Is there a way to detect when a player wants to cast a target-ability but cancels before he even targets something?
For example, let's say a player wanted to cast Flamestrike, hits "F" for the hotkey, but never targets anything and just right-clicks out. Is there a way to detect this? I know if they hit escape, it is detectable, but I want to be able to detect it with both escape and right-clicking out. |
