Passing Parameters in Functions and Event Listeners

[urieljuliatti]

I'd like to know what's the different using global functions and functions with param..

Why using params? When the as3 developer uses it?

Sory about this simple question.. I'm new on AS3

Somebody help me..

What do you mean by "global functions"?

And parameters are used when a function have to act on an unknown object. For example, let's say you have a game in which the player has to catch some items. Every time the player catches an item, this item disappears with a cloud of smoke. To be able to make things disappear easily, you make a function like this:


function removeItem(object:DisplayObject):void {
object.visible = false
var smoke:SmokeCloud = new SmokeCloud()
smoke.x = object.x
smoke.y = object.y
smoke.play()
}

removeItem(coin)

This code will make the item "coin" disappear and an instance of the SmokeCloud class play in the place.

a global function would be "trace" because works from anywhere, you don't need to import it. trace takes also some parmeters.

Good! I'll try to understand doing some exercises here
