HOW TO FIX?!

Plz answer

Enveroiment>Global Variables>General>+Add new>Key:(name)>DataType:player>Computer 3 (AI)>Save,and when you go to make a object,choose this global variables.

you gotta add something to general XD player>computer 1(or any other)

you can change map with tiled or modd editor both work fine
