Right now we build Xenko as a single package.
Ideally we should move on to do something more in line with what NuGet expects:

• One NuGet package per dll
• Use "runtimes" for platforms and graphics API
• Games would move from referencing huge Xenko to referencing Xenko.Engine and Xenko.Physics for example.

Other area of improvements:

• Compiling with PackageReference against a local development version (we currently use this "redirect" concept but it's not great). This might need some improvements/discussion with NuGet team.
• Simplify target files
• Review up to date check
• Possibly cross compile multiple platforms from a single solution (TargetFrameworks)

Use cases:

• Create solution from VS & add Xenko from NuGet package manager, then open it with Game Studio
• Use only specific part of Xenko from any Visual Studio project
• Create nuget packages from your code/assets and publish them on nuget so that anybody can use them easily
• People can customize small part of Xenko and only publish the modified part in their own streams.
• Much faster to update (i.e. no need for everybody to redownload sample if we update only a specific part of the engine)

I need Visual Studio? Documentation says that it's optional. I installed .net sdk

A lot of this seems dated and I have concerns about the data collected section now that this is open source. It's misformated on the website, but you guys can check it out below. It talks about "not comparing stored voice recordings?" How would Xenko even know if there were voice recordings or do you guys record our voices? I'm not entirely sure or if there was a translation issue.

Hello, i was wondering if it was planned to allow the editor to be used on other platforms than Windows such as Linux and MacOS in the future like Unreal Engine ? since there are some cross platform and open source UI frameworks in C# that could maybe help the transition
There is avaloniaUI for instance that is a cross platform C# UI framework xaml based under the MIT license too https://github.com/AvaloniaUI/Avalonia

Idea is to allow users to have LOD with a small custom script, while a better system is being designed.
Starting point for such a script: #37 (comment)

It could either be an asset template or a component in the Engine class (first option is maybe better so that it is not hardcoded in engine and user can customize/extend it).

Probably need to adjust how to find current camera, and ideally gamestudio should automatically fill the ModelComponent to the one contained in the Entity this script is added to.

Can't start xenko. Kept having this error

Could not find a compatible version of MSBuild.

Have an animation editor to easily create cut-scene or animate properties.

TODO: Had some specs in the past, need to find them for future reference.

Hi,

I think the DebugTextSystem should be renamed to DebugSystem and a bunch more features be added. Such as:

• DrawLine
• DrawCube
• DrawSphere
• etc.

These methods should take size/position in world coordinates and a color. I am not sure if they should also have a duration and depthTest options like Unity does.

The ScriptComponent.DebugText property should also be renamed to Debug.

Cheers,
dfkeenan

Sorry I am completely new to this engine (and 3D development in general) but after I installed version 3.0.0.1 I received this error:

An error occurred while installing version 3.0.0.1. Value cannot be null. Parameter name: path1 at System.IO.Path.Combine(String path1, String path2) at Xenko.Core.Packages.NugetStore.OnPackageInstalled(Object sender, PackageOperationEventArgs args) at Xenko.Core.Packages.NugetStore.d79.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Xenko.LauncherApp.ViewModels.PackageVersionViewModel.<>cDisplayClass550.<b_0>d.MoveNext()

And then when I launched a project it said it couldn't find Microsoft.Net.Sdk

This is probably something very simple and I'm just lost. (Plus I've worked 63hrs this week so my mind isn't functioning at it's best.)

Hey would it be possible to get OpenVR support for Xenko?

I am going through the API docs and seeing that there is no direct support for OpenVR.

https://github.com/ValveSoftware/openvr

This is on a project upgraded from 2.1 to 3.0. The upgrade looks like it worked as expected, but when I build (from VS 2017) the build seems to remove a project reference as well as a nuget package reference I've added.

In the old system it did sometimes regenerate the .game csproj file, but it seems like it's always regenerating the .csproj file now?

Is there a way to keep the nuget package reference and the project reference when the project is regenerated? I don't see anywhere in the editor where I can do this but I figure I might just be missing something obvious.

csproj diff

When creating a new game/samples or updating platforms, the wizard says the required components are not installed for iOS, Android and UWP, even if the appropriate programs/modules are installed.
This is because the detection code is pretty outdated and needs to be updated.

