I wanted to add this tool for years and always forget. This command line option:
```
$ godot.exe -e --debug-canvas-item-redraw
```
Allows to see when a canvas item is redrawn. This helps find out if something
in the UI is refreshing in a way it should not. Examples as such:
* Signals causing more of the UI to redraw.
* Container resizing causes more UI elements to redraw.
* Something using a timer is redrawing all time time, which can go unnoticed.
To my surprise, the editor UI is redrawing very efficiently. There is some
weird stuff with the scene tabs, redrawing when the inspector changes but most
things for the most part are fine.
The issue was caused because the running game pid was not set, and thus had a value of `0`. When trying to stop the running game, the `EditorRun::stop()` logic would kill the process with pid 0, which on Android corresponds to the running app's own process, thus causing the editor to crash.
This issue did not happen on Godot 3 because pid with value of `0` are not considered valid.
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
* Allows running the game in "movie writer" mode.
* It ensures entirely stable framerate, so your run can be saved stable and with proper sound (which is impossible if your CPU/GPU can't sustain doing this in real-time).
* If disabling vsync, it can save movies faster than the game is run, but if you want to control the interaction it can get difficult.
* Implements a simple, default MJPEG writer.
This new features has two main use cases, which have high demand:
* Saving game videos in high quality and ensuring the frame rate is *completely* stable, always.
* Using Godot as a tool to make movies and animations (which is ideal if you want interaction, or creating them procedurally. No other software is as good for this).
**Note**: This feature **IS NOT** for capturing real-time footage. Use something like OBS, SimpleScreenRecorder or FRAPS to achieve that, as they do a much better job at intercepting the compositor than Godot can probably do using Vulkan or OpenGL natively. If your game runs near real-time when capturing, you can still use this feature but it will play no sound (sound will be saved directly).
Usage:
$ godot --write-movie movie.avi [scene_file.tscn]
Missing:
* Options for configuring video writing via GLOBAL_DEF
* UI Menu for launching with this mode from the editor.
* Add to list of command line options.
* Add a feature tag to override configurations when movie writing (fantastic for saving videos with highest quality settings).
Note: This PR also changes the port of the GDScript Language Server from 6008 to 6005. This opens enough ports above the debug port (6007) for this change to be useful.
This can be used to tell Godot to run an executable that will run Godot
rather than running Godot directly. This is useful to make Godot start
on the dedicated GPU when using a NVIDIA Optimus setup on Linux:
`prime-run %command%`
The `editor/run/main_run_args` setting declaration was moved to make it
visible in the ProjectSettings documentation.
Happy new year to the wonderful Godot community!
2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.
We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)
Here's to a great year 2021 for all Godot users 🎆
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.
This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.
There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).
Part of #33027.
Happy new year to the wonderful Godot community!
We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.
Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.
