README

        
For testing and scripting I used Linuxes (Debian, Arch), and MSYS/MINGW in Windows. Looking forward for Android too (WIP).

launch with LuaJIT.org for example `luajit maze.lua`

| script | description |

|--------|-------------|

| maze.lua | 2d with input and asset loader |

| opengl.lua | 3d |

| app.lua | basic |

https://luajit.org/ext_ffi.html The FFI library allows calling external C functions and using C data structures from pure Lua code.

```

Using SDL from luajit's built-in ffi module

https://gist.github.com/creationix/1213280/a97d7051decb2f1d3e8844186bbff49b6442700a

-- load the luajit ffi module

local ffi = require "ffi"

-- Parse the C API header

-- It's generated with:

--

--     echo '#include ' > stub.c

--     gcc -I /usr/include/SDL -E stub.c | grep -v '^#' > ffi_SDL.h

--

ffi.cdef(io.open('ffi_SDL.h', 'r'):read('*a'))

-- Load the shared object

local SDL = ffi.load('SDL')

```
