Hi,
for this you can now use the custom action "iterate" available on the Ecosystem which will let you go through incremental steps.
Check this tweet, it shows a screencast of an fsm using some form of iteration, in your case it should behave the same with the help of "iterate".
then everytime Iterate gives you the next integaer, create an object, and position it where you want, the distance between them can be done with a mathematical relation with the current index which will space even each object.
Bye,
Jean
