Settings that aren't within a subsection are difficult to reach when
other settings do have a subsection.
This also adds documentation for the project setting.
Reporting rest collision information is needed for move_and_collide and
move_and_slide so floor detection can be done properly, but in the case
of just testing the motion for collision, it makes sense to return false
if the body is able to move all along the path without being stopped.
Updated the logic in test_move and clarified the documentation for
test_move and move_and_collide.
In all physics servers, body_get_direct_state() now silently returns
nullptr when the body has been already freed or is removed from space,
so the client code can detect this state and invalidate the body rid.
In 2D, there is no change in behavior (just no more errors).
In 3D, the Bullet server returned a valid direct body state when the
body was removed from the physics space, but in this case it didn't
make sense to use the information from the body state.
When comparing different graphics settings or optimizations,
this makes precise measurements and frametime comparisons easier.
This also makes the editor FPS display use `pad_decimals()`
for consistency with the implementation in `master`.
The hash symbol creates spurious issue references on GitHub if
the message is posted outside a code block, which means some issues
have a lot more references than originally intended.
Async. compilation via ubershader is currently available in the scene and particles shaders only.
Bonus:
- Use `#if defined()` syntax for not true conditionals, so they don't unnecessarily take a bit in the version flagset.
- Remove unused `ENABLE_CLIP_ALPHA` from scene shader.
- Remove unused `PARTICLES_COPY` from the particles shader.
- Remove unused uniform related code.
- Shader language/compiler: use ordered hash maps for deterministic code generation (needed for caching).
- Locking nodes can now be done by pressing Ctrl + L, and unlocking with
Ctrl + Shift + L.
- Grouping nodes is now done by pressing Ctrl + G, and ungrouping with
Ctrl + Shift + G (similar to Inkscape).
- Toggling the grid is now done by pressing the `#` key
(also similar to Inkscape). This change was needed as Ctrl + G
now groups selected nodes.
Different shortcuts are used for the lock/unlock and group/ungroup
actions, so that the shortcuts are idempotent.
This makes the Linear and Cubic icons in particular easier to
distinguish from each other.
The Cubic interpolation icon's curve was also changed to be
more distinguishable from the Linear icon's curve.
For octahedral compressed normals/tangents, we use vec4 in the shader
regardless of whether a normal/tangent does/doesn't exist
For the case where we only have a normal vector, we need to specify that
there are only two components being used when calling glVertexAttrib
Before we would always specify that there were 4 components, and used
offsets to determine where in the vertex buffer to read data from but
this doesn't work on all platforms
