RE: Cleaning up specific lua scripts

["Ricky Haggett" <ricky@...>]

Hey Enrico,

How would I go about loading the level script into a table?

I support both compiled and uncompiled lua, so I load my levels with:

error = luaL_loadbuffer(lua, buffer, length, filename);
lua_pcall (lua, 0, 0, 0);

.. if they're compiled or:

error = luaL_dostring(lua, scriptString);

if they're uncompiled...

Also, if I used setfenv to change the environment, aren't I just moving the
problem? If I then have to add global functions to this same table, how will
I differentiate them from the level functions when I need to clean up?

I am thinking maybe my solution is going to be (shallow) copying _G before
loading a level, then comparing the copy with _G after the level load. Any
objects which don't exist in the copy, but do exist in _G should be the
level-specific ones
Cheers,

Ricky

You could load the level into a table, use setfenv to have level 
functions see this table as 'global', and add true global functions to 
the table when you load a level.
