How do I pick family members once each.

Trying to think of an elegant solution for this. Each frame, I only want to pick one family member (it can be random or sequential, doesn't matter), but I want to pick them all once before I start again fresh. I want this to be as fast as possible. So the simplest way I guess would be to somehow cycle through them, but I'm not aware of a familymember[index] type solution. Or otherwise, set a bool as false, pick one with a false, set it to true until all are true and then refresh. But that sounds slow.

So I'm looking for.....

Every Tick - Pick a random family member that hasn't been picked. Work with that instance.

When all have been picked once, refresh and start again.

I suspect that I'm missing something obvious or built in, but I've been away from C2 for a while and I can't think of anything.

I would cycle through them by using :

For 0 to family.count

where (pick by comparison) family.IID = loopindex

That cycles through them in order of IID, you would have to work something in for randomness.

Using a boolean variable seems like a good solution.

On every tick -> call Function.ProcessOne()

Function ProcessOne()
   Pick Family where isProcessed=false
       Pick random Family instance -> do something with it, set Family.isProcessed=true
   Else
       Pick All -> Family set isProcessed=false
       call Function.ProcessOne()

There is nothing in this code that could affect performance, it should work very fast. Function will be called recursively only once in many ticks.

Thanks, those both work. I'd forgotten that IID actually keeps a sequential list and I believe I'm right in saying that if objects are destroyed or added, it maintains a sequential order, so it was just a case of keeping a global counter and counting up until I hit the count. Fairly simple in the end.
