IOS Audio Context touch event

[marklundin]

IOS does not seems to recognize a touch drag as a valid interaction to start the audio context. In this example the box has a script which plays audio on mouse click, however if you begin with a touch drag and then click on the box the audio will not play, and no audio can be be played after. The Sound Manager becomes stuck a state where it cannot resume the audio context.

Demo:
This project has a box with a script that plays a sound when you click on it.

1. Touch drag anywhere on the screen
2. Click on the box - > No Audio

What should happen:

1. Touch drag
2. Click the box -> audio plays

FYI, it seems you can workaround this by using the following, however there's potentially some side effects to this...

const updateUnlockingState = _ => {
    if(pc.app.soundManager._unlocked) window.removeEventListener('touchstart', updateUnlockingState )
    pc.app.soundManager._unlocking = false;
};

window.addEventListener('touchstart', updateUnlockingState, true );

Hi @marklundin, this was hopefully fixed in #4789.

Please could you confirm with the next engine release?

Thanks!

I have tested this. @marklundin's project does now work as desired with the latest engine.
