Particle Basics

So I was asked by many people about particle creation and workflow since the tutorial provided by Steam (or someone that is put on the Valve developer site) seems to stop at one point. Since I can't do too much of complicated work today, I will write some tutorials to get people started diving into particles.

Also note that some particle system implementations might have Lua scripting involved if it is a very complicated system. So a little basic Lua scripting will help you every now and then.

Here is the list of functions covered in this tutorial:
