CollisionObserver

The CollisionObserver is a simulation component that observes collisions of a specified 3D object in the simulation environment.

When to use

Use this simulation component when you want to detect and respond to collisions between a specified 3D object and other objects in the simulation environment.

How to use

Add this simulation component from the simulation component library. Define the Object3D which you want to observe for collisions. Define which type of rigid body (e.g. static, dynamic or kinematic object) should be observed.

Parameters

Object3D

This parameter specifies the 3D object that you want to observe for collisions. The rigid body behavior of this 3D object must be either Dynamic, Static or Kinematic.

ObserveStaticObjects

This parameter determines whether static objects should be observed for collisions. If set to true, the CollisionObserver will detect collisions involving static objects.

ObserveKinematicObjects

This parameter determines whether kinematic objects should be observed for collisions. If set to true, the CollisionObserver will detect collisions involving kinematic objects.

ObserveDynamicObjects

This parameter determines whether dynamic objects should be observed for collisions. If set to true, the CollisionObserver will detect collisions involving dynamic objects.

Outputs

Collision

This output indicates whether a collision has been detected. It returns true if a collision has been detected.

Example

In this example, the CollisionObserver is used to observe the red colored gripper of a robot.

If the gripper collides with the environment, the robot should get colorized with the Colorizer simulation component.

The gripper object is of type Kinematic. The environment is defined as Static. In the following picture, the robot collides with a track which leads to the coloring of the robot.

The amount of collisions could be counted with the Counter simulation component.
