I wasn't sure what RC was (I thought it was a build specific for other things). . It looks nice! It's quite a lot of code though for someone who's used to not coding , I'll play around with it and see what happens. I'll change around some numbers and see if I can add a fixed light to start with.RC = Release Candidate. Basically it's a beta, but one that could be considered as final for public release if no major bugs are found.
