how does javascript fixes this issue of threejs or enable3d? (PSEUDO CODE)

@yandeu_ hey I'm using https://t.co/BX4AK23rnW I see that "You can only set the position (and rotation) at any moment if it the body is of type kinematic. " what if I want to teleport my character which reacts to gravity etc? Props for nice project thought....

class MainScene extends Scene3D {

async create() {

for (let step = 0; step < skins.length; step++) {

setInterval(greet, 8000);

            this.man = new ExtendedObject3D()

            this.man.name = 'man'

            this.man.rotateY(Math.PI + 0.1) // a hack

            this.man.add(man)

function greet() {

this.man.position.set(vertibasx, vertibasy, vertibasz)

                // CANNOT ACCESS THIS.MAN.POSITION

}

}

}

}

//this does not work too

class MainScene extends Scene3D {

async create() {

for (let step = 0; step < skins.length; step++) {

        this.man = new ExtendedObject3D()

        this.man.name = 'man'

        this.man.rotateY(Math.PI + 0.1) // a hack

        this.man.add(man)

    }

setInterval(greet, 8000);

function greet() {

this.man.position.set(vertibasx, vertibasy, vertibasz)

                // CANNOT ACCESS THIS.MAN.POSITION

}

}

}

HOW DOES JAVASCRIPT FIXES THIS. ISSUE?.

*****************************************

BIG FIX THAT STILL LEADS TO ERROR DUE THREEJS

class MainScene extends Scene3D {

async create() {

for (let step = 0; step < skins.length; step++) {

this.man = new ExtendedObject3D()

this.man.name = 'man'

this.man.rotateY(Math.PI + 0.1) // a hack

this.man.add(man)

let that = this.man;

}

setInterval(greet, 8000);

function greet() {

that.position.set(vertibasx, vertibasy, vertibasz)

                

//THIS LEADS TO WHITE SCREEN AS GREET HAPPENS, CONSOLE

                //LOGS HERE, BUT POSITION CANNOT BE SET EVERY 8 SECONDS

}

}

}

**********************************

for example ----

class MainScene extends Scene3D {

async create() {

for (let step = 0; step < skins.length; step++) {

        this.man = new ExtendedObject3D()

        this.man.name = 'man'

        this.man.rotateY(Math.PI + 0.1) // a hack

        this.man.add(man)

            window.localStorage.setItem('x', vertibasx);             window.localStorage.setItem('y', vertibasy);             window.localStorage.setItem('z', vertibasz);

        }

        console.log("try", window.localStorage.getItem('x'));

        ///leaves undefined "try"

setInterval(greet, 8000);

function greet() {

this.man.position.set(vertibasx, vertibasy, vertibasz)

                // CANNOT ACCESS THIS.MAN.POSITION

}

}
