Teleports you, or the players specified, to the portal or spawn point of a world. Other than permissions for this command, you can set world-specific and portal-specific teleport permissions too. World and portal enter permissions are also active. The portals are listed, like the world portals command, when the portal is not found.
From the Minecraft Wiki: Every world has a "spawn point" (really, an area) located within a few hundred blocks of the origin, which is at coordinates 0x, 0y, 0z. This point is stored in the level.dat file's SpawnX, SpawnY, SpawnZ attributes (although SpawnY seems to be ignored).
Xenonn. Hello. So we have just started our own server, It has no plugins. We created a flat world, and we wanted to set the world spawn and start building. The problem is /setworldspawn not working. My operators tried, and I tried from console too, just not working. We set, and kill ourselves, and spawn in another coordinate. In this video, I will show you how to set a spawn point in Minecraft. Changing your spawn point will be useful when you die so you don't end up getting lost 2iAWGUm.
