Ok, i have 3 ideas to add.
1) Effect, Effect2, Effect3
why game need it? - non-visual effect for mini-games devs, very useful!
2) Testobj, Testobj2 ... Testobj5
why game need it? - objects that can be turned to other objects. Isn't is useful?
3) Pathfind
why game need it? - cuz why not. we have "follow", which "does" same thing. Better thing for AI devs
thank you for reading if you did!
