It's a new stable release of Construct 3! If you're updating from the last stable release r148, then this update includes changes from r149, r150, r151, r152, r153, r154, r155, r156 and r156.2.

Highlights include:

JavaScript coding is now supported! Learn to code with one of the world's most popular programming languages. See the blog post Introducing JavaScript coding in Construct for more information, and stay tuned on our official blog for more news.

• You can now add comments in actions!

• Timelines now support tagged keyframes allowing you to synchronise events - or even JavaScript - with timelines.

• There's a new custom ease curve editor to use custom animation curves in timelines and the Tween behavior.

• A new feature called asynchronous actions makes it easier to use actions that run in the background, using a new system action Wait for previous actions to complete. See the dedicated video on async actions for more.

• The Dutch language is now available by default for the editor!

• Much more, including editor optimisations, runtime performance improvements, internal upgrades, and as usual plenty of bug fixes. See the intervening release notes for everything else.

We'll be starting a new beta release update cycle soon. If you'd like to help test it, try the beta release opt-in: choose Notify me about updates for beta releases in Settings. Stay tuned for more updates!

  • Excuse me my dear developers!

    What happened to Construct 3?

    After updating the game, there were problems and failures. The project is compiled under c2Runtime.

    Domestic purchases do not work!

    Please pay attention, you have a problem, developers.

    Statistics on the Google Play developer console.

    Crashes and ANR


    +1 358.82% compared with the previous period.

    • I have the same problem with this version r157, my statistics on Google Play developer console showed many Crashes and ANR.

      I think I'll have to go back to the previous version.

    • Domestic purchases have not worked before! Also now they do not work, only some phones can make purchases.

      I told you to remember?

      I told you that you also do not close the upper curtain, but you did not listen to me! Only in the latest versions finally fixed the hiding of the upper curtain.

      You wrote to me that I was wrong, I was right, please correct, because of these problems, the applications are down, the players are upset.

        I'm afraid we can't help based on comments like this - please file a bug report following all the guidelines, since we need all that information to be able to help. If you have issues with a new release remember you can roll back to an earlier version at any time.

    • I have this problem too

      Statistics on the Google Play developer console.

      Crashes and ANR

      • Thank you for joining this issue, I think the developers are already working on this problem.

        It is necessary for all of us to understand that errors reduce the rating of an application, this is a new system of algorithms that make the quality of your application important, now the algorithms are enhanced so that there are high-quality applications on the market.

        Crashes and errors increased very much after the applications received the latest updates.

        As a result, it was noted that the number of installations per day fell by 10-20%.

  • Thank you!

  • Oh wow! The javascript support is an incredible addition! You've just convinced me to buy a license.

  • Hello! I have a request: please add a splitscreen plugin or something of that sort! It would be very helpful :)

  • Thanks keep it up! :)

  • You showed the timeline curves and I gasped. Then I gasped again at the action commenting. Thank you so much! Big improvements for me.

  • You guys are amazing, power to you!

  • Better do protection against cheaters in your program. Or add a plugin that will prevent cracking of the game, players crack very easily games and programs made on construct ...

  • What is wrong with the construct 3 team. It´s almost not possible to build the xcode version. It´s take more than 1 hour.

  • oi aconteceu um erro no plugin fuction
