PhysicsDirectBodyState2D¶
Inherits: Object
Direct access object to a physics body in the PhysicsServer2D.
Description¶
Provides direct access to a physics body in the PhysicsServer2D, allowing safe changes to physics properties. This object is passed via the direct state callback of dynamic bodies, and is intended for changing the direct state of that body. See RigidDynamicBody2D._integrate_forces.

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 collider's object id.
Returns the collider object. This depends on how it was created (will return a scene node if such was used to create it).
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
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 RigidDynamicBody2D.contact_monitor.
Returns the local normal at the contact point.
Returns the local position of the contact point.
Returns the local shape index of the collision.
