Class: RigidBodyUtil

Defined in: packages/physics/utils/RigidBodyUtil.ts:8

Provides a set of methods related to AMMO rigid bodies

Constructors

Constructor

new RigidBodyUtil(): RigidBodyUtil

Returns

RigidBodyUtil

Methods

createRigidBody()

static createRigidBody(object3D, shape, mass, position?, rotation?): btRigidBody

Defined in: packages/physics/utils/RigidBodyUtil.ts:18

Creates an Ammo rigid body.

Parameters

object3D

Object3D

The 3D object.

shape

btCollisionShape

The collision shape.

mass

number

The mass of the collision body.

position?

Vector3

Optional parameter, the position of the rigid body; defaults to the 3D object's localPosition.

rotation?

Vector3 | Quaternion

Optional parameter, the rotation of the rigid body; defaults to the 3D object's localRotation.

Returns

btRigidBody

The newly created Ammo.btRigidBody object.

updateTransform()

static updateTransform(bodyRb, position, rotation, clearFV?): void

Defined in: packages/physics/utils/RigidBodyUtil.ts:46

Updates the position and rotation of the rigid body. This function applies the new position and rotation to the rigid body.

Parameters

bodyRb

btRigidBody

The rigid body object.

position

Vector3

The new position of the rigid body, expressed as a Vector3.

rotation

Vector3 | Quaternion

The new rotation of the rigid body, optional; can be a Vector3 representing Euler angles (automatically converted to a quaternion); defaults to a zero quaternion.

clearFV?

boolean

Whether to clear forces and velocities, optional; defaults to false.

Returns

void
