@ Undead
I'm sorry, I don't understand. Are you saying if the unit is within that 1 range of acquisition?
Edit:
Ohhhhh. If its a ranged unit. You can still attack at whatever their range is I believe, you just have to order the attack.
@Xonok I think he wants the unit to still be able to attack from the bush, just not auto attack from it, they would like the user to decide when to "reveal" oneself.
