Hi guys! It's my first time posting here, so forgive me if I make some obvious errors or wrong assumptions. Now, my real question: I mod Halo CE (the game for PC) a lot, and I love to use its nice and easy editing kit to make beautiful effects. To do that, however, I need to pre-render some particles. I've understood the process used by later Halo games to render them, and I know how to make an algorithm to achieve that (but I don't know how to turn it into code yet). Basically it takes 2 images as input: the actual particle bitmap from which it should start, and then it copy-pastes the bitmap as many times as needed, making it fade every frame according to the gradient bitmap. Problem is: I don't know where to start. I know C++ and C (but not C#, which is a problem), so may somebody redirect me to the right places where to start looking for code? CodeLab can't help me here, and I couldn't find any source code for the only plugin I have ever seen taking external images as input (I'm talking about the Alpha Mask one).
