Touch controls on flatpak

[TheKrafter]

Is your feature request related to a problem? Please describe. Currently, this is the best way to play minecraft on linux phones-- except for one thing-- controls. Input with squeekboard doesnt work great (understandable) but you cannot access the pause menu, inventory, move around, or even look around well without plugging in a keyboard and mouse.

Describe the solution you'd like It'd be great to have an option in the launcher settings to launch the game with touch controls enabled (as there is no option for this in the game itself)

Describe alternatives you've considered Ive tried using squeekboard (the phosh OSK) but alas-- it didnt work.

Additional context This is the only easy and efficient way to play mc on mobile linux.

Touch input is not supported in the flatpak (glfw).

You need to install the AppImage, https://github.com/minecraft-linux/pkg or build from source.

[TheKrafter]

oh ok thanks!

@ChristopherHX might i ask what would be required (or if its even possible) enable touch input on the flatpak?

[ChristopherHX]

what would be required

One of the these options must be true

• Touch support in https://github.com/glfw/glfw and using the non existent touch api
• make it possible to compile eglut and without gampad support (udev not available flatpak), but some users depend on gamepad input
• flatpak would provide udev and switch window management to eglut
• make linuxgamepad not make use of udev and use eglut

Switching to eglut would kill my plans for enabling wayland + x11 again, once glfw 3.4 stabilizes

raylib has touch compatabillity, and also uses glfw, maybe look at what it does

[TheKrafter]

also, the AppImage does not work on non-gnu systems, such as postmarketOS (Alpine-Based). so the appimage isnt even an option for me atm. though i think it could be added to the ci?

[ChristopherHX]

This launcher is not working with alpine libc, my experimental musl port seem to not even run at all / crash very early. The only non gnu libc, which works is the macOS libc.

alpine seem to have gnu libc compat, which may make the appimage / built from source work.

I could add the eglut mode to the flatpak as opt in, this requires the launcher to have two runtime window implementations. One with touch and another one with gamepads.

However this feature may take while as long there is no much demand from the community.

[ChristopherHX]

See this PR https://github.com/flathub/io.mrarm.mcpelauncher/pull/107

This is an eglut build of the flatpak and should have the exact same features as the AppImage, but doesn't require glibc installed directly in the host system due to it's own copy of it.

You can install the test build, if you also have the normal flatpak you might need to type flatpak run io.mrarm.mcpelauncher//test to start it.

[TheKrafter]

Thanks, That build works flawlessly on my PPP with touch controls!

Having eglut as an opt-in mode to the flatpak would probably be the best option, yes. I understand if there isn't demand for this, no worries!

Is this available as an opt-in as of yet?

[Henry-Hiles]

Maybe this can be used? https://github.com/glfw/glfw/issues/42#issuecomment-2346606489

[ChristopherHX]

Is this available as an opt-in as of yet?

No, the interest gone into the void. Having multiple window systems in a single binary hasn't been investigated further.

I rebased the sdl3 port for you, feel free to install it once the flathub bot finishs creating it for you: https://github.com/flathub/io.mrarm.mcpelauncher/pull/137/

Comment there how well this works, may replace glfw sometime in the future eventually breaking change 2.0.0

I'm scared about regressions at this level.

[ChristopherHX]

Maybe this can be used? glfw/glfw#42 (comment)

No, not worth the effort. Killing both eglut and glfw is on my agenda

Thank you, I'll try it tonight!

Works almost perfectly! Only issue is that the imgui ui can't be interacted with, so I can't fullscreen or anything. If that can be fixed this would be perfect!

[ChristopherHX]

Only issue is that the imgui ui can't be interacted with

Just not implemented.

For a quick workaround, is there a way for me to enable alt to focus imgui via a settings file or something?

[ChristopherHX]

write menubarFocusKey=alt into the settingsfile shown in the log

I would just do this with the menubar using a pc mouse on my phone. No my phone has android and the mouse works even there.

Also f11 on keyboard = fullscreen, that should be sticky as well and reapply on rerun.

My nintendo switch ubuntu had a gamepad to mouse emulation.

alt for menu focus this has been removed due to bug reports, some players use alt for gameplay. While there is still an issue with alt and gameplay.

Thank you, I dont currently have the hardware to plug a physical keyboard or mouse into my phone so I'll try this.

Sorry, I can't see the log. Is there no fixed location for the config?

[Henry-Hiles]

Well I'm able to see some of the log
