How can I use the IPHYSICS JavaScript class for physics simulations?

Here's a reference and example usage for the IPHYSICS class, which handles physics simulations in your project.

Documentation and demo: https://didisoftwares.ddns.net/20/index.html

The physics class is defined in the following script:

https://didisoftwares.ddns.net/20/js/physics.js

Usage example:

JAVASCRIPTCopied
import IPHYSICS from "https://didisoftwares.ddns.net/20/js/physics.js"

const physics = new IPHYSICS();

await physics.create().then(() => {
  //YOUR CODE
});

// on update function
function onUpdate(){
  var delta = clock.getDelta();
  physics.update(delta);
}

An example of creating physics objects:

JAVASCRIPTCopied
// create rigid body
const mass = 2;
physics.createObj(mesh, 'geometry', 'obj', null, mass);

// create soft body
physics.createObj(mesh2, 'geometry', 'obj', null, mass, null, { soft: true, pressure: 1 });

The parameters for the createObj method are as follows:

JAVASCRIPTCopied
createObj(
        obj,
        type,     // box - cylinder - sphere - cone - capsule // hull - shape - triangle - geometry
        model,    // obj - tile - wall
        tam,      // vector3 size or null
        mass,     // 0 = non-movable
        contactS, // extra contact size {x, y, z} or null
        extra     // { soft: false, pressure: 1.0, margin: 0.5, ignoreCentroid: false, } or undefined
    )

Remember to create the ground with zero mass so that objects fall onto it. Without the ground, objects might not be visible as they fall out of the scene.
