The connection used to happen during enter_tree, but this was causing
issues when setting the spawnable scenes from code.
The spawner now connects/disconnects to the signal during
add_spawnable_scene/clear_spawnable_scenes if the node is inside tree
and has a valid spawn_path.
We want our spawns to be notified after ready, but we need to notify
them in the order they entered tree, so that nested spawners can be used
during "ready" (instead of having to await a frame).
Renamed to "spawn_function".
Allow both custom spawn and auto spawn list to co-exist.
This makes it possible to implement custom spawn without being forced to
attach a script to MultiplayerSpawner directly.
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".
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.
