Hi, this isn't something TF can address.

Consider doing something like the following to get the world from wherever:

ServerWorld world = ServerLifecycleHooks.getCurrentServer().getWorld(World.OVERWORLD);

Or if you need to stick with mixins maybe mixin-implement IChunk::getWorldForge on the ChunkPrimer so you can get the world using that instead of downcasting.

Hello,

I also see an issue with the new BetterCaves-Forge-1.16.4-1.1.

Other version are: MC 1.16.4 and Forge-35.1.36.

Loaded into a personal survival game which loaded, however when I moved into an undiscovered chuck MC crashed.

For anyone with this issue just reloading previous Better Caves version: fixed the crash and world was playable again.

If it helps here is the crash report: And Thank you for the great mod....

Can confirm I am getting the same error.

TelepathicGrunt · Answer 5 · 2021-01-15T13:51:23.000Z

@Won-Ton pretty sure mixins cannot apply to interfaces. I believe that was what murfrey was working on. Why can’t terraforged have ChunkDelegate extend one of the non-interface chunk classes and then override the methods needed? That would resolve this crash and possible prevent any future crash with mods that expect a vanilla chunk class

also, another issue with the serverlifecycle is, you don’t know what dimension you’re in. Carvers can run in any dimension so that’s not a solution but just puts the problem back to square one. Especially as iirc, Better Caves allows users to swap cavers to move them around any dimension so the context of the current world that the carver is in is needed. And it isn’t just gonna be the overworld

yungnickyoung · Answer 6 · 2021-01-15T17:30:54.000Z

My issue with overriding getWorldForge is that my mod now becomes contingent on that method being present, which could change on a whim by the Forge team. If that method gets changed or removed, we'll be back to square one with this issue. Mixing into vanilla chunk classes is a much more resilient solution.

TelepathicGrunt · Answer 7 · 2021-01-15T18:08:30.000Z

Won-Ton, ah that's right. I forgot forge patched in the getWorldForge. However, when trying to test mixin into the method, I dont think it is possible anyway. I tried looking up info on mixins into interfaces and all I could find is that mixins cant really do much with interfaces such as adding a field or new methods.

I still took a stab and tried this but getWorldForge still returns null. And I kind of agree with Nick as it feels like getWorldForge is legacy code that Forge would be likely to remove after another refactor although it is used in ChunkDataEvent.
https://gist.github.com/TelepathicGrunt/e733035c0a2af0e8f36c340b6c894b52

If you know how to make a working example mixin into the IChunk interface and get it to store/get the world along with the boolean of if the chunk was carved or not, then please share it. I don't see many options on Better Caves's end.

Edit: I see my mistake is that ChunkPrimerMixin doesn't implement IChunk but it needs to implement IServerWorldHolder. Classes cannot implement two interfaces at once which adds another layer of complexity to the problem.

TelepathicGrunt · Answer 8 · 2021-01-15T15:18:44.000Z

Was talking with someone and the only other solution Better Caves can even try is mixin a new world field into WorldCarver, then mixin into ChunkGenerator's carve method, and in the loop over configuredcarvers, and set the world of the configuredcarver's inner WorldCarver's world field. However, there is concerned about concurrency issues with this which might need the use of threadlocals.

also, chunkgenerators doesnt have a world either so we are... back to square one again.

Honestly, the safest and best solution is terraforged just extends one of the non-interface chunk classes. Would help prevent better caves having to do even more concerning hacks just to work with terraforged

Won-Ton · Answer 9 · 2021-01-15T16:17:37.000Z

@Won-Ton pretty sure mixins cannot apply to interfaces. I believe that was what murfrey was working on. Why can’t terraforged have ChunkDelegate extend one of the non-interface chunk classes and then override the methods needed? That would resolve this crash and possible prevent any future crash with mods that expect a vanilla chunk class

ChunkPrimer implements IChunk which has forge's default IWorld getWorldForge() { return null; } patched onto it.
You can add an override for that onto ChunkPrimer via mixin in exactly the same way as is being done with IServerWorldHolder .

TF doesn't/won't extend ChunkPrimer because of allocations (ChunkPrimer is full of a bunch of initialized maps/lists/arrays).
The contract for ChunkCarver is IChunk which TF fulfills. Mojang's generator design is relatively strict on what it exposes to each generation step (with good reason) so it's on (the proverbial) 'you' if you want to circumvent it.

also, another issue with the serverlifecycle is, you don’t know what dimension you’re in. Carvers can run in any dimension so that’s not a solution but just puts the problem back to square one. Especially as iirc, Better Caves allows users to swap cavers to move them around any dimension so the context of the current world that the carver is in is needed. And it isn’t just gonna be the overworld

This is true. It was just a suggestion in case it fitted this mod's usecase.

yungnickyoung · Answer 10 · 2021-01-15T20:50:35.000Z

@Won-Ton Can you publish a 1.16 build? I'm gonna try to plug into your API and use the delegate chunk.

TelepathicGrunt · Answer 11 · 2021-01-15T18:17:23.000Z

@yungnickyoung for now, what you could do is wrap all casts in an if(chunk instanceof IServerWorldHolder){ ... } and treat the chunk as overworld and uncarved if the check fails. That would prevent the crash with terraforged until a better solution arises.

Won-Ton · Answer 12 · 2021-01-15T18:23:49.000Z

@TelepathicGrunt

interface IServerWorldHolder extends IChunk

The hasCarved marker stuff would need another solution but that'd be trivial to solve

Won-Ton · Answer 13 · 2021-01-15T21:56:38.000Z

@TelepathicGrunt For reference, this is what I was getting at - you mixin-implement the interface, not try mixin into the default method:

interface IChunk {
    ...
    default IWorld getWorldForge() {
        return null
    }
}

interface IServerWorldHolder extends IChunk {
    void setWorldForge(IWorld world);
}

@Mixin(ChunkPrimer.class)
abstract class MixinChunkPrimer implements IServerWorldHolder {

    private IWorld worldForge;

    @Override
    public IWorld getWorldForge() {
        return worldForge;
    }

    @Override
    public void setWorldForge(IWorld world) {
        this.worldForge = world;
    }
}

Anywho, I've submitted an alternative approach which I think should be a lot more solid go forward

yungnickyoung · Answer 14 · 2021-01-16T03:37:32.000Z

Thanks everyone for your help. I just uploaded v1.1.1, which should hopefully fix this issue. Please let me know if it works for you! I'll leave this issue open a little while longer in case it doesn't.

TheOrionsun · Answer 16 · 2021-01-16T12:59:49.000Z

Looks to be working.... Loaded old version generated world with all but a few chunks trimmed to reset most of it loaded fine where it would not before.

Very nice mod including better mineshafts mod....Just what MC needed.

Thank you for all your time,
