I guess you are right JC, maybe I will just do a simple "dofile" and
worry with performance after. But knowing that it has some way around to
increase performance in a easy way is very important. I had already
faced problems that were easier to start allover again than to optimize
in the way things were implemented.
You're analyzing this way too hard --- this is much easier than you think!
When you load a Lua script it turns into a compiled chunk. Then you run
A script like this:
...turns into a chunk which, *when run*, will add a function foo() to
the Lua VM. This function will remain there until the VM is destroyed
(or more Lua code changes it).
One a function is in the VM, you can easily and efficiently look it up
and run it at any time.
So all you need to do is to structure your AI code so that all the
scripts get loaded once, on startup, and then all you need to do every
GrayFace, I do not get it... do you mean one script with a table where
every script would register its own function?
Almost. The Lua VM will keep track of functions for you (all globals are
stored in a table called _G). So you don't actually need to go to any
extra effort to do so yourself.
