Subject: [PATCH] ExperienceOrb merging/stacking API and fixes
|
|
|
|
Adds an option for maximum exp value when merging orbs
|
|
|
|
Adds ExperienceOrbMergeEvent
|
|
Fired when the server is about to merge 2 experience orbs
|
|
as entities. Plugins can cancel it if they want to ensure experience orbs do not lose important
|
|
metadata such as spawn reason, or conditionally move data from source to target.
|
|
|
|
Fixes an issue where the stacked count was not taking into account
|
|
for mending repairs and when merging with spigot's merge-on-spawn
|
|
logic
|
|
|
|
== AT ==
|
|
public net.minecraft.world.entity.ExperienceOrb count
