EasySpawn is a simple plugin, providing three commands; /spawn, /setspawn and /bed. These will set the spawn location for that world only. So, you can set different spawn locations for different worlds.

Usage

/spawn

Teleports player to spawn.

/setspawn

Sets spawn location.

/bed

Teleports player to their bed

Permissions

/spawn

easyspawn.spawn

by default this works for non-opped players

/setspawn

easyspawn.setspawn

/bed

easyspawn.bed

Permission is given to everyone by default
