Ja ich bin es wieder mit einer neuen SDL technischen Frage.

Ich habe das Problem,dass er ein Rechteck von Rechts nach links blittet. Ich will genau das Umgekehrte.(Von Links nach Rechts)
Hier ist der Code:
Code: Alles auswählen
Animation.h

#ifndef _ANIMATION_
#define _ANIMATION_
class animation{
private:
int vetikal,geschwindigkeit,frame,status;
int startmember,pausemember,pausmember,starmember;
public:
animation();
void start();
void loadimages();
void update();
void autobewegung();
void Move();
void applysurface(int x, int y, SDL_Surface *quelle, SDL_Surface *ziel, SDL_Rect *clip);
void show();
void clips();
int getticks();
