sdl doom quick tutorial

requires:

SDL
Framebuffer driver
properly set environment vars

Download sdldoom and the wad from http://www.libsdl.org/projects/doom/

wget http://www.libsdl.org/projects/doom/src/sdldoom-1.10.tar.gz
tar -xvf sdldoom-1.10.tar.gz
cd sdldoom-1-10
wget http://www.libsdl.org/projects/doom/data/doom1.wad.gz
tar -xvf doom1.wad.gz
./autogen.sh
./configure
make -j5

copy the doom file to /usr/bin on your didj/lx copy the wad file to a folder on your didj/lx browse to the folder where you put the wad file run doom:

doom

as it stands the buttons don't do anything (dpad up/down/left/right and l/r shoulder move stuff around in the menus but thats it)

fix this by editing doomdef.h

change 2 lines to look like the following:

#define KEY_ESCAPE 109 // 'home button'
#define KEY_ENTER 97 // 'a button'

recompile.

now we can get into the game, yay but we still can't shoot stuff :( boo

make a blank text file called doomconfig save it in the same folder as your doom wad on the lx

run doom, using the following on the command line:

doom -config doomconfig

load a new game, run around and pick up something (not sure if this is entirely necessary), go to the menu and save the game, doomconfig should now be populated

Edit doomconfig, change these 2 lines to the following:

key_fire		98
key_use			112

this will give you 'fire' on the B button and 'use' on the pause key

Other buttons either don't work or don't work as expected if you try and change them via doomconfig, doomdef.h or m_misc.c (defaults get defined here if the config file isn't found), not sure why its behaving like this.

Sound sort of works, looks like it gets the samplerate wrong when doom/sdl opens it :/
