Uncaught TypeError: Cannot read property 'X' of undefined

[robot9706]

Hello! I just wanted to port a really simple XNA 4.0 project to JS and when I try to run it in my browser (Google Chrome) it throws me this error: "Uncaught TypeError: Cannot read property 'X' of undefined". Stack trace:

Microsoft_Xna_Framework_Vector2_op_Addition$lbvec$cmvec$rb Microsoft.Xna.Framework.Vector2.op_Addition[vec,vec]:6
Game1_Update XnaJSILTest,%20Version=1.0.0.0,%20Culture=neutral,%20PublicKeyToken=null.js:149
Game_TimedUpdate XNA4.js:1337
Game_VariableTimeStep XNA4.js:1442
Game_TimeStep XNA4.js:1519
Game_Step

Here's the "Microsoft.Xna.Framework.Vector2.op_Addition[vec,vec]" code:

(function() {
//# sourceURL=jsil://closure/Microsoft.Xna.Framework.Vector2.op_Addition[vec,vec]
"use strict";
function Microsoft_Xna_Framework_Vector2_op_Addition$lbvec$cmvec$rb(lhs, rhs) {
    return new this.$instance(
    +(lhs.X + rhs.X),
    +(lhs.Y + rhs.Y)
    );
    };
        return Microsoft_Xna_Framework_Vector2_op_Addition$lbvec$cmvec$rb;
})

Here's the Xna Project and the converted code if it helps: http://www.mediafire.com/download/awtrsae7aeq1d7g/XnaJsPort.zip

That's most likely caused by some other unimplemented method called earlier on, that then returned undefined. Then when you pass undefined into the addition operator, it fails. Check the log to see what's unimplemented?

I think I found something:

Error: The external method 'Microsoft.Xna.Framework.Vector2 op_Multiply(Microsoft.Xna.Framework.Vector2, System.Single)' of type 'Microsoft.Xna.Framework.Vector2' has not been implemented.

Yeah, that's probably it. Odd, I thought i implemented that. I'll take a look.
