Hi 👋 i have a issue with getting world from config (line 67), always i want to teleport player to location it sends me Name cannot be null to console. On line 29 i'm using same thing but there is just another file, the setup for both of files are same.
I don't understand why world didn't work but x/y/z/pitch/yaw (lines 68 - 72) works. I tried many variants but after 30 minutes i don't have nerves.

It's probably just wrong path.

#

Is the error on the line with Bukkit.getWorld?

67

#

Can you send the code?

fervent swallow Oct 31, 2021, 2:28 PM

#

Sorry i didn't send screenshot 😂

true forge Oct 31, 2021, 2:29 PM

#

and the config too

#

that's a little bit odd

fervent swallow Oct 31, 2021, 2:32 PM

#

yea ik

true forge Oct 31, 2021, 2:33 PM

#

i think you just need to test it over and over again, play with your code

fervent swallow Oct 31, 2021, 2:34 PM

#

I tested everything

#

or maybe nearly everything

true forge Oct 31, 2021, 2:34 PM

#

and also consider to improve your code design, it's kinda hard to detect issue with your current code

#

and also you can just set location on the config.

#

Location is ConfigurationSerializable

#

FileConfiguration#setLocation(path, location)
FileConfiguration#getLocation(path)

rn it's just draft 😄

#

Ok, so i now know where is problem but how to solve it?

If i "hardcode" path to code it works fine, but when i add"something."+ event +".something" it didn't work.

#

Can problem be in getString()?

true forge Oct 31, 2021, 3:05 PM

#

No way the method FileConfiguration#getString is the problem here.

#

You mean if you do "something.test.something" works and if "something." + event + ".something" doesn't work?

#

There you go then, you found the problem.

#

Show me where you use the getEventLocation method that leads to the error.

fervent swallow Oct 31, 2021, 3:10 PM

#

At /event join command

true forge Oct 31, 2021, 3:10 PM

#

okay, show the getCurrentEvent method

fervent swallow Oct 31, 2021, 3:13 PM

#

It just returning currentevent - string

#

That string is set if some event is started

#

so if I use /event start <event> it also set currentevent

true forge Oct 31, 2021, 3:14 PM

#

uppercases letter matters here

#

that's probably why

fervent swallow Oct 31, 2021, 3:17 PM

#

That is also what i checked but i don't understand why in this case it didn't work only on world, everything else works fine.

#

In this case it works:

#

But if there is String from method it returns null.

#

This is full error message in console:

That's mean your getCurrentEvent is returning null right?

fervent swallow Oct 31, 2021, 11:01 PM

#

Nope, what i dont understand is why only eventw cant get world from config

#

But others like eventx, eventz..... get double without any problem

fervent swallow But others like `eventx, eventz.....` get double without any problem

Ah I don't know then, perhaps try the FileConfiguration#setLocation and FileConfiguration#getLocation
