Synchronizers for spawned nodes were not correctly keeping track of the
net ID assigned by the remote, preventing the replication from
performing the proper cleanup.
This resulted in errors being thrown when sync messages were received
after despawn (which is possible due to their unreliable nature).
Fix set_multiplayer_authority not resetting the synchronizer.
Fix the reset function not clearing the watchers state.
Skip wrap around check for the first sync packet after reset.
Allows synchronizing (sub-)resource properties, transform components,
etc. by using subnames.
As an example, `.:transform.x` will only synchronize the `x` component
of the root transform instead of the whole transform.
This can also be used to synchronize a resource own properties, as long
as they are synchronizable (i.e. the property itself is not an Object,
RID, or Callable).
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".
The same node can now be controlled by multiple synchronizers at once.
Spawn visibility is composed in OR across multiple synchronizers (i.e.
if any synchronizer is visible to the peer, the object will be spawned).
Synchronizers controlling spawned nodes can now have a different
authority then the one spawning the node, in that case, the spawn
variables for that specific synchronizer are simply ignored (other
synchronizers with the same authority of the spawner will correctly
synchronize variables on spawn).
The SceneReplicationState class has been completly removed, since it was
bloating the implementation, the state is now simply stored in the
SceneReplicationInterface.
MultiplayerSpawner:
- When spawn_path is invalid.
- When the auto spawn list is empty and _spawn_custom is not overridden.
Note: We remove the warning for placeholder scripts since there's no
way of knowing if they have a certain method.
MultiplayerSynchronizer:
- When root_path is invalid.
- 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.
