Javascript Class

Does anyone have a working example of classes in multiple files, running in microStudio in Javascript language. I am not managing to correctly reference classes defined in other files from Main.

I got this error:

Game is not defined, in the file "main" in line 2

and I have the "game" file already defined:

class Game {  
  constructor(){
    this.tiles = [];
    ...
   }
}

this.gameManager = function() { class GameObject { constructor(id, x1, y1, w1, h1) { this.id = id; this.x = x1; // Object x position this.y = y1; // Object y position this.z = 0; // Object z position, to be used to sort the depth this.width = w1; // Object width this.height = h1; // Object height this.name = "test"; // The string name of the object this.instances = []; // Hold instances of this object for grouping }

// Add an instance of this object (called in gameManager.instanceCreate())
instanceCreate(x, y) {
  return (this.instances.push(new GameObject(x, y, this.width, this.height)));
}

// Update the game object
update() {
  
}

}

class GameManager { constructor() { this.objects = []; // Hold a list of game objects }

// Add an object to the object list
objectAdd() {
  var id = this.objects.length;
  this.objects.push(new GameObject(id, 0, 0, 0, 0));
  return (this.objects[id]);
}

// Add an instance of a created object with the ID of id
instanceCreate(id, x, y) {
  let i = this.objects[id].instanceCreate(x, y);
  return (i);
}

}

return new GameManager(); };

You can use this example, sorry for the weird pieces of the blue in pieces, just copy of the the code. I hope this is good. :)

When programming in JavaScript, make sure classes and functions are defined in the global scope using assignments.

// not "function foo() {"
foo = function() {
  // ...
}

// not "class Game {"
Game = class {
  // ...
}
