<brief_description>
Direct access object to a physics body in the [PhysicsServer3D].
</brief_description>
<description>
Provides direct access to a physics body in the [PhysicsServer3D], 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 [method RigidDynamicBody3D._integrate_forces].

<methods>
<method name="add_constant_central_force">
<return type="void" />
<param index="0" name="force" type="Vector3" default="Vector3(0, 0, 0)" />
<description>
Adds a constant directional force without affecting rotation that keeps being applied over time until cleared with [code]constant_force = Vector3(0, 0, 0)[/code].
This is equivalent to using [method add_constant_force] at the body's center of mass.
</description>
</method>
<method name="add_constant_force">
<return type="void" />
<param index="0" name="force" type="Vector3" />
<param index="1" name="position" type="Vector3" default="Vector3(0, 0, 0)" />
<description>
Adds a constant positioned force to the body that keeps being applied over time until cleared with [code]constant_force = Vector3(0, 0, 0)[/code].
[code]position[/code] is the offset from the body origin in global coordinates.

</method>
<method name="add_constant_torque">
<return type="void" />
<param index="0" name="torque" type="Vector3" />
<description>

</method>
<method name="apply_central_force">
<return type="void" />
<param index="0" name="force" type="Vector3" default="Vector3(0, 0, 0)" />
<description>
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 [method apply_force] at the body's center of mass.

</method>
<method name="apply_central_impulse">
<return type="void" />
<param index="0" name="impulse" type="Vector3" default="Vector3(0, 0, 0)" />
<description>
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 [method apply_impulse] at the body's center of mass.

<description>
Applies a positioned force to the body. A force is time dependent and meant to be applied every physics update.
[code]position[/code] is the offset from the body origin in global coordinates.

<return type="void" />
<param index="0" name="impulse" type="Vector3" />
<param index="1" name="position" type="Vector3" default="Vector3(0, 0, 0)" />
<description>
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).

</description>
</method>
<method name="apply_torque_impulse">
<return type="void" />
<param index="0" name="impulse" type="Vector3" />
<description>
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).
