I am currently setting up a hardcore spigot 1.15.2 Minecraft server for myself and my friends. Due to popular demand, we want
some kind of way to revive players using nether stars. I am new to using command blocks and was thinking I could achieve this
by making the command block detect a nether star in achest/hopper, detect the player name, then when both requirements are
met execute the command /gamemode survival (player name), finally, the command block should delete the items once the
command is executed. I really have no clue where to start on this and any help, ideas, or changes would be greatly appreciated.
