MMF interface, faster?

I a little scripting engine setup that Retriever2 helped me make, and the way it currently works with mmf is like this:

function blah(amount,location)
DoCall("blah",amount,location)
end

And then in MMF I check for when "blah" is called and do some actions with the passed values.


Now would it be faster to use the mmf interface to do these actions instead of using DoCall? Or is there no noticeable difference?

Thankers!

whatever's exposed in the interface is going to be much faster than a docall (or any function call that runs through events)

whether this is noticeable or not depends on what you're doing; usually the differences don't show up unless you're doing thousands of calls per frame

Thanks for the reply xyzzy!

also i was bored so i threw this together which shows the kind of differences that show up for many objects

Now that's awesome!

Thanks for that! I'm convinced. I need to move all my code into xlua.

I only have one object that I need to control from xlua, but many instances of it much like in your example. I have my own ID system for the objects, so how could I reference the objects by their id in order to do stuff to them?

Thanks a bunch xyzzy, I almost dropped the idea of moving the code to xlua, but that example proves I need to.

what is the id system based on? spread value?

The ID's are loaded from an array, BUT I suppose I could use spread value though, it wouldn't make a difference.

that ipairs loop is basically equivalent to a spread-value/fastloop engine so you have direct access to the objects already

if you need the ability to, say, get a specific object given a specific id (assuming they're unique), you may want to maintain a reverse lookup table for the object ids

Hmm ok,

How would I make that reverse lookup table? I would need a way to get the lua id for the object based on the value of one of it's alterable variables.

rt = {}
objects = mmf.newObjectClass("Active").objectList

for i,v in ipairs(objects) do
local id = v.values[mmf.ALT_A]
rt[id] = v
end

Oh! Makes sense!

I'll try this when I get a chance!
Thanks alot! You saved me a lot of trouble!
