- Use enums for key and mouse actions, rather than integer ids.
- Change TerminalState to always contain a terminal. We now make
TerminalState nullable when we want to skip sending anything.
- Update Gradle to 8.7
- Configure IntelliJ to build internally, rather than delgating to
Gradle. We've seen some weird issues with using delegated builds, so
best avoided.
- Remove gitpod config. This has been broken for a while (used Java 16
rather than 17) and nobody noticed, so I suspect nobody uses this.
- Add the core TeaVM jar to the runtime the classpath, to ensure
various runtime classes are present.
- Fix computer initialisation errors not being displayed on the screen.
The terminal was set to the default 0x0 size when logging the error,
and so never displayed anything!
Rather than handling right clicks within the block entity code, we now
handle it within the block. Turtles now handle the nametagging
behaviour themselves, rather than overriding canNameWithTag.
Minecraft.hitResult may /technically/ be null when rendering a turtle.
In vanilla, this doesn't appear to happen, but other mods (e.g.
Immersive Portals) may still take advantage of this.
This hitResult is then propagated to BlockEntityRenderDispatcher, where
the field was /not/ marked as nullable. This meant we didn't even notice
the potential of an NPE!
Closes#1775
This fixes several issues with @Nullable fields not being checked. This
is great in principle, but a little annoying in practice as MC's
@Nullable annotations are sometimes a little overly strict -- we now
need to wrap a couple of things in assertNonNull checks.
This theoretically allows you to use the emulator to run the test suite
(via --mount-ro projects/core/src/test/resources/test-rom/:test-rom),
but not sure how useful this is in practice.
This tells Create that modems will pop-off if their neighbour is moved,
and so changes the order that the block is moved in.
We possibly should use BlockMovementChecks.AttachedCheck instead, to
properly handle the direction modems are facing in. However, this
doesn't appear to be part of the public API, so probably best avoided.
Fixes#948
When the terminal data is not present, width/height are set to 0, rather
than the terminal's width/height. This meant we'd create an empty
terminal, which then crashes when we try to render it.
We now make the terminal nullable and initialise it the first time we
receive the terminal data. To prevent future mistakes, we hide
width/height, and use TerminalState.create everywhere.
Fixes#1765
- Mention the timer event in os.startTimer. Really we should have a
similar example here too, but let's at least link the two for now.
- Fix strftime link
I have mixed feelings about speaker.playSound. On one hand, it's pretty
useful to be able to play any sound. On the other, it sometimes feels
... maybe a little too magic?
One particular thing I don't like is that it allows you to play
arbitrary records, which sidesteps both a vanilla mechanic (finding
record discs) and existing CC functionality (disk.playAudio). We now
prevent playing record tracks from the speaker.
In 5d8c46c7e6, we switched to using UUIDs
for looking up computers (rather than an integer ID). However, for
compatibility in some of the command code, we need to maintain the old
integer lookup map.
Most of the code was updated to handle this, *except* the code to remove
a computer from the registry. This meant that we'd fail to remove a
computer from the UUID lookup map, so computers ended up in a phantom
state where they were destroyed, but still accessible.
This is not an issue on 1.20.4, because the legacy int lookup map was
removed.
Fixes#1760
The two mod loaders expose different methods for this (Forge's method
takes a ItemPropertyFunction, Fabric's a ClampedItemPropertyFunction).
This is fine in a Gradle build, as the methods are compatible. However,
when running from IntelliJ, we get crashes as the common code tries to
reference the wrong method.
We now pass in the method reference instead, ensuring we use the right
method on each loader.
BYTECODE WAS NOT SUPPOSED TO BE REWRITTEN
YEARS OF DEBUGGING REMAPPING FAILURES yet NO ACTUAL SOLUTION FOUND.
Wanted to use Mixins for anyway for a laugh? We had a tool for that: it
was called "FABRIC LOOM".
"Yes, please produce completely broken jars for no discernable reason"
Statements dreamed up by the utterly Deranged.

This removes our two mixins used on Forge:
- Breaking progress for cabled/wired modems.
- Running client commands from chat click events. We now suggest the
command on Forge instead.
