Is it possible to script power ups to disappear and reappear?

Yes.

Power up 1
On power state: alpha: on, spawn
On power state: alpha: off, despawn

Power up 2
On power state: bravo: on, spawn
On power state: bravo: off, despawn

Power up 3
On power state: charlie: on, spawn
On power state: charlie: off, despawn

Script brain
On match start, power state: bravo: off
On match start, power state: charlie: off
On timer: initial: 13: repeat: 90, power state: alpha: on
On timer: initial: 43: repeat: 90, power state: alpha: off
On timer: initial: 43: repeat: 90, power state: bravo: on
On timer: initial: 73: repeat: 90, power state: bravo: off
On timer: initial: 73: repeat: 90, power state: charlie: on
On timer: initial: 103: repeat: 90, power state: charlie: off

This is arguably the simplest way to achieve this, though you could use two power channels, toggle commands, and multi conditions instead. Be sure to remove the default respawn and despawn traits from the power ups for this to work properly.

 

I just remembered, you'll likely want to add 13 seconds to the initial delay of each of the timers to account for the intro sequence and sync the timers with the in-game clock. I'll edit the times in my post.

 

Anything is possible if you believe.

 

*clicks heels together* I believe that rotation can work as is!

I wonder if the power ups fire the On Despawned condition when picked up (like grenades do). Could spawn a teleporter when someone grabs one. Yes, you can have your camo... On the other side of the map.

 

Power ups do technically despawn upon pickup, yes. I like using that to create lights which are only active when a power up spawns and then become inactive when they are picked up. But, you could use that with teleporters too.

 

I was just wondering if lights could be turned off or despawned! Someone was asking about or requesting alarm sounds and I didn't know if using lights instead would work.

 

But srsly, scripting is cray-cray. Unless you want to rotate things, then it sucks ****.
