When node tree `A` is not in the tree, `remove_child(B)` will not
automatically clean up the owners of `B` and `B`'s child nodes.
This is convenient for implementing operations like `replace_by()`,
but may have hidden dangers when manipulating the rest of the tree
`A`.
This commit makes it safe to manipulate the rest of `A` after freeing
`B`.
* Node processing works on the concept of process groups.
* A node group can be inherited, run on main thread, or a sub-thread.
* Groups can be ordered.
* Process priority is now present for physics.
This is the first steps towards implementing https://github.com/godotengine/godot-proposals/issues/6424.
No threading or thread guards exist yet in most of the scene code other than Node. That will have to be added later.
* Adding and removing child nodes is now constant time, speed up should be huge.
* Searching for node paths as in ("path/to/node") should be far faster too.
This changes the children management and makes it a hashmap, optimizing most StringName based operations.
Most operations should be severe speed up without breaking compatibility.
This should fix many issues regarding to node access performance, and may also speed up editor start/end, but benchmarks are needed. So if you want to test, please make some benchmarks!
Further performance improvements will be done in the future by removing NOTIFICATION_MOVED_IN_PARENT and replacing by something less laborious.
With change 104392e the code to update node indices on removal was erronously removed.
The out of date indices would cause crashes while selecting nodes in a graph editor (e.g. animation tree) and selected nodes are oftern pushed to beginning or end of the child list for the parent.
* This notification makes node children management very inefficient.
* Replaced by a NOTIFICATION_CHILDREN_CHANGED (and children_changed signal).
* Changed Canvas code (and similar) to use the above signal, to perform more efficiently.
This PR breaks compatibility (although this notification was very rarely used, even within the engine), but provides an alternate way to do the same.
It is required for the changes in #75627 to be entirely effective.
After a scene reload a mouse cursor updates is performed via a
InputEventMouseMotion, that is exposed to the user.
The state of Input is however not adjusted to this InputEventMouseMotion
which can lead to inconsistencies.
This PR makes sure, that it is not exposed to the user.
It utilizes the method of Viewport::_process_picking for marking
events that are not sent to the user, so that this function doesn't
need to be changed.
You still need to select another node to see the tooltip updated first,
but you no longer need to save and reopen the scene to view the updated
tooltip.
* This behavior is not allowed, the error text suggests using call_deferred().
* Added a check in Node::remove_child to prevent future crashes of this type.
* Fixed a performance regression introduced by #36244.
Fixes#63718, probably other crashes too.
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".
- `LIBC_FILEIO_ENABLED` wasn't defined anywhere, even in _other platforms_.
- `NO_NETWORK` is also never defined. It probably isn't enough anyway to
disable network APIs in the current codebase.
- `UNIX_SOCKET_UNAVAILABLE` is never defined in this code but used by some
other platforms, clarify that.
- `NO_STATVFS` can be removed as Android supports it since API level 19,
which is our current min SDK level. It's also only used for
`DirAccessUnix::get_space_left()` which is anyway overridden by
`DirAccessJAndroid::get_space_left()` so it shouldn't make a difference.
* Fixed documentation for `DirAccess.get_space_left()`.
- `NO_FCNTL` is likely also a remnant of early Android days, in current NDK
r23 it seems to be available. Also cleaned up unused `fcntl.h` includes.
- `NO_ALLOCA` is never defined, and we use alloca in many places now.
With the introduction of Scene Unique Nodes, `is_unique_in_owner`, "Unique Name in Scene" and other descriptions related to the feature, the second parameter of add_child() and add_simbling() could be misunderstood to be related, at first glance.
- 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.
The name was confusing as this signal is emitted around the same time as
`tree_exiting` and `NOTIFICATION_EXIT_TREE`, i.e. while the child node is
still in tree.
Fixes#59210.
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
These typedefs don't save much typing compared to the full `Ref<Resource>`
and `Ref<RefCounted>`, yet they sometimes introduce confusion among
new contributors.
Removes custom_multiplayer from Node.
MultiplayerAPI overrides are now set at SceneTree level, and apply to
whole branches.
Impact on performance when using only the default multiplayer or
overriding it is minimal, the use of branches can likely be further
optimized by caching nodes and relevant MultiplayerAPI IDs.
The new name contrasts it better with `find_parent`, and makes it clear
that it only matches child/descendant nodes.
