How to use properly class with 'this'

Questions

Hi,

I wrote all my class like this example, everything works good.

import * as THREE from "https://threejs.org/build/three.module.js";

class Enemy {
    constructor(sce) {
        this.mesh = new THREE.Object3D();
        let geometry = new THREE.BoxGeometry(50, 50, 50);
        let mat = new THREE.MeshPhongMaterial({
            color: params.color_enemy,
        });
        let enemy = new THREE.Mesh(geometry, mat);
        this.mesh.add(enemy)
        sce.add(this.mesh)
        }
    }
}

export default Enemy;

My problem is that i use ‘this.mesh’ to access my entity, so when i would like modify the position
i must do this :

let enemy = new Enemy(scene)
enemy.mesh.position.set((0,1,2)

What i would like to do is to access directly my entity like this :
enemy.position.set((0,1,2)

For that i must refer “this” to the object itself in my class but i don’t know how…

Could you show me the good syntax ?

Thanks.

In this case you have to derive your class from Object3D. For syntax details, I suggest you have a look how Group is implemented:
