NPC Variables

[kotsumu]

I have some questions about temporary NPC variables.

Lets say I use .@r to store a variable in a NPC would that variable exist only within that NPC?

Now lets say, I have something like...

main {
.@r = 0;
call somefunc;
}
somefunc() {
 .@r = 2;
}

will .@r exist within 2 namespaces? namely main and somefunc or just the npc's namespace?

Also,

Is there any problems with nested switches? Anything to watch out for?

switch(select("1","2","3")) {
 case 1:
   switch(select("2","3")) {
  case 1:
	 ....
  case 2:
	 .....
   }
  case 2:
 switch(selec...
 ....

  ......
}

If it can help

-    script    var    -1,{

   function inside_func { // own namespace
       // .@b: 0
       set .@c, 5;
   } // <- clean .@c

   OnInit:
       set .@a, 5;
       end; // <- clean .@a


   OnEvent: // Custom event
       // .@a: 0
       set .@b, 3;
       inside_func();
       // .@c: 0
       // .@b: 3
       goto OnTest;

   OnTest: // goto keep variables
       // .@b: 3
       set .@c, 8;
       callsub OnTest2;
       // .@b: 3
       // .@c: 8
       // .@d: 0
       end; // clean .@b, .@c

   OnTest2:
       // .@b: 0
       // .@c: 0
       set .@d, 5;
       return; // <- clean .@d

}

.@var are limited to their namespaces and not copy to their inside function/callsub.

But you can modify them in a function using getarg():

-    script    var    -1,{

   function double {
       set getarg(0), getarg(0) * 2;
   }

   OnInit:
       set .@b, 10;
       double(.@;
       // .@b: 20
}

No problem with switch in switch.

You can even do function in function without problem
