Allow registering details providers matching any super type, not just
the exact type. This is mostly useful for 1.21, where we can have
providers for any DataComponentHolder, not just item stacks.
This adds a new mechanism for attaching additional objects to a
computer, allowing them to be queried by other mods. This is primarily
designed for mods which add external APIs, allowing them to add APIs
which depend on the computer's position or can interact with the turtle
inventory.
I will stress that the use-cases for custom APIs are few and far
between. Almost all the time a peripheral would be the better option,
and I am wary that this PR will encourage misuse of APIs. However, there
are some legitimate use-cases, and I think we should enable them.
- Add a new "ComputerComponent" class, and several built-in components
(for turtle, pocket and command computers).
- Add a method to `IComputerSystem` to read a component from the
computer. We also add methods to get the level and position of the
computer.
- Move all our existing APIs (built-in turtle, pocket, command) to use
the public API.
We don't actually use this functionality in other projects (e.g.
emulators). In fact the method to add new APIs only exists in the mod
itself!
We still need some mechanism to remove mounts when the computer is
shutdown. We add a new ApiLifecycle interface (with startup and
shutdown hooks), and use those in the ComputerSystem impl.
Oh, I hate the pocket computer code so much. Minecraft was really not
designed to attach this sort of behaviour to computers. This commit is
an attempt of cleaning this up[^1].
Firstly, we move the the pocket computer state (upgrades, light) out of
PocketServerComputer and into a new PocketBrain class. This now acts as
the sole source-of-truth, with all state being synced back to the
original item stack on the entity tick.
This also adds a new PocketHolder interface, which generalises over the
various types that can hold a pocket computer (players and item
entities right now, possibly lecterns in the future).
[^1]: I'd say simplifying, but this would be a lie.
In c8eadf4011 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
This avoids us having to support requireless environments inside
cc.strings.
I do kinda wonder if os.loadAPI-loaded files should also have their own
shared "require", just so we're not loading 10 copies of cc.expect.
Build system:
- Switch to our new maven server. This has a cleaner separation between
published packages and mirrored packages, to avoid leaking those into
other people's builds.
- Update Gradle and Loom versions.
Code:
- Link to definitions instead in the breaking changes page.
- Fix several unused variable warnings.
Other:
- Remove unsupported Minecraft versions from the issue template.
Due to the earlier commits, the only functionality this block entity
adds is to register the command API. This commit:
- Add the command API when constructing the ServerComputer instead.
This is not a good long-term solution (I think we need to make API
factories more powerful), but is sufficient for now.
- Replace usages of CommandComputerBlockEntity with a normal
ComputerBlockEntity.
- Move the command permisssion checks to a new
ComputerFamily.checkUsable method (from
CommandComputerBlockEntity and ViewComputerMenu). I don't feel great
about putting new functionality in ComputerFamily (trying to move
away from it), but I think this is fine for now.
- Use this method from within the computer menu and computer block, to
check whether computers can be interacted with.
- Remove ViewComputerMenu, as it now no longer needs any special
is-usable logic.
Historically we used to have separate menu types for computers and
pocket computers, as the screen had to be initialised with the correct
terminal size.
However, as of c49547b962 (which was
admittedly two years ago now), we have the terminal available when
constructing the screen, and so the code for the two is identical.
This change actually merges the two screens, replacing usages of the
pocket computer UI with the computer one.
Historically (and according to the docs) getAudioTitle returned "false"
when the drive was empty (or had invalid media), and "null" when the
disk had no item. This was accidentally changed in a later refactor --
this change fixes that behaviour.
We keep getting bug reports on 1.20.1 about an Optifine bug that causes
Forge's capabilities to not work (#1458). The cause of this bug is not
immediately visible to users, and can be very confusing when hit.
Optifine have not released a fix for this bug (despite it being reported
a year ago), and we continue to receive bug reports about it.
Nobody likes it when mods complain about other mods. So much Minecraft
drama can be traced back to this, and it's a slippery slope to go down.
I've tried to keep this as unobtrusive as possible — it's just a chat
message at world join, and it'll turn off if the bug is fixed.
Turtles currently read their textures from a single 128x128 sprite
sheet. Most of this texture is unused which means we end up wasting a
lot of the block texture atlas[^1].
This change splits up the turtle textures into individual 32x32
textures[^2], one for each side, and then an additional backpack
texture.
I'm very sorry to any resource pack artists out there. The
tools/update-resources.py script will update existing packs, but does
not (currently) handle non-standard resolutions.
[^1]: It used to be worse: https://github.com/dan200/ComputerCraft/issues/145
[^2]: Turtle textures are a bit weird, in that they mostly *look* 16x16,
but have some detail in places.
