RigidBodyComponent(system, entity) 

Create a new RigidBodyComponent instance.

Parameters

system	RigidBodyComponentSystem	The ComponentSystem that created this component.
entity	Entity	The entity this component is attached to.

numberangularDamping 

Controls the rate at which a body loses angular velocity over time.

Vec3angularFactor 

Scaling factor for angular movement of the body in each axis. Only valid for rigid bodies of type BODYTYPE_DYNAMIC. Defaults to 1 in all axes (body can freely rotate).

Vec3angularVelocity 

Defines the rotational speed of the body around each world axis.

numberfriction 

The friction value used when contacts occur between two bodies. A higher value indicates more friction. Should be set in the range 0 to 1. Defaults to 0.5.

numbergroup 

The collision group this body belongs to. Combine the group and the mask to prevent bodies colliding with each other. Defaults to 1.

numberlinearDamping 

Controls the rate at which a body loses linear velocity over time. Defaults to 0.

Vec3linearFactor 

Scaling factor for linear movement of the body in each axis. Only valid for rigid bodies of type BODYTYPE_DYNAMIC. Defaults to 1 in all axes (body can freely move).

Vec3linearVelocity 

Defines the speed of the body in a given direction.

numbermask 

The collision mask sets which groups this body collides with. It is a bitfield of 16 bits, the first 8 bits are reserved for engine use. Defaults to 65535.

numbermass 

The mass of the body. This is only relevant for BODYTYPE_DYNAMIC bodies, other types have infinite mass. Defaults to 1.

numberrestitution 

Influences the amount of energy lost when two rigid bodies collide. The calculation multiplies the restitution values for both colliding bodies. A multiplied value of 0 means that all energy is lost in the collision while a value of 1 means that no energy is lost. Should be set in the range 0 to 1. Defaults to 0.

numberrollingFriction 

Sets a torsional friction orthogonal to the contact point. Defaults to 0.

stringtype 

The rigid body type determines how the body is simulated. Can be:

• BODYTYPE_STATIC: infinite mass and cannot move.
• BODYTYPE_DYNAMIC: simulated according to applied forces.
• BODYTYPE_KINEMATIC: infinite mass and does not respond to forces (can only be moved by setting the position and rotation of component's Entity).

Defaults to BODYTYPE_STATIC.

applyForce(x, [y], [z], [px], [py], [pz]) 

You can either specify the force (and optional relative point) via 3D-vector or numbers.

// Apply an approximation of gravity at the body's center
this.entity.rigidbody.applyForce(0, -10, 0);

// Apply an approximation of gravity at 1 unit down the world Z from the center of the body
this.entity.rigidbody.applyForce(0, -10, 0, 0, 0, 1);

// Apply a force at the body's center
// Calculate a force vector pointing in the world space direction of the entity
const force = this.entity.forward.clone().mulScalar(100);

// Apply the force
this.entity.rigidbody.applyForce(force);

// Apply a force at some relative offset from the body's center
// Calculate a force vector pointing in the world space direction of the entity
const force = this.entity.forward.clone().mulScalar(100);

// Calculate the world space relative offset
const relativePos = new pc.Vec3();
const childEntity = this.entity.findByName('Engine');
relativePos.sub2(childEntity.getPosition(), this.entity.getPosition());

// Apply the force
this.entity.rigidbody.applyForce(force, relativePos);

Parameters

const impulse = new pc.Vec3(0, 10, 0);
entity.rigidbody.applyImpulse(impulse);

// Apply an impulse along the world-space positive y-axis at 1 unit down the positive
// z-axis of the entity's local-space.
