How would I go upon making my "Specific Unit Event - Notices a target in range" event into a "Generic Unit Event - Notices a target in range" ?? Ideas would be helpful.
You can and you can't. I'm guessing the reason you want this is because you want the event to work for a unit that you haven't preplaced (as specific unit events only work with preplaced units). The trick to this is to put the unit in a variable, then use the Trigger - Add Event action. You can pick the specific unit event, and you will now be able to select the variable.
I have a guard at a gate (belonging to computer) and is just on watch. When something comes in range of him, I want him to basically open the door and run. How would I detect that unit? Both units are not pre-placed.
I can't just predict which units come in contact with each other. I need a trigger that will fire when any unit (offensive) comes in range with another any unit (defensive)
Just use regions. Place a region around your guard and then use Event - unit enters region to trigger your guard unit to open the gate and run like hell.
