Description

Provides direct access to a physics body in the PhysicsServer, allowing safe changes to physics properties. This object is passed via the direct state callback of rigid/character bodies, and is intended for changing the direct state of that body. See RigidBody._integrate_forces.

Getter get_total_gravity()

The total gravity vector being currently applied to this body.

  • float total_linear_damp

Method Descriptions

  • void add_central_force ( Vector3 force )

Adds a constant directional force without affecting rotation.

This is equivalent to add_force(force, Vector3(0,0,0)).

Adds a positioned force to the body. Both the force and the offset from the body origin are in global coordinates.

  • void add_torque ( Vector3 torque )

Adds a constant rotational force without affecting position.

  • void apply_central_impulse ( Vector3 j )

Applies a single directional impulse without affecting rotation.

This is equivalent to apply_impulse(Vector3(0, 0, 0), impulse).

Applies a positioned impulse to the body. An impulse is time-independent! Applying an impulse every frame would result in a framerate-dependent force. For this reason it should only be used when simulating one-time impacts. The position uses the rotation of the global coordinate system, but is centered at the object’s origin.

  • void apply_torque_impulse ( Vector3 j )

Apply a torque impulse (which will be affected by the body mass and shape). This will rotate the body around the vector j passed as parameter.

  • RID get_contact_collider ( int contact_idx ) const

Returns the collider’s RID.

  • int get_contact_collider_id ( int contact_idx ) const

Returns the collider’s object id.

  • Object get_contact_collider_object ( int contact_idx ) const

Returns the collider object.

  • Vector3 get_contact_collider_position ( int contact_idx ) const

Returns the contact position in the collider.

  • int get_contact_collider_shape ( int contact_idx ) const

Returns the collider’s shape index.

  • Vector3 get_contact_collider_velocity_at_position ( int contact_idx ) const

Returns the linear velocity vector at the collider’s contact point.

  • int get_contact_count ( ) const

Returns the number of contacts this body has with other bodies.

Note: By default, this returns 0 unless bodies are configured to monitor contacts. See RigidBody.contact_monitor.

  • float get_contact_impulse ( int contact_idx ) const

Impulse created by the contact. Only implemented for Bullet physics.

  • Vector3 get_contact_local_normal ( int contact_idx ) const

Returns the local normal at the contact point.

  • Vector3 get_contact_local_position ( int contact_idx ) const

Returns the local position of the contact point.

  • int get_contact_local_shape ( int contact_idx ) const

Returns the local shape index of the collision.

Returns the current state of the space, useful for queries.

  • void integrate_forces ( )

Calls the built-in force integration code.
