Hello! I'd like to help but your request is very vague. We know absolutely nothing about your map or what a Bot means exactly.
Remember, you can make A LOT of different kinds of maps, there's mobas like DotA, tower defenses, survival arenas, custom melee maps that play like the standard game, etc. All of these play differently and could have different kinds of "bots" which I assume are AI controlled Players, aka
Computers.
So what exactly is a bot? Is it an AI controlled Computer player that has a single Hero like in DotA? Is it a Computer player that runs through the standard AI script for building a base, mining gold, and training units?
Or are you simply asking how to add Computer players to the map in the simplest form? Scenario/Player Properties:
