seeing if a unit is surrounded

how can i check if a unit is completely surrounded by other units or structures?

replies are greatly appreciated

Count the units that are in X range of the position of the unit

that wouldnt be exactly count as surrounded... but itll come close enough.

I dont know if a unit stops his orders when he's surrounded by units, but when he cant get somewhere he will stop his order after some time.

I've needed this once before, i needed to have a computer player shockwave and or stomp, I used X units in the region as my trigger, and it works pretty well.

Maybe counting ground units only will give better results.

But what region? If you keep moving the region then counting the units in range would be the same but more efficient

Yeah, constantly keeping the region on the unit, and having it count the units in the region is the most effiecient I believe.

Vexorian is right. Moving the region around all the time and getting the units afterwards is slower than just getting units in range. Additionally a rect is squarish, while units in range will get units in a circular area.
