Pass parameter to button callback

[mtburdon]

Hi there,

 

I'm trying to do something which I think should be rather simple but I don't seem to be able to achieve it.

 

When a button is clicked, I'm trying to pass a parameter to the button callback function, however if I pass anything to the function and console.log it out, it's always the clicked button.

 

Is there a way to pass a parameter other than the button to the button callback?

 

Thanks!

Martin

Hi,

the second parameter is as you wrote the button itself. I dont know if this helps you, but you could give the button for example a name (ie Button.name = variable) and read this again in your function

Hope it helps

Yes, Blackgames is right, something like this:

    function create() {        buttonA = game.add.sprite(100, 100, 'buttonA');        buttonA.variable = "Hi there!"        buttonA.inputEnabled = true;        buttonA.events.onInputDown.add(doSomething, this);    }    function doSomething (item) {        console.log(item.variable);    }

Thanks guys, I managed to sort it with your brilliant help!

 

The code example from Pedro Alpera was particularly helpful.

 

Thanks again all!
