Hello, Has anybody found a way to wrap this?. I mean, you first have to do a lot of push_TYPE things and then call lua_call, and I would like to create a wrapper for example CallLuaFunction(fucntion name, ...), but this do not works because you have to call push for every type. Any Help? Thanks in advance, HexDump.

I have no idea how lua works but something like this maybe

void lua_push(lua_stack* stack, int i) { stack->pushint(i); }void lua_push(lua_stack* stack, float f) { stack->pushfloat(f); }int lua_function0(function name){	lua_call(name);}template <typename type1>int lua_function1(function name, lua_stack* stack, type1 arg1){	lua_push(stack, arg1);	lua_call(name);}template <typename type1, typename type2>int lua_function2(function name, lua_stack* stack, type1 arg1, type2 arg2){	lua_push(stack, arg1);	lua_push(stack, arg2);	lua_call(name);}

There is a section on this in the Lua Reference Manual. Section 3.14 deals with calling Lua functions from C, and includes an example.

I know how to call a Lua func from C. This is not my question. What I wanted is a way to do this calls in a generic way from my wrapper. Anyway I found it. Thanks a lot for the answers.

Thanks in advance,
HexDump.
