[1.15.2] How to test if a player is in a dimension

[FossilFind]

In the PlayerTickEvent I want to test if the player is in my custom moon dimension and change the gravity but nothing I have tried has worked. I noticed that some things I tried would work but when I change dimensions either with /forge command or teleport function, the gravity would be the same as the dimension I came from. When I re logged it worked though.

That's an issue with synchronization. Whatever data you are calling is not synced to the client most likely. Read up on sides.

I change a static variable in the LivingEntity to change the gravity so I'm guessing it's only changing on one side. How would I change it on both sides?

Because the server and the client may not be running on the same physical side you need to use networking. Forge does a lot of the work for you, see the official documentation: https://mcforge.readthedocs.io/en/1.15.x/networking/

You need to have the logical server send a message and then have the logical client receive that message and do whatever it needs to as a result (in this case change the gravity).

Also, the functionality that you are describing sounds quite similar to Galacticraft. You might want to to a look at their code for a reference:

I've been messing around with Networking and I have no idea what i'm doing.
