A little bit late, but anyway: Artaburu released a new version of his utility library for the Z88dk C compiler. E.g. Mariano the dragon or the recently released Nanako Descend To Hell was written with this library and so it contains a lot of graphics functions, key functions, map functions, etc. You can download it from the official homepage of the CPCRslib.
Here are the changes since my last posting:
cpcrslib with horizontal scrolling capabilities is uploaded. From now, there will be 2 official libraries: one for scrolling and one for static screen. Although the scrolling one can be used to for static screens, because it has been improved for scrolling, when static using it is a slower than the "standard" one. Horizontal scroll example included.
Bug in cpc_WyzPlayer corrected. When saving the player interrupt jump, the code was being corrupted due to a bad definition of the address where the original jump was being saved.
cpc_PrintGphStr0,cpc_PrintGphStr0M1: Optimized code: Smaller and faster, thanks to Kevin Thacker for coding it on Blue Angel 69. cpc_PrintGphStr2X,cpc_PrintGphStrXY2X,cpc_PrintGphStrM12X,cpc_PrintGphStrXY2X: New routines for printing graphical text at double height. Sample 5 modified.
