[Fallen Guardian]

Alright, I've managed to get my above script to compile by making it like this:

void main()
{


     object oPC=GetFirstPC();

     object oNPC=GetObjectByTag("dt_comm");

  int nEvent = GetUserDefinedEventNumber();

int bRun=TRUE;

  if( 
        (nEvent == 1002) &&
        GetGlobalBoolean("DT_CHECK1") == FALSE)
        {

        if(GetDistanceBetween(oNPC, oPC) <= 6.0){

    ActionDoCommand(SetCommandable(TRUE, oNPC));

  AssignCommand (oNPC, ActionMoveToObject(oPC, bRun));

  AssignCommand (oNPC, ActionStartConversation(GetFirstPC()));
  
    } 
  }
}

I'll edit this post to tell if it works in-game or not.
