Hm...well I tried what you just said but it only works the first time and then it won't work after that. If I add a preserve trigger to that one above it'll keep following the observer.
I've tried several different triggers so I'll post what I remembered trying, this is off the top of my head so I might write them incorrectly...
Trigger 1
| Trigger |
| Conditions: |
¤ Bring 1 Attack to dropship area
|
| ¤ "Switch 1" is set |
| Actions: |
¤ Set Player 8 to Enemy
|
¤ Center Location 1 on Observer at Anywhere
|
¤ Order all heros owned by player 1 to attack at location 1
|
¤ Clear Switch 1
|
| ¤ (preserve trigger) |
Trigger 2
| Trigger |
| Conditions: |
| ¤ "switch 1" is cleared |
| Actions: |
¤ Set Player 8 to Ally
|
¤ set switch 1
|
| ¤ (preserve trigger) |
The preserve trigger action is in ( ) b/c I tried them with and without these.
Another variation of this is where I had switch 1 set and then wait 1000 milliseconds and then clear switch 1. But these never worked either. These triggers are off the top of my head so if you need me to clarify or something just ask.
