Change the turning keys from "h l" to "left right"
Just an ease of use suggestion. I found that using h and l is kind of uncomfortable. I think changing them to left and right would be a little better.
How to build on Windows?
I was trying to run makefile and I got an error that says;
gcc -std=c99 -Wall -Wextra -pedantic -Ofast -flto -march=native -lm -lSDL2 main.c -o littlewolf
c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../libmingw32.a(main.o):(.text.startup+0xa0): undefined reference to `WinMain@16'
collect2.exe: error: ld returned 1 exit status
make: *** [Makefile:12: all] Error 1
Any help would be appreciated. Thanks.
Support for Visual Studio 2015
Hi @glouw,
Is it possible to build littlewolf using Visual Studio 2015 or above?
SDL2 vs SDL2-dev
Hi, in the README it sais both SDL2 and SDL2dev should work.
I had libsdl2-2.0-0 installed but it did not work so i installed sdl2-dev and it worked.
Segmentation Fault
I get a seg fault when I try to run it: in color () at main.c:311
Building on Ubuntu
I'm attempting to build and run on Ubuntu Server 19.04 with libsdl2-dev and having problems -
Running make returns errors for various math and SDL2 references.
$ make && ./littlewolf
gcc -std=c99 -Wall -Wextra -pedantic -Ofast -flto -march=native -lm -lSDL2 main.c -o littlewolf

For some reason changing the order of the arguments slightly allows it to compile, but it fails at runtime. SDL_CreateWindow appears to return NULL -
$ gcc -std=c99 -Wall -Wextra -pedantic -Ofast -flto -march=native main.c -o littlewolf -lm -lSDL2 && ./littlewolf
Invalid renderer
Any advice?
Thanks!
Interested in an SDL 1.2 version?
Since this engine is pretty uncomplicated I ported it to Power Mac under SDL 1.2 (now you can compile -DSDL1 to get an SDL 1.2 version, assuming you have SDLMain.m). I can do this as a PR if you're interested; if not, I'll do this in a repository of my own.
[Feature-Request] Textures
It would be great if littlewolf could map textures onto the walls, ceilings and floor.
