adding actions to buttons

[urbaneve]

okay -- i know this is a newbie question.....

but when using actionscript3 (which i need for a flv palyer) i cannot add actions directly to the buttons.

can someone point me in the right direction of how to get actions on my buttons

i have 6 videos that i need to play and when i go to add actions it says"Current selection cannot have actions applied to it"

i an new to AS3 so any help would be great

thanks

cheers

Fortunately you cannot add actions any more directly, which gives headache to people who have to debug it.
Give your button a name and then add an eventlistener:

myButton.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(event:MouseEvent):void
{
//function here
}

okay -- i was going out of my mind thinking i was doing something wrong and couldnt figure out what. i got it to work now. something new to learn - again LOL.

thanks so much for your reply

cheers

So, say you have multiple buttons that lead to different places, would you need a different function for each one? Or is there a way to include parameters using EventListeners?

In other words, is there a way that multiple button objects can call the same function through their Eventlistener, but the function knows which object is calling it?

Inside the function you have
event.currentTarget
which will identify the the object which triggered the event.

I seem to be a bit lost with Actionscript 3.0, I have searched and found how to add actions to a button,

btn1.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(event:MouseEvent):void
{
gotoAndStop(1);
}

but need to add the action to multiple buttons, I tried this but it doesnt woork or look right, any help would be great.

btn1.addEventListener(MouseEvent.CLICK, clickHandler);
btn3.addEventListener(MouseEvent.CLICK, clickHandler);
btn3.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(event:MouseEvent):void
{
btn1.gotoAndStop(1);
btn2.gotoAndStop(5);
btn3.gotoAndStop(10);
}

Thanks

You need to make an if statement or switch function inside the function:

btn1.addEventListener (MouseEvent.CLICK, clickHandler);
btn2.addEventListener (MouseEvent.CLICK, clickHandler);
btn3.addEventListener (MouseEvent.CLICK, clickHandler);
function clickHandler (event:MouseEvent):void
{
    switch (event.currentTarget.name)
    {
        case "btn1" :
            trace ("button 1");
            break;
        case "btn2" :
            trace ("button 2");
            break;
        case "btn3" :
            trace ("button 3");
            break;
    }
}

thanks for the help, so I need to change the trace to the goto action?

[astutelad]

Yes.
Planning out functions using traces is just a good way to test that they've been written properly and will do what you want them to do. :P
