When new advancements are added via the UnsafeValues#loadAdvancement API, it triggers a full datapack reload when this is not necessary. The advancement is already loaded directly into the advancement registry, and the point of saving the advancement to the Bukkit datapack seems to be for persistence. By removing the call to reload datapacks when an advancement is loaded, the client no longer completely freezes up when adding a new advancement. To ensure the client still receives the updated advancement data, we manually reload the advancement data for all players, which normally takes place as a part of the datapack reloading.

Subject: [PATCH] Fix client lag on advancement loading
|
|
|
|
When new advancements are added via the UnsafeValues#loadAdvancement
|
|
API, it triggers a full datapack reload when this is not necessary. The
|
|
advancement is already loaded directly into the advancement registry,
|
|
and the point of saving the advancement to the Bukkit datapack seems to
|
|
be for persistence. By removing the call to reload datapacks when an
|
|
advancement is loaded, the client no longer completely freezes up when
|
|
adding a new advancement.
|
|
To ensure the client still receives the updated advancement data, we
|
|
manually reload the advancement data for all players, which
|
|
normally takes place as a part of the datapack reloading.
