This would be amazing but probably hard to program... Not sure.Basically a shop sign, but when you purchase it, you purchase a redstone pulse. Possibilities:1. One tick pulseSign: 1st line blank, second line "Power", third line cost sign automatically inserts your name into first line like shop signs. If they left click(or right click) the sign, it send out a 1-tick redstone pulse.2. Custom tickSign: Just like a shop sign! 1st line blank(game auto inserts name), 2nd line is quantity(how many ticks the redstone will stay on), 3rd line cost, 4th line "Power".Use: You could make it so you pay to enter through a door(like to play a game or something), you could make packages for your shops(like pay 1000r for power which powers 4 dispensers that give you a set of diamond armor - bad example because dispensers can run out but you cna do things on the line), I have an awesome idea of how to make a game out of this but I don't want anybody else to use my idea so I want specify anything.Now I'm not sure how difficult this would be. I'd definitely prefer the Custom Tick technique, ad it seems like you could copy a majority of the code from shop signs if you do custom tick. I think this would be an epic add to the game.PS another sign idea(small) is a donate sign. simply a sign that you type "[DONATE]" in the first line, "###" for second line(###=number of rupees), and it auto-inserts your name in the 3rd line. something along those lines. PS I'd always like to have auto insert for signs because if it inserts your name, then that tells you that you did your sign correctly.So what's everybody's opinion!?
