actually Tristan, you’re right, it’s a property, not a parameter.
and therefore the post has been edited
but besides from that, I’ve been passing on parame…. erhm, properties to objects like in the example above in lots and lots of files without getting into any trouble.

please let me know if you get into any kind of problem using the code example above.
thanks

When you say “parameter,” do you really mean “property”?

At any rate, doesn’t adding a property to an object without using “var” generate an error in AS 3?

you can only add those type of parameters to MovieClips. neither buttons nor Sprites will accept parameters. you can extend the Sprite class to accept parameters though

Assigning the desired parameter to the item itself seems to be very clever. (e.g. blueBox._color = 0×0000FF; …)

This won’t work with buttons. I think there has to be a movieclip around the button and you will have to use event bubbling (?) to catch the CLICK event on the movieclip.

Any other ideas?

var boxes:Array = [blueBox, redBox, yellowBox, blackBox, whiteBox];
var colors:Array = ["0x0000FF", "0xFF0000", "0xFFFF00", "0x000000", "0xFFFFFF"];

for (var i:Number = 0; i boxes[i].addEventListener(MouseEvent.CLICK, changeColor);
}
function changeColor(e:MouseEvent):void{
Tweener.addTween(this.bigBox, {color:colors[boxes.indexOf(e.currentTarget)], time:1, transition:”linear”});
}

//——–
//i think this is the best way if there are more than three boxes and colors

hi Mat.

glad you could use it – the bigBox is a movieclip from the library… alternatively you could just place a movieclip on stage and instancename it bigBox.

easy as pie :O)

Thanks for the help, been looking every where for this answer. Ony one question I don’t undersatnd where you get “bigBox” from.
//
Tweener.addTween(this.bigBox, {_color:e.target._color, time:1, transition:”linear”});
}

Regards
