This commit completely removes the RPC_MODE_MASTER ("master" keyword),
and renames the RPC_MODE_PUPPET to RPC_MODE_AUTHORITY ("auth" keyword).
This commit also renames the "Node.[get|set]_network_master" methods to
"Node.[get|set]_network_authority".
This commit also renames the RPC_MODE_REMOTE constant to RPC_MODE_ANY.
RPC_MODE_MASTER in Godot 3.x meant that a given RPC would be callable by
any puppet peer on the master, while RPC_MODE_PUPPET meant that it would
be callable by the master on any puppet.
Beside proving to be very confusing to the user (referring to where it
could be called instead of who can call it) the RPC_MODE_MASTER is quite
useless. It is almost the same as RPC_MODE_REMOTE (anyone can call) with
the exception that the network master cannot. While this could be useful
to check in some case, in such a function you would anyway need to check
in code who is the caller via get_rpc_sender_id(), so adding the check
there for those rare cases does not warrants a dedicated mode.
Segment collision results could be different depending on the direction
when they exactly touch (order of the points in segments). This was due
to the way parallelism was checked, using different logic based on
positive or negative sign of cross products.
Now the results are the same whatever the direction, without changing
the current design, which is that parallel or colinear segments are
not considered colinear.
Fixes inconsistencies with raycasts exactly on edges of convex shapes
depending on the direction.
* Exposed functions in Engine to register and unregister singletons.
* Added the concept of user singletons, which can be removed (the system ones can't).
Adds ability to add error return documetation to the binder and class reference.
Usage example:
```C++
void MyClass::_bind_method() {
[..]
BIND_METHOD_ERR_RETURN_DOC("load", ERR_FILE_CANT_OPEN, ERR_FILE_UNRECOGNIZED);
}
```
One function of ConfigFile was changed as example.
* Allows calling into native extensions directly with a pointer
* Makes it easier to implement some APIs more efficiently
* Appears with a "*" in the documentation for the argument.
* Implementing the pointer handling is entirely up to the implementation, although the extension API provides some hint.
* AudioStream has been implemented as an example, allowing to create NativeExtension based AudioStreams.
* `_gui_input`, `_input`, `_unhandled_input` and `_unhandled_key_input` are now regular C++ virutal functions.
* Everything else converted to GDVIRTUAL
* BIND_VMETHOD is gone, always use the new syntax from now on.
Creating `_gui_input` method and using the binder to register events will no longer work, simply override the virtual function now.
The constructor was expecting a mutable pointer, while the passed pointer was immutable ( returns a const pointer), so the compilation was failing when iterating a constant .
* New syntax is type safe.
* New syntax allows for type safe virtuals in native extensions.
* New syntax permits extremely fast calling.
Note: Everything was replaced where possible except for `_gui_input` `_input` and `_unhandled_input`.
These will require API rework on a separate PR as they work different than the rest of the functions.
Added a new method flag METHOD_FLAG_OBJECT_CORE, used internally. Allows to not dump the core virtuals like `_notification` to the json API, since each language will implement those as it is best fits.
* Extensions are now scanned and loaded on demand.
* Extensions found are cached into a file that is used to load them (which is also exported).
* Editor will ask to restart when an extension requires core functionality.
* Editor will attempt to load extensions always before importing or loading scenes. This ensures extensions can register the relevant types.
Capsule height and radius setters can modify each other, rather than
using clamping, to avoid cases where values are not set correctly when
loading a scene (depending on the order of properties).
Inspector undo/redo:
Added the possibility to link properties together in the editor, so
they can be undone together, for cases where a property can modify
another one.
Gizmo undo/redo:
Capsule handles pass both radius and height values so they can be undone
together.
Like the spawn/despawn feature, it can be completely overridden with 2
custom callables.
The callables will be called with the list of tracked objects.
In SERVER mode, objects are automatically tracked, while in CUSTOM mode
you can manually track them via `track`/`untrack` (but that's optional).
The default sync only happens from server to client, with batch updates,
over unreliable channel (but with custom ordering).
The default sync will warn you, if your state representation gets too
big.
Move the former "spawnables" functions to a dedicated
MultiplayerReplicator class.
Support custom overrides in replicator.
Spawn/despawn messages can now contain a state.
The state can be automatically encoded/decoded by passing the desired
object properties to `spawnable_config`.
You can use script properties to optimize the state representation.
2 Callables can be also specified to completely override the default
implementation for sending and receiving the spawn/despawn event.
(9 bytes overhead, and there's room for improvement here).
When using a custom implementation `spawn` and `despawn` can be called
with any Object, `send_spawn`/`send_despawn` can receive any Variant as
a state, and the path is not required.
Two new functions, `spawn` and `despawn`, convey the implementation
independent method for requesting a spawn/despawn of an Object, while
`send_spawn` and `send_despawn` represent the more low-level send event
for a Variant to be used by the custom implementations.
