Originating from a use case by @trsh when dealing with chunks generated by the fracturing system.

the docs suck and I cant find the damn panel to draw with voxels. I've read all of the documentation and watched all videos i can find on the engine and nothing. how the hell do i use it? i cant even make a fucking scene

Hello! IOLITE engine does not start because it crashes.
The CPU and GPU meet the minimum system requirements, even the optimal ones. My computer components:

Video card: GeForce GTX 1080 Ti
Processor: Intel Core i7-8700K
RAM size: 16 GB
OS: Windows 10

The latest drivers are installed (Vulkan is built-in, it seems). I even tried the "minimal" installation.
Besides, I can't find the log
Screenshot:

We could have a separate physics tick, that ticks at same time as engine physics tick to do physics stuff before rendering.

it would be great to include some license information for the public parts as well for the engine?

When I try to open IOLITE nothing happens. It would be appreciated if there is a fix to this. Thanks

Editor:

Bounciness and drag factor for particles
The eye in UI, for hiding, currently doesn't work for particle effect

API:

From discord discussion: The interface is a little barebones at the moment. I will expose all the available functionality

And ability to define some thresholds for that.

When the engine is installed into C:\ProgramFiles the sample project is also installed in the same location. When trying to create a new world it probably tries writing to disk (which doesn't work without admin) and then crashes the engine.

Reproduction steps:

1. Download iolite-v0.1.21
2. Download sample projects
3. Copy over sample projects and add to app_metadata.json data_sources
4. Run the editor and open, for example, 'sample_physics' world
5. Open script 'iolite-v0.1.21\sample_physics\media\scripts\gameplay_physics.lua
6. Open console F2
7. Change script
8. Nothing show up in console
9. Run game and the changes have no effect
10. Run game second time and the changes have effect

OS: Windows 11 x64

Just want to keep track for this

When I have a world loaded from a different directory other than the default (btw, Default isn't an option to load worlds unless you modify the data_sources in the app_,metadata.json in a fresh install), the new world is saved in the default/worlds folder and has to be copied back to the game folder.

I guess this isn't a big problem if you use default for the game folder, but as mentioned, it doesn't appear as a valid source unless it's added to the data_sources.

Requested by @trsh.

I would like a feature where I can increase (maybe also decrease) timeScale, i.e. make everything (including physics) faster.

And a option to write to write custom data (like json) to a file or/and even better an API to subscribe and call remote network sockets.

These 2 things would allow me to bring reinforcement learning (RL) to IOLITE.

Use cases for timeScale:

One example is slow motion in certain situations. Another to fast-forward some gameplay episode. Then putting the game process in hold with TimeScale 0. And list goes on. I was using it all the time while making games in Unity. For machine learning its essential to speed up the learning process simulation.

Use cases for writing files:

Save games, statistics, or something very specific for the game to store persistent data. For machine learning it would be 1 way to push data forth and back from RL learning backend, which is on Python.

Calling external network protocols:

Again lots of use cases. Like fetching Ads info, Saving game data on remote server etc. For machine learning this is second way to transport data forth and back from RL learning backend on Python.

Again why Python backend?

There are no good alternatives. All cool RL ML libs are written on Python. And every integration I know work this way. Unity's ML agents and new UE5 Agents as well.

Why RL:

With RL one can train very realistic NPC behavior. Its still not very popular for big games. Mostly they use behavioral trees. But I can see it becoming more and more actual. Besides The npc thing, you can also train A.I. to build terrains and beyond.

Something similar to unity drives or articulation bodies would do, I think.
Via API of course.

It should have an option keep_transforms, what means, that new transforms will be calculated, so the parented child node stays exactly the same. We could also add keep_transforms to create_with_parent.

I find my self counting 1 by 1 to get the id/number of the color for palette to use in code.
We can think on how to map this more efficiently. But for starters, maybe a small number (color int code) in palette window, for each color, could do?

Scroll up or down to change this factor by some float. This can help to more organically navigate trough the scene. Its like this in UE5 and ppl like it a lot.

Requesting variant.from_uint8() function.
setting uint for uint8 causes application to crash.

This sounds a bit insane maybe :D, but I would like to be able, to put a custom shader on a shape.
Any shader language works for me.
Input could be depth, original calculated color, normal, etc. of the shape.
Output my defined/modified color.

Why?

