I'm having a problem with including headers:

    
// Npc.h


#include "mission.h"


class Npc : public Person
{

Mission *currMission;

  
      
// Mission.h


#include "npc.h"

class Mission
{
   public:
	
   Npc *told,  //npc that told the npc to do the mission

       *involved; //npc doing the mission

So, basically each header needs the other and that seems to be giving me problems. If Npc.h includes mission.h, mission.h doesn't know what the class Npc is.

A CRPG in development... Need help? Well, go FAQ yourself. [edited by - Nazrix on December 23, 2002 4:39:40 PM]

You have circular include problems.

Use forward declarations. I''m not sure how you choose which one goes where though, hopefully someone will clarify.

E.g. in mission.h you can put:

class Npc;

before everything and not include the "npc.h" file explicitly.

Oh and watch the public members
