TD - Making spawns attack towers if they can't get to the checkpoint?

[cmilan]

Hey! If anyone can answer this question, please help!

I've always wondered how TD's spawns kill the towers when there is no way they can reach the checkpoint they've been assigned. Can someone tell me how to do that?

(Making the spawns attack the towers ONLY when their's no way to get to the checkpoint?)

Thanks!

Called Struck right?

The way to do is you must create own module of struck.

If the unit strucks and then stops, you can add condition "order comparison" Current Issued Order = STOP.

Or if the unit just walking around, hm... I don't really of this... But Skibi TD by blizzard may help. I remember that a wave that able to attack when the way is blocked by towers.
