方法说明

void add_constant_central_force ( force: Vector3 = Vector3(0, 0, 0) )

Adds a constant directional force without affecting rotation that keeps being applied over time until cleared with constant_force = Vector3(0, 0, 0).

This is equivalent to using add_constant_force at the body's center of mass.

void add_constant_force ( force: Vector3, position: Vector3 = Vector3(0, 0, 0) )

Adds a constant positioned force to the body that keeps being applied over time until cleared with constant_force = Vector3(0, 0, 0).

position is the offset from the body origin in global coordinates.

void add_constant_torque ( torque: Vector3 )

Adds a constant rotational force without affecting position that keeps being applied over time until cleared with constant_torque = Vector3(0, 0, 0).

void apply_central_force ( force: Vector3 = Vector3(0, 0, 0) )

Applies a directional force without affecting rotation. A force is time dependent and meant to be applied every physics update.

This is equivalent to using apply_force at the body's center of mass.

void apply_central_impulse ( impulse: Vector3 = Vector3(0, 0, 0) )

Applies a directional impulse without affecting rotation.

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 (use the "_force" functions otherwise).

This is equivalent to using apply_impulse at the body's center of mass.

void apply_force ( force: Vector3, position: Vector3 = Vector3(0, 0, 0) )

Applies a positioned force to the body. A force is time dependent and meant to be applied every physics update.

position is the offset from the body origin in global coordinates.

void apply_impulse ( impulse: Vector3, position: Vector3 = Vector3(0, 0, 0) )

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 (use the "_force" functions otherwise).

position is the offset from the body origin in global coordinates.

void apply_torque ( torque: Vector3 )

Applies a rotational force without affecting position. A force is time dependent and meant to be applied every physics update.

Note: inverse_inertia is required for this to work. To have inverse_inertia, an active CollisionShape3D must be a child of the node, or you can manually set inverse_inertia.

void apply_torque_impulse ( impulse: Vector3 )

Applies a rotational impulse to the body without affecting the position.

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 (use the "_force" functions otherwise).

Note: inverse_inertia is required for this to work. To have inverse_inertia, an active CollisionShape3D must be a child of the node, or you can manually set inverse_inertia.
