[SOLVED] How could we clamp horizontal and vertical movements of a kinematic rigid body?

// update code called every frame

Player.prototype.update = function(dt) {

    if(Player.canPlay == false) return;

    // Position

    var forwardForce = this.entity.forward.clone();

    forwardForce.scale(-0.1);

    this.entity.translateLocal(forwardForce);

    // Rotation

    this.currentRotation.copy(this.entity.getLocalRotation());

    if(this.dx < 0 && this.currentRotation.y <= 0.3)

        this.entity.rotateLocal(0, this.rotationSpeed * dt, 0);

    else if(this.dx > 0 && this.currentRotation.y >= -0.3)

        this.entity.rotateLocal(0, - this.rotationSpeed * dt, 0);

    else

        this.entity.rotateLocal(0, 0, 0);

};

Got It ! Leaving it here for others reference.

     var position = new pc.Vec3().copy(this.entity.getLocalPosition());

    // clamp x position
    position.x = pc.math.clamp(position.x, Min, Max);
    this.entity.setLocalPosition(position);
