Method Descriptions¶
void add_constant_central_force ( Vector2 force=Vector2(0, 0) )
Adds a constant directional force without affecting rotation that keeps being applied over time until cleared with constant_force = Vector2(0, 0).
This is equivalent to using add_constant_force at the body's center of mass.
Adds a constant positioned force to the body that keeps being applied over time until cleared with constant_force = Vector2(0, 0).
position is the offset from the body origin in global coordinates.
void add_constant_torque ( float torque )
Adds a constant rotational force without affecting position that keeps being applied over time until cleared with constant_torque = 0.
void apply_central_force ( Vector2 force=Vector2(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 ( Vector2 impulse )
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.
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.
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 ( float torque )
Applies a rotational force without affecting position. A force is time dependent and meant to be applied every physics update.
void apply_torque_impulse ( float impulse )
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).
Vector2 get_constant_force ( ) const
Returns the body's total constant positional forces applied during each physics update.
See add_constant_force and add_constant_central_force.
float get_constant_torque ( ) const
Returns the body's total constant rotational forces applied during each physics update.
See add_constant_torque.
Returns the collider's RID.

Returns the contact position in the collider.
Returns the collider's shape index.
Returns the linear velocity vector at the collider's contact point.
int get_contact_count ( ) const
