The signal was emitted right as the node was being disposed of. Since
the connection was deferred, the receiving method received an already
freed pointer. Instead, we listen to the text_changed signal and keep
record of the edited text which we then use to update node name when
the LineEdit goes out of focus.
This allows using generic Godot collections as type arguments for other
generic Godot collections. This also allows generic Godot collections
as parameter or return type in dynamic Callable invocations.
We aim to make the C# API reflection-free, mainly for concerns about
performance, and to be able to target NativeAOT in refletion-free mode,
which reduces the binary size.
One of the main usages of reflection still left was the dynamic
invokation of callable delegates, and for some time I wasn't sure
I would find an alternative solution that I'd be happy with.
The new solution uses trampoline functions to invoke the delegates:
```
static void Trampoline(object delegateObj, NativeVariantPtrArgs args, out godot_variant ret)
{
if (args.Count != 1)
throw new ArgumentException($"Callable expected 1 arguments but received {args.Count}.");
string res = ((Func<int, string>)delegateObj)(
VariantConversionCallbacks.GetToManagedCallback<int>()(args[0])
);
ret = VariantConversionCallbacks.GetToVariantCallback<string>()(res);
}
Callable.CreateWithUnsafeTrampoline((int num) => "Foo" + num, &Trampoline);
```
Of course, this is too much boilerplate for user code. To improve this,
the `Callable.From` methods were added. These are overloads that take
`Action` and `Func` delegates, which covers the most common use cases:
lambdas and method groups:
```
// Lambda
Callable.From((int num) => "Foo" + num);
// Method group
string AppendNum(int num) => "Foo" + num;
Callable.From(AppendNum);
```
Unfortunately, due to limitations in the C# language, implicit
conversions from delegates to `Callable` are not supported.
`Callable.From` does not support custom delegates. These should be
uncommon, but the Godot C# API actually uses them for event signals.
As such, the bindings generator was updated to generate trampoline
functions for event signals. It was also optimized to use `Action`
instead of a custom delegate for parameterless signals, which removes
the need for the trampoline functions for those signals.
The change to reflection-free invokation removes one of the last needs
for `ConvertVariantToManagedObjectOfType`. The only remaining usage is
from calling script constructors with parameters from the engine
(`CreateManagedForGodotObjectScriptInstance`). Once that one is made
reflection-free, `ConvertVariantToManagedObjectOfType` can be removed.
* When there's nothing to collide with:
* Place the new scene on XZ plane when possible.
* When the camera does not point toward the XZ plane or the
intersection is too far away, place the new scene on a plane that
is in front of the camera and parallel to the frame.
* Fixes positioning when in orthogonal view.
* Place on physical collision point or the XZ plane when possible.
* Otherwise, place it on the plane in front of the camera as if the
camera was perspective.
* Makes use of snap settings when placing the new scene.
Fix for 3D-physics processing:
- with enabled input_capture_on_drag now report correct position and
normals in _input_event
- mouse_enter and mouse_exit signals are emitted when the mouse cursor
leaves the visible area of the 3D-object, independently of pressed mouse
button or input_capture_on_drag
- make sure that collision input events are sent in the right order with
respect to mouse_enter and mouse_exit signals
It covers additional selections of different words, as well manually adding a cursor in between and selecting the next occurrence. The previous test also was outdated in regards of not testing the implicit call to `select_word_under_caret` made by `add_selection_for_next_occurrence` in case there's no selection.
Fix that Windows receive WINDOW_EVENT_MOUSE_EXIT on startup.
When moving the mouse cursor from one window to a different one, make sure that the first window receives the WINDOW_EVENT_MOUSE_EXIT event before the second window receives the WINDOW_EVENT_MOUSE_ENTER event.
Send Mouse-Move events also for Windows, that are currently not focused.
For determining the currently hovered window, consider not just the currently focused window, but also other windows.
Send mouse move events to focused window instead of hovered window.
