Hey, I tried to give randomclasses to the players but sadly not working -.- . What's wrong?

setup()
{
   self endon ( "disconnect" );
   self endon ( "death" );
   //self takeAllWeapons();
   self.presentroll = RandomInt(5);
   if(self.presentroll == self.lastroll){
//self thread setup();
} else {
self.lastroll = self.presentroll;

           switch(self.presentroll) 
		{
		case 1: 
			self notify("presentroll");
			self thread a();
			break;
		case 2: 
			self notify("presentroll");
			self thread b();
			break;
		case 3:
			self notify("presentroll");
			self thread c();
			break;				
		case 4:
			self notify("presentroll");
			self thread d();
			break;
		case 0:
			self notify("presentroll");
			self thread e();
			break;	
           }
	}
       wait 0.05;
}

Didn't even add the random case to choose.

Depending on what a,b,c,d and e are, this one should be better:

setup()
{   
   switch( randomint( 5 ) )
   {
       case 1:
           self thread a();
       break;

       case 2:
           self thread b();
       break;

       case 3:
           self thread c();
       break;   

       case 4:
           self thread d();
       break;

       case 0:
           self thread e();
       break;   
   }
}
