* NOTIFICATION_MOVED_IN_PARENT makes node children management very inefficient.
* Replaced by a NOTIFICATION_CHILD_ORDER_CHANGED (and children_changed signal).
* Most of the previous tasks carried out by NOTIFICATION_MOVED_IN_PARENT are now done not more than a single time per frame.
This PR breaks compatibility (although this notification was very rarely used, even within the engine), but provides an alternate way to do the same.
Allows a non-interpolated particle system to closely follow an interpolated target without tracking ahead of the target, by performing fixed timestep interpolation on the particle system global transform, and using this for emission.
Adds optional hierarchical culling to the 2D rendering (within VisualServer).
Each canvas item maintains a bound in local space of the item itself and all child / grandchild items. This allows branches to be culled at once when they don't intersect a viewport.
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".
Backported from #70885.
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.
(cherry picked from commit 3e6de687b8)
Exposes the "interpolated" flag on nodes via a property, physics_interpolation_mode.
Mode can be INHERIT, OFF and ON. This makes it easy to turn off interpolation for nodes in the editor, versus via code.
Adds fixed timestep interpolation to the visual server.
Switchable on and off with project setting.
This version does not add new API for set_transform etc, when nodes have the interpolated flag set they will always use interpolation.
-Allows more fine grained notifications (hence better performance) than using the global scene tree signals (node added and removed).
-Required for #55950
(cherry picked from commit fbd9599b04)
- Regarding preservation of owner, `free()` and `remove_child()` now behave the same: owner is kept during `tree_exiting` signal and `null` during `tree_exited`.
- Superfluous code to handle cancelation of ownership is removed.
- Mention the origin of the `get_node()` call.
- Mention whether the attempted path is absolute or relative.
See #46214.
