Disable Creep Ai from casting spells

Is there any way to disable computer players from using spells. In my map, i have computers, that give shared control to its user allies. But it seems that the heros controlled by the computers just cast spells whenever.

There's no way to know which player ordered the casting of the spell if ur using share control.

Make custom units of everything but not edited at all. On all the normal units, remove spells. Edit your custom units to actually build your custom units though.

He wants to disable computers from using the spell, but not players.

remake spells with channel as base

I guess this features a no go then. I would have far too many spells to remake.

Actually I think that your way to do it would be not using a Computer Slot but a neutral slot. Or no slot at all

neutral hostile casts spells for sure, but i dont know about the other neutrals

neutral, really neutral doesn't have an ai, I think.

Well If you use no slot at all and initialize it with a trigger it should disable their ai
