C++/C in Love2D?

Will it be possible to run C++/C(more preferably C++) with Love2D ? If so then how?

You can use C via LuaJIT's FFI lib, or use C++ if you make a library yourself and build it to a .so/dll/dylib file.

Ah ok, C is good too. Though I have another question, how can I call a lua function from C ? like call love.graphics.setColor from C, how will I be able to do it ?
Edit:
I tried this:
Code: Select all
ffi = require "ffi"
ffi.cdef[[ #include <stdio.h>
int main()
{
printf("Hi");
}
]]
But it resulted in this error:
o.O

Apparently you don't include things in the FFI. By googling I found out that this is how you should be able to use printf:
Code: Select all
local ffi = require "ffi"
ffi.cdef[[
int printf(const char *fmt, ...);
]]
ffi.C.printf("Hi\n")
link explains something (not much actually) about the FFI.

Why would you want this? At least for me, the big advantage of Löve is that you get to code in Lua. There are plenty of great C/C++ game frameworks out there.

Lua is great, but sometimes a C library does exactly what you want and it'd be a pity not to use it, or you may need pretty intensive math which is much faster in C. It has its uses. You don't use only C with the FFI, but you can easily use it along Lua.

+1. Functions like "love.graphics.setColor" is already written in C++ in LÖVE sources to be used from Lua. You want something like installing VirtualBox in Windows to install Linux with its own VirtualBox again.
If you talking about calling Lua functions from C/C++ in general then you should read about embedding Lua in PIL. It's not very complicated.
