If you have more than one object thats duplicated, but you want to link it to a detector thats also been duplicted more than once, how would you pair them so that MMF doesnt get confused?
It basically assigns an ID number to all objects matching the conditions of the event. If you do:
ALWAYS
- Spread 1 in A
The 'ALWAYS' condition selects all objects (since you didn't mention any objects specifically). The spread then enumerates all objects.
However, doing this:
X POS of object > 320
- Spread 1 in A
...will select only the objects whose X position is greater than 320. The spread will then only enumerate those objects. Others are left at whatever value they had before.
So you can also use it to loop through objects that meet certain conditions, and follow those objects even after those conditions no longer run true.
No wait, what are you on about Tyscorp? Why would you run a fastloop to spread a value, when the action already applies to all instances of the object when you run it once?
Tyscorp is confused... why would you loop it? Spread 0 in value A in object, will do it for all the objects... looping will just do that repeatedly, which is stupid.

No, his code makes it spread the value through all available objects, only way faster. You'd have to code more to make sure it works on any new instances of the object too, though... Which means at every condition that makes one.
Maybe I'm having a dense moment and just not seeing this, but how is it faster?
So far as I know, the Always: Spread command will ennumerate every instance of that object within one event. By the time the first frame is drawn, all your objects will be numbered.
You can see this by doing a fastloop, but telling it to run only once, like this:
Start Of Frame
... Run loop 'SPREAD' 1 time
On Loop 'SPREAD'
... Spread 1 in Value A
The loop occurs only once, yet every object is Numbered. This is because MMF is automatically fastlooping through all the objects, it doesn't need to be told.
That said, using fastloop in the above way to trigger a Spread command is better, since it saves on having pointless 'ALWAYS' commands. There's no point spreading the values again if nothing has changed. You just trigger the loop to run once when an object is created or destroyed, and once at the start.
Um, what? You really think using a fastloop, and three extra lines of code, would make it faster? And all that's required to make it work for new objects is to replace start of frame with always.
First of all, it is never nessicary to add an Always + another event... Second of all, that event will fire all the time anyway since there always will be objects with a value lower than the number of objects (Unless there only is one objects ofcource)
Going a little off topic, but since we're discussing 'always', what is the use for 'never'. I genuinly cannot see where i would use it, because it stops an event running? Sorry if i'm being stupid .
As for NEVER, I think it's used to test events. If you have a bug in your game, and you don't know where it is, you can just keep shoving 'never' conditions into various events to stop them working. If the bug goes away, you know the error is being caused by that event.
It's better than deleting events, since you don't lose all your actions. Although personally, I just create a group, deactivate it, and shove the event inside that. I wish you could just tick a box next to event lines to disable them instead of bothering with 'never'.
Sorry about my earlier post Dines, you posted while I was typing my reply. It was actually aimed at DaVince.
And yer doing it wrong DaVince! There's no need for any fastloops, no need for always conditions in conjunction with other conditions, and using fastloops won't make it faster. To spread a value in all instances of an object, even new ones, just use:
...which is the bit I don't get, cos I don't see how it possibly could be faster
191 / 9999 * 7 + 191 * 7

Ever seen that demo with around 1000 stars being put on screen one by one with an "always" loop and a fast loop? The fast loop places them almost immediately where the always event takes around two seconds to do it. That's what I meant with it goes faster.
The reason for that is that Always is creating one star per frame, whereas Fastloop can do hundreds of stars per frame.
The difference with Spread Value is that it already fastloops within the Spread Value function. It'll do this if it's triggered from Always, a Fastloop, or even a single 'Start of Frame' condition.
You can test it by doing a 'Space key is pressed' condition and spreading a value with that. Even though the event triggers once, it'll ennumerate all objects.
