How to use this.entity.translate within a custom class scope

Help & Support
1

Hello, and I hope you guys are having a great day so far. I am currently trying to create a custom class called BasePlatform that moves around the entity attached to the script.

This is because I want to make many different platform types, and I want them to all have this base functionality to extend. However, when I do this I struggle trying to call this.entity.translate(…); within the scope of my BasePlatform class, as the this keyword is different in that scope.

Then to debug and try out different things I discovered that if I try to use this.something to reference the entity that the script is attached to anywhere but within the ScriptName.prototype functions, or as a global variable, it is instead read as undefined.

EX:

var test = this;
function e(){
    test.entity.translate(...); //doesn't work
} 

Platformz.prototype.initialize = function() {
    test.entity.translate(...); //doesn't work
}
function func(){
    this.entity.translate(...); //doesn't work
}
//All of these don't work to my understanding, apologies for any faulty testing

…etc.

My code:

class BasePlatform{
    constructor(stuff, movement, time, rotation, enemy, doesLoop){
        this.movement = movement;
        this.rotation = rotation;
        this.isEnemy = enemy;
        this.timeArray = time;
        this.timer = 0;
        this.currentIndex = 0;
        this.loops = doesLoop;
        this.stuff = stuff;
    }
    updatePlatform(dt){
        if (this.currentIndex >= this.timeArray.length){
            if (this.doesLoop === true) {
                this.currentIndex = 0;
            }
            else{
                return;
            }
        }

        if(dt == 0){
            return;
        }

        this.timer += dt;
        //console.error( this.movement[this.currentIndex].x , (dt * this.timeArray[this.currentIndex]) )
        console.error(this.stuff.entity.name);
        console.error(this.entity.name);
        this.stuff.entity.translate(this.movement[this.currentIndex].x / (dt * this.timeArray[this.currentIndex]), this.movement[this.currentIndex].y / (dt * this.timeArray[this.currentIndex]) , this.movement[this.currentIndex].z / (dt * this.timeArray[this.currentIndex]));

        if(this.timer >= this.timeArray[currentIndex]) {
            this.timer = 0; 
            this.currentIndex++;
         }
    }
}
var newPlatform = new BasePlatform(this, [new pc.Vec3(3, 3, 3), new pc.Vec3(-3, -3, -3)], [3, 1], 0, 0, true);

// initialize code called once per entity
Platformz.prototype.initialize = function() {
    this.entity.translate(1, 0, 0);
    var e = this;
    e.entity.translate(0, -10, 0);
    console.error(this);
};

This results in stating that it cannot call .translate on undefined. What should I do to fix this?

Sorry for the over-complexity, and thank you for your time.
