Collision Sensor

See the Python reference of this logic brick in SCA_CollisionSensor.

A Collision Sensor works like a “touch sensor” but can also filter by property or material. Only objects with the property/material with that name will generate a positive pulse upon collision. Leave blank for collision detection with any object.


Soft Bodies

The Collision sensor cannot detect collisions with soft bodies. This is a limitation in Bullet, the physics library used by the Game Engine.

Pulse button

Makes it sensible to other collisions even if it is still in touch with the object that triggered the last positive pulse.

M/P button

Toggles between material and property filtering.
