V2020.1.56.3_ Emitter
Overview
The Beam Emitter is a component that projects an optical (laser) beam used for detecting objects. It is used in conjunction with a Beam Receiver and/or a Beam Reflector.
A Beam Emitter projecting its beam onto a Beam Receiver (left) and a Beam Reflector (right)
Where to find
The Beam Emitter Physical and Logic components can be found under Standard Components > Beam Sensor > Emitter.
It can be accessed from the GameObject menu or the Hierarchy Context menu.
A new GameObject will be created if you do not have a GameObject selected or otherwise, the Beam Emitter will be added to the selected GameObject

Physical Component
Live Data |
|
State | Shows whether the Beam Emitter is currently active and thus whether it will emit a beam |
Redirection Limit Reached | Shows whether the maximum number of redirections have been reached |
Properties |
|
Reach | The maximum distance the beam is allowed to travel |
Origin Offset | Allows the beam to originate from an offset position relative to its GameObject position |
Origin Direction | Allows the beam to be rotated relative to its GameObject rotation |
Max Number of Redirections | The maximum amount of redirections from Beam Reflectors allowed, lowering this value improves performance |
Beam Material | The material used to render this beam. If no material is used, a Gizmo will be drawn instead |
Beam Radius | The radius by which this beam will be drawn with if a material is used |
Use Origin Gizmo | When selected, shows a gizmo for the origin position and the origin direction of the beam |
Origin Gizmo Size | The size of the gizmo shown in Scene View |
Use Beam Gizmo | When selected, draws a gizmo for the beam if no material has been set |
Beam Color | The color the beam gizmo will be drawn in |
Beam Excess Color | The color of the beam excess will be drawn in (after reaching its Max Number of Redirections) |

Logic Component
Properties |
|
Beam Emitter | The Phyisical Beam Emitter component attached to this Logic component |
PLC I/O | In the PLC I/O panel you can see the latest input and output values from the PLC |
PLC settings and Debugging
These settings are general Logic Component settings.
How to use
Assign a Beam Emitter physical component to a GameObject, or create a new one directly from the menu
Select the desired settings under the Properties tab
In order to detect objects passing through the beam, a Beam Receiver must be created
Direct the beam at the Beam Receiver
Objects with a Collider will interrupt the beam, changing the signal value of the Beam Receiver
