Instead of using waits, use the death count timer system. If you wanted to play the music and wait for 60 seconds, then try this trigger.
| Trigger |
| Conditions: |
| ¤ Current Player has suffered exactly 0 deaths of Ursadon. |
| Actions: |
¤ Set Deaths for Current Player: Set to 720
|
¤ Play WAV
|
| ¤ Preserve Trigger |
| Trigger |
| Conditions: |
| ¤ Current Player has suffered at least 1 deaths of Ursadon. |
| Actions: |
¤ Set Deaths for Current Player: Subtract 1 for Ursadon
|
| ¤ Preserve Trigger |
Remember that you need hypertriggers for this to work. And to explain it a bit, we can use death counts as a timer. With hypertriggers, you can add/subtract them at about 12 per second. I took your 60 seconds and multiplied that by 12 and got the 720. Now that the player hasn't suffered 0 deaths of ursadon anymore, the wav won't keeep repeating itself. The second trigger activates itself and starts subtracting the timer.
