I've been working on an update behind the scenes for a while that I've just deployed: Logic Gates.
I initially started working on it thinking it would be super simple, but as is often the case, there were some details that made it trickier than it seems at first blush. I implemented all the basic two-input gates ( https://electronicsclub.info/gates.htm
XNORI didn't implement NOT, since a NOR can be used as a NOT gate.
These behave pretty much the way I believe you would expect, however, they do not
behave exactly like digital circuits since there is everything is processed in discrete steps, and there is no propagation delay. So this means that they are processed the way all other behaviors are, but it also means that some circuit types (e.g. S-R Latch) probably won't the same as its electrical counterpart.
I also added a new "Download" button in sprite editor to download your sprites. This has been requested lots of times.
I didn't yet fix any of the new bugs reported, since I've been sidetracked with this update, but I hope to tackle those next.
