Subject: [PATCH] Be more tolerant of invalid attributes
|
|
|
|
Prior to this commit, the player would be disconnected if they ever encountered an attribute with a name that did
|
|
not match Bukkit's expected vanilla scheme. It appears that datapacks can set whatever attribute name they want,
|
|
ignoring vanilla's typical scheme.
|
|
|
|
In a more perfect world the API would expose some way to interact with these attributes, however Bukkit is not
|
|
particularly flexible in this area. Perhaps this is an area for future expansion at a later time.
