rigidbody

Since 0.6

Use it in a scene entity's components list as { "type": "rigidbody", … }. The contract writes the fields flat and refuses unknown keys.

Fields

Field	Type	Required	Default	Allowed values	Description
`kind`	`BodyKind`	yes		`static`, `dynamic`, `kinematic`
`mass`	`number`	no
`friction`	`number`	no
`restitution`	`number`	no
`ccd`	`boolean`	no			Continuous collision detection for this body, overriding the scene's physics quality. true makes it a bullet: whenever it moves fast it is swept against every other body, moving ones included, so a thrown ball or a projectile cannot pass through a thin wall or a crate between two ticks. Two bullets are not swept against each other. false keeps it out of the quality's per-body CCD (fast bodies are still swept against static colliders unless the quality's ccd is off). Absent follows meta.physics (medium: on for bodies moving fast enough to tunnel). Only dynamic bodies use it.
`lockAxes`	`LockAxes`	no			World axes this body may not move along or turn about, e.g. { "rotation": ["x", "z"] } for a crate that only turns about Y. Combines with planar. Only dynamic bodies use it.
`planar`	`boolean`	no	`false`		true keeps the body in the XY plane at the Z it spawned at: translation locked on Z and rotation locked about X and Y, so it only slides in X and Y and spins about Z (2D physics on the 3D solver). Adds to lockAxes. Default false. Only dynamic bodies use it.
