Hey, i'm still working on a single surface particle system, but i need to check a few thing :)
1. When i load in the texture i want for the particles, i load them in as an unanimated texture, formatted like an animated texture, but just loaded using loadtexture?
2. Then when i want to animate a particular quad, i simply adjust the uv co-ords for that triangle?
3. I need to know if using sin and cos are slow? I'm using them constantly and need any feisable speed ups i can get.
4. I assume that when a quad isn't being used, i adjust the uv co-ords so that no tetxure is showing?
5. I read something a while back about calling clear surface, and building the quads back from scratch every frame. Think i read that from Anthony Flacks post about his game.
Sorry about the large number number of questions, but i feel like i'm learning alot jumping in with this stuff:)
