Windows Universal Target Not Working

[RuiCuco]

I'm using VS Community 2022. The program stops with a breakpoint in a _debugbreak() call. The log says this before the breakpoint:

DXGI ERROR: IDXGIFactory::CreateSwapChain: No target window specified in DXGI_SWAP_CHAIN_DESC, and no window associated with owning factory. [ MISCELLANEOUS ERROR #6: ]

And then it continues:

A breakpoint instruction (__debugbreak() statement or a similar call) was executed in ek.exe.

Error: The specified module could not be found.

Am I doing something wrong? It works in HTML5 target.

Haven't used the UWP target in forever, totally possible that it just broke. Please open an issue about it.

The reason I'm interested is because I don't really know which target to use to publish in the Windows Store. Can you help?

[RobDangerous]

Nowadays that's actually done with the GDK (Microsoft themselves basically gave up on UWP for games). I have code for that but it's in the Xbox-target which is not public. Have to split it apart.

[RuiCuco]

I see. There are quite a few Windows targets in Kha. I tried the one that said simply 'Windows', but when running from VS Community there was an exception thrown (write access violation) in file constantbuffer.c.h here:

static void setMatrix4(uint8_t *constants, int offset, kinc_matrix4x4_t *value) {
float *floats = (float *)(&constants[offset]);
for (int y = 0; y < 4; ++y) {
for (int x = 0; x < 4; ++x) {
floats[x + y * 4] = kinc_matrix4x4_get(value, x, y); // ****** Here ******
}
}
}

1 - Is this target functional, or did I do something wrong?

3 - Does this target allow publishing in Windows Store?

2 - Can you clean up the VS Code Kha extension, so that only relevant current targets remain?

[RobDangerous]

1. That target is functional. Can't tell what happened without seeing your source.
2. Maybe, not sure. They added the feature to publish regular Windows applications at some point but I don't know the current state of that.
3. I'm not aware of any irrelevant targets being in the extension.

[RuiCuco]

2. Ok, thanks.

3. Well, there is Android (Native) and Windows Universal, which doesn't appear to have much use. And what about WPF, what is that?

[RobDangerous]

3. Windows Universal is still useful for Xbox and WPF is a C#-build using Windows Presentation Foundation. But I did indeed forget to remove Android-Native - will be fixed, thanks.

I see. Sadly, I couild not get khamake to build for WPF (this looks okay for the Windows Store, or am I wrong?). There are some errors:

Haxe compiler error.

No, that's absolutely not suited for the Windows Store. The WPF target is very slow (and that can't be helped because of restrictions in WPF itself) and lacks many features - it's only useful for integrating some Kha-thing into a WPF application.
