V2020.1.56.3_ Receiver


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 or 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



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



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

  1. Assign a Beam Receiver physical component to a GameObject, or create a new one directly from the menu

  2. Create the desired signal events under the Properties tab

  3. In order to detect a beam, a Beam Emitter must also be created

  4. Direct the beam from the Beam Emitter at the Beam Receiver

  5. Objects with a Collider will interrupt the beam, changing the signal value of the Beam Receiver
