Still one TODO left, but around data fixers, so fairly small.
- GUI rendering got a big overhaul. I avoided the worst of it with
9272e2efcd5a13f1796609652c1739b9d91b73fe, but things like terminals
and printouts still require some custom rendering.
- Item models are now de-duplicated when rendering in the UI, so we
need to keep track of their identity with
(appendModelidentityElement). I'm not sure I've got this entirely
right — whole thing feels unfortunately error-prone.
- BE serialisation now goes through a Value{Input,Output} class, rather
than using NBT directly. Fairly simple change, but has changed the
format of the GameProfile used in turtle's owners. Need a DFU patch
for this.
- Use new tooltip component registry. This means we can move the
tooltip appending magic to Neo only.
- Use new chunk level change event. I'm not actually sure if we need
this on recent versions (I can't reproduce the monitor update bug
that we introduced this to fix), but I've no clue what's changed here.
0/10, would not recommend. Though increasingly feeling that about
modding as a whole — really not feeling as emotionally rewarding as it
once did.
Server-side changes are well, not simple, but relatively straightforward:
- Block removal code is now called before the BE is removed, not after.
- Monitors now need to track if they've being removed or not again.
- Turtle drop consuming code no longer tries to insert items into
the turtle immediately, instead waiting 'til the action is
complete. Otherwise if the turtle gets destroyed mid-action
(e.g. the block explodes), then it tries to insert its drops into
itself!
We previously guarded against this by checking if the turtle BE had
been removed, but obviously this no longer works, so just easier to
shift the insertion.
- The interface for reading/writing NBT has been overhauled. It has
native "getOr" and codec support (nice!) but also has been changed
again in the latest snapshot (less nice!).
- The dye item component no longer has a "hide tooltip" flag. We now
hide the tooltip with a default component instead.
- Related to the above, we can now do all the tooltip-related things we
needed to do with vanilla's TooltipProvider. This did require
splitting NonNegativeId into subclasses for disk/computer, but
otherwise is quite nice.
- Some changes to model datagen. Annoying, but boring.
- Game tests got a complete overhaul. I'm keeping the interface the
same for now (@GameTest), because I'm blowed if I'm datagenning test
instances :p. If it's any consolation, both NF and Fabric are doing
this too.
Client changes are a bit more involved though:
- VertexBuffer has been entirely removed. We now construct the
GpuBuffer directly.
- BakedModel is gone! Oh this caused so much suffering for turtle
models. I ended up rewriting the whole system in processes (which
then involved PRs to NF and Fabric). Rather than returning a
TransformedModel, turtle models are now responsible for rendering the
model.
This may see another rewrite in the future. I'd like to switch to
JSON-based turtle models (like item models), but that's blocked on
some changes to NF right now.
Sorry to all add-on devs, I know this is a big change.
The main thing of note is Spotless, which also bumps the version of
Ktlint. I've been putting this off for a while[^1], as this changed a
bunch of formatting, and Spotless's (broken) caching was making it hard
to test. Ended up downloading ktlint and running it localy.

These just return details about the currently equipped *item*. This
allows us to expose information about the currently equipped upgrade,
without having to invent a whole new format.
Docs are a bit consise, but didn't really know how to flesh them out any
further.
Fixes#964, fixes#1613, closes#1692.
Please don't talk to me about this. The first couple of hours of this
update were quite enjoyable, and then the rest was one of the most
miserable times I've had modding.
This has been a real slog, partly due to some large MC changes (item
models are a great change, but a pain to adapt to), and partly due to
mental health reasons — honestly, I've opened up my IDE so many times,
and then just closed it because I've hated the thought of even working
on this.
I will publish this to my maven, so mod authors can depend on it, but I
have no plans to publish a 1.21.4 version. 1.21.5 is right around the
corner (again, with some cool, but no-doubt painful changes), and I
need some time to focus on some breaking changes.
This commit actually includes the 1.21.3 update — the git history got so
messy here, so I just clobbered the whole thing. Sorry.
== Rendering ==
- Remove TBO monitor renderer: There was a big overhaul to how shaders
are defined and loaded in 1.21.2. It might have been possible to
update the monitor shader code to this version, it doesn't see much
use nowadays, so let's just delete it.
This is a real shame — the TBO renderer was one of my favourite
projects I've worked on. Unfortunately, it just doesn't seem worth
the ongoing maintenance burden. It lives on in the standalone
emulator :D.
- Similarly, the VBO rendering code got a bit of an overhaul. We no
longer use a custom VBO subclass, and instead just hack vanilla's to
support changing the number of vertices rendered.
This does mean we need to construct a MeshData, rather than a raw
ByteBuffer. This isn't too hard, but not sure how it'll play with
Iris. Given recent vanilla performance improvements, maybe we can
remove our Unsafe code and use a normal BufferBuilder now.
- Remove our custom emissive model code, now that vanilla supports
it. We should add emissive textures to some other models at some
point.
- Remove mod-loader specific model code, and replace it with vanilla's
ItemModel. This does constrain the design of turtle upgrade modellers
quite a bit — we now only accept an untransformed BakedModel or a
transformed ItemStack model. We may relax this in the future,
unclear.
This change does mean that updsidedown turtles are broken. RIP :(.
- Entity rendering now separates reading state from the entity from
actual rendering. This means we need to pass some extra state around
for item frames. Easy on Forge, but requires a mixin on Fabric.
== Recipes ==
There were several major changes to ingredients this update. The code
here hasn't been very well tested right now — might be nice to add some
game tests for this.
- Ingredients can no longer be constructed directly from a tag key (it
needs to be fetched from the current registries), so the recipe
generation code needs a bit of a reshuffle.
