[Closed] Custom "noise" controller

Hello everybody,

I would like to do a script controller that do the following :

Random change of value – stay still for a random time – change value again, during another ramdom time(not in 1frame) – stay still again, etc…

Here’s a graph :

Does any one have a clue about the math there for a script controller ? Or at least a direction to point me to ?

I can do the “interface” part quite easily (I want to apply it via another script to a list controller on a very large number of object – each of them having different random values)
But I’m quite lost on what would a formula looks like.

I would rather avoid creating random keys on a keyable controller, as I’m afraid this would be 1- too complex for my capacities 2- quite hard to manage on large number of objects.

thanks for your help !

PS : If something like that already exist, I would be very happy to know about it !
