'Not a function' error with setInterval

I am trying to make a function run 60 times per second. So I've declared setInterval(this.updateAt60, 1/60*1000); in this class' constructor.

This is the function that should be called repeatedly:

LightingScene.prototype.updateAt60 = function(){
   this.controlSubmarine();
   this.submarine.setPosition();
}

Yet, I'm getting the error Uncaught TypeError: this.controlSubmarine is not a function and I can call it everywhere on the code except on there. The order of function declaration is constructor/ controlSubmarine/ updateAt60.

What am I doing wrong?
Thank you in advance.

you are missing the context of `this` – Icepickle May 21 '17 at 13:48
try this one. setInterval(this.updateAt60.bind(this), 1/60*1000); – Dinesh undefined May 21 '17 at 13:49
use `requestAnimationFrame` not `setInterval` – Blindman67 May 21 '17 at 13:51
