Full game Construct 2 and Construct 3 to post on Google Play
  • I've recentelly had to build a mobile app that could download games build with Construct 2 and run locally, the solution I've got is handle the game data and sounds in a different way. And here is my solution:

    1- Export your game with the minify option unchecked

    2- Change the way Construct handle sounds, to do that we need to open the index.html and add right after <body> the code:

    	<div style="display:none;">
    	window.playAudioAux = function(url){
    		var output = url.substr(0, url.lastIndexOf('.')) || url;
    		var url1 = output+'.ogg';
    		var url2 = output+'.mp3';
    		var url3 = output+'.m4a';
    		document.getElementById('myAudioogg').src = url1;
    		document.getElementById('myAudiompeg').src = url2;
    		document.getElementById('myAudiomp4').src = url3;
    		document.getElementById('myAudio').src = url3;
    	<audio id="myAudio" controls>
    	  <source id="myAudioogg" src="" type="audio/ogg">
    	  <source id="myAudiompeg" src="" type="audio/mpeg">
    	  <source id="myAudiomp4" src="" type="audio/mp4">
    		Your browser does not support the audio element.
    This will create a new way to run audio. And now we have to change the [b]c2runtime.js[/b] where it calls the sounds, so find:
    [code:2dnaw682]	function C2AudioInstance(buffer_, tag_)
    And add right after that 
    [code:2dnaw682]		playAudioAux(buffer_.src); return;[/code:2dnaw682]
    This will stop the normal call of Construct and call the function that we just added on the index.html
    3- Most(maybe all) browsers see requests from local as a security problem so we have to load that game [b]data.js[/b] in a different way, open it so you can copy its content. Also inside [b]c2runtime.js[/b] find the following code inside requestProjectData function:
    [code:2dnaw682]"GET", datajs_filename, true);
    		var supportsJsonResponse = false;[/code:2dnaw682]
    And then add after that this code:
    [code:2dnaw682]self.loadProject(FULL_CONTENT_INSIDE_YOUR_DATA.JS); return;[/code:2dnaw682]
    This will load your game content and cancel the request to load data.js.
    4- Inside index.html comment the alert about running the game locally like this:
    [code:2dnaw682]//alert("Exported games won't work until you upload them. (When running on the file:/// protocol, browsers block many features from working for security reasons.)");[/code:2dnaw682]
    That is it!  , It runs fine inside firefox, android webview etc. The only one that still doest run it is Chrome for security reasons...
    Hope it helps anyone with this kind of problem.
