LemonDOOM

Port of doomgeneric to Lemon OS.

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.

Windows

X11 - Ubuntu

X11 - FreeBSD