- DiskRecipe now accepts a custom list of ingredients, rather than
being hard-coded (fixes#1755). Recipes can now return custom
`RecipeDisplay`s used to show a recipe in the crafting book. We use
this to replace the impostor recipes.
I'm not entirely sure how well this'll play with other recipe
mods. Here's hoping.
- Similarly, our recipe mod integration has been updated to use
RecipeDisplay. We had to do this as ingredients no longer accept
arbitrary ItemStacks (only a specific item).
== Misc ==
- Blocks/items now need to know their ID ahead of time (so they can
compute their description). This requires some reshuffling to the
registration code, but it's pretty minor.
- updateShape and neighborChanged no longer take a direction (the
Orientation is mostly null) and so invalidates all redstone and
peripherals.
- All the positions were lowered by one in game tests. It's a good
change (they now match the positions in structures), but annoying to
update for!
Now, hear me out, what if instead of having three @Nullable annotations,
we had *four*?
I've been wanting to switch away from javax.annoations for a while. The
library has been deprecated for ever and, unlike other @Nullable
annotations, the annotation is attached to the parameter/function
itself, rather than the type.
We use JSpecify rather than one of the alternatives (JetBrains,
CheckerFramework) mostly because it's what NullAway recommends. We keep
CheckerFramework around for @DefaultQualifier, and JB's for @Contract.
There are some ugly changes here — for instance, `@Nullable byte[]` is
replace by `byte @Nullable`, and `@Nullable ILuaMachine.Factory` is
`ILuaMachine.@Nullable Factory`. Ughr, I understand why, but it does not
spark joy :).
I removed this in fc834cd97fe941a192e40962ac3bb27be102ce09, way back in
late 2024. Looks like it's been updating in the meantime and I hadn't
noticed, so add it back.
I've simplified the code a little bit, to make use of our NeoForge's new
capability system, but otherwise it's almost exactly the same :D.
As part of this, we also rewrite some of the turtle placing code, and
how it uses the turtle_can_use tag:
Minecraft 1.21 cleaned up the item/block clicking code a little bit,
splitting Block.use into Block.useItemOn and Block.useWithoutItem. The
first of these is pretty much exactly what we wanted in the first place,
so the tag was kinda redundant and we commented it out in the 1.21
update.
This was never meant to be a long-term fix, but time has gone by anyway.
We now check that tag, and call useWithoutItem() if present —
effectively restoring the previous behaviour.
Fixes#2011
Okay, listen. I started writing a few more gametests (see #1682), and
then thought I'd do a cheeky Gradle update. However, that broke
vanilla-extract[^1], and also triggered a load of deprecation warnings,
and at that point it was too late to separate the too.

I've no motivation for modding right now, but always got time for build
system busywork!
CC:T (and CC before that) has always published its API docs. However,
they're not always the most helpful — they're useful if you know what
you're looking for, but aren't a good getting-started guide.
Part of the issue here is there's no examples, and everything is
described pretty abstractly. I have occasionally tried to improve this
(e.g. the peripheral docs in bdffabc08e2eb9895f966c949acc8334a2bf4475),
but it's a long road.
This commit adds a new example mod, which registers peripherals, an API
and a turtle upgrade. While the mod itself isn't exported as part of the
docs, we reference blocks of it using Java's new {@snippet} tag.
- Switch the Forge project to use NeoForge's new Legacy MDG plugin. We
don't *need* to do this, but it means the build logic for Forge and
NeoForge is more closely aligned.
- Add a new SnippetTaglet, which is a partial backport of Java 18+'s
{@snippet}.
- Add an example mod. This is a working multi-loader mod, complete with
datagen (albeit with no good multi-loader abstractions).
- Move our existing <pre>{@code ...}</pre> blocks into the example mod,
replacing them with {@snippet}s.
- Add a new overview page to the docs, providing some getting-started
information. We had this already in the dan200.computercraft.api
package docs, but it's not especially visible there.
Been dragging my feet over this for a while now, but increasingly
uncomfortable with Overwolf. I'm not going to delete the project (or any
existing versions), just not publish any new versions there.
- Move redstone methods out of the IAPIEnvironment, and into a new
RedstoneAccess. We similarly move the implementation from Environment
into a new RedstoneState class.
The interface is possibly a little redundant (interfaces with a
single implementation are always a little suspect), but it's nice to
keep the consumer/producer interfaces separate.
- Abstract most redstone API methods into a separate shared class, that
can be used by both the rs API and the new redstone relay.
- Add the new redstone relay block.
The docs are probably a little lacking here, but I really struggled to
write anything which wasn't just "look, it's the same as the redstone
API".
Iris now has built-in support for NeoForge, so we can use the same
integration on both.
We also re-enable Forge's client tests, and test Iris there too.
Fixes#1967
Under Forge, netty-codec lives on the BOOT layer. However, this means it
does not have access to our jzlib (which lives on the GAME layer). To
fix this, we now shadow netty-codec (and its dependents, like netty-http
and netty-proxy) rather than jar-in-jaring them.
This involves some horrible build logic, but means websocket compression
works on Forge.
Fixes#1958.
- Update to latest NeoForge, fixing issues with config API changes.
Closes#1903.
- Update to latest Fabric, switching to the ender pearl conventional
tag, and new loot API.
In c8eadf401190db2b9c3145f768063097b9c345bd we marked our various modems
as "brittle", which ensures they do not pop-off computers when the whole
structure moves.
However, this still requires the modem to be glued — if the modem is
outside the superglue range, it will still pop off. We can fix it by
registering a special "attached check" for the various modem blocks,
which says that the modem should be moved when the adjacent block does.
Fixes#1913
