Overview
The Color Sensor is a component that can be used to detect colors directly in front of it within a certain range.
A Color Sensor detecting colors of the objects in its field of view.
Where to find
The Color Sensor Physical and Logic components can be found under Standard Components > Color Sensor > Color Sensor.
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 Color Sensor will be added to the selected GameObject.
Feature layout
Physical Component
Live Data | |
State | Shows whether the Color Sensor is currently active and thus whether it will detect colors. |
Output Signal | Shows what color the ColorSensor currently detects. If no color is detected, it will return its Void Color. |
Properties | |
Range | The minimum and maximum detection range for the Color Sensor. A gizmo shows a visual indication of how that will translate in the scene. |
Void Color | The default color that will be returned when no colors are detected. |
On Value Changed | A UnityEvent that is fired as soon as the Output Signal of the Color Sensor changes. Other scripts can subscribe to this event to be notified of the change. |
Fixed Rendering | The function forces the color sensor to detect colors on fixed intervals which will prevent it from possibly missing frames. WARNING: This function is very resource heavy. |

ColorSensor | The Phyisical Color Sensor 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. Look at the Logic Component Documentation for more details.
How to use
Assign a Color Sensor physical component to a GameObject, or create a new one directly from the menu.
Select the desired settings under the Properties tab.
In Play Mode, the color of detected objects will be displayed in the Output Signal field.
