The parent `_validate_property()` wasn't called, which led to shadow
properties being visible even if shadows were disabled on a
DirectionalLight3D node.
* Made the Basis euler orders indexed via enum.
* Node3D has a new rotation_order property to choose Euler rotation order.
* Node3D has also a rotation_mode property to choose between Euler, Quaternion and Basis
Exposing these modes as well as the order makes Godot a lot friendlier for animators, which can choose the best way to interpolate rotations.
The new *Basis* mode makes the (exposed) transform property obsolete, so it was removed (can still be accessed by code of course).
Some split distance properties are unused depending on the
current shadow mode. Also, Blend Splits can only be used if the shadow
mode is PSSM 2 Splits or PSSM 4 Splits.
This also moves the Fade Start property to be located after the
split properties. This avoids intertwining "conditional" properties
with a property that's always available.
Fixes the SHADOW_CASTING_SETTING_OFF setting in
GeometryInstance3D and the "shadows_disabled" render
mode in spatial materials, which were not working
before.
This prevents errors when encountering options which have been defined in newer
versions of clang-format, and are invalid in the YAML for the old version.
Bump minimum supported clang-format version to 12 (where `--Wno-error=unknown`
was added).
Use clang-format 12 on CI (13 is not available yet on the Ubuntu 20.04 images).
Mapping and other "abstract base classes" were moved after python 3.3 from collections to collections.abc
Python 3.3 is long gone and a newer version of python won't support this code.
When emitting stops CPUParticles3D::_set_redraw(bool p_redraw) will set that value to 0 so when you change the amount after that it will actually not update correclty.
This fixes an issue where if it was not emitting when the scene loaded and it start after that the amount is not reflected correclty. This also happened when you checked out the box for emitting in the editor, changed the value of amount and then checked on the box for emitting. With this change if it is emitting during the change it does interrupt the previous particles when you change. The amount and the emit starts from beginning but that is to be expected on an amount of particles change.
