Rigid body component for physics simulation.

Defines a physics body that can be dynamic (affected by forces), kinematic (animated but affecting others), or static (fixed in place). Attach alongside a ColliderComponent to participate in collision detection and response.

Fields

handle: Option<RigidBodyHandle>

Internal handle assigned by the physics engine (managed automatically).

body_type: RigidBodyType

Body type: Dynamic, KinematicPositionBased, KinematicVelocityBased, or Fixed.

translation: [f32; 3]

Initial position in world space.

rotation: [f32; 4]

Initial orientation as quaternion [x, y, z, w].

linvel: [f32; 3]

Linear velocity in world units per second.

angvel: [f32; 3]

Angular velocity in radians per second.

mass: f32

Mass in kilograms (only affects dynamic bodies).

linear_damping: f32

Linear velocity decay rate. 0.0 leaves motion to drag-free space, higher values bleed off translation over time. Default: 0.0.

angular_damping: f32

Angular velocity decay rate. 0.0 spins forever, higher values settle rotation over time. Default: 0.0.

gravity_scale: f32

Per-body multiplier on world gravity. 1.0 is normal, 0.0 floats, negative rises, 2.0 falls twice as hard. Default: 1.0.

locked_axes: LockedAxes

Constraints on which axes can translate or rotate.

ccd_enabled: bool

Enable continuous collision detection. Costs CPU but prevents fast-moving bodies from tunneling through thin geometry. Default: false.

Implementations

impl RigidBodyComponent

pub fn new_dynamic() -> RigidBodyComponent

Creates a dynamic rigid body affected by forces and gravity.

pub fn new_kinematic() -> RigidBodyComponent

Creates a kinematic rigid body driven by setting its translation each frame.

pub fn new_kinematic_velocity() -> RigidBodyComponent

Creates a kinematic rigid body driven by setting its linear velocity. Unlike the position-based kind, it responds to set_linvel, which is what scripts use to move it, and dynamic bodies cannot push it.

pub fn new_static() -> RigidBodyComponent

Creates a static (fixed) rigid body that never moves.

pub fn with_translation(self, x: f32, y: f32, z: f32) -> RigidBodyComponent

Sets the initial translation.

pub fn with_mass(self, mass: f32) -> RigidBodyComponent

Sets the mass in kilograms.

pub fn with_linear_damping(self, damping: f32) -> RigidBodyComponent

Sets the linear damping (translation decay rate).

pub fn with_angular_damping(self, damping: f32) -> RigidBodyComponent

Sets the angular damping (rotation decay rate).

pub fn with_gravity_scale(self, scale: f32) -> RigidBodyComponent

Sets the per-body gravity multiplier.

pub fn with_rotation(self, x: f32, y: f32, z: f32, w: f32) -> RigidBodyComponent

Sets the initial rotation as a quaternion.

pub fn with_ccd(self, enabled: bool) -> RigidBodyComponent

Enables continuous collision detection for this body. Use for fast-moving bodies that would otherwise tunnel through thin geometry (bullets, fast props).
