[UT2K4]Accessing variables from other classes

[eLy]

This has been driving me crazy for a while, and i know it's possibile.
I'm trying to access a global variable from another class, i got the code from http://wiki.beyondunreal.com/wiki/Typecasting
But when i log the variable, it always returns 0.00

here's the variable i want to call.

class MyShockProjectile extends ShockProjectile;

var float MyVar;

function SuperExplosion()
{
             MyVar = 10
             log("test: "$myVar);        // returns 10
	Spawn(class'MyShockCombo');
.....
}

and this is where i want to call it:

class MyShockCombo extends ShockCombo;

var class<actor> ConvertMe;

simulated event PostBeginPlay()
{
          local float x;
          ConvertMe = class'MyShockProjectile';
          x = class<MyShockProjectile>(ConvertMe).Default.MyVar;

......
          
          log(x);      // returns 0.00
}

i just don't get it.
any help is appreciated.
thanks

You're setting an instance variable and reading its default value. Setting a variable of an object naturally doesn't affect the class's defaults.

If you want to set the default value, use "Default.MyVar = 10" -- but you should really know why you want that before you do it, because it defies a whole bunch of OOP concepts.

Well another way to do this is:

class MyShockProjectile extends ShockProjectile;

var float MyVar;

function SuperExplosion()
{
  MyVar = 10
  Spawn(class'MyShockCombo',,Self);
}

class MyShockCombo extends ShockCombo;

var class<actor> ConvertMe;

simulated event PostBeginPlay()
{
  local float x;
  x = MyShockProjectile(Owner).MyVar; // this returns the MyVar set in the object
  x = class'MyShockProjectile'.default.MyVar; // this returns the MyVar default property from class MyShockProjectile
}

thanks solid snake.

hmm,
when i use:
Spawn(class'MyShockCombo',,Self);
i get:
-Error call to spawn type mismatch in parameter 3


Spawn(class'MyShockCombo',Self); works though.

I probably got the syntax wrong. I was pretty sure at the time that the syntax for Spawn in UT2003 was function Spawn(class,name,owner,location, rotation[/i] ...) ... well that's all I can remember of the top of my head.

The Self part in Spawn is just to define who 'owns' the actor.
