collider_type
There are two types of colliders:
- A solid collider represents a geometric shape that can have contact points with other colliders to generate contact forces to prevent objects from penetrating-each-others.
- Sensor colliders on the other end don't generate contacts: they only generate intersection events when one sensor collider and another collider start/stop touching. Sensor colliders are generally used to detect when something enters an area. Note that, for symmetry with non-sensor colliders, sensors do contribute to the mass of a rigid-body they are attached to.
By default a collider is a solid collider. This can be changed to a sensor when constructing the collider, or after its construction:
The sensor status is set with the ColliderBuilder.sensor method, or with the is_sensor property of the collider:
# Set the collider type when the collider is created.
collider = rp.Collider.ball(0.5).sensor(True).build()
# Set the collider type after the collider creation.
collider = world.colliders[collider_handle]
collider.is_sensor = True
