Which object is best suited to count through a list that has only 2 possible numbers.
I need it to tell me how many time the number 0 is present and how many times 255 is present for each update of the list

Im looking through the zl family of objects but getting quite confused

All help greatly appreciated

Although if I place this into my patch how come the bottom number box doesn’t update when i run my program (start game)?

The list updates but not the bottom number box.

I’m probably missing something simple….

Connect the output of your jit.spill to "my" small contribution, or insert a t b l between your huge message and jit.spill (the b connected to the message, the l to the prepend set). Or…
BTW, you can use the message’s rightmost input instead of using set.

some alternatives using zl or the jit.3m that you already had in place.