XenkoConfig.cs contains the code:
https://github.com/xenko3d/xenko/blob/0669deabfe65a04f80041433420f0ace0ad5ca9a/sources/engine/Xenko.Assets/XenkoConfig.cs#L97

Hi,

It would be great if you could subscribe to Events from with in Game Studio, rather than the current method (at least by example) of have (static) EventKeys subscribed to in code.

cheers,

The launcher crashes with the message “An error occurred while updating the launcher” even after a complete uninstall.

Right now there is a private Teamcity instance.
I plan to open it up (read-only) with its config stored on a github so that anybody can create a similar instance.
Also, it would be good to be able to test PR with maybe a simple trigger message in the PR like "Test this PR please".
Note: rationale for doing it on demand rather than automatically is to avoid security risks, since some scripts/code are executed during the build.

I don't think this is a new issue with v3 as I had a problem in v2 that could only be solved with the same solution. I am just getting much more information in v3 to report.

I am moving over a flowing water demo to v3 that I was going to share with the forums but I get the attached asset shader errors.txt when the build is run. The only way to get past it is to kill the process Xenko.Core.Assets.CompilerApp_ExecServer.exe.

In v2 I had an error with no other details, but killing the old equivalent SiliconStudie-named exe was the solution. It does not always happen, but once it does, it will happen every time and even re-starting my PC does not seem to fix it. Then randomly it will stop for a while. Almost seems like it's running two compilers once I do something it does not like>?

The shader being compiled is ScriptedWaterShader.txt (with extension changes to .txt for GitHub, it's .xksl in my project).

Hello,
Would it be possible to get a terrain system in Xenko?

This has been on the road map for a while and It would be great if we had this in the engine. This would be useful for large scale open world games as well. :)

As I was thinking about how to tackle on #12 and #13, I thought things would be much easier if we didn't have this xkpkg references + csproj PackageReference duality now that we moved to the new csproj system.

The idea would be to move away from 1 xkpkg = multiple csproj and instead going to 1 xkpkg = 1 csproj (or 1 xkpkg = 0 csproj in case of assets-only packages), to fit better with the approach taken by the new csproj system and nuget.
Then PackageReference/ProjectReference would take over the role of dependencies.

Likely the .xkpkg would be side-by-side with the .csproj file.

Benefits:

• Solution/csproj would become entry-points, not xkpkg (or Solution which contains a xkpkg custom reference)
• Any kind of C# projects/solutions could be opened, much more freedom to compose project as the user want (fits better when user wants to use only specific part of Xenko, or develop plugins)
• Solution/project states should be more easy to maintain (right now we generate .sln on save from package, which prevent any project from outside the package).
• No superfluous duplication of Dependencies/PackageReference (which could be out of sync), Metadata package information, etc...
• Can rely on NuGet and MSBuild evaluation/targets rather than our own dependency resolution mechanism.
• Later it enables the way for the whole engine and user projects to become almost standard nuget packages. This should help a lot for #12 and #13.

Should be easy and makes xenko engine compatible to other projects using latest SharpDX already.

After upgrading to Xenko v3 my visual studio plugin was not generating .cs files for shaders and threw an error when trying to open Xenko Studio so I attempted to re-install it. When trying to install it from the launcher it briefly shows an animation in the progress bar, then reverts back to the install button.

I opened up fiddler to see what it may be trying to do and notice that the package it's pinging is 404 Not Found.

after upgrading from xenko 2.1 all custom shaders in visual studio 2017 have duplicate key files. at least game studio thinks so, although they are not actually present on disk. is there any order of things i can do to fix that? or how would i upgrade my project that this doesn't happen? i could reset the git repo and start the upgrade process again, but in which order should i open/upgrade/save the project files in game studio and visual studio?

EDIT: i have to add, the project was a VS 2015 solution. the errors occurred with 2017. currently trying to get the 2.1 version of the project running with VS 2017 and then i'll try another upgrade.

these are the errors:

then on build:

Our shader system current implementation is slow, complex and difficult to maintain.

Terminology:

• XKSL: Xenko Shader Language

There was an underway effort to switch to something based on https://github.com/KhronosGroup/glslang and https://github.com/KhronosGroup/SPIRV-Cross :

• We only have to work on the part that interest us (XKSL) rather than the full shader stack (HLSL to GLSL, etc...)
• Maintenance is greatly reduced
• Much more things supported out of the box (CS, GS, new shader models, optimizers, etc...)

The design idea is:

• Customize glslang HLSL frontend to be able to parse XKSL to SPIRV (with some XKSL extensions)
• Rewrite a new XKSL "mixer" that will work at SPIRV level (rather than source AST level, making things much simpler)
• Leverage on SPIRV-Cross to output to any format we want: HLSL, GLSL, Metal, SPIR-V, etc...

