Center of mass in body's local space is more useful than the transformed one in some cases, like drawing its position for debug. It's especially useful to get the generated local center of mass when in auto mode (by default). Physics Server BODY_PARAM_CENTER_OF_MASS: Now always returns the local center of mass, instead of setting a local center of mass and getting a transformed one. This causes compatibility breaking, but it makes more sense for the parameter to be consistent between getter and setter. Direct Body State: There are now two properties, because both of them can be useful in different situations. center_of_mass: relative position in global coordinates (same as before) center_of_mass_local: position in local coordinates

<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].

|
|
<description>
|
|
Adds a constant directional force without affecting rotation.
|
|
This is equivalent to [code]add_force(force, Vector3(0,0,0))[/code].

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

<argument index="0" name="impulse" type="Vector3" default="Vector3(0, 0, 0)" />
|
|
<description>
|
|
Applies a single directional impulse without affecting rotation.
|
|
This is equivalent to [code]apply_impulse(Vector3(0, 0, 0), impulse)[/code].

<method name="apply_impulse">

|
|
<argument 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. The position uses the rotation of the global coordinate system, but is centered at the object's origin.

<description>
|
|
Apply a torque impulse (which will be affected by the body mass and shape). This will rotate the body around the vector [code]j[/code] passed as parameter.
