Overview
The Beam Receiver is a component that can detect an optical (laser) beam emitted by a Beam Emitter.
A Beam Emitter projecting its beam onto a Beam Receiver (left) and a Beam Reflector (right).
Where to find
The Beam Receiver Physical and Logic components can be found under Standard Components > Beam Sensor > Receiver.
It can be accessed from the GameObject menu as well as from the Hierarchy Context menu.
A new GameObject will be created if you do not have a GameObject selected. Otherwise, the Beam Receiver will be added to the selected GameObject.

Physical Component
Live Data | |
State | Shows whether the Beam Receiver is currently active and thus whether it will detect a beam. |
Output Signal | Shows whether the Beam Receiver currently detects a beam or not. |
Properties | |
On Signal High | A UnityEvent that is fired as soon as the Output Signal of the Beam Receiver is set to “High”. |
On Signal Low | A UnityEvent that is fired as soon as the Output Signal of the Beam Receiver is set to “Low”. |

How to use
Assign a Beam Receiver physical component to a GameObject, or create a new one directly from the menu.
Create the desired signal events under the Properties tab.
In order to detect a beam, a Beam Emitter must also be created.
Direct the beam from the Beam Emitter at the Beam Receiver.
Objects with a Collider will interrupt the beam, changing the signal value of the Beam Receiver.
