As part of RPCs processing, they need to be sorted reliably across all
peers, so that unique IDs can be assigned to greatly optimize the
network layer.
The RPC configuration nodes are stored in dictionaries which, until
recently, always casted StringName keys to String.
Since method names (keys) in the RPC configuration were StringName,
a side effect of the above change is that sorting the dictionary keys no
longer sort them alphabetically by default (StringName are compared
using their pointers).
This commit changes the RPC processing logic to use sort_custom to
provide a function that can handle the StringName comparison.
This applies our existing style guide, and adds a new rule to that style
guide for modular components such as platform ports and modules:
Includes from the platform port or module ("local" includes) should be listed
first in their own block using relative paths, before Godot's "core" includes
which use "absolute" (project folder relative) paths, and finally thirdparty
includes.
Includes in `#ifdef`s come after their relevant section, i.e. the overall
structure is:
- Local includes
* Conditional local includes
- Core includes
* Conditional core includes
- Thirdparty includes
* Conditional thirdparty includes
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
Implemented using MultiplayerSynchronizers.
If you didn't use the synchronizer visibility features, nothing changes.
If you were using visibility, RPCs to broadcast should now behave as
expected in most configurations (i.e. by sending the RPC to _visible_
peers).
If you want to limit the visibility of RPCs for a node, add a
synchronizer for it, and configure the visibility via
"set_visibility_for" or by adding a visibility filter.
Fix RPC profiler and add average RPC size.
Improve bandwidth debugger to account for all multiplayer traffic
(excluding the lower level peer transformations).
MultiplayerPeer changes:
- Adds is_server_relay_supported virtual method
Informs the upper MultiplayerAPI layer if it can signal peers connected
to the server to other clients, and perform packet relaying among them.
- Adds get_packet_channel and get_packet_mode virtual methods
Allows the MultiplayerAPI to retrieve the channel and transfer modes to
use when relaying the last received packet.
SceneMultiplayerPeer changes:
- Implement peer signaling and packet relaying when the MultiplayerPeer
advertise they are supported.
ENet, WebRTC, WebSocket changes:
- Removed custom code for relaying from WebSocket and ENet, and let it
be handled by the upper layer.
- Update WebRTC to split create_client, create_server, and create_mesh,
with the latter behaving like the old initialize with
"server_compatibility = false", and the first two supporting the upper
layer relaying protocol.
- RPC configurations are now dictionaries.
- Script.get_rpc_methods renamed to Script.get_rpc_config.
- Node.rpc[_id] and Callable.rpc now return an Error.
- Refactor MultiplayerAPI to allow extension.
- New MultiplayerAPI.rpc method with Array argument (for scripts).
- Move the default MultiplayerAPI implementation to a module.
