Lua:attempt to call method ' XXXX ' (a nil value)

Just touch lua, blind.

Background: The project I took over was followed by someone else doing 90% things to continue, using the Cocos2d-x engine to invoke LUA resources from C + +.

When calling the class method, the error attempt to the call method ' XXXX ' (a nil value), the written format is not a problem, the class object is not a null value, but is not to find the method of this class, decode always reported that the method pointer is empty.

Later consult Gao, just know originally is Tolua generated interface file does not open this method interface. Dizzy Oh ~ ~ ~ In this interface file Add method interface is good. This interface file should be able to be generated automatically, I did not check the Tolua use method.
