Subject: [PATCH] Ability to apply mending to XP API
|
|
|
|
This allows plugins that give players the ability to apply the experience
|
|
points to the Item Mending formula, which will repair an item instead
|
|
of giving the player experience points.
|
|
|
|
Both an API To standalone mend, and apply mending logic to .giveExp has been added.
