For anyone who enjoyes to make Maps in MInecraft you'll know and understand the troubles the minecraft spawning system is. this device is a simple spawn setter, i am posting it because if you ever had to make one, they are kind of a pain so here you are. just make the world spawn over this platform with /setworldspawn and set the command block to either set the players spawn elseware or just to move them to a more preferable spawn location. enjoy!
