Subject: [PATCH] Fix CraftEntity hashCode
|
|
|
|
hashCodes are not allowed to change, however bukkit used a value
|
|
that does change, the entityId.
|
|
|
|
When an entity is teleported dimensions, the entity reference is
|
|
replaced with a new one with a new entity ID.
|
|
|
|
For hashCode, we can simply use the UUID's hashCode to keep
|
|
the hashCode from changing.
|
|
|
|
equals() is ok to use getEntityId() because equals() should only
|
|
be true if both the left and right are the same reference.
|
|
|
|
Since entity ids can not duplicate during runtime, this
|
|
check is essentially the same as this.getHandle() == other.getHandle()
|
|
|
|
However, replaced it too to make it clearer of intent.
