Update most demos for Godot 4.0.beta10

[Calinou]

The HDR for 2D demo was renamed to Glow for 2D as autoexposure can no longer be used in 2D in 4.0.

The SDF font demo was renamed to MSDF font to denote that multi-channel distance field fonts are now used.

The OpenSimplexNoise demo was renamed to Noise Viewer as it now uses FastNoiseLite.

Various demos have received small improvements along the way (mainly cosmetic changes or usability improvements):

• All demos now use physical key inputs, so that non-QWERTY keyboard layouts work out of the box.
• GUI-only demos have low processor mode enabled and V-Sync disabled, for low input lag while keeping resource usage low. Tearing caused by the lack of V-Sync is usually not noticeable in GUI-only demos.
• In some demos, physics FPS was increased to 120 to improve smoothness on high refresh rate displays and decrease input lag. Demos have simple physics calculations compared to full-blown projects, so this change should be affordable on lower-end devices too.
• Glow for 2D demo now features a toggleable glow map (lens dirt effect).
• 2D particles demo now features turbulence, subemitters, collision and global coordinates animation examples (particles + PathFollow2D). Glow can also be toggled.
• Truck Town now features a race track on the outside of the town, built using CSGPolygon3D + Path3D.
• Truck Town now has a large floor plane that extends past the city for a better appearance. It can also be driven on if you need to see how vehicles behave on a large flat plane.
• Truck Town now features engine and impact sounds, blob shadows for cars, exhaust particles and dynamic FOV based on speed. These changes don't require much additional code, but improve the feel of the demo a lot when put together. The speedometer's color changes depending on speed thanks to a Gradient resource, and the unit can be changed by pressing U or Select as an alternative to clicking the button (implemented using BaseButton's shortcut property).
• Truck Town has revised textures (AI upscaled to 2×, grass color tweaked to be more pleasing to the eyes). The level geometry now features smoother terrain.
• Truck Town's UI is now keyboard and gamepad-friendly. A title label was also added.
• Platformer 3D now features a reset button (R) that is automatically used when falling off the map, like Kinematic Character 3D. Platformer 3D also has increased gravity and jump height for better jump feeling. Jump height can now be reduced by releasing the jump key mid-air.
• The Platformer 3D stage was extended to make more areas reachable.
• Bullets shot by the player in the Platformer 3D demo now emit light. The character also casts a blob shadow using a Decal node, and its material fades out with dithering if it gets too close to the camera (for better scene visibility).
• The number of coins collected is now kept track of in Platformer 3D, with the number displayed above the player character in 3D space (diegetic UI).
• RigidBody Character 3D now uses orange-red textures instead of purple to visually distinguish it from Kinematic Character 3D.
• RigidBody Character 3D now uses a ShapeCast3D instead of a RayCast3D to detect whether the player is able to jump. Compared to a RayCast3D which is infinitely thin, this allows for more reliable checking if the player is standing over an edge or corner.
• Voxel demo now features crouch camera smoothing.
• Voxel and Dynamic Split Screen demos now feature smooth physics friction for the player controller.
• Window Management demo now features a transparent window toggle, as well as confined and confined + hidden mouse mode. Screen refresh rate is also displayed.
• Various additional cosmetic tweaks.
• Mic Record demo now has an "Open User Folder" button. Print output formatting on playback was also improved.
• Audio Generator demo now features a volume slider and a generated frequency slider.
• 3D Graphics Settings demo now features settings for FSR sharpness, shadow resolution, shadow filtering and model quality (mesh LOD). Preset buttons were also added.

Not planned to be tackled in this PR

These should be updated in separate PRs: https://github.com/godotengine/godot-demo-projects/pulls?q=is%3Apr+is%3Aopen+sort%3Aupdated-desc+label%3Aupdate

• mobile/ demos
• mono/ demos
• networking/ demos

Future TODOs

• Add shadow resolution, shadow filter quality and depth of field settings to 3D Graphics Settings demo.
• Update screenshots for all demos.
• Check Camera2D settings in all demos to match the new default window size.

Footnotes

1. The update was done in https://github.com/godotengine/godot-demo-projects/pull/776. This PR includes some cosmetic changes to the loading/ demos. ↩ ↩² ↩³

[Calinou]

This is now ready for review, even though not all demos were updated to 4.0 as part of this PR. We can do that in future pull requests.

Please test all demos locally and report any issues you may encounter 🙂

Instructions

• Download 4.0.beta10 (standard; Mono is supported but not required here).
• To avoid confusion with other projects and official demos, remove all projects from your project list, or use the self-contained mode to use an isolated project list from your usual project list.
• Download the PR fork's branch: https://github.com/Calinou/godot-demo-projects/archive/refs/heads/update-demos-4.0beta2.zip
• Use the project manager's Scan button to import all demos at once.
• Use the Edit button to import a demo in the editor, then press F5 to run it. It should work immediately with no further configuration.

Probably won't have time to do in depth review or testing, but I believe it's worth merging sooner than later, and catch potential issues once more users try the updated demos.

Hi, I have taken some time to go through the demos listed above and test them on Godot 4.0b10. Projects without comments worked fine as far as I could tell. I got a lot of "Load failed due to missing dependencies" errors when first opening projects, but they all seemed to be fine after pressing the "Open anyway" button. Not sure if that is Godot 4 bug or something related to the projects in question, I would have to check if any diff was caused by pressing the "Open anyway" button. I've probably included some things here that are just noise, but I've tried to stick to debugger breaks and errors.

I'd be happy to provide further information or test more if there are any points here that are unexpected or platform specific.

Computer specs:

Mac OS X Ventura (13.1)
2,7 GHz Quad-Core Intel Core i7
Intel Iris Plus Graphics 655 1536 MB
16 GB 2133 MHz LPDDR3

Results:

• plugins
  • Unable to load addon script from path: 'res://addons/custom_node/heart_plugin.gd'. This might be due to a code error in that script. Disabling the addon at 'res://addons/custom_node/plugin.cfg' to prevent further errors.
  • Everything seemed to work fine though.
• misc/pause
  • The dropdown only works when the button reads "Unpause". Unclear if this was intended, but after a quick look I couldn't find what may cause that. Perhaps process_mode.gd also needs to use process_mode = Node.PROCESS_MODE_ALWAYS like pause_button.gd does?

  • noise_viewer.gd:26 Integer division, decimal part will be discarded.
• misc/window_management

Thanks for testing 🙂

I'll merge this following Akien's approval. Fixes can be applied to future pull requests to keep changes easy to review.
