A lot is broken, but at least we can get in game:
- GUIs render a whole bunch of additional "inventory" text, which we
really don't want.
- Computers load from the wrong location.
- There's some issues with using Forge's tags from outside of JSON
recipes. We need to work out why.
When creating a peripheral or custom Lua object, one must implement two
methods:
- getMethodNames(): String[] - Returns the name of the methods
- callMethod(int, ...): Object[] - Invokes the method using an index in
the above array.
This has a couple of problems:
- It's somewhat unwieldy to use - you need to keep track of array
indices, which leads to ugly code.
- Functions which yield (for instance, those which run on the main
thread) are blocking. This means we need to spawn new threads for
each CC-side yield.
We replace this system with a few changes:
- @LuaFunction annotation: One may annotate a public instance method
with this annotation. This then exposes a peripheral/lua object
method.
Furthermore, this method can accept and return a variety of types,
which often makes functions cleaner (e.g. can return an int rather
than an Object[], and specify and int argument rather than
Object[]).
- MethodResult: Instead of returning an Object[] and having blocking
yields, functions return a MethodResult. This either contains an
immediate return, or an instruction to yield with some continuation
to resume with.
MethodResult is then interpreted by the Lua runtime (i.e. Cobalt),
rather than our weird bodgey hacks before. This means we no longer
spawn new threads when yielding within CC.
- Methods accept IArguments instead of a raw Object array. This has a
few benefits:
- Consistent argument handling - people no longer need to use
ArgumentHelper (as it doesn't exist!), or even be aware of its
existence - you're rather forced into using it.
- More efficient code in some cases. We provide a Cobalt-specific
implementation of IArguments, which avoids the boxing/unboxing when
handling numbers and binary strings.
So very little works, but it compiles and runs.
Things to resolve over the next few days:
- Horrible mappings (should largely be resolved by tomorrow).
- Cannot send extra data over containers - we'll have to see what Forge
does here.
- Turtle models are broken
- No block drops yet - this will largely be cherry-picking whatever I
did on Fabric.
- Weird inventory desyncs (items don't show up initially when
interacting with a CC inventory).
- Probably lots of other things.
Look, I originally had this split into several commits, but lots of
other cleanups got mixed in. I then backported some of the cleanups to
1.12, did other tidy ups there, and eventually the web of merges was
unreadable.
Yes, this is a horrible mess, but it's still nicer than it was. Anyway,
changes:
- Flatten everything. For instance, there are now three instances of
BlockComputer, two BlockTurtle, ItemPocketComputer. There's also no
more BlockPeripheral (thank heavens) - there's separate block classes
for each peripheral type.
- Remove pretty much all legacy code. As we're breaking world
compatibility anyway, we can remove all the code to load worlds from
1.4 days.
- The command system is largely rewriten to take advantage of 1.13's
new system. It's very fancy!
- WidgetTerminal now uses Minecraft's "GUI listener" system.
- BREAKING CHANGE: All the codes in keys.lua are different, due to the
move to LWJGL 3. Hopefully this won't have too much of an impact.
I don't want to map to the old key codes on the Java side, as there
always ends up being small but slight inconsistencies. IMO it's
better to make a clean break - people should be using keys rather
than hard coding the constants anyway.
- commands.list now allows fetching sub-commands. The ROM has already
been updated to allow fancy usage such as commands.time.set("noon").
- Turtles, modems and cables can be waterlogged.
When a player places a turtle, they are marked as its owner. Any actions
they perform (such as breaking blocks, moving, etc...) are performed
using this player's game profile.
This allows turtles to work correctly with various permissions mods.
Previously you would have to whitelist all turtles in order for them to
function within a claim.
- Makes ITurtleItem implement IColourableItem
- Only cache one turtle item model for all colours, rather than one for
each colour.
- Allow ITurtleAccess to set an arbitrary colour.
- Make InventoryUtil deal with item handlers instead. This
significantly simplifies the implementation, the interface now
does most of the hard work.
- Add InvWrapper item handlers to printers, disk drives and turtles
- Add IItemHandlerModifiable accessor to ITurtleAccess
- Migrate all other inventory code (mostly turtle commands) to use
item handlers instead.
Updated the source code to the version shipped as the 1.80pr0 alpha
release. Also removed some unnecessary files from the LuaJ subfolder
which were bulking up the repository.
