Ebiten: Immediate crash when running gamepad example locally

[semilin]

I'm running Void Linux. I copied the code for the gamepad example and removed the // +build example jsgo. It compiles, but upon running it immediately crashes.

[hajimehoshi]

Hi,

Are you using a PS4 controller?

[hajimehoshi]

Unfortunately this seems an issue in GLFW, not Ebiten.

[semilin]

Yeah I am using a PS4 controller. Thanks for the info, I'll make the issue there.

[hajimehoshi]

Thanks! It'd be the best if you could reproduce the issue with GLFW without Ebiten, since the GLFW team doesn't know anything about Ebiten.

[semilin]

Sounds good.

[hajimehoshi]

This might be already fixed after https://github.com/hajimehoshi/ebiten/commit/d08f57e6106eabf50a09f4f91bfca1b566d9dea1, but I am not sure.

[semilin]

At least for me, the error still occurs. In addition, I noticed that my trackpad will be recognized as a controller, which is pretty weird and might be attached to the error.

[hajimehoshi]

Acknowledged. I still think this is an issue in GLFW, unfortunately.

[hajimehoshi]

To solve this issue completely, I'd need to remove the dependency on GLFW, maybe :-/

[SolarLune]

Hmm, I'm running into this problem as well when attempting to run my own project with my controller (8BitDo's SN30 Pro+). Oddly, the mapping (050000005e040000e002000003090000) does seem to exist in the mappings.h file, so it should be found in the controller database...?

[hajimehoshi]

What kind of error messages did you see?

[SolarLune]

Pretty similar to @semilin's:

Well, GLFW's gamepad detection is not good in terms of these issues. I'm thinking to start to fork the GLFW's joypad part to mitigate this issue.

@semilin @SolarLune @corfe83 Now the Ebiten on master has GLFW 3.3.3. Does the latest Ebiten still cause the issue?

[SolarLune]

Hello, sorry for the late reply! Yes, I'm still seeing a crash when launching a game or during play if a controller GLFW doesn't support is connected, and this is after building with ebiten from master (v2.1.0-alpha, according to go).

Fortunately, for my controller (8BitDo SN30 Pro+) I found that there's another mode of connection that allows me to use it with Ebiten while not causing crashes.

I feel like it might be good for me to investigate a bit more to see if it's really crashing because of the controller not being found, or if something else is the issue. It might be simpler to add any missing controller profiles manually (assuming that is the cause) than invest time into a custom gamepad solution that works on all platforms.

FYI this error means that your gamepad has fewer buttons than the gamecontrollerdb.txt entry references for this gamepad. WEIRD.

[hajimehoshi]

Ironically, though the crash was due to SDL's database, SDL's gamepad detection instead of GLFW's doesn't cause this crash.

@SolarLune is that correct?

[hajimehoshi]

If that's true, migrating to SDL (#172) would make more sense.

[SolarLune]

@hajimehoshi Yes, I believe you are correct. I haven't seen this issue arise with the go-sdl2 port of SDL, which might indicate that the issue wouldn't arise on desktop, as an example, if SDL2 was used as a backend for Ebiten.

[hajimehoshi]

Thanks!

There are some options to fix this issue so far:

1. Migrate to SDL (#172): This is not an obvious task of course. Now I'm stuck with porting for Linux. The existing port like https://github.com/veandco/go-sdl2 uses precompiled libraries (*.a), but I don't think this is the way to go for portability.
2. Modify GLFW in go-gl/glfw: This would require forking the repository. There are various ways to suppress this error. For example, if we eliminated all the mappings, the error didn't happen. The problem is that the gamepad name would no longer be obtained.
3. Create our own gamepad library (#1489): This is challenging, but I hope this would not be so difficult. I'd be happy as we could have more things under control :-) The easiest way is fork a part of GLFW or SDL.
