[02:32:21] <CLT|Stiotic> gl_Position = orthoMatrix * transformMatrix* vec4(position, 1.0);[02:32:58] <CLT|Stiotic> the problem is is that my vbo isnt displaying anything[02:33:00] <CLT|Stiotic> :/[02:33:13] <CLT|Stiotic> I think im filling the FloatBuffer in the wrong way[02:33:21] <pangaea_> CLT|Stiotic what is your draw method for tiles?[02:33:29] <pangaea_> oh you could try this[02:33:33] <CLT|Stiotic> glDrawArrays(GL_TRIANGLES, 0, 3);[02:34:41] <pangaea_> CLT|Stiotic no I mean you posted how you init everything. Are you making the vao every frame or something?[02:34:51] <CLT|Stiotic> nooo :)[02:34:57] <CLT|Stiotic> wait ill give you my main game class[02:35:31] <CLT|Stiotic> http://pastebin.com/MUFZUAZP[02:38:45] <pangaea_> CLT|Stiotic hmm well two problems firstly you need to put stuff like this http://pastebin.com/TMmaKDBn, You would need to change your attribute to make it work for 3 position[02:39:24] <pangaea_> the programs want 3 floats for position, but your giving it 9[02:40:12] <pangaea_> on glDrawArrays(GL_TRIANGLES, 0, 3); you don''t want that.[02:40:34] <CLT|Stiotic> glDrawArrays(GL_TRIANGLES, 0, 9); Like that?[02:40:36] <pangaea_> You want glDrawArrays(GL_TRIANGLES, 0, size); where size is how many triangles you have sent to it.[02:40:46] <CLT|Stiotic> oh yeah[02:41:06] <CLT|Stiotic> but right now its 3[02:41:09] <CLT|Stiotic> for 1 triangle[02:41:14] <pangaea_> CLT|Stiotic what GL_TRIANGLES tells it to take in 3 points.[02:41:16] <CLT|Stiotic> so just for the sake of testing 3 is okay right?[02:41:30] <pangaea_> well[02:42:37] <pangaea_> CLT|Stiotic but it not drawing because of the .put, you would have to do something clever with attributes if you wanted to do what you wanting to do.[02:42:58] *** Norbo11 has quit IRC[02:43:18] <CLT|Stiotic> http://puu.sh/61SF4.png does this look better?[02:44:15] <pangaea_> CLT|Stiotic that problem isn't really with that, it more this glVertexAttribPointer(0, 3, GL_FLOAT, false, 0, 0);[02:44:36] <CLT|Stiotic> cant i just set it to 9 ?[02:44:37] *** Gooogy has quit IRC[02:44:43] <pangaea_> CLT|Stiotic this mean it would only read 3 of the values put into the buffer.[02:46:30] <CLT|Stiotic> hm strange thing is I had it working[02:46:44] <CLT|Stiotic> without the world but just with a floatBuffer put Directly into my vbo[02:46:45] <CLT|Stiotic> http://pastebin.com/KYba7iNs[02:46:47] <CLT|Stiotic> like this[02:46:48] <CLT|Stiotic> it worked[02:46:55] <CLT|Stiotic> (also some color data but i removed that[02:49:17] <pangaea_> CLT|Stiotic what does that draw? one triangle?[02:49:26] <CLT|Stiotic> yes[02:49:51] <pangaea_> wait there[02:51:14] <CLT|Stiotic> wtf[02:51:15] <CLT|Stiotic> it works[02:51:18] <CLT|Stiotic> YUS[02:52:41] <CLT|Stiotic> thank you so much[02:52:48] <CLT|Stiotic> somehow you helped me :D[02:53:11] <pangaea_> what did you change?[02:53:30] <CLT|Stiotic> i said the attrib pointer back to 3[02:53:39] <CLT|Stiotic> used the put method i posted[02:53:43] <CLT|Stiotic> i dont know what i changed[02:53:47] <CLT|Stiotic> but it works now xD[02:53:53] <CLT|Stiotic> set* not said..[02:54:43] *** djdduty_ has joined #lwjgl[02:55:39] <pangaea_> I was just going to tell you to do that. It should work fine.[02:55:52] <CLT|Stiotic> oh and i removed face culling[02:56:02] <CLT|Stiotic> that made the final step towards working[02:56:52] <pangaea_> CLT|Stiotic does that actually make a difference, as aren't you doing clockwise rendering[02:57:19] <CLT|Stiotic> What?[02:57:41] <pangaea_> how your drawing the triangles they are oriented clockwise, so they shouldn't be culled.[02:58:07] <CLT|Stiotic> yep[02:58:41] <CLT|Stiotic> but i should better use indicies right?[02:59:50] <pangaea_> CLT|Stiotic for glDrawArrays you need to put in the size of worldData i.e. how many tiles there are[03:00:02] <CLT|Stiotic> i did[03:00:23] <CLT|Stiotic> glDrawArrays(GL_TRIANGLES, 0,World.worldData.size() * 3);[03:00:52] <pangaea_> through I think your better of using something like SFML or slick2d and not LWJGL. Like how your doing stuff now is slow. You need to batch up your world.