Chapter 517: AmmoPhysics

Core Idea

Can be used to include Ammo.js as a Physics engine into three.js apps. The API can be initialized via:

The component automatically imports Ammo.js from a CDN so make sure to use the component with an active Internet connection.

Code Examples

const physics = await AmmoPhysics();

Methods

Method	Description
.addMesh( mesh : Mesh, mass : number, restitution : number )	Adds the given mesh to this physics simulation.
.addScene( scene : Object3D )	Adds the given scene to this physics simulation. Only meshes with a physics object in their Object3D#userData field will be honored. The object can be used to store the ma…
.setMeshPosition( mesh : Mesh, position : Vector3, index : number )	Set the position of the given mesh which is part of the physics simulation. Calling this method will reset the current simulated velocity of the mesh.

Key Takeaways
