Question

String in constructor call

I have a variable currentGame which points to a blank Object. A random game is chosen from a pool of many games. I want to then call the right constructor based on the game that was chosen, for example if game1 is chosen, I want my constructor to say currentGame = new game1(); if game 2 was chosen it should be currentGame = new game2();

Each game takes no arguments in the constructor. I was wondering if it is possible to incorporate a string into the constructor call. If it's not I'll just have to make a very large switch statement... but it's always good to know if there's an easier way =]

Thanks
Pem

If it includes it, it will increase the file size, correct? So, when it compiles it only checks actual uses of the class, not strings - because it doesn't know to include those. That'd be my guess.

I found the mistake that was causing the game not to work, it works fine now with the code you mentioned. Thank you all for your help!

Lol. Good to know someone else finds it odd to have to do that. It'd be nice
to have some kind of preprocessor statement to force the compiler to include
classes.

Ah yes, I remember that. I had to do that in order to have a dynamic chosice for the easing in a Tween: http://groups.google.com/group/macromedia.flash.actionscript/browse_thread/thread/4e490b22af91600d/c1118efa06688630?lnk=st&q=author%3ANSurveyor&rnum=1#c1118efa06688630

Perhaps something like:

var str = 'game1';
var f = eval(str);
currentGame = new f();

When I use that code, it doesn't work. The debugger says that currentGame is undefined after currentGame = new f(); is executed. Are you sure this should work?

Amazingly that would work if you could type the var currentGame:
var str = 'game1';
var f = eval(str);
var currentGame:game1 = new f();
But obviously you can't. And you can't use:
var currentGame:f

An option to solve this is to use a class 'GameEngine' that listens to custom events 'game1', 'game2'. Don't know if that's feasible within your app.
