Subject: [PATCH] Seed based feature search
|
|
|
|
This tries to work around the issue where the server will load
|
|
surrounding chunks up to a radius of 100 chunks in order to search for
|
|
features e.g. when running the /locate command or for treasure maps
|
|
(issue #2312).
|
|
This is done by backporting Mojang's change in 1.17 which makes it so
|
|
that the biome (generated by the seed) is checked first if the feature
|
|
can be generated before actually to load the chunk.
|
|
|
|
Additionally to that the center location of the target chunk is simply
|
|
returned if the chunk is not loaded to avoid the sync chunk load.
|
|
As this can lead to less precise locations a toggle is provided to
|
|
enable the sync loading of the target chunk again.
|
|
|
|
The main downside of this is that it breaks once the seed or generator
|
|
changes but this should usually not happen. A config option to disable
|
|
this completely is added though in case that should ever be necessary.