Occasionally we get issues where the mixin annotation processor doesn't
write its tsrg file in time for the reobfJar/reobfJarJar task. I thought
we'd fixed that cb8e06af2a, but sometimes
we still produce missing jars - I have a feeling this might be to do
with incremental compilation.
We can maybe re-evaluate this on 1.20.4, where we don't need to worry
about remapping any more.
We were seeing some strange issues in the Fabric test code where we
tried to load the implementation from a different classloader. This
ensures that the classloaders are consistent.
Due to the asynchronous nature of main-thread tasks, it's possible for
them to be executed on peripherals which have been detached. This has
been known for a long time (#893 was opened back in 2021), but finding a
good solution here is tricky.
Most of the time the method will silently succeed, but if we try to
interact with an IComputerAccess (such as in inventory methods, as seen
in #1750), we throw a NotAttachedException exception and spam the logs!
This is an initial step towards fixing this - when calling a peripheral
method via peripheral.call/modem.callRemote, we now wrap any enqueued
main-thread tasks and silently skip them if the peripheral has been
detached since.
This means that peripheral methods may start to return nil when they
didn't before. I think this is *fine* (though not ideal for sure!) - we
return nil if the peripheral has been detached, so it's largely
equivalent to that.
Double chests peripherals were getting reattached every time there was a
block update, as the inventories were not comparing equal (despite being
so!). We now check for a couple of common cases, which should be enough
for vanilla/vanilla-like inventories.
I actively Do Not Like This Code, but do not see a good alternative.
This should never happen, but apparently it does!? We now log an error
(rather than crashing), and include the original BE (and associated
block), as the BE type isn't very useful.
See #1750. Technically this fixes it, but want to do some more poking
there first.
Here's a fun bug you can try at home:
- Create a new world
- Spawn in a pocket computer, turn it on, and place it in a chest.
- Reload the world - the pocket computer in the chest should now be
off.
- Spawn in a new pocket computer, and turn it on. The computer in chest
will also appear to be on!
This bug has been present since pocket computers were added (27th March,
2024).
When a pocket computer is added to a player's inventory, it is assigned
a unique *per-session* "instance id" , which is used to find the
associated computer. Note the "per-session" there - these ids will be
reused if you reload the world (or restart the server).
In the above bug, we see the following:
- The first pocket computer is assigned an instance id of 0.
- After reloading, the second pocket computer is assigned an instance
id of 0.
- If the first pocket computer was in our inventory, it'd be ticked and
assigned a new instance id. However, because it's in an inventory, it
keeps its old one.
- Both computers look up their client-side computer state and get the
same value, meaning the first pocket computer mirrors the second!
To fix this, we now ensure instance ids are entirely unique (not just
per-session). Rather than sequentially assigning an int, we now use a
random UUID (we probably could get away with a random long, but this
feels more idiomatic).
This has a couple of user-visible changes:
- /computercraft no longer lists instance ids outside of dumping an
individual computer.
- The @c[instance=...] selector uses UUIDs. We still use int instance
ids for the legacy selector, but that'll be removed in a later MC
version.
- Pocket computers now store a UUID rather than an int.
Related to this change (I made this change first, but then they got
kinda mixed up together), we now only create PocketComputerData when
receiving server data. This makes the code a little uglier in some
places (the data may now be null), but means we don't populate the
client-side pocket computer map with computers the server doesn't know
about.
- Remove "initial connections" flag, and just refresh connections +
peripherals on the first tick.
- Remove "peripheral attached" from NBT, and just read/write it from
the block state. This might cause issues with #1010, but that's
sufficiently old I hope it won't!
Our GatedPredicate hack was clever, but also fundamentally didn't work.
The predicate is called before extraction, so if extraction fails (for
instance, canTakeItemThroughFace returns false), then we still think an
item has been removed.
To fix that, we inline StorageUtil.move, specialising it for what we
need.
This feels a little overkill, but nice to standardise how this code
looks.
There's a bit of me which wonders if we should remove
IPeripheral.equals, and just use Object.equals, but I do also kinda like
the explicitness of the current interface? IDK.
