So instead of using Event Disable, I simply did the same thing, but adjusted a few things.
if (follow==0)
{
y=y+0;
}
else
{
y=Ball.y;
}
Your idea was sort of working. Since this is in Draw Actor though, this will be checked every frame iirc, and thus the A.I is just stuttery instead, but still getting to the ball. Even if you set follow=rand(2), it is still basically impossible. It is not until you set it to follow=rand(1) that the A.I stops being able to get to the ball...but in that case, it just doesn't move. I suppose I can work with the odds more. Make it to where if follow is less than or equal to a number, then the following from above happens, and vice versa for greater than.
