I want to configure a teleporter so that when I put 300 gold in a switch the teleporter works and deactivates until someone else and does the manipulation again
If you can hook the teleporter up to the switch to Enable it, then point the teleporter to itself to Disable on Enter (or On Teleported ?), that may work.
It also has Activate/Deactivate Link to Target.
I wonder which would be better to use though Activate/Deactivate or Enable/Disable ??
