  • If this works everywhere except Cocoon.io then it's most likely a Cocoon bug. Local storage is a standard browser feature so if that's not working it must be caused by the engine. I suggest reporting this to Ludei.

  • Sergeyk I am having the same problem with localstorage save and iOS export from Cocoon. I wish they would answer your bug report in Cocoon's Forums.

    But have you tried recompiling a previously exported version of your game before r231 as you noticed that's when the problem started happening? I'd love to know if a previous version of Construct fixes the problem.

  • I noticed the problem in C2 v-227 and higher. Unfortunately I cannot say anything about previous versions of C2.

  • You used system webview or webview+ ?

  • Both webview and webview+ don't work with local storage at this moment! You need to go only with canvas+

  • Yep. Go with Canvas+. I don't think a fix is coming anytime soon for WebView.

  • Cocoon.io still hasn't fixed this. Can't wait to see what Scirra has up their sleeve for mobile app building so we can forget having to use 3rd party builders.

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

    Try Now Construct 3 users don't see these ads
  • i dont like cocoon, too much problems.

  • what do you use spectrelonewolf ?

  • I use XDK intel, but i read if you can export with cocoon you have better result in

    game performance. I was try and try but and only have black screens and crashes.

    I was exported in croswalk and web view, but i think my problem causes are plugins <img src="{SMILIES_PATH}/icon_e_biggrin.gif" alt=":D" title="Very Happy">.

    In XDK i have good performance for my game in android with Quadcore and 1gb of Ram, i dont know about your game.

    this is my game https://www.moras-alejandro.com/Ahorcad ... index.html if you want see.

    hahaha sorry about my eng.

  • I used to use Intel XDK but randomly it would export a bad version of my game that would lag on some devices. And I also ran into issues with getting some plugins to work. Cocoon we view+ used to work great, but then I switched to canvas for iOS when they were having issues. Coocon puts out a fast performing game, but sometimes the server is down or has other issues. Nothing is perfect, but so far I've had a better experience with Cocoon.
