Solved can not get SpawnLocation

I can not get the SpawnLocation of world... HELP

World world = null;
world = this.getServer().getWorld("world");
world.setSpawnLocation(0, 100, 0);
p.teleport(new Location (world,
world
.getSpawnLocation() <-- Error: NullPointerException
.getX(),
world
.getSpawnLocation()
.getY(),
world
.getSpawnLocation()
.getZ()));

 

Safe the location in a variable and set the spawnlocation after this. then use the variable instead of getSpawnLocation(); you should do this anyway to keep your code clean of not needed calls. if you still get a nullpointer exception on this variable, i cant imagine what your server is doing xD
what i think what is happening is, your world is new loaded, but no player is on it, so no chunk is load, so maybe also no location is load, so every method which returns a location will return null. Maybe the list of all locations is setUp with the first chunkgeneration. that's the only thing i could imagine

 

I have the feeling that i#m totally doing the wrong stuff^^

World world = null;
world = this.getServer().getWorld("world");
int x = 0;
int y = 100;
int z = 0;
Location loc = new Location(world, x,y,z);
world.setSpawnLocation(x,y,z); <- NullPointer
p.teleport(new Location (world,
world
.getSpawnLocation()
.getX(),
world
.getSpawnLocation()
.getY(),
world
.getSpawnLocation()
.getZ()));

if i missunderstand you, please correct my code^^

Just use this:

Code:java

 
World world = null;
 
if (Bukkit.getWorld("world") != null) {
    world = Bukkit.getWorld("world");
 
    world.setSpawnLocation(0, 100, 0);
    p.teleport(world.getSpawnLocation());
}

The only thing I could imagine why you're getting a NullPointerException thrown, is because you dont have a World called "world". Because if you'd do, it would not throw an exception. That is the reason why I've added a Null-Check.

 

That seems good but my world Bukkit.getWorld("world") seems to be null...
Because there is no teleport

 

spacemoehre then you don't have a world called "world"....

 

but i have ^^ whats going on???
ok. if i dont have a world called 'world'. how can i create on?
Or has anybody an example??

 

spacemoehre are you sure you have a world named that? Paste startup log please.

spacemoehre the world loaded is "world2", " world" is not loaded and thus is null.

 

how can i load world in the beginn? i want to port my player from world2 to world. i think it is something with the onEnable method...

 

spacemoehre you will first need to load the world, see createWorld method of server, or multiworld plugin.

 

ok...

so that was the problem. i had no worldcreator...
Solved
