[SOLVED] Can't call function from window.onmessage

Help & Support
1

Hi there,
I am actually working on a project where i got to send data from web page to playcanvas iframe.
Actually, i can send data from web page and receive it on playcanvas iframe.
But, in my receive function, i can’t call a function of my script … I think i juste forgot a stupid thing but i don’t see what :smile:

That’s my code :

GameController.prototype.update = function(dt) {
    window.onmessage = function(e) {
        var dataReceive = e.data;
        console.log(dataReceive);
        this.startGame(dataReceive);
    };
};

GameController.prototype.startGame = function(scenario) {
    console.log("Start");
};

And i got this error : Uncaught TypeError: this.startGame is not a function
at window.onmessage (__game-scripts.js:1:25781)

edit : i can see in console my data (line 4)

Anyone can help me ?
Thanks !

You need to bind the function to the scope of the scriptType. ie

    window.onmessage = function(e) {
        var dataReceive = e.data;
        console.log(dataReceive);
        this.startGame(dataReceive);
    }.bind(this);
