Some issues: static int Einschlagsnummer; Is never default initialized. Some code paths return nothing so whatever is in [e]ax gets returned, which may be 1. If Trefferchance is <= 80 and m_Schutzwall > 5, it will return 1 for each iteration up to five. However, you stated that m_Schutzwall is 1 which means it's never decremented to zero since the test is for m_Schutzwall > 1, not m_Schutzwall >= 1. This suggests that the return value is likely what happens to be in [e]ax. now nitpicking: int Zufallstreffer; Zufallstreffer=rand()%99+1; int Trefferchance; Trefferchance=rand()%99+1; Why not initialize the variables in the declaration of them? Why m_Schutzwall=m_Schutzwall-1; instead of --m_Schutzwall;

I added these lines. There is still no effect. Please take a look at the code i postet with a thread i made in questions. I think it has something to do with the way i manage the edit control where directx is supposed to render. It would be really nice if you take a look in my other thread. Thanks a lot.
