Notes[edit | edit source]

The Player Above sensor detects players in a 5×10-tile area above the sensor. In multiplayer, it will not send another signal if a player enters the detection zone while another player is already in it.
- It will also trigger on the position of dead players until they respawn. This fact may be relevant in situations where the player is likely to be killed near the sensor.