Also rename `find_nodes` to `find_children` accordingly.
Implements https://github.com/godotengine/godot-proposals/issues/4096
* Nodes can be marked unique to the scene in the editor (or via code).
* Unique nodes can be accessed via the **%** prefix at any point in the path. From that point in the path (depending on whether the scene of the path is), the unique node will be fetched.
* Implementation is very optimal, as these nodes are cached.
Type emit_signal exposed method return type
set UndoRedo add_do_method and add_undo_method exposed return void
Set TreeItem::_call_recursive_bind returns void
Set _rpc_bind and _rpc_id_bind returns void in Node
Set _call_group and _call_group_flags method returns void in SceneTree
Set godot-cpp-test CI flag to false
* Very old macros from the time Godot was created.
* Limited arguments to 5 (then later changed to 8) in many places.
* They were replaced by C++11 Variadic Templates.
* Renamed methods that take argument pointers to have a "p" suffix. This was used in some places and not in others, so made it standard.
* Also added a dereference check for Variant*. Helped catch a couple of bugs.
Changed 'find_node' to 'find_nodes' which now returns an 'TypedArray<Node>', as well as Added a 'type' parameter to match against specific node types, which supports inheritance.
Initial implementation of the MultiplayerReplicationInterface and its
default implementation (SceneReplicationInterface).
New MultiplayerSpawner node helps dealing with instantiation of scenes
on remote peers (e.g. clients).
It supports both custom spawns via a `_spawn_custom` virtual function,
and optional auto-spawn of known scenes via a TypedArray<PackedScenes>
property.
New MultiplayerSynchornizer helps synchronizing states between the local
and remote peers, supports both sync and spawn properties and is
configured via a `SceneReplicationConfig` resource.
It can also sync via path (i.e. without being spawned by a
MultiplayerSpawner if both peers has it in tree, but will not send the
spawn state in that case, only the sync one.
-Allows more fine grained notifications (hence better performance) than using the global scene tree signals (node added and removed).
-Required for #55950
- Regarding preservation of owner, `free()` and `remove_child()` now behave the same: owner is kept during `tree_exiting` signal and `null` during `tree_exited`.
- `tree_exited` is emitted in the same order as `tree_exiting`.
- Superfluous code to handle cancelation of ownership is removed.
`core` and `scene` shouldn't depend on `editor`, so they can't query this style
setting in `get_argument_options`. But we can handle it after the fact in
GDScript's completion code.
Also cleans up a couple extra unused invalid includes in `core`.
Removes _networking_ prefix from some methods and members, now that multiplayer has been largely moved out of Node and SceneTree and is seperated into its own set of classes.
Move multiplayer classes to "core/multiplayer" subdir.
Move the RPCConfig and enums (TransferMode, RPCMode) to a separate
file (multiplayer.h), and bind them to the global namespace.
Move the RPC handling code to its own class (RPCManager).
Renames "get_rpc_sender_id" to "get_remote_sender_id".
Prevent the root node to be set to PROCESS_MODE_INHERIT, since it causes
undefined behavior.
Fix a case where the process owner node is wrongly set to the direct
parent instead of the proper node.
Add errors for all unhandled cases.
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.
* `_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.
* 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.
`PackedScene`s can be configured to be spawnable via a new
`MultiplayerAPI.spawnable_config` method.
They can be configured either to be spawned automatically when coming
from the server or to always require verification.
Another method, `MultiplayerAPI.send_spawn` lets you request a spawn on
the remote peers.
When a peer receive a spawn request:
- If it comes from the server and the scene is configured as
`SPAWN_MODE_SERVER`:
- Spawn the scene (instantiate it, add it to tree).
- Emit signal `network_spawn`.
- Else:
- Emit signal `network_spawn_request`.
In a similar way, `despawn`s are handled automatically in
`SPAWN_MODE_SERVER`.
In `SPAWN_MODE_SERVER`, when a new client connects it will also receive,
from the server all the spawned (and not yet despawned) instances.
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.
This is part of ongoing work to optimize GUI and the editor.
New property disable_mode to set different behaviors:
Remove: remove from physics simulation
MakeStatic: change body mode to static (doesn't affect area and soft body)
KeepActive: do nothing
Extra change:
Handle disable/enable node state with specific notifications, in order
to differentiate global pause from disabled nodes.
