How to make a unit stop constructing?

[SckZ]

Hello!

Here's the thing. I am making a Tower Defense type map.

So here is what I want:

-When a player build a tower outside his region (so anywhere else on the map) I want the unit to stop constructing the tower and the tower to be destroyed.

Problem is, I don't know which condition to use... I'm looking for something like:

if (unit being constructed isn't in a region belonging to the player constructing the building) then actions (cancel order, destroy building)

I could just make the unit being teleported back to its region if it enters a region that doesn't belong to it but I'd like to know if there's a way to make my first idea come true.

Thanks!

Boolean function Unit - Unit In Region, action Unit - Kill

You do not even have to wait for the construction though, just cancel the order right away when a build order is targeted outside.

When a unit is issued an order, check if the order is "build"
If the targeted point is outside Region[(Player Number of (Triggering Player))], then, order the triggering unit to "stop". (immediate order)

Didn't see your post there WaterKnight.

Ah alright thanks guys!

The order is not "build", it's the id of the structure. So checking if it's big (>256^3) should be enough because there are not any other object orders with point target.

For simplicity, go for checking if it's higher than 853000 (just a little higher than 0xD02C0 - The max order id)
