Actionscript deep copy function

Here is an recursive function I found that allows you to deep-copy objects (other then MovieClips) in ActionScript. #ctionscript doesn't have this functionality built in yet, so this may prove useful to someone. Credit to the original poster - http://theolagendijk.wordpress.com/2006/09/04/actionscript-object-duplication/.

/// duplicate any given Object (not MCs)
Object.prototype.copy = function()
{

var _t = new this.__proto__.constructor(this) ;
for(var i in this)
{

if(typeof this[i] == “object”)

_t[i] = this[i].copy()

else

_t[i] = this[i];

}
return _t;

};
ASSetPropFlags(Object.prototype,["copy"],1);

This is very useful to me, as copying objects, usually arrays, is something that crops up often, at least for me ;). This way I can be sure that the contents get copied, not just the reference.

This is how it’s used.

var x:Array = new Array(“1″,”2″,”3″,{a:1,b:2});
var y:Array = x.copy();

The class or interface 'uint' could not be loaded. Actionscript 2

If you're trying to migrate your flash project from Actionscript 2 to Actionscript 3, or you're interrating some Actionscript 3 code into your AS2 project, you may encounter this error in numerical calculation functions:


The class or interface 'uint' could not be loaded.

The reason is that the uint (and int) types only became available with AS3. with As2, your stuck with good old Number.

If you're confident that your project is AS3 ready, just change your Publish settings like so:

Note: AS3 requires flash player 9+ selection
