Rigid Body

The rigid body component adds physics properties, such as mass and velocity, to the entity. The component will simulate physics for the component and set the position and orientation of the entity accordingly.

Properties

  • Mass – The mass of the body.

  • Kinematic – Make the rigid body kinematic instead of dynamic. A dynamic body is affected by external forces such as gravity. Kinematic bodies do not fall or react when hit.

  • Velocity – The initial linear velocity of the body.

  • Angular velocity – The initial angular velocity of the body

  • Linear drag – Resistance of the body to linear movement, between 0 and 1.

  • Angular drag – Resistance of the body to angular movement, between 0 and 1.

If you add a collider component to the entity, the collider is used for rigid body collision, with the center of mass being at the same location as the rigid body.
