    Just to note. I am also running version 138.2

  • I was just going to post about this. r138.2.

  • This is because we added some support for the next version of the CocoonJS launcher, which isn't out yet. It should be fixed at the next launcher update (hopefully in a couple of weeks). In the mean time switch to the old physics engine using the CocoonJS plugin property.

  • Okay ..Thanks :-)

    but where do I find the CocoonJS plugin property

    R/flemming

  • I talked to Ludei about this one.

    I think Construct 2 is using an outdated version of our Box2D extension, an easy solution could be to copy the latest release of out Box2D extension from here: bitbucket.org/ludei/cocoon_cocoonjsextensions/src/1cd24033c801e04591d2017db2d2396189d62d63/CocoonJS_Box2D.js and replace it on the c2runtime.js generated by Construct 2.

    We are working with Ashley to solve this issue.

  • No, r138.2 is now fully up to date with their latest extension. Ludei now need to update the launcher.

  • Would be glad to know how to switch to old engine

  • Would be glad to know how to switch to old engine

    Add the CocoonJS Object.

    Then click it, and edit the properties.

  • very helpful firebelly thank you so much:)

  • Thanks a lot for the info.

    I was crying in front of my pc because my new game version did not work without an apparent reason...

    Thanks again...

  • I had the same problem, I put the cocoonjs plug-in and the option to run standard web-based but now when I open the game in cocoon the screen is black and it says "2 fps" fixed and after 5 seconds the game closes..

    it is frezzed so i cant click in the fps to see the errors..

  • cvp have you checked the new Android launcher (1.4.1)?

  • I have the Latest Cocoonjs Launcher 1.4.1 for IOS, and I have R139. When I change the physics engine to Accelerated I still get a black screen with the exact same error... Any news on this issue?
