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();

Most probably because the class definition is not registered in the _global
namespace.

Simple (but bloody strange) solution:

// add these statements somewhere in the script -- they will force the
compiler to load the class definitions
// note: must be fully qualified class paths
game1;
game2;
// etc...

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

should work?

Thanks for the help! I tried out the last suggestion (adding game1; game2; and so on) and this time around, the object is created correctly... but for some reason the game does not run still. But that is most likely an error in some other part of the code, so I'll have to look into that. I didn't quite understand what you meant by "note: must be fully qualified class paths" , maybe that's what I did wrong...
