We now cache the Node*<>TreeItem* mapping in the SceneTreeEditor. This
allows us to make targeted updates to the Tree used to display the scene
tree in the editor.
Previously on almost all changes to the scene tree the editor would
rebuild the entire widget, causing a large number of deallocations an
allocations. We now carefully manipulate the Tree widget in-situ saving
a large number of these allocations.
In order to know what Nodes need to be updated we add a
editor_state_changed signal to Node, this is a TOOLS_ENABLED,
editor-only signal fired when changes to Node happen that are relevant
to editor state.
We also now make sure that when nodes are moved/renamed we don't check
expensive properties that cannot contain NodePaths. This saves a lot of
time when SceneTreeDock renames a node in a scene with a lot of
MeshInstances. This makes renaming nodes go from ~27 seconds to ~2
seconds on large scenes.
SceneTreeEditor instances will now also not do all of the potentially
expensive update work if they are invisible. This behavior is turned off
by default so it won't affect existing users. This change allows the
editor to only update SceneTreeEditors that actually in view. In
practice this means that for most changes instead of updating 6
SceneTreeEditors we only update 1 instantly, and the others only when
they become visible.
There is definitely more that could be done, but this is already a
massive improvement. In complex scenes we see an improvement of 10x,
things that used to take ~30 seconds now only take 2.
This fixes#83460
I want to thank KoBeWi, TokisanGames, a-johnston, aniel080400 for
their tireless testing. And AeioMuch for their testing and providing a
fix for the hover issue.
* Replaces `find(...) != -1` with `contains` for `String`
* Replaces `find(...) == -1` with `!contains` for `String`
* Replaces `find(...) != -1` with `has` for containers
* Replaces `find(...) == -1` with `!has` for containers
* Disabled 2D navigation tests as they do not work
* Disabled tests for primitive meshes
* Unbound some `Mesh` methods that rely on 3D resources
* Unexposed `World3D` as it depends on physics (and isn't useful)
* Unexposed some `Viewport` vrs related properties that had unexposed
methods
This cleans up a few more cases of uint32_t->uint64_t
Importantly this fixes an edge case in the axis-angle compression by
using the pre-existing Basis methods instead
This allows Godot to automatically compress meshes to save a lot of bandwidth.
In general, this requires no interaction from the user and should result in
no noticable quality loss.
This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.
Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.
* This should optimize GDScript function calling _enormously_.
* It also should simplify the GDScript VM considerably.
NOTE: GDExtension calling performance has most likely been affected until going via ptrcall is fixed.
