Pressure Pad is a Custom Block effect available in the Workshop. When applied, it causes the custom block to emit a green laser from the front side of the block for a maximum range of 16 Blocks, but only when:
a) An avatar stands on the Pressure Pad
b) When another Pressure Pad's beam contacts the Pressure Pad
These green beams have the same effects as a Beam Emitter's: opening Doors; causing Factories to function; activating other Pressure Pads; etc.
This block also has the normal collision of 1m^3 and since the beam emits from the front of the block it must be placed above ground level and therefore must be jumpped up onto to activate with an avatar.