Useful for planet simulations- For pixel precision heightmap from far away.
Displaying misc distant things, like moon in background, without faking it with a small voxel, then you have to displace, to not run into it.
Textures, when needed.
Own water shader.
Flame shader, etc.

This is potentially caused by the depth of field being rendered in half resolution and missing small pixels in the downsampling process.

When assigning palettes from the editor (pressing the palette button and choosing a different palette to the one the vox file used) the name of the palette appears in the property window and is shown in the world.

However, saving the world doesn't appear to save the palette information.
I tried to save multiple times and checked the contents of the json file but the paletteName properties are empty - they have a "value": "" instead of the "metal" palette I had chosen.
I also tried save world as and checked the contents of that file, no palette values either.

Encountered in pro 0.5.0-beta19

• Fn for removing individual events, not just resetting all or none
• Updating event data (tho this is tricky, if many events have same name)

Play along also with #16

Suggested by @trsh.

Right now there is no slider, and I can input any values, negative ones as well, even min and max is the json

The idea:
Additionally to current params we can add:

• group index
• persistence flag

If persistence flag is set, we don't need to redraw debug shape on every tick. And we can cleanup with a new function clear_group(group_index).

The use case is when calculating the positions and rotations of the debugger shapes is expensive, and we dont want to do that on every tick.

Currently, to achieve this, I am cashing the position and rotation of the debug shapes in a array and reading it on every tick... and I was just wondering, if its possible to make this process more performant on engine side.

Within the UI, there is a simple option to make an element invisible or visible once again by clicking the eye icon on the entity.

Within the Lua API there is no method to accomplish this.

I have an entity with a particle emitter attached to it, I would like it to emit particles only when a specific condition is met within the script. I also have numerous rooms in my game which contain a number of voxel blocks, I would like to be able to activate these blocks as I get within a certain proximity of them.

Currently I am unable to do this.

• in progress
• done

or similar.

Request for a feature that allows mouse cursor to overlap screen boundaries like it has been done in other popular game engines.

When you move your cursor to the left of your screen while changing a value, the cursor teleports on the right side of the screen allowing you to continue changing the value without need of releasing the mouse button.

When I have a lot of vox's, the scroll can get really large and sensitive and its hard to find shapes.

This could come with a small example Plugin (nothing fancy) for better kicstart and clarity.

void (*find_entities_with_component)(const char* name, io_ref_t* entities, io_size_t* entities_length);

Feel free to close, if you think is better to do this on plugin side

VoxelShape.fracture(shape, voxel_coord)

Expose fracturing to the API. Mask regions that should be separated.

Reported by @2latemc.

shape_io->disptach_event(shape_ref, "burning", (void*)event_i_data)

We already have mechanism for getting those, i.e. on_shape_events

Based on the request by @Danchyg1337 to add "dirty flags" to nodes.

After trying to work with bigger projects it has became almost impossible to manage the large amount of assets in the project.
I would love there to be some simple folder system for organizing my project, this would help me a lot.

I like how it looks and works, but keeping track of what is highlighted to remove it later can be cumbersome.

So maybe there could be an additional option, and when enabled, I have no call highlight_node on every tick, otherwise the effect disappears. Similar how io_debug_geometry->draw.. works.

Suggested by @trsh.

When placing entities via the "R" shortcut in the editor, the ray-cast may hit the shape (or shapes) currently placed.

I suspect this relates to placing hierarchies of entities instead of a single entity with a shape attached, which is currently not handled.

Reported by @Danchyg1337.

I tried spawning a prefab at the start of the game, it appears but when I exit game mode it is still in the world and not visible in the world inspector.

The editor currently looks like this on my 3440x1440 display, and the text is a bit too small to work comfortably with it. A scaling/font size option in the settings would be great.

I just installed iolite on windows 10 22h2 and it doesn't launch. I just get the error "The Procedure entry point vkResetQueryPool could not be located in the dynamic link library C:\Users\USERNAME\Downloads\IOLITE\Iolite.exe".

System Specs:
CPU: intel core i5-8300H running at 2.30GHz
RAM: 8GB
GPU: Intel UHD Graphics 630

I have Vulkan working on my device and the latest graphics drivers that Dell recommends. Does anyone know how to fix the error Does anyone know how to fix this?

For stuff like glass (windows for houses is most popular example) and ice- not sure how to name it, partly transparent / distorted transparent.

In Unity has, for example, we have Trigger collision flag. It means, this object wont collide physically, but still give feedback events.
