I dont know about the global trigger and what you mean with the switch you explain, but for example:

Block (Scenario 12)

Trigger crate/switch/area/anything (12)

When I stomp on the crate the block should be gone and another crate spawns again (if its not an area). Then if I stomp that crate the block should return.

Or there should be two trigger area's that turn it on/off (for all players in multiplayer).
