Re: Call a lua function and pass a C++ Class object

Weird.  I just tried calling the function with no return type (instead of an int) and it worked.

I changed
int ret = luabind::call_function<int>(luaVM, "UpdateActor", actor);
into
luabind::call_function<void>(luaVM, "UpdateActor", actor);

So how do I get this going with a return value?

Cheers

I'm getting an exception in the proxy_function_caller->Ret operator code (on line 157 of call_function.hpp of luabind-0.8.1).  The exception description is "luabind::cast_failed at memory location 0x0017ebd0."

It looks like it's trying to check the return type of the function that I'm trying to call.  Because the function is declared in Lua script, and not explicitly declared with a luabind def statement, it doesn't know the full function signature.

(It's also entirely possible that I'm barking up the totally wrong tree).

Cheers
Beric

It works fine for me, can you provide more information about what kind 
of error you're getting?
