[1.12.2] Get ID of World object


Recommended Posts

If I have a variable of type World.class how would I get the ID of it? As far as I understand the dimension ID is not stored in the world object. 
What I need to check is if the dimension is the overworld or a custom dimension I have created.
For example if I was to use onBlockActivated how would I get the ID of the world passed though as a parameter?

I don't optimize my code before it works.

Thanks for the quick response! I'm not too familiar with lambda expressions and I like to know what I'm doing with my code. I've read though a few explanations and from what I can tell this is a Comparator Lambda, however, I still don't understand how it's used as I've never worked with them. If it's not too much ask, could you give an explanation and or usage example?

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.
