Where is the Touch Sensor in 2.7x? In the Logic editor in Blender 2.7x I can't find the Touch sensor. Where is it? Or how duplicate it's function to detect anything.
The Touch sensor has been removed, but in its place there is a updated Collision sensor.

The M/P button will toggle the Collision sensor only targeting a property or material.
To target anything, just leave the property field blank.
