Im modding the game teeworlds, and i have an error like field ‘m_Core’ has incomplete type ‘CCharacterCore’ in character.h, all files who use gamecore.h have like this error.

My gamecore.h is almost the same but I just changed the Init method to

void Init(CWorldCore *pWorld, CCollision *pCollision, CGameContext *pGameServer);

and then all the errors appeared.

I try to write

class CCharacterCore;

in character.h but encountered an error field ‘m_Core’ has incomplete type ‘CCharacterCore’.
