Solved Plugin Interference. Need help.

ISSUE: My plugin is messing around with Multi-verse Core, it's not teleporting the players to their spawns, but sometimes it is teleporting them.

Any help?

 

@VinexAx789
Are you sure the world is loaded? Have you ever been to the location you are teleporting the player to? Have you created a ticket on the Bukkit Dev page?

 

@Zombie_Striker The issue isn't his plugin trust me on that others have seemed to have the problem in the past but haven't stated a fix as I've seen. Also in fact the world is loaded.

Anything, I kinda need to fix this ASAP, thanks.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Bump

 

This error tends to appear a lot when using the teleport method while using the Multiverse Core plugin. What I'd suggest is to just not use it, but there is a line that might be yours:

 

Alright it's just a little odd that I've used the same setup for 3 other games and they work perfectly fine.
I am in fact loading the values in the onEnable.
@CodePlaysMinecraft

 

There are two scenarios:

-A) plugin is null.
-B)maplobby and attackerspawn are both null/ worlds that have not been loaded.

Do a null check on both plugin and those locations to see which one is null.

 

@Zombie_Striker Alright thanks

 

Pass the main class to the other classes using their contructor, then the main class can be used as plugin.

 

@Betagear So almost like an instance but it would be Main.getPlugin()?

 

@VinexAx789 No, just Main.

 

@Betagear I'm already doing that though. In every class or just the ones I need because I did it to the ones I need.

@Zombie_Striker I did some null checking as you said and I gathered this.

Now it does look like the worlds are null but the location Lobby isn't, but how can this be? I did the same thing to everything else how I did Lobby.

SOLVED I did some research and went on Multiverse Core's wiki and look at some code tried to add soft-depend: ['Multiverse-Core'] to the plugin.yml and it worked it still does after 5 times of trying to make sure.

Thanks for the help everyone.