[03:01:04] *** void256 has quit IRC[03:01:25] <CLT|Stiotic> i really dont want to use slick2d[03:01:31] <CLT|Stiotic> i want to create my own engine[03:02:23] <CLT|Stiotic> what does batching up mean?[03:02:30] <pangaea_> okay then I guess you should use LWJGL.[03:04:04] <pangaea_> CLT|Stiotic say the world was 10000x10000 tiles, you don't want to put that into a big VAO as you would at worst only see 100x100 tiles. Most likely you would see only 30x30 tiles. So you want to batch everything up into say 20x20[03:04:16] <pangaea_> tiles then you work out which ones are on the screen and render that only.[03:04:28] <CLT|Stiotic> oh chunks?[03:04:33] <pangaea_> yes[03:04:46] <pangaea_> most important thing in 2D engine.[03:04:54] <CLT|Stiotic> hmm[03:05:10] <CLT|Stiotic> sounds complicated[03:49:10] *** Sopheria has quit IRC[03:49:21] *** Nasco has quit IRC[03:50:21] *** Nasco has joined #lwjgl[03:53:12] *** LepraHorst has quit IRC[03:55:35] *** Raven67854_ has joined #lwjgl[03:58:25] *** Sopheria has joined #lwjgl[03:58:34] *** Raven67854 has quit IRC[04:15:50] *** Irrelium has quit IRC[04:18:53] <pangaea_> what type of networking library is good for LWJGL?[04:19:42] *** CLT|Stiotic has quit IRC[04:44:55] <nbf> pangaea_: LWJGL is mainly just bindings, so it doesn't have something like that[04:45:33] <nbf> there are quite a few java networking libs but what your app does influences the design of the networking infrastructure[04:45:55] <nbf> so one size doesn't usually fit all, unless you're doing something simple[04:46:30] <pangaea_> http://www.lwjgl.org/wiki/index.php?title=Links_and_Resources#Networking_Libraries oh it just in the wiki it has this.[04:49:03] *** Clome__ has joined #lwjgl[04:50:23] *** Clome has quit IRC[04:50:30] *** Clome__ is now known as Clome_[04:50:36] *** Clome_ is now known as Clome[04:52:25] *** Agro has quit IRC[04:58:54] *** Clome has quit IRC[05:00:39] *** Clome has joined #lwjgl[05:01:02] *** Cairaptor has quit IRC[05:01:26] *** Clome has left #lwjgl[05:02:23] *** Clome has joined #lwjgl[05:02:52] *** Clome has joined #lwjgl[05:12:36] *** Chris_Noob has quit IRC[05:18:01] *** Clome has quit IRC[05:37:15] *** Clome has joined #lwjgl[05:39:12] *** Clome has joined #lwjgl[06:17:47] *** pangaea_ has quit IRC[06:51:20] <nbf> gg anderson silva :([07:27:57] *** Raven67854 has joined #lwjgl[07:31:22] *** Raven67854_ has quit IRC[07:56:16] *** geekygenius has joined #lwjgl[08:59:52] *** meoblast001 has joined #lwjgl[09:14:41] *** meoblast001 has quit IRC[09:27:37] *** peter1_ has joined #lwjgl[09:30:02] *** peter1_ has left #lwjgl[09:46:05] *** ZeuPiark has joined #lwjgl[09:49:15] *** mylar has quit IRC[10:17:55] *** geekygenius has quit IRC[10:18:00] *** Jeanne-Kamikaze has joined #lwjgl[10:35:13] *** l3dx has joined #lwjgl[10:35:14] *** l3dx has joined #lwjgl[10:47:49] <lwjglbot> lwjglforum: Re: How to move LWJGL's window after it has been created? <http://lwjgl.org/forum/index.php/topic,5278.msg28153.html#msg28153>[11:00:09] <Clome> nbf: you just spoiled it for me, don`t do that again![11:12:01] *** ZeuPiark has quit IRC[11:15:56] <nbf> sorry[11:28:30] *** LepraHorst has joined #lwjgl[11:48:09] <lwjglbot> lwjglforum: [BUG] Display.setLocation regression in 2.9.0 (OSX) <http://lwjgl.org/forum/index.php/topic,5279.msg28154.html#msg28154>[12:12:55] *** Raven67854 has quit IRC[12:15:45] *** Raven67854 has joined #lwjgl[12:23:58] *** Clome has quit IRC[12:28:14] *** kevarh has quit IRC[12:28:49] *** kevarh has joined #lwjgl[12:29:00] *** Sopheria has quit IRC[12:37:12] *** bacil has joined #lwjgl[12:42:02] *** djdduty_ has quit IRC[12:42:20] *** djdduty_ has joined #lwjgl[12:42:56] *** djdduty_ has quit IRC[12:43:17] *** djdduty_ has joined #lwjgl[12:44:53] <bacil> Hello, could anybody help me solve a little problem w/ slick and deltatime please?
