I basically am using dispensers with mob eggs and a commandblock with a player radius so when a player enters within a certain range the dispenser activates. I would like both a way if possible to make the contents of the dispenser infinite but also add a cooldown on how often the dispenser can fire. I'm thinking the best way to do it would be make it so the dispenser only refills after a certain time limit which serves the same purpose as a cooldown. http://dev.bukkit.org/bukkit-plugins/dispenserrefill/ Is a plugin that did this but the plugin isn't updated and only the refill aspect of it works. The version I would need this on would be 1.7.10 and I would be happy to donate to someone for their time if they could make this work. Yes I am aware that the cooldown could be done with redstone however the amount of dispensers I will be using is pretty large scale and it would take a long time to set them all up with redstone. Any help is greatly appreciated!