So far we have a prototype for HLSL generation but there's still quite some work to do on it, and then need to add support for GLSL and others.

Hi,

Though I have never used Unity I feel that the ScriptableObject is quite valuable. Being able to design a data object and save it with various values so scripts can share instances can really improve design time support in editor.

Veldrid looks like a very promising project and could help with graphics api abstraction:
https://github.com/mellinoe/veldrid

not sure if it supports as much as in here:
https://github.com/xenko3d/xenko/tree/master/sources/engine/Xenko.Graphics

but it might still be of help? and maybe @mellinoe is even able to jump in?

As i understand, SharpDX.Mathematics is the same as: https://github.com/xenko3d/xenko/tree/master/sources/core/Xenko.Core.Mathematics

it might be a good idea to switch to that nuget, as it is maintaned and has probably a few bug fixes. i personally contributed a few over there. the big advantage would be that every other project that is using sharpdx doesn't need to convert vectors all the time. this is particularly bothersome when its basically the same code behind...

I sent a report but can't add my email because Windows freeze the application with a crash message. How I can locate the report for paste here?

Hello, i'm sending this because i've an issue with Xenko, my pc is set to install everything on the D drive so visual studio etc all installed on the D drive, and i noticed that it probably caused an issue in xenko since i can't build from the xenko editor, i get an error related to the .NET 4.6.1 framework not found (while it works perfectly in visual studio)
that's the error i get,

[D:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets(1179,5)]: Error: Les assemblys de référence pour le Framework ".NETFramework,Version=v4.6.1" sont introuvables. Pour résoudre ce problème, installez le SDK ou le Targeting Pack pour cette version de Framework, ou reciblez votre application vers une version du Framework pour laquelle le SDK ou le Targeting Pack est installé. Les assemblys seront résolus à partir du Global Assembly Cache (GAC) et seront utilisés à la place des assemblys de référence. C'est pourquoi votre assembly peut ne pas cibler correctement le Framework souhaité.
it's in french since my pc is french, but i can translate quickly, it means that
"the .net framework v4.6.1 is not found, to resolve the issue , install the SDK or the targetting pack for this framework version or retarget the application to an other version of the framework
and the assemblies will be resolved with the GAC and would be used as reference assemblies"

Hello, i'm writing this because i encountered this issue while trying to submit a crash report with xenko

I think it's caused by the fact that Xenko is no longer supported by Silicon Studio so Silicon Studio's crash report server can't be reached anymore

In the current case, xenko crashed while trying to load a model from a .blend file but i don't have the log anymore since after clicking "send" it closed the crash report window so i wasn't able to retrieve the log

Using the new launcher to update the binary release gave me an interesting error. According to the launcher, it knows I have VS installed but thinks it's incomplete. I DO have all the VS workloads required to compile the engine, but I'm running the preview and not the standard release, which makes me think the launcher doesn't properly account for preview versions of VS.

Recently switched from NUnit to xUnit, but the transition is not finished yet.

Things to still do:

• Windows embedded self-contained runner .exe (rather than having hundreds of Main )
• iOS, Android and UWP runners (will also need ability to report results to Teamcity and work with gold images cf #15)

The documentation still links to the old namespaces:

We used to have a central server containing gold images to have some graphics unit tests run again.

Now being opensource, this is quite impractical:

• Difficult to setup (not good, we want people to easily run tests by themselves)
• Would need lot of additional work (server was really rudimentary and working with file shares)
• Security issues (if we give access to this server, who are we allowing to update gold?)
• Hardware differences (we can't expect pixel perfect matches)
• Since images are stored externally, it has to be versioned manually and can easily conflict in case of merges.

The idea is now to commit those images as part of the repository, thus requiring no further setup.
Tests will be allowed to have small differences (due to GPU differences).

This work is partially started but still need further work (allow small differences, make it work on all platforms, etc...)

Used extensively in games, decals will be needed at some point.

Reference: https://discourse.vvvv.org/t/link-topics-2-3d-engine/16544/3

Xenko Game Studio 3.0.0.1 should not require a connected device to Build (F6) the android APK.
Build and Run of course, but there should be an option for generating and signing the APK in the absence of a connected device.

[C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(609,2)]: Error: The "GetJavaPlatformJar" task was not given a value for the required parameter "AndroidSdkDirectory".

