|
<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 [method RigidDynamicBody2D._integrate_forces].

|
<description>
|
|
Adds a constant directional force without affecting rotation that keeps being applied over time until cleared with [code]constant_force = Vector2(0, 0)[/code].
|
|
This is equivalent to using [method 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 [code]constant_force = Vector2(0, 0)[/code].

|
|
<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 name="apply_central_impulse">

<return type="void" />
|

<argument index="0" name="impulse" type="Vector2" />
|
|
<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.
