Backends

The OHRRPGCE uses several different backends for graphics and music.

[edit] gfx

gfx backends provide the graphics and user-input. The graphics backend is always the first named, for example, ohrrpgce-wip-gfx-music.zip

name	status	description	fullscreen	smoothing
gfx_fb	stable	Freebasic graphics. This backend is stable, and is used as the default	Windows:Yes Linux:Maybe	Optional
gfx_sdl	experimental	Simple DirectMedia Layer (SDL) graphics. Works, but has some issues.	Yes	No
gfx_alleg	little development	Allegro backend.	Yes	No
gfx_smooth2x	merged	Obsolete experimental backend with smoothing. This functionality was merged into gfx_fb as an optional feature, so no separate backend exists anymore	Windows:Yes Linux:Maybe	Yes

music backends provide the music and sound effects. The music backend is always the second named, for example, ohrrpgce-wip-gfx-music.zip

name	status	description	advanced MIDI looping
music_native	Windows:stable Linux:experimental	Audiere and Native windows midi. On Linux, this backend uses timidity for MIDI	Windows:Yes Linux:No
music_sdl	stable	SDL backend. This is the default on both Windows and Linux	No
music_allegro	obsolete	Allegro backend. Unmaintained; no longer works. Only worked together with gfx_alleg	No
music_native2	experimental	Alternate (windows-only?) implementation of music_native.	Yes
music_silence	diagnostic	Does not play any music or sound at all. Useful for checking whether or not a bug is related to music.	No

name	status	description
-debug	diagnostic	Any nightly build with -debug in the filename has been compiled with -g which adds debugging symbols for use with the GNU Debugger
-exx	diagnostic	Any nightly build with -exx in the filename has been compiled with -exx which adds extra error checking for out-of-bounds array access and null pointer dereferencing.
