Functions | |
void | PA_InfLargeScrollX (u8 screen, u8 bg_select, s32 x) |
Scroll a large infinite scrolling background horizontaly. It must have been initialised with PA_LoadLargeBg. | |
void | PA_InfLargeScrollY (u8 screen, u8 bg_select, s32 y) |
Scroll a large infinite scrolling background vertically. It must have been initialised with PA_LoadLargeBg. | |
void | PA_InfLargeScrollXY (u8 screen, u8 bg_select, s32 x, s32 y) |
Scroll a large infinite scrolling background horizontaly and vertically. It must have been initialised with PA_LoadLargeBg. | |
void | PA_LargeScrollX (u8 screen, u8 bg_select, s32 x) |
Scroll a large background horizontaly. It must have been initialised with PA_LoadLargeBg. This function does not wrap around, but is faster than the InfLargeScroll... | |
void | PA_LargeScrollY (u8 screen, u8 bg_select, s32 y) |
Scroll a large background vertically. It must have been initialised with PA_LoadLargeBg. This function does not wrap around, but is faster than the InfLargeScroll... | |
