Physics Body whose position is determined through physics simulation in 3D space.
This is the node that implements full 3D physics. This means that you do not control a RigidBody directly. Instead you can apply forces to it (gravity, impulses, etc.), and the physics simulation will calculate the resulting movement, collision, bouncing, rotating, etc. A RigidBody has 4 behavior [member mode]s: Rigid, Static, Character, and Kinematic. [b]Note:[/b] Don't change a RigidBody's position every frame or very often. Sporadic changes work fine, but physics runs at a different granularity (fixed hz) than usual rendering (process callback) and maybe even in a separate thread, so changing this from a process loop will yield strange behavior. If you need to directly affect the body's state, use [method _integrate_forces], which allows you to directly access the physics state. If you need to override the default physics behavior, you can write a custom force integration. See [member custom_integrator].

Called during physics processing, allowing you to read and safely modify the simulation state for the object. By default, it works in addition to the usual physics behavior, but the [member custom_integrator] property allows you to disable the default behavior and do fully custom force integration for a body.
Adds a constant directional force without affecting rotation. This is equivalent to [code]add_force(force, Vector3(0,0,0))[/code].
Adds a constant force (i.e. acceleration).
Adds a constant rotational force (i.e. a motor) without affecting position.
Applies a directional impulse without affecting rotation. This is equivalent to [code]apply_impulse(Vector3(0,0,0), impulse)[/code].
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.
Applies a torque impulse which will be affected by the body mass and shape. This will rotate the body around the passed in vector.
Return a list of the bodies colliding with this one. By default, number of max contacts reported is at 0, see the [member contacts_reported] property to increase it. Note that the result of this test is not immediate after moving objects. For performance, list of collisions is updated once per frame and before the physics step. Consider using signals instead.
Sets an axis velocity. The velocity in the given vector axis will be set as the given vector length. This is useful for jumping behavior.
- Damps RigidBody's rotational forces.
- RigidBody's rotational velocity.
- Lock the body's rotation in the x-axis.
- Lock the body's rotation in the y-axis.
- Lock the body's rotation in the z-axis.
- Lock the body's movement in the x-axis.
- Lock the body's movement in the x-axis.
- Lock the body's movement in the x-axis.
- RigidBody's bounciness.
- If [code]true[/code], the RigidBody will not calculate forces and will act as a static body while there is no movement. It will wake up when forces are applied through other collisions or when the [code]apply_impulse[/code] method is used.
- If [code]true[/code], the RigidBody will emit signals when it collides with another RigidBody.
- The maximum contacts to report. Bodies can keep a log of the contacts with other bodies, this is enabled by setting the maximum amount of contacts reported to a number greater than 0.
- If [code]true[/code], continuous collision detection is used. Continuous collision detection tries to predict where a moving body will collide, instead of moving it and correcting its movement if it collided. Continuous collision detection is more precise, and misses less impacts by small, fast-moving objects. Not using continuous collision detection is faster to compute, but can miss small, fast-moving objects.
- If [code]true[/code], internal force integration will be disabled (like gravity or air friction) for this body. Other than collision response, the body will only move as determined by the [method _integrate_forces] function, if defined.
- The body's friction, from 0 (frictionless) to 1 (max friction).
- This is multiplied by the global 3D gravity setting found in "Project > Project Settings > Physics > 3d" to produce RigidBody's gravity. E.g. a value of 1 will be normal gravity, 2 will apply double gravity, and 0.5 will apply half gravity to this object.
- The body's linear damp. Default value: -1, cannot be less than -1. If this value is different from -1, any linear damp derived from the world or areas will be overridden.
- The body's linear velocity. Can be used sporadically, but [b]DON'T SET THIS IN EVERY FRAME[/b], because physics may run in another thread and runs at a different granularity. Use [method _integrate_forces] as your process loop for precise control of the body state.
- The body's mass.
- The body mode from the MODE_* enum. Modes include: MODE_STATIC, MODE_KINEMATIC, MODE_RIGID, and MODE_CHARACTER.
- If [code]true[/code], the body is sleeping and will not calculate forces until woken up by a collision or the [code]apply_impulse[/code] method.
- The body's weight based on its mass and the global 3D gravity. Global values are set in "Project > Project Settings > Physics > 3d".
Emitted when a body enters into contact with this one. Contact monitor and contacts reported must be enabled for this to work.
Emitted when a body shape exits contact with this one. Contact monitor and contacts reported must be enabled for this to work.
Emitted when a body enters into contact with this one. Contact monitor and contacts reported must be enabled for this to work. This signal not only receives the body that collided with this one, but also its [RID] (body_id), the shape index from the colliding body (body_shape), and the shape index from this body (local_shape) the other body collided with.
Emitted when a body shape exits contact with this one. Contact monitor and contacts reported must be enabled for this to work. This signal not only receives the body that stopped colliding with this one, but also its [RID] (body_id), the shape index from the colliding body (body_shape), and the shape index from this body (local_shape) the other body stopped colliding with.
Emitted when the body changes its sleeping state. Either by sleeping or waking up.
Rigid body mode. This is the "natural" state of a rigid body. It is affected by forces, and can move, rotate, and be affected by user code.
Static mode. The body behaves like a [StaticBody], and can only move by user code.
Character body mode. This behaves like a rigid body, but can not rotate.
Kinematic body mode. The body behaves like a [KinematicBody], and can only move by user code.
