This field is used to decide whether or not to render the inside-block overlay,
as such we want it to be set while we're in spectator mode).
This wasn't a problem before 1.15 because we also cancel the renderHand call
while we're in spectator mode and the same method which renders your hand also
renders the overlay, so we were inadvertently canceling that at the same time.
With 1.15, that's still the case except when using OF, which splits the method
apart by adding three boolean arguments indicating which part to execute.
For some reason this applied fine in a development environment (even though the
method signature changed significantly), hence why I didn't notice it being
broken. It did not work (just like one would expect) in a live environment.
The new preprocessor version brings first-party support for fabric, in
particular for automatically fetching mappings loom and for
automatically remapping between MC versions via intermediary mappings.
This will come in handy when updating to 1.15.
It also supports automatic remapping between fabric and forge on the
same MC version (by going mcp<->srg<->mojang<->intermediary<->yarn).
Therefore this commit replaces the previous 1.13.2 (forge) subproject
with a 1.14.4-forge one. Instead of manually providing full mappings for
1.14.4-fabric to 1.13.2-forge and partial (classes) for 1.13.2-forge to
1.12.2-forge, we now only need partial (classes) for 1.12.2-forge to
1.14.4-forge and preprocessor will take care of the forge to fabric
step (in fact, our mapping file for that is currently completely empty).
In an attempt to write an IDE (IntelliJ) plugin for quicker and easier
working with the preprocessor (e.g. immediately mapping single files
from within the IDE, jumping between different versions for the same
file), the preprocessor gradle plugin declaration now requires you to
explicitly specify variables in the common.gradle and the overall
relationship between projects in the build.gradle (latter is required
anyway, so the plugin can know where it should map between forge and
fabric and which subprojects are which versions).
Since that necessitated some changes to the build.gradle file, I took
the opportunity to convert it to Kotlin. As such we now also use
Gradle's newer plugin-block with the pluginManagement-block instead of
manually declaring buildScript (not for the common.gradle though), which
imo is nicer anyway and comes with various advantages (see gradle docs).
There were also some remapping bugs fixed and some new ones
introduced (e.g. manually declared inner class mappings seem to no
longer function properly under certain conditions).
There's also support for remapping Kotlin now. Just saying.
Instead use NativeImage on 1.13+ via newly introduced Image class.
See Image docs for details.
Also fixes an issue with thumbnail taking on 1.13+: The original
ScreenshotHelper method is now async, luckily there's a sync
variant and as a bonus it directly returns a NativeImage so we can
skip having to read the screenshot from disk.
This has previously been fixed for quadruple-clicking on the replay
itself but for some reason has not been fixed for simply double-clicking
the "Load" button.
MC clears it scheduled tasks on disconnect. If we don't wait for
that to have happened on the async sender, then we might loose
some of the initial handshake packets (resulting in a dead lock in
fabric's registry syncing code).
The preprocessor should have complained about these but it didn't for
some reason. This commit isn't fixing any imminent bug, it's just
precautionary (and required to compile once the preprocessor is fixed).
