It is incorrect. (Parallel processing incorrect too. But i did it) Main pros:
I try to do this already :( |

@tolziplohu I know you had some questions about this. What should we do with this PR? Put it back in Draft status? |
It sounds like if chunks aren't marked ready until light merging happens, that would probably solve the problems @DarkWeird identified. I don't much time currently though, so I'll mark it as a draft for now. |

Most of the complexity around
ChunkProcessingPipelineis because of the need to support chunk tasks which require neighboring chunks. The only task which requires that is light merging, so this PR experiments with moving light merging to after the main chunk processing phase. This makes it so that chunks appear in the world immediately after their generated, but will have their lighting updated when neighboring chunks are generated, instead of waiting for the neighbors to generate to appear at all. It also meansChunkProcessingPipelinecan be removed entirely, and replaced with fairly simple usage of the Reactor APIs.How to test
Try generating a world, loading a world, playing in multiplayer. My multiplayer doesn't really seem to work right now anyway so I haven't tested whether this PR breaks it.
Outstanding before merging
Is there any reason besides light merging to support chunk tasks with multiple requirements? If so, the complexity might be worth it.
