- Feb 25, 1991 STK Version 1.1 Released
- --------------------------------------
-
- - Added gr_setvisualpage and gr_setactivepage. These should be used
- instead of the BGI functions, since these set the variables
- gr_visualpage and gr_activepage which are used by other gr functions.
-
- - Added GR_MODE_CLEAR_FAST text writing mode. This mode uses the
- fixed 8x8 character set from ROM and writes directly into screen
- memory. It restricts writing to byte resolution in X direction and it
- works only in those modes supported by the sprite routines, but it
- several times faster than GR_MODE_CLEAR.
-
- - Corrected error with va_start usage in several functions
-
- - The sources can be compiled with Turbo C++ 1.0, too.
-
- - spr_regulate_speed now uses timer interrupt to regulate the speed
- to exactly 18.2 frames per second (provided that the machine is fast
- enough!)
-
- - Documentation divided into two files: STK.DOC gives genereal
- information and STKREF.DOC is a reference to the functions.
-
- - StarMines extended: background stars, several new alien types, hall
- of fame, bug fixes, cheat mode.
-
- - SPRDEMO demonstration program added.
-
- - The functions can be used in the color EGA mode, too, but only
- black and white sprites are supported. If you have a multicolored
- background it is not preserved when the sprites moves over it.
-
- - SPR and SPR_HIT functions check the SPRITE arguments and call
- spr_err if they are invalid.
-
- - Some new gr_printf functions added.
-
- - Load/save filenames are now echoed correctly in SPRED.
