...And sorting objects.

Let's say I have 5 different objects (Not that it matters, but they're counters), and I want to position them sorted.

Like this.

Obj1 (alt val a = 9)
Obj2 (alt val a = 7)
Obj3 (alt val a = 3)
Obj4 (alt val a = 0)
Obj5 (alt val a = 0)

Someonewannahelp?

Have a lookie here: http://en.wikipedia.org/wiki/Bubble_sort

Certainly one way to do it. Though you may have to use some sort of list object to do it easily since instance selection is the biggest pain on the face of the MMF2.

Or if you have an idea of what range the values will generally be in, you could simply sort them by comparing the value.

Object's Value A = 1
>Mark for position in first row.

Object's Value A = 2
>Mark for position in second row.

There are probably a few ways to do it, but to know the best way it might help to know a little more about your setup.

EDIT: If they're counters, you could try this. Name each one something like "Counter 0" "Counter 1" "Counter 2" etc.

COUNTER CHANGED = 1
>>Start loop number of counters - 1 times.
>>Set COUNTER CHANGED to 0

On loop
+Counter SAVED VALUE (initially 0) is greater than counter loopstep + 1
>>Set SAVED VALUE to loopstep + 1

On loop
+Counter SAVED VALUE is less than counter loopstep + 1
>>Switch values via third counter (Counter 3 = counter 1, counter 1 = counter 2, counter 2 = counter 3)
>>Set SAVED VALUE to loopstep + 1
>>Set COUNTER CHANGED to 1

Then repeat until the loop runs without changing the COUNTER CHANGED value to 1.

No stinking clue if that will work.

You could also perhaps use the high score object?

Does the swap with another object command in tgf/mmf work for instances? .. or is it just for seperate actives?
Maybe if someone figured out how to use it, they could make this bubble sort algorithm for use in the Klik universe.

It might be easier to load all of your counter values into an array (using the Dynamic Array object) and use its "Sort by Values" function.

Is it essential that you physically move the counters or can you just change their values so that they are in the correct order? It would be much simpler to create the counter and set its value than to reposition them.

This is probably not the best way to do it, but it does work...
I made an example file here: http://cid-b1e7ee094271bbda.skydrive.live.com/self.aspx/Public/sorter.mfa

You MUST TICK "Sort" in the List object's properties.
You MUST UNTICK "1-Based Index" in the List object's properties.
This example would only support values up to 999, and only up to 999 objects, but can be easily modified to increase those limits. You could also use the string parser extension, and then it could handle any values you wanted.

● Start of sorting process...
→ List: Set Flag0 to ON
→ Start Loop "Add to List", NObjects("Object") times

● On Loop "Add to List"
● ID Number("Object") = LoopIndex("Add to List")
→ List: Add line "Right$("000"+Str$(Sortable Value( "Object" )), 3)+Right$("000"+Str$(ID Number( "Object" )), 3)"

● List: Flag0 is ON
→ List: Set Flag0 to OFF
→ Start Loop "Sort List", NObjects("Object") times

● On Loop "Sort List"
● ID Number("Object") = Val(Right$(List Line Text$( "List", LoopIndex("Sort List")), 3))
→ Set Rank("Object") to LoopIndex("Sort List")
