# doomgeneric
|
|
The purpose of doomgeneric is to make porting Doom easier.
|
|
Of course Doom is already portable but with doomgeneric it is possible with just a few functions.
|
|
The limitation is there is no sound!
|
|
|
|
To try it you will need a WAD file (game data). If you don't own the game, shareware version is freely available (doom1.wad).
|
|
|
|
# porting
|
|
Create a file named doomgeneric_yourplatform.c and just implement these functions to suit your platform.
|
|
* DG_Init
|
|
* DG_DrawFrame
|
|
* DG_SleepMs
|
|
* DG_GetTicksMs
|
|
* DG_GetKey
|
|
|
|
|Functions |Description|
|
|
|---------------------|-----------|
|
|
|DG_Init |Initialize your platfrom (create window, framebuffer, etc...).
|
|
|DG_DrawFrame |Frame is ready in DG_ScreenBuffer. Copy it to your platform's screen.
|
|
|DG_SleepMs |Sleep in milliseconds.
|
|
|DG_GetTicksMs |The ticks passed since launch in milliseconds.
|
|
|DG_GetKey |Provide keyboard events.
|
|
|DG_SetWindowTitle |Not required. This is for setting the window title as Doom sets this from WAD file.

# platforms
|
|
I have ported to Windows, X11, and Soso. Just look at (doomgeneric_win.c or doomgeneric_xlib.c).
|
|
|
|
Note that X11 port is not efficient since it generates pixmap by XDrawPoint. It can be further improved by using X11 extensions.
