Body Nodes

Drop-in replacements for Godot's body nodes that expose Rapier-only settings in the inspector. Use them exactly like the node they extend.

Node	Extends
RapierRigidBody2D / RapierRigidBody3D	RigidBody2D / RigidBody3D
RapierStaticBody2D / RapierStaticBody3D	StaticBody2D / StaticBody3D
RapierAnimatableBody2D / RapierAnimatableBody3D	AnimatableBody2D / AnimatableBody3D
RapierCharacterBody2D / RapierCharacterBody3D	CharacterBody2D / CharacterBody3D
RapierArea2D / RapierArea3D	Area2D / Area3D
RapierPhysicalBone2D / RapierPhysicalBone3D	PhysicalBone2D / PhysicalBone3D
RapierVehicleBody3D	VehicleBody3D

Properties

Rigid bodies, physical bones and the vehicle body expose all of these. Static, animatable and character bodies and areas expose only body_skin.

Property	Type	Default	What it does
body_skin	float	0	Contact skin thickness. Contacts form at this distance, so bodies rest slightly apart. Hides jitter in stacks.
massless	bool	false	The body has no mass of its own. Required for bodies in a multibody joint chain.
dominance	int	0	−127 to 127. Higher dominance is immovable to lower, as if it had infinite mass.
soft_ccd	float	0	Motion clamp distance for soft continuous collision detection; 0 disables. Cheaper than full CCD.
additional_solver_iterations	int	0	Extra solver iterations for this body and everything it interacts with. Stabilizes one important body without a global cost.

Without the custom nodes

Every property is also reachable on a plain Godot node through the server:

RapierPhysicsServer2D.body_set_extra_param(
    body.get_rid(), RapierPhysicsServer2D.BODY_PARAM_ADDITIONAL_SOLVER_ITERATIONS, 4)

See Physics Server for the constants.
