That looks like a variation of what I said, it's not working?
You shouldn't need the "Turret has target" conditions, as it's in an event triggered by "on shoot", so there is only one turret picked. But that shouldn't keep it from working.
Hmm, I just converted the turret demo to something similar, and the Family isn't picking right. I set it to pick the enemies directly and it worked. I don't use families often, maybe I did something wrong.
Here I went ahead and saved my test capx:
It's the demo for turrets that come with Construct, converted to use families, and multicolored bullets.
But as you can see in Events 16 and 17, the family (disabled) version doesn't work.
