Anyone know if there is a way to convert a string into an object reference? Say, something like:

Code:

"tile" + number.toString()

To get references to objects named 'tile0' through 'tile9' in a for loop, for instance.

Yes, but that's pretty much the worst way of managing your tiles. Just use an array!

You'll need to create the variable in an Object:

Code:

var myOb:OBject = new Object();
myOb["tile1"] = 23;

trace( myOb.tile1 );   // traces "23"
trace( myOb["tile1"] );   // also traces "23"

Buuuuutttt.... that's a technique I only use for very specific reasons, and storing an array of tiles is not one of them. Just using:

Code:

var myArray:Array = new Array();
myArray.push( new Tile() );
myArray.push( new Tile() );

for each ( var tile:Tile in myArray ){
    // dothings with yer tiles.
}

.. is much safer and much faster.

Isaac's advice is good, but just in case you're curious... In the specific case of tiles defined in your SWF's Library, you can do stuff like this:

Code:

var classObject:Class = getDefinitionByName("Tile" + number) as Class;
var myTile:DisplayObject = (new classObject() as DisplayObject);

That assumes your classes for the tile symbols in your library are called "Tile1", "Tile2" etc. and that they have zero-argument constructors.

This is sometimes the neatest way to pull large quantities of stuff out of the Library in a purely programmatic way.

(Disclaimer: Code section above written from memory and not tested!)

Thanks, you guys, a combination of the square bracket syntax and getDefinitionByName() should do. And just for the record, I'm not really doing anything with tiles, it was just as an example. :)

And here I am again :D

I've got a little problem with defining a constant (or generally just a variable) that every class in the project is supposed to access.

But I don't really know how I'd do that. I've tried a C++-esque attempt, by defining the variable in a "Global.as" and then importing it everywhere I need. Sadly, it isn't able to read the variable, so I probably did something wrong.

I've got a little problem with defining a constant (or generally just a variable) that every class in the project is supposed to access.

The approach you seem to be attempting works like this:

* Make your constant a public static field of some class (say "Global") and then access it as "some.package.path.Global.myFieldName".
* As above, but use "import some.package.path.Global" to allow you to use the shorter "Global.myFieldName" to refer to it.

The key word here is static. I'm guessing you didn't declare it as such, and if you don't then you need to instantiate the class (and with it the const) before you can access it. Usually I define consts as static, they tend to be more useful that way and take up less memory.

Also, make sure it's public. Just in case.

Umm, just in case:

Code:

// Declare as:
public static const myConstant:String = "This is my constant";

// Access with:
private var myVar:String = Class.myConstant;
