We should make guides for these softwares on how to effectively use them to generate assets usable in this project.

1920x1080 is large. It would be better to halve what's in the game.project file so it's 960x540.

Reasoning for this is that not all users have large screens and the default display size can cause issues for them if they are running on a PC.

If a larger initial view size is desired it could be set with DefOS based on user configs.

Could add a tiny bit of input smoothing as an option, just because it generally can feel nicer than raw input.

I used SideFX Houdini to prepare all the content included in Scene3D. It's time to release HDAs that I developed for that task.

• Learn how to release open-source HDAs - they can be in binary/directory formats and should work with Houdini for indies.
• Clean up Python code.
• Write documentation.
• Release.

Describe the bug
Current, the code has lots of vmath.lerp calls. It assumes that the user has the constant 60 FPS.

To Reproduce
Run the examples on higher or lower framerates.

Expected behavior
The code should be deltatime-independent.

Additional context (optional)
Using lerp with delta-time

FPS games are a common desire to make. We could make a Quake style level with TrenchBroom and find a good workflow for that.

Example would need first person view (maybe with unique models), crosshair stuff, shooting, reloading, maybe multiple guns, maybe grenades. Maybe an enemy too with a body+head hitbox for instant kills.

Could also do a 3rd person shooter example in the style of Fortnite.

Destiny 2 can be played for free on Stadia to reference how sparrows behave.

One feature that's nice about their version is that mouse can be used for turning in a precise way. This would be the main reasoning in adding this vehicle type as an example.

Example of an arcadey kart style racing controller would be useful. There are important features like jumping / sliding / powerups that would be useful to include examples for.

Follow camera does not currently avoid obstacles.

Follow camera could raycast to the player and try to avoid obstacles between it and the player in a smart way.

Describe the content you'd like
I'd like to use 3D assets from Kenney: https://kenney.nl/assets?q=3d
They are available for free and can be used commercially.

The idea is to:

1. Mass-convert all the assets from Kenney and put them into a separate repository (defold-scene3d-kenney). The repo will be huge.
2. Wrap all models into game objects that will have the same components as Scene3D's icon, i.e. mesh, collisionobject, script.
3. Render previews for all models and put them in repo's README to know what we have.

I think it'll be fun to be able to put any Kenney's 3D put into your scene, modify collision, material, animation and make a game right from the Defold IDE in a "zero-coding" manner.

Describe alternatives you've considered (optional)
It's time-consuming to dig in Kenney's asset library and put them in your scene because you do that one by one.

Describe the bug
When turning the vehicle, jittering can be observed if the display frequency rate is beyond the physics

To Reproduce
Steps to reproduce the behavior:

1. Open demo on display faster than 60hz
2. Accelerate and turn
3. See Jittering

Expected behavior
Vehicle should not be jittering while turning.

Hardware (optional)

• Device: Lenovo Laptop with i5 processor
• OS: windows 11

Additional context (optional)
Setting the engine display rate to 60 inside the game project file fixes this issue

These would be useful to have as size references.

Block game (like Infiniminer / Minecraft) example project.

• Multiple block types
• Add block / remove block
• Block collision
• AI pathing example (dumb raycasts)
• Basic combat?
• Chunking?
• Dynamic geometry optimization?

What do you think about adding this to the project?

So along with that would want some editor scripts and some guides for building / adding new assets properly.

Do you already have an asset generation workflow?

Describe the content you'd like
A simple example of the steps to install scene3d into one's project (similar to other extensions)

Describe alternatives you've considered (optional)
Bruteforcing implementation and reading the code in order to guess at how to use it

Additional context (optional)
I am not a C++ developer, so I cannot derive too much meaning from the internal core files such as extension.cpp

Describe the content you'd like
That would be nice to add one of existing on-screen controllers into the example to be able to play it on mobile.

Describe the bug
Hello when I tried camera3d, it is throwing error when rotation X is exactly -90. I tried to debug it and it looks like Error is in render3d.lua . viewport.view_right has vector3 with nan values.

To Reproduce
Steps to reproduce the behavior:

4. Run the game

Expected behavior
Show sphere

Hardware (optional)

• OS: Windows
• Version: in project from this URL https://github.com/indiesoftby/defold-scene3d/archive/main.zip

Additional context (optional)
Error:

ERROR:SCRIPT: scene3d/render/render3d.lua:98: argument #1 contains one or more values which are not numbers: vmath.vector3(nan, nan, nan)
stack traceback:
  [C]:-1: in function cross
  scene3d/render/render3d.lua:98: in function view_direction
  scene3d/camera/camera3d.script:32: in function update_render
  scene3d/camera/camera3d.script:70: in function <scene3d/camera/camera3d.script:68>

Editor scripts is a great idea - we should add another issue to discuss it. Something like:

Align selected objects
Rename selected objects
etc...

#7 (comment)

Should compile a list of more useful ideas here / ask the community what 3D related features we could add as editor scripts that would be useful.

How the asset should look (looks in editor)

How it looks in engine

@JCash

To create 3d hyper-casual games in which control is carried out using "hold and drag", it is necessary that on each device, regardless of the screen resolution, the mouse must travel the same distance in world coordinates, this requires a function or method for translating screen coordinates into world coordinates, which is currently missing or not implemented.

Describe the content you'd like
A T-pose model with a couple of animations like idle, walk, run, jump.

Need some kind of workflow for making/using patches of terrain which can be shaped in some tool and have its geometry used for collisions.
