I have an array which produces random numbers and pass this list to another array. How can I select the numbers from the first array, so that only 1 every let's say 5 goes to the second array? Thanks,
The simplest way is to use Decimate 1D Array. You can expand this node so that it creates 5 output arrays. The first output will be every 5th element of the input array, starting with the first.
