I see much people have problems with modding Powder Toy, so I make FAQ for this.
Project installing
Most of problems is how to set project.

How to set up project?
1. This is descripted on wiki, link: https://powdertoy.co.uk/Wiki.html?id=win32_code_setup

Project doesn't find libraries.
1. Check for " in additional dependencies. Sometimes wiki changes " to ”, so change ” to ".
2. Don't put directory "Source-Required" to project directory, but put here directories in "Source-Required".
3. If project still doesn't find libraries, put them in the "system32" directory.

Project can't include header, but I have them in project.
1. To Include Directories add "includes" directory. (but no from "Source_required" directory, but from directory like this - FacialTurd-ThePowderToy-<number>

Coding

I want to code particle, but I don't know variables in source and what them means.
