Another week, another snapshot. We are currently focusing on getting all the
new content that we have planned into the snapshots, but it will take a
little time until we see it all there. This week we have spent some time
laying down the ground work for better boss fight AI and upgrade paths
between worlds, so we can do even cooler stuff in the following weeks’
snapshots.
15w32a
Thanks to everyone who reported bugs for the snapshots last week. We were
very eager to see how many problems are reported for the first snapshots in
many months and we are positively surprised by the fact that we saw less
problems than expected.
Here are some of the improvements since last week:
Improved Ender Dragon fight, now with more cowbell!
Better handling of using items in both the mainhand and offhand.
Some monsters have problems with their vision now, but we don’t have the
time to code glasses for them.
Generic upgrade path for world saves, this is very technical internal
stuff that you’ll only notice if it goes wrong, but it makes our lives easy.
Added a thing to the system with the values. Can’t be more specific, no
spoilers.
And some bug fixes:
[Bug MC-48730] – Nametags still show while player is invisible and on
team
[Bug MC-82833] – Shulker projectile follows player in spectator mode and
creative mode
[Bug MC-84035] – Enderdragon can't die unless perched on portal
[Bug MC-84078] – When fishing rod is cast, all fishing rods look like it
was cast out to sea too
[Bug MC-84253] – almost all potion and tipped arrows are black
[Bug MC-84584] – Placing End Rod on End Rod sends "hslsdjfksdlk" to
output log twice
A note for everybody else: Back up your world before updating. Things will
break, especially in such an early snapshot. Backup your world. Back it up.
Do it now.
