Particle Maker is a STOOL capable of creating user-defined particles.
You can create your own particles, set their color, size, sprite, gravity, motion and much more.
This stool is a modification of Robbis_1's Particle Maker to make it work with the new Garry's Mod code.
Robbis_1 created the base code, I added a lot of tweaks and made it gmod 13 compatible.
