: The spawn/despawn method should work easily because you can choose spawn at
: start true or false (changing the starting state of the door) but all
: "interactive" items that you would want to use without spawning
: or despawning start in the same state. I got it to work with lights but
: not with doors somehow.

Here's what you need to do to solve this:

- Place your two gadgets, such as the Zanzibar gate.

Gate A Settings:
Broadcast Channel: 1

Gate B Settings:
Broadcast Channel: 2

- Place a "Switch: Toggle."

Switch: Toggle Settings:
Broadcast Channel: 1

- Place a "Trigger: On-Enter On" that covers every spawn point in the map. You may place multiples to cover spawn points, but they all need to have the same settings.

Trigger: On-Enter On Settings:
Spawn Channel: 3
Can Despawn: True
Broadcast Channel: 2

- Place a "Timer: Toggle."

Timer: Toggle Settings:
Power Channel: 2
Broadcast Channel: 3
Timer/User Data: 0

- Place a "Timer: Toggle Once."

Timer: Toggle Once Settings:
Power Channel: 1
Broadcast Channel: 2

Now, here's how everything works. When everyone spawns into the game, they will spawn into the "Trigger: On-Enter On." This turns channel 2 on. 2 things happen now:
1. "Timer: Toggle" activates immediately as the timer/user data is 0, so a 0 second delay. It activates channel 3. The "Trigger: On-Enter On" has its Spawn Channel set to 3 and is set to be able to be despawned. So this trigger (and any others with the same settings) all despawn for the rest of the game.
2. Gate B is activated as its broadcast channel is on 2. This leaves Gate B open and Gate A closed.

Now, when the "Switch: Toggle" that controls the gates is activated, 2 things happen:
1. Gate A is opened, as the switch broadcasts on channel 1 and the door was waiting for an activation on channel 1.
2. The "Timer: Toggle Once" is activated, as its power channel was waiting for an activation on channel 1. It sends out a new activation on broadcast channel 2. As its a toggle, it will change the state of channel 2 to the opposite of whatever it was. Channel 2 was previously turned on, so this turns channel 2 off. This results in the closing of Door B, which listens on channel 2.

And then, of course, you're free to continue toggling the switch, which will open/close the doors over and over.

That should do it. As I indicated in another post, I just built this model, and it works.
