2021.1.1560.3 Contrast Sensor
Overview
The Contrast Sensor will match a detected color to its Base Color and its Background Color and give an output depending on which of the two colors matches most with the detected color.
A Contrast Sensor analysing three cubes for a Base color and a Background color. The Output Signal returns High for the red cube since it corresponds to the Base color, and low for the green and blue cubes since they correspond more to the Background color.
Where to find
The Contrast Sensor Physical and Logic components can be found under Standard Components > Color Sensor > Contrast Sensor > Add Physical Component.
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 Contrast Sensor will be added to the selected GameObject.
