How do I make unit ignore targets behind solid objects (RTS)

I'm starting with C2 RTS example and it's driving me crazy. I can't get friendly units to ignore targets that are behind solid objects.

I fixed both units not to shoot at each other while behind the walls but once the target has been seen (acquired) they are again shooting through walls.

I did manage to stop units from going over each other with a code from forum but I haven't found anything on this problem.

If anyone can help that would be great.

My capx file:

I've looked into the capx briefly and from what I could make out, the units are firing because they have LOS on the enemy (or vice-versa the friendly) even though that's not the their _current_ target.

I've screen cap'd a modification

What I did was:

-get rid of the Foreach in the Tank1Turret (I was wondering if this was necessary?)

-I picked Enemy1Base by querying the Tank1Turret.Turret,TargetUID.

-Then query if Tank1Turret has LOS on that particular TargetUID.

I test it and seemed to work. capx

(Note that I only modified the friendly turrets, not the enemy.

Yes this worked out perfectly! I never would have thought of Tank1Turret.Turret.TargetUID, great solution.

Thank you, I was going crazy with this