Visual Studio 2017 successfully builds and deploys the APK to the device.

( Runs without error but displays blank screen, we suspect the Adreno GPU on this Motorola device is responsible, but this is a separate issue)

In a game project from xenko 2.1 i was referencing some other assemblies and used their namespaces in some files. after the upgrade the project did not have the references to the assemblies anymore and the usage section of the c# files was cleared from the other namespaces. in this case it was SharpDX assemblies.

it was easy to fix by hand, so not that high priority. but annoying anyway.

The default location is C:\Users\User\ .nuget\packages\xenko\3.0.0.1
But would be really appreciable if we can choose where install it, or if install it directly in the same directory of the launcher (like how was before if i remember correctly).
Anyway i'm reall really really glad that Xenko opted for the MIT license, i'm gonna use it every day!!!

if (thumbnailsInProgressAndContinuation.ContainsKey(asset.Id) && System.Diagnostics.Debugger.IsAttached)
{
    // Virgile: This case should not happen, but it happened to me once and could not reproduce.
    // Please let me know if it happens to you.
    // Note: this is likely not critical and should work fine even if it happens.
    System.Diagnostics.Debugger.Break();
}

Virgile: This case should not happen,...

Hi,

I always felt that the Xenko engine was a bit lacking when it came some general helper methods. So I started the XenkoToolkit project but I really feel a bunch of these things should be included in-the-box. For example:

• Find components in entity hierarchies.
• Transforms using the Entity's Transform.
• Transforming things between world and screen space.
• Calculating rays for doing picking using physics ray cast.
• Transforming Prefabs when being instantiated.

I am creating this issue more as discussion. I am not super confident in the quality of my code as they have not been thoroughly tested and my math skills are not great. There are probably also a few questionable design decisions. For example, not sure about all the overloads I did either, may have gone a bit overboard. There are quite a few shortcomings as well, i.e. a bunch of the transform extensions throw exceptions if TransformComponent.UseTRS is false (I couldn't get the math right).

There are a number of things I would do differently if they were included in the engine, i.e. put the Quaterion look at function in the Quaternion struct.

There are somethings I would almost certainly leave out like the material stuff I did. A better option would be to change the ModelComponent and related systems to handle being able to set material properties per ModelComponent.

cheers,

Xenko needs to be reorganized so that Physics, Video, SpriteStudio, etc... should become separate optional packages (referenced explicitely by games).

Also, we would like to be able to more easily create custom asset types and have a proper Game Studio integration (associated importers, editors, thumbnails, previews, etc.)

Doing this work will make Xenko much more extensible in general for people who want to add their own features externally.

It should also make the runtime leaner and better organized (i.e. Video playback currently forces to embed tens of megabytes of native DLL even if the game doesn't use it).

Part of this work is needed for #12

Various ideas this Epic covers:

• Make our task system alloc-free (possible with recent C# version) so that people are not afraid to create thousands of scripts with await
• Reorganize task system so that we can wait various points of engine. So far we only have Update/Draw, but I suspect many scripts wants much more control when they want to run (after physics, etc...).
  Not sure yet if we want some kind of high-level sync point graph editor, or something more programmatic.

Nothing decided yet on that front.
It seems like EmptyKeys have already something, maybe he could quickly describe what he did?

If the main camera of the game has a profiler script attached and it is enabled, a null exception is thrown on startup:

[Game]: Error: Unexpected exception. System.NullReferenceException:
bei Xenko.Profiling.GameProfilingSystem.Draw(GameTime gameTime)
bei Xenko.Games.GameSystemCollection.Draw(GameTime gameTime)
bei Xenko.Games.GameBase.Draw(GameTime gameTime)
bei Xenko.Games.GameBase.DrawFrame()
bei Xenko.Games.GameBase.TickInternal()

if the script is disabled, the exception does not occur.

Currently Xenko uses Small png icons in the editor that are jagged in higher resolutions. Besides of that, for a flat development environment like Xenko Editor, it's better to use flat icons.

I suggest to use Microsoft Visual Studio Image Library 2017, because those images have both Svg and Xaml format that is ready for Xaml UI of Xenko editor, scalable and responsive to the screen. And also, these icons make developer feel like it's homeland as it is Visual Studio icons.

In version 3.0.0.1, after importing a png of a SpriteSheet, I can't open the SpriteSheet editor without manually editing the xksheet file. I tried both double-clicking the sprite, and right-clicking - edit asset.

Is this a bug, or are the docs out of date on how sprites work?
