Voilà, le problème est que mon programme plante simplement quand j'appel la fonction Setup ou Execute dans la fonction Run, même si je met tout le contenu de la fonction en commentaire:
First-chance exception at 0x01245ba0 in Bomberman.exe: 0xC0000005: Access violation reading location 0x00000000.
Invalid parameter passed to C runtime function.
Invalid parameter passed to C runtime function.
The thread 'Win32 Thread' (0x117c) has exited with code 3 (0x3).
The program '[4780] Bomberman.exe: Native' has exited with code 3 (0x3).
quelqu'un peut m'expliquer pourquoi?
Merci d'avance
