Hey Ludum Darers!<\/p>\n

I’ve been roaming in the wonderful world of OpenGL and I’m super close to making a really nice library that I’ll be able to use for the compo!<\/p>\n

However, I am in need of some help. If anyone has experience with LWJGL\/OpenGL and some free time, I’d really appreciate it.<\/p>\n

 <\/p>\n

I’ve been having problems using Vertex Buffer Objects. because the system throws an exception saying “Cannot use offsets when array buffer object is disabled” whenever I try to call glPointer operations. \u00a0(See line ~845)<\/p>\n

I’m clueless as to what this means, being that there is no GL Enum called ARRAY_BUFFER_OBJECT. Any help on what it might mean or what I’ve coded wrong would be nice.<\/p>\n

 <\/p>\n

Also, I’ve been having problems with FrameBuffer objects. They never seem to render to anything at all. The class is at line ~1355<\/p>\n

I’m pretty sure it’s within the Three.GL.FrameBuffer class, but I can’t seem to find the problem.<\/p>\n

 <\/p>\n

Yes, the class is called “Three” until I can think of something better.<\/p>\n

To use the library, \u00a0just copy the class file into your game, create a class that implements Three.GameObject, then call create(params), defineGameObject(GameObject), and start() to begin.<\/p>\n

Three.GL houses all kinds of shortcuts for OpenGL, Three.AL does the same for OpenAL, and Three.Util is a little module I’ve created for containing anything that I might find useful.<\/p>\n

 <\/p>\n

 <\/p>\n

Please tell me any solutions in the comments. I’ll post a final edit of the class file either when it’s fixed or the day of the competition.<\/p>\n

Thank you and good luck!<\/p>\n
