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.
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.
Peripherals can now have multiple types:
- A single primary type. This is the same as the current idea of a
type - some identifier which (mostly) uniquely identifies this kind
of peripheral. For instance, "speaker" or "minecraft:chest".
- 0 or more "additional" types. These are more like traits, and
describe what other behaviour the peripheral has - is it an
inventory? Does it supply additional peripherals (like a wired
modem)?.
This is mostly intended for the generic peripheral system, but it might
prove useful elsewhere too - we'll have to see!
- peripheral.getType (and modem.getTypeRemote) now returns 1 or more
values, rather than exactly one.
- Add a new peripheral.hasType (and modem.hasTypeRemote) function which
determines if a peripheral has the given type (primary or
additional).
- Change peripheral.find and all internal peripheral methods to use
peripheral.hasType instead.
- Update the peripherals program to show all types
This effectively allows you to do things like
`peripheral.find("inventory")` to find all inventories.
This also rewrites the introduction to the peripheral API, hopefully
making it a little more useful.
- Bump copy-cat version to have support for initial files in
directories and the blit fixes.
- Add an example nft image and move example nfp into a data/ directory.
- Fix nft parser not resetting colours on the start of each line.
Let's see how this goes.
- Update references to the new repo
- Use rrsync on the server, meaning make-doc.sh uploads relative to the
website root.
- Bump Gradle wrapper to 7.2. Not related to this change, but possibly
fixes running under Java 16. Possibly.
Yes, I know this is a terrible feature. But it's been a long week and
I'm so tired.
Also fix the ordering in motd_spec. Who thought putting the month first
was reasonable?
Plan here is to release 1.98 for 1.16.x and 1.17.x and 1.97.1 for
1.15.x. However, will let this sit for a few days while I sort out 1.98
and the 1.17 port just in case any more bugs pop up.
Also add a test for rednet message sending. Hopefully gives some of the
modem and networking code a little bit of coverage (which is clearly the
same as being right :p).
