How can I cast the type of a variable with an exported class? Such as this:
GameManager.ts:
export class GameManager {}
Player.ts:
private _manager: GameManager;
when i use a /// <reference path="GameManager.ts" />, i get an error saying GameManager is out of scope or something like that. How does this work exactly?
There are several cases here, depending on where the export class GameManager {} line is:
Option 1: You're using "external" modules (i.e. you have any export declarations at top-level).
In this case, you should remove the reference tag and instead write:
import Manager = module("GameManager"); // N.B. this is the filename, not the class name
...
private _manager: Manager.GameManager;
Option 2: You're using "internal" modules (i.e. your export class is inside a module block, but not an export module block)
In that case, you should keep your /// <reference... tag and write:
private _manager: MyGame.Manager; // N.B. Assuming here that 'GameManager' lives inside 'module MyGame { ... }'
It might be that you don't actually want the export keyword on your class - if you do that, you don't need to qualify it at all (assuming there's nothing else at top-level being exported).
For an internal module you have to wrap the exported class in a module, so the GameManager.ts file should be:
module Game
{
export class GameManager{}
}
Now you can access the GameManager class through
Game.GameManager
