How to loop through objects!

[Keli]

Hi

There is some time since I last used MMFD2 and I have forgotten many things. IN VB I would say:

For i = 0 to 99
object(i).value = rnd(60)
next

Hoe do I do this in MMFD2. I Have 100 objects and I want to place a different random number in each Alterable Value A. I used Duplicate when I created them.

You can just do:
Start of Frame >>> Set 'Value' of 'Object' to random(60)

You can also use fastloops / foreach

Start of Frame >>> Spread ID of Object 0 ; Start loop 'loop' 'Number of 'Object's' times
On loop 'loop' + ID of Object = loopIndex >>> Set 'Value' of 'Object' to random(60)

Or if you have fusion 2.5 you could do foreach:

Start of Frame >>> Foreach of Object
On foreach of Object >>> Set 'Value' of 'Object' to random(60)

Hi

Thanks for your reply. I had already tried your firsth suggestion. But then I always get the same random value in them all. Now I will try to use fast loops.

To translate your VB code exactly into MMF you would do:

Start of Frame
Spread Value 0 through ObjectA

[Trigger Condition]
Set Global Value A: Random(60)

ObjectA(AltValueA=Global ValueA)
Do Some Actions

Edit: Woops. Didn't read the last part of your post. You could create a 'pool' of random numbers and then assign on the first condition above ^, preferably using Bartek's method of ForEach Object and just iterate the once.

Hi

Thanks for your help. I ended up by using clone rather than duplicate. Then I end up with 100 objects. I then used a Group. Then at the start of the frame I set the Alterable Value of A of the group to random(60) and they all get differnet random numbers!

I do not recommend that (since if you update one, all of them have to be deleted and cloned again.)
But if you're happy with it, go ahead ^^

Hi

I was wrong! You are correct Bartek Biszkont! This is just what I needed as you suggestedd. Start of Frame >>> Set 'Value' of 'Object' to random(60)

Sorry

I was looking at a wrong Alternate value
