Cocoon official support in Construct 2 was dropped years ago, so I'm not even sure Construct 3 was ever supposed to support it at all to begin with.
Yes, but the way OP posts it sounds like he thinks Cocoon is completely unusable. Cocoon is usable with C2 projects, despite the fact Scirra doesnt officially support it (although beware there is a major game-breaking bug with Cocoon at the moment where LocalStorage data doesnt save when you build for iOS using WebView+).
But I'm not sure if you can use Cocoon to build a project exported from C3, I haven't tried. So OP could try Cocoon if he is completely stuck for options...?
Scirra's build service is supposed to be the answer to the retirement of Intel XDK.
Here's hoping. I hope we can hear some more details about what's planned for the build service soon? I have projects developed in C2 that I want to keep updating into the future, and I'm thinking it would be better to keep updating them in C2, rather than migrate the projects to C3, so I am super interested to hear what the details are for supporting building C2 projects in the C3 build service?
Like, will C2 receive updated / working iAP, Game Center and GooglePlay plugins that will work with the C3 build service?
Is there a rough ETA for when the build service would be available for C2? Or failing that, is there a rough ETA for when we might get some details?
I'd like to know, because if the C3 build service is 12 months away or something Id probably be better off going and learning to use Phonegap in the mean time. Ashley seems to be keeping details v close to the chest?
