Concept for custom block replacement

Beam Emitter is a Custom Block effect available in the Workshop. When applied, it causes the custom block to emit a red laser constantly up to a maximum range of 16 Blocks. This range can be cut short if an object is placed within the "line of fire" from the beam. If the beam from a Beam Emitter strikes a Pressure Pad, the Pressure Pad also releases a 16-block beam.

When the red beam that is emitted hits a Factory, the Factory begins to produce Doodads.
