Unfocused game window + audio pausing

tvghost · 2018-08-31T05:47:00+0900

Once you click away from the game or minimize it, the audio in-game still plays in the background. Is there a way to either silence the audio or completely pause it until the player clicks back into the game or focuses on that window? There's a few threads floating around about solutions for Ace, so I'm wondering if there's anything similar for MV.

Feel free to try the plugin below. It is supposed to pause the whole game and silence the audio when the game window loses focus. Audio and the rest of the game resume when the window regains focus.

Code:

// PauseOnBlur.js
// Created on 9/27/2018

var objYeth = objYeth || {};

objYeth.pauseAudio = function () {
    objYeth._pausedBgm = AudioManager.saveBgm();
    objYeth._pausedBgs = AudioManager.saveBgs();
    AudioManager.stopAll();
};

objYeth.resumeAudio = function () {
    if (objYeth._pausedBgm) {
        AudioManager.replayBgm(objYeth._pausedBgm);
    }
    if (objYeth._pausedBgs) {
        AudioManager.replayBgs(objYeth._pausedBgs);
    }
};

objYeth.pauseGame = function () {
    objYeth.pauseAudio();
    objYeth._gamePaused = true;
};

objYeth.resumeGame = function () {
    objYeth.resumeAudio();
    objYeth._gamePaused = false;
    SceneManager.update();
};

objYeth._gamePaused = false;
window.onblur = objYeth.pauseGame;
window.onfocus = objYeth.resumeGame;

//----------------------------
// Changes to SceneManager
//----------------------------

objYeth.SceneManager_update = SceneManager.update;
SceneManager.update = function () {
    if (!objYeth._gamePaused) {
        objYeth.SceneManager_update.call(this);
    }
};
