Is there an AI setting to make the AI harder/better then the default (without having to customize it)?

Im halfway through making my first map (Coop[terran] vs Computer[zerg]) but the AI is inept and near comatose.

If theres a built-in setting that can be adjusted let me know.

(or a fan-made ai thats easy to add to a map)

Code

Copy and then paste trigger code into http://vgshorts.com/BBCode/BBCode3.php to see it normally.

That (looks like it) should work; just change the player parameter.

I remember seeing a function where you could set the APM of a Computer player.

The APM is only generally used for higher level or custom AI computer players though. It's mostly used as a limit to say that they can't preform more than this many actions at a time, as to prevent heavy micro, or whatever the case is.
