Subject: [PATCH] Fix cancelling ProjectileHitEvent for piercing arrows
|
|
|
|
Piercing arrows search for multiple entities inside a while
|
|
loop that is checking the projectile entity's removed state.
|
|
If the hit event is cancelled on the first entity, the event will
|
|
be called over and over again inside that while loop until the event
|
|
is not cancelled. The solution here, is to make use of an
|
|
already-existing field on AbstractArrow for tracking entities hit by
|
|
piercing arrows to avoid duplicate damage being applied.
|
|
|
|
== AT ==
|
|
protected net.minecraft.world.entity.projectile.Projectile hitCancelled
