AI does not attack me.

I use some commands to order AI using their spells, such as:

call IssuePointOrder(u, "carrionswarm", x, y)
call IssueImmediatelyOrder(u, "taunt")
call IssueTargetOrder(u, t, "channel")

Everything seems alright, but sometimes they just stand there and do nothing, even attacking me. Do you know why?

What event are you using to pull off the AI commands?

It could be that the spell range and something else are not matching.

Maybe. It works now, thanks for your comment.
