Subject: [PATCH] Fix advancement triggers on entity death
|
|
|
|
This fixes PaperMC/Paper#3729 and PaperMC/Paper#4252
|
|
|
|
Paper changes logical order revolving around making the EntityDeathEvent
|
|
cancellable. Reordering this logic has ended up with entity equipment being
|
|
cleared _before_ advancement criteria can run, causing things like killing
|
|
raid captains not giving the voluntary exile advancement.
|
|
|
|
This fixes the issue by storing a copy of the equipment in a new field just
|
|
before doing the death event logic where the equipment is cleared and then
|
|
restoring it back to the entity just before the criterion triggers run and
|
|
then finally clearing the equipment again right after the criterion is done.
