[1.12.2] Ticking Entities in Custom Dimension

[Selim_042]

Hello, been a while since I've been here, took quite the break from Forge.  Anyways, I am attempting to create a custom dimension and upon the player entering, the game crashes as it tries to tick the world's entities.

The number of situations where your code isn't necessary numbers precisely zero.

Bump.

[robijnvogel]

Well, it seems like you are quite out of luck in terms of getting help here, it seems.
A friend of mine referred this to me, because he was wondering about some of the terms in your classes; the word "Rift" in particular.

 

You see, I am one of the developers of the 1.12+ port of Dimensional Doors, a mod which is almost completely about "rifts" and their ability to be used as a (teleportation) shortcut to get from point A to point B in no-time, possibly inter-dimensionally.
If you would like to, you could come to our Discord server and state your case and problem there. We'd love it if you'd want to explain the idea behind your mod to us and we hope we can help you.
Also feel free to take a look at our Github.

So your code generates a totally empty dimension, right? At least I didn't see anywhere where you generated blocks. Just checking if that is what you intended. 

 

Also, I'm assuming that your registration code is called properly from somewhere.

 

You didn't create a new WorldType. Don't know if that is a problem, as I usually do a new world type along with my new dimensions. How is the player entering your dimension?

Yep, it is meant to generate an empty dimension.

 

Everything is registered.

 

It isn't a problem as this is now resolved, but now I have an issue with the server and client disagreeing on what dimension the player is in (or that is what I think it is).  Entities from the previous dimension are still being send to the client along with any block updates.

 

Previously (with the above code) the player was entering with an ender pearl, now they are entering with a block right click.
