Exposing Lua functions in C++ code

[xtreampb]

I want to create a lua script but expose the functions of this script to my C++ game. I am making the UI in lua and want to do something like this

KeyHit(KEY_P)
{
//do lua function calls
//int result=luaUIBtnPress();
}

 

I would also like to send what button was pressed in my lua UI back to my C++ function, as shown above. Can anyone guide me on how i can do this or a better way to do this. Or should I just use wxWidgets or another UI library?

 

Thanks

Does anyone have any idea?

I have wanted to do the same but from what i saw only a small portion of the lua bindings are exposed in the engine. It would be very helpful for leadwerks to expose its internal c++ lua binding library and the native c one that ships with lua.

I recommend tolua++ for this.

I am a compiling newb how do you compile against the leadwerks built in lua?

[xtreampb]

can you provide a link with more details about "tolua++"

I simply added LuaJit to the build so I could make calls to pop and push values off and onto the stack and effectively move data between Lua and my framework. As Josh doesn't expose any of those functions I had no choice but do that.

 

Using a binding library like tolua++ or LuaBind will give you a real access to your C++ classes if that's what you really need.

Is there a way to add lua.h against the engine.dll?
