Subject: [PATCH] ExperienceOrb merging/stacking API
|
|
|
|
Adds ExperienceOrbMergeEvent
|
|
Fired when the server is about to merge 2 experience orbs
|
|
Plugins can cancel this if they want to ensure experience orbs do not lose important
|
|
metadata such as spawn reason, or conditionally move data from source to target.
