Does anyone know how to use a gamepad+javascript with Android?

LOL · December 14, 2023, 8:34pm

I tried to use a gamepad with the Anki desktop APP, and it works!

When I enter “navigator.getGamepads()” in the console, it can detect the gamepad I used.

However, it does not work on my Android device. BTW, the browser on my Android device can detect the gamepad (it works fine when opening a gamepad tester website).

Does anyone have an idea on how to solve this problem?

Thank you very much!

Out of interest, are the options in ‘settings → controls’ insufficient, and if so, what could be done better?

Dear David:

Thank you for the effort.

The scenario I was about to use is I want to have the ability to trigger a specific function that is not provided in the default action list. For Example, one button to play the first audio, another button to stop the playing, etc. In other words, the ability to write a customized mapping to any javascript function would give users the freedom to play with their cards.

Thanks you again for the help!

Best
Ye

Hi Ye,

This functionality will be available natively after the following feature request is completed. Should be done this month for the 2.17 alpha series.

Feature Request: Implement 'User Action' Functionality Similar to AnkiMobile

Accepted Anki Ecosystem Compatibility Keep Open Reviewer

In AnkiMobile (starting from version 2.0.88+), there is a feature that allows us…ers to trigger JavaScript in the review screen. This advanced functionality is especially beneficial for those using shared decks that provide keyboard shortcuts to perform actions, such as revealing a hint or the next cloze deletion. By defining a user action, it's possible to trigger these actions with external devices, like a gamepad, or even by using gestures on the screen. For instance, in AnkiMobile, if a card template provides a revealNext() function, users can instruct AnkiMobile to call it with the following code: ``` var userJs1 = revealNext; ``` This feature is especially handy for those who have written their own actions or are using certain shared decks/templates that provide these actions. For more details, please refer to the [AnkiMobile documentation](https://docs.ankimobile.net/study-tools.html). Once on the page, scroll down to the "User Action 1-8" section for specifics.

If you subscribe to the following bug report on GitHub, I’ll have this fixed tonight, and it should be available in AnkiDroid 2.17alpha11: [Bug] `navigator.getGamepads()` returns `[null, null, null, null]` · Issue #14975 · ankidroid/Anki-Android · GitHub

Our alphas are available here: Releases · ankidroid/Anki-Android · GitHub. When testing, I’d recommend the Parallel.A apk, as this can be used alongside 2.16.5

Dear David:
I tried the alpha11 and alpha14 versions today. However, navigator.getGamepads() still produces [null, null, null, null]. What might be the reason? I’m looking forward to hearing back from you.

Thank you!

You need to press a button on the gamepad in order for it to be visible in Javascript
