Re: [Flashcoders] Object vs *

String, Boolean, Number, int, uint are all Objects...

var a:String = "";
trace(a is Object); //true

var b:uint;
trace(b is Object); //true

I find * useful when I don't want to explicitly type cast:

function a():Object {
return "hi";
}
var b:String = a(); //compile time error

function a():* {
return "hi";
}
var b:String = a(); //this is legal

[Flashcoders] Flash - cross-platform? really?

2008-08-09 Thread Ashim D'Silva 
We've been developing a flash game over the last few weeks, and we're
finding more and more that the flash player on PC and Mac run terrifyingly
differently. In my previous experience, website I've built have run far
better on my Mac than on other PCs, but this time its the opposite. The PC
version runs great, but on Mac, there's a nasty nasty chug. It seems to get
better if I compile it on a Mac. And gets far better if I compile to a Mac
self executable.

We're trying to find out what's causing it, and thinking it may be the
animated sprites, although all they're doing is reassigning bitmapData. All
processing sprite sheets is done at initial setup.

So, is there anything people know about or have experienced?

The WIP is here: http://raws.adc.rmit.edu.au/~s3155488/

Thanks for the help in advance...

Also, mind this:

var a:*;
trace(a);
// undefined

var b:Object;
trace(b);
// null

An Object can't be undefined.

Cheers,
Claus.

If you have functions:

public function getThing():*
{
  return new Bucket();
}

public function getAnotherThing():Object
{
  return new Bucket();
}

then this will compile:

var someVar:Bucket=getThing();  // Ignores type checking

And this won't:

var someVar:Bucket=getAnotherThing();   // Tries to assign Object to
Bucket. Compile-time error.

(while this will - with a cast:

var someVar:Bucket=getAnotherThing() as Bucket;

)
