Notes
- The Player Above sensor detects players in a 5×10-tile area above the sensor, which is outlined while placing it. In multiplayer, it will not send another signal if a player enters the detection zone while another player is already in it.
- Due to this, it is a viable and multiplayer-friendly alternative to Pressure Plate powered automatic doors.
- It will not trigger if placed while the player is inside the detection area. Instead, it will trigger upon leaving the detection zone.
- The Player Above sensor cannot normally activate Teleporters, however, that can be bypassed using a Logic Gate: Use an AND or an OR gate with one off lamp, connect the sensor to its lamp, then wire the output to the teleporter network.
- The Water Sensor will also activate when in contact with Shimmer.
- Rain can not trigger Water Sensors.
History
- Desktop 1.4.2: Dead players and Hardcore ghosts will no longer trigger Player Above sensors.
