Hi! I'm new here so I'm adjusting. I'm currently on mapping... I think I can help you...
First thing first. Create a variable called "PatrolGroup (Unit Group or Unit)" then use this trigger.
Pur first the unit in the PatrolGroup variable
If the patrolling unit is in the map, then:
Events
A unit comes within (100) range of (Your patrolling unit)
Condition
---Nothing Here---
Actions
Unit - Kill (Triggering Unit) --->If only you will just kill the unit
Game - Defeat --->If you want to kick the player from the game.
Else, if the unit will be created in-game, use this:
YOU NEED DUMMY UNIT FOR THIS.
Events
(The time where you want to create the unit)
Conditions
---Nothing Here---
Actions
Unit - Create (Your patrolling unit) at (where you want to put the unit) facing (Default building facing) degrees
Set "PatrolGroup" = (last created unit) ---> if the variable is a Unit
Unit Group - Put (last created unit) on (PatrolGroup) ---> if the variable is a Unit-Group
Unit - Create 1 (Dummy Unit) at a range of (the range of the patrol) with offset 100.00 (or something) from PatrolGroup --> i forgot about this part. I'll check when I get home.
Unit - Order PatrolGroup to Patrol at Position of last created unit (or store the the dummy unit in a variable if you like.)
Then, do this new trigger:
Events
A unit comes within (100) range of (PatrolGroup)
Condition
---Nothing Here---
Actions
Unit - Kill (Triggering Unit) --->If you want to kill the unit
Game - Defeat --->If you want to kick the player from the game.
