I was playing around with the idea of make pistonless automatic street lights in Minecraft. My idea was to use a BUD switch to see if a grass block had grown or died.
I know that if grass is underwater during night it dies, but I dont know if it grows back during the day if it's still underwater.
I would also appreciate it if you had any suggestions for non piston BUD switches, the ones I have been trying to use are not ideal because they send out pulses.
