I'll give this a try later. What's the -1 for in >lua_tointeger()?
Almost all lua_* functions operate with stack. -1 is stack index. Like indexes in lua itself 1 means first value in the stack, 2 means second, ..., -1 means last, -2 means last but one, ... In lua_pop you though specify how many values to pop, not which element to pop. > >Is there a good way to test this when I'm done?
