"undeclared identifier" definition

[nod77]

As I explained in one of my recent posts, I had to wait for the next build before a fix htw put in for me was out. In the mean time I've been doing my own build. Well, now that I've had to do my own build, I'm really having fun learning to make stuff. I'd like my clip plane to be adjusted based on the zone population. I found where someone had done it in this post; http://www.macroquest2.com/phpBB3/viewtopic.php?f=31&t=17851

I'm running into trouble when I try to compile it. I'm getting the error, "MQ2AutoClip.cpp(62): error C2065: 'PCcount' : undeclared identifier".

The problem starts right here;

         if (GetSpawnType(pSpawn)==PC) {
            PCcount++;
            }

My question; Is it not properly declared inside this file or is it that it used to be declared in one of the core Macroquest files that makes up say, MQ2Main and has been changed to something else?

Thanks for your time in advance,

No, that's just an error by the author. That variable is not used anywhere except in OnDrawHUD(), so you should just add the declaration and initialize it to zero.

PLUGIN_API VOID OnDrawHUD(VOID) 
{    
  static int N=0;    
  int PCcount = 0;
  if (gGameState==GAMESTATE_INGAME && ++N>SKIP_REDRAW) {
       N = 0;
      // rest of code

htw
