This patch adds ability to include external, user-defined C++ modules
to be compiled as part of Godot via `custom_modules` build option
which can be passed to `scons`.
```
scons platform=x11 tools=yes custom_modules="../project/modules"
```
Features:
- detects all available modules under `custom_modules` directory the
same way as it does for built-in modules (not recursive);
- works with both relative and absolute paths on the filesystem;
- multiple search paths can be specified as a comma-separated list.
Module custom documentation and editor icons collection and generation
process is adapted to work with absolute paths needed by such modules.
Also fixed doctool bug mixing absolute and relative paths respectively.
Implementation details:
- `env.module_list` is a dictionary now, which holds both module name as
key and either a relative or absolute path to a module as a value.
- `methods.detect_modules` is run twice: once for built-in modules, and
second for external modules, all combined later.
- `methods.detect_modules` was not doing what it says on the tin. It is
split into `detect_modules` which collects a list of available modules
and `write_modules` which generates `register_types` sources for each.
- whether a module is built-in or external is distinguished by relative
or absolute paths respectively. `custom_modules` scons converter
ensures that the path is absolute even if relative path is supplied,
including expanding user paths and symbolic links.
- treats the parent directory as if it was Godot's base directory, so
that there's no need to change include paths in cases where custom
modules are included as dependencies in other modules.
(cherry picked from commit a96f0e98d7)
The crosshair makes freelook navigation a bit easier, while making it
clearer that it's possible to select nodes by clicking while in
freelook mode.
The crosshair is only displayed while in freelook mode.
It uses an icon designed to be visible on any background.
- Add icons to the up/down bandwidth LineEdits for better
visual grepping.
- Make bandwidth LineEdit texts more prominent when data is being
received/emitted.
- Add more spacing between the up and down bandwidth LineEdits.
- Initialize the bandwidth texts using `set_bandwidth()` to ensure
consistency with the actual bandwidth texts once the profiler
is started.
- Fix icon colors when switching from a dark theme to a light theme
and vice versa.
- Add missing `EDSCALE` constants for hiDPI scaling.
The arrow is now displayed at the left to be consistent with
other places where folding is used. The arrow icons used are now
consistent with the rest of the editor. The `arrow_up` icon is
no longer used anywhere, so it was removed.
Additional spacing was also added for a better visual appearance.
- Add new handle icons for path/polygon editors
- Add smooth path point icons and curve tangent icons
- Use a gray color for tangent lines in the Path2D and Path editors
- Use antialiasing for Path2D lines
Keyframe SVG icons are now 10×10 instead of 8×8 (except for
Bezier-related icons). This makes them easier to select
since the empty space is part of the clickable area.
Selected keyframes are now also visually larger to make them
easier to distinguish from unselected keyframes.
This closes#27276.
This icon was likely added to be used in the renderer selection
dropdown, but now that the GLES2 and GLES3 icons have been removed
in favor of just using text, it'll probably never be used.
The functionality is similar to how `doc_classes` are retrieved per module.
The build system will search for custom icons path defined per module via
`get_icons_path()` method in `config.py` or default icons path.
If such paths don't exist, only the editor's own icons will be built.
Most module icons were moved from editor/icons to respective modules.
Godot 2.1 and 3.0 had this feature but it was lost in the rewrite
of the animation editor in 3.1.
Drop unused KeyValid icon, since all valid keys now have a custom
type icon.
