I decided to start a topic for discussing this PAWN element, this is partially a tutorial but it's not actually designed to tell you exactly how to use it. There has been a slow, self-reinforcing, increase in the development of code using "#emit", so this topic is to collect together some of the developments already found and discuss future ones. Further to the disclaimer above:
If you are writing a gamemode you probably don't need this.
If you are writing a filterscript you probably don't need this.
If you are writing a library you probably don't need this.
If you are looking to optimise your mode this is not the way to go.
