The VBO renderer needs to generate a buffer with two quads for each
cell, and then transfer it to the GPU. For large monitors, generating
this buffer can get quite slow. Most of the issues come from
IVertexBuilder (VertexConsumer under MojMap) having a lot of overhead.
By emitting a ByteBuffer directly (and doing so with Unsafe to avoid
bounds checks), we can improve performance 10 fold, going from
3fps/300ms for 120 monitors to 111fps/9ms.
See 41fa95bce4 and #1065 for some more
context and other exploratory work. The key thing to note is we _need_ a
separate version of FWFR for emitting to a ByteBuffer, as introducing
polymorphism to it comes with a significant performance hit.
- Move all RenderType instances into a common class.
Cherry-picked from 41fa95bce4408239bc59e032bfa9fdc7418bcb19:
- Render GL_QUADS instead of GL_TRIANGLES.
- Remove any "immediate mode" methods from FWFR. Most use-cases can be
replaced with the global MultiBufferSource and a proper RenderType
(which we weren't using correctly before!).
Only the GUI code (WidgetTerminal) needs to use the immediate mode.
- Pre-convert palette colours to bytes, storing both the coloured and
greyscale versions as a byte array.
Cherry-picked from 3eb601e55402536d752720e9474ab4ecb27d2f5f:
- Pass lightmap variables around the various renderers. Fixes#919 for
1.16!
A little shorter and more explicit than constructing the Vector3d
manually. Fixes an issue where sounds were centered on the bottom left
of speakers, not the middle (see cc-tweaked/cc-restitched#85).
See #1061, closes#1064.
Nobody ever seems to implement this correctly (though it's better than
1.12, at least we've not seen any crashes), and this isn't a fight I
care enough about fighting any more.
There's a couple of alternative ways to solve this. Ideally we'd send
our network messages at the same time as MC does
(ChunkManager.playerLoadedChunk), but this'd require a mixin.
Instead we just rely on the fact that if the chunk isn't loaded,
monitors won't have done anything and so we don't need to send their
contents!
Fixes#1047, probably doesn't cause any regressions. I've not seen any
issues on 1.16, but I also hadn't before so ¯\_(ツ)_/¯.
This was added in the 1.13 update and I'm still not sure why. Other mods
seem to get away without it, so I think it's fine to remove.
Also remove the fake net manager, as that's part of Forge nowadays.
Fixes#1044.
- Fixes#1026
- The remaining bytes counter wasn't being decremented, so the code that
splits off smaller packets was unreachable. Thus all file slices were
being put into a single UploadFileMessage packet.
- Fix UpgradeSpeakerPeripheral not calling super.detach (so old
computers were never cleaned up)
- Correctly lock computer accesses inside SpeakerPeripheral
Fixes#1003.
Fingers crossed this is the last bug. Then I can bump the year and push
a new release tomorrow.
We're still a few days away from release, but don't think anything else
is going to change. And I /really/ don't want to have to write this
changelog (and then merge into later versions) on the 25th.
While Minecraft will automatically push a new buffer when one is
exhausted, this doesn't help if there's only a single buffer in the
queue, and you end up with stutter.
By enquing a buffer when receiving sound we ensure there's always
something queued. I'm not 100% happy with this solution, but it does
alleviate some of the concerns in #993.
Also reduce the size of the client buffer to 0.5s from 1.5s. This is
still enough to ensure seamless audio when the server is running slow (I
tested at 13 tps, but should be able to go much worse).
When the game is paused in SSP world, speakers are not ticked. However,
System.nanoTime() continues to increase, which means the next tick
speakers believe there has been a big jump and so schedule a bunch of
extra audio.
To avoid this, we keep track of how long the game has been paused offset
nanoTime by that amount.
Fixes#994
It's just more confusing having to keep track of where the ByteBuffer is
at. In this case, I think we were forgetting to rewind after computing
the digest.
Hopefully we'll be able to drop some of these in 1.17 as Java 16 has
a few more ByteBuffer methods
Fixes#992
Speakers can now play arbitrary PCM audio, sampled at 48kHz and with a
resolution of 8 bits. Programs can build up buffers of audio locally,
play it using `speaker.playAudio`, where it is encoded to DFPWM, sent
across the network, decoded, and played on the client.
`speaker.playAudio` may return false when a chunk of audio has been
submitted but not yet sent to the client. In this case, the program
should wait for a speaker_audio_empty event and try again, repeating
until it works.
While the API is a little odd, this gives us fantastic flexibility (we
can play arbitrary streams of audio) while still being resilient in the
presence of server lag (either TPS or on the computer thread).
Some other notes:
- There is a significant buffer on both the client and server, which
means that sound take several seconds to finish after playing has
started. One can force it to be stopped playing with the new
`speaker.stop` call.
- This also adds a `cc.audio.dfpwm` module, which allows encoding and
decoding DFPWM1a audio files.
- I spent so long writing the documentation for this. Who knows if it'll
be helpful!
- Remove all the hungrarian notation in variables. Currently leaving
the format of rednet messages for now, while I work out whether this
counts as part of the public API or not.
- Fix the "repeat" program failing with broadcast packets. This was
introduced in #900, but I don't think anybody noticed. Will be more
relevant when #955 is implemented though.
This means that if the current player is breaking a cable/wired modem,
only the part they're looking at has breaking progress. Closes#355.
A mixin is definitely not the cleanest way to do this. There's a couple
of alternatives:
- CodeChickenLib's approach of overriding the BlockRendererDispatcher
instance with a delegating subclasss. One mod doing this is fine,
several is Not Great.o
- Adding a PR to Forge: I started this, and it's definitely the ideal
solution, but any event for this would have a ton of fields and just
ended up looking super ugly.
I assume people have broken coroutine dispatchers - I didn't think it
was possible to queue an actual event with no type.
See cc-tweaked/cc-restitched#31. Will fix it too once merged downstream!
