Currently we rely on some undefined behavior when Object->cast_to() gets
called with a Null pointer. This used to work fine with GCC < 6 but
newer versions of GCC remove all codepaths in which the this pointer is
Null. However, the non-static cast_to() was supposed to be null safe.
This patch makes cast_to() Null safe and removes the now redundant Null
checks where they existed.
It is explained in this article: https://www.viva64.com/en/b/0226/
This was broken in #7438 where the ordering of scaling in Basis::scale() was fixed, but this line of code (which relied on the incorrect behavior) wasn't updated correctly.
Fixes#9894.
-Added new 3D stream player node
-Added ability for Area to capture sound from streams
-Added small features in physics to be able to properly guess distance to areas for sound
-Fixed 3D CollisionObject so shapes are added the same as in 2D, directly from children
-Fixed KinematicBody API to make it the same as 2D.
-Added default environment editor setting
-Added environment created by default in new projects
-Removed default light and ambient from spatial editor, to make the editor more PBR compliant
- Fix movement input affecting all viewports even when clicking outside
- Freelook up movement is now relative
- Prevent tool shortcut conflict when moving
- De-hardcode tool shortcuts (select, move, rotate, scale, wireframe)
- Movement speed depends on zoom distance (like panning)
- Mouse wheel controls speed (Blender-style) due to above point
- Added zoom distance indicator, hides after short delay
- Triggered by holding RMB
- Can look around in FPS style
- Can move with WASD
- Movement speed accelerates over time
- Can multiply speed with a modifier key to go faster or slower
- Configurable in editor settings and shortcuts
Enabled by default as in Blender, but can be disabled separately for 2D & 3D;
the core functionality is in Input so this could be reused or even exposed to scripts in the future
I can show you the code
Pretty, with proper whitespace
Tell me, coder, now when did
You last write readable code?
I can open your eyes
Make you see your bad indent
Force you to respect the style
The core devs agreed upon
A whole new world
A new fantastic code format
A de facto standard
With some sugar
Enforced with clang-format
A whole new world
A dazzling style we all dreamed of
And when we read it through
It's crystal clear
That now we're in a whole new world of code
The other subfolders of tools/ had already been moved to either
editor/, misc/ or thirdparty/, so the hiding the editor code that
deep was no longer meaningful.
