[1.15.2] [Solved] Stuck while loading custom dimension

[Budschie]

So, I recently tried to add a dimension. But when I try to teleport to it with a command,

it will get stuck, without any log output. I also have a feeling that I didin't register my dimension stuff properly.

I recently found out that the world is already loaded (an ambient cave noise played), but the rendering thread is most probably stuck.

My guess is that you just used the standard Minecraft Teleporter assuming that it works for all dimensions. Note: you can't do that as the teleporter handles logic specifically for teleporting to and from the nether. My knowledge on the matter however is a bit outdated. However, you can verify this by debugging your code at the method you have selected and watch it return null.

[Budschie]

Well, now I teleport with this code:

			ServerWorld worldnew = DeepnetherMain.server.getWorld(cmdContext.getArgument("dim", DimensionType.class));
						
			player.teleport(worldnew, player.getPosX(), player.getPosY(), player.getPosZ(), player.rotationYaw, player.rotationPitch);

but I will still get stuck.

Why don't you just use forge setdimension ingame?

[Budschie]

Thanks. But the problem I've mentioned above still persists.

I'm pretty sure I've done something wrong while registering my dimension. If I try to teleport to my dimension on the client, it "works", but gets stuck. On the server, my dimension isn't even shown in the autocomplete of the /forge setdimension command.

Try usingDeferedRegister, it'll most likely fix all your problems.

Thanks. I successfully switched to DeferredRegister, but the problem still persists...

Here's an example of how I did it in my mod.

@Novârch

Thats a bit long. You can do this shorter:

public static final RegistryObject<ModDimension> D4C_DIMENSION = DIMENSIONS.register("d4c_dimension", D4CDimensionType::new);

 

[Ugdhar]

Side note: you can use DimensionManager.registerOrGetDimension instead of checking for the dimensiontype by name being null.

 

Have you tried setting breakpoints, stepping through the code, and seeing where the code execution gets stuck?

[Budschie]

@Ugdhar Yes.

Where does it get stuck/what is it doing?

[Budschie]

@Ugdhar It gets stuck after the dimension is initialized and after the chunk generator is created. Some network stuff can also be processed and recieved on the main thread.

[Budschie]

By the way, java doesn't "crash" like it is usually the case (The message "javaw.exe" doesn't react anymore doesn't appear)

[Budschie]

And I have to terminate the process manually, I can't exit the application with the red X button.

If you keep stepping through it, do you get to an endless loop or something? I mean, doing that should show you exactly where in the code it's getting stuck. I'm guessing something is null, or there's a loop that never meets its exist condition or something.

 

And I figured you weren't getting a crash since you mentioned that it got stuck.

 

You should push this to a github so that people can see updated code as you change things, and see the big picture.

For instance, we have no dimension code, and can't see the resource location of the dimension. Sometimes something that appears unrelated might have something to do with the problem, that's why when I have an issue I always share all my code, I figure since I'm asking for help, what do I know what code is relevant or not?

[Budschie]

@Ugdhar I sadly have no github.

It's free, there's no reason to not have one! And it's so helpful. Not to mention if you're not using git, you should start, because its awesome. Here are some links that may help you get started, don't be scared!

Congratulations, you shortened my code by TWO CHARACTERS.

@Ugdhar I think I have now set up my github repo, please tell me if I did

something wrong. Link: https://github.com/Budschie/Deepnether-Mod

Hmm, where are you registering your DimensionType? I can't seem to find it anywhere, and based on the first post it was supposed to be in DimensionInit.

 

Also, I noticed there are still a few references to examplemod in your mods.toml and build.gradle, don't forget to change them to reference deepnether

[Budschie]

@Ugdhar Thanks. How do I register my DimensionType with a deferred register?
