Subject: [PATCH] Seed based feature search
|
|
|
|
This fixes 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 using the same seed checking functionality that is used
|
|
by the server when generating these features before actually attempting
|
|
to load the chunk to check if a feature is available in it.
|
|
|
|
The only 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 improvement is added though in case that should ever be necessary.
