Please look here the example-file:
I had a quick look.
As I observe, this is the case.
The 2 plugins when together, the JS Plugin doesn't work. But, whether the Layout Transition is with the JS Plugin or not, the Layout Transition still works.
The problem with the project seems to be with the JS Plugin expression Function Return Value, because when the error popups, the only method that doesn't work is the return value, but the layout transition still continued.
I think you need to report this to valerypopoff's thread instead.
- The JS plugin is the only one accessing from Construct 3.
- The Layout Transition didn't have any problems running.
- The error came from the JS plugin.
I think this is his jurisdiction. You'll likely find the solution in the JS plugin instead.
It'll be fixed faster in his thread.
Maybe it has something to do with the Layout Transition's files getting in conflict with the way the JS plugin loads.
Anyway, I only ported the plugin into Construct 2.3 Runtime and Construct 3 Runtime. I don't think I did change how the plugin works originally.
It is most likely the solution lies on the JS Plugin, I am confident valerypopoff can fix it for you. Though if ever there is a problem with the Layout Transition plugin I'll be glad to help in what i can.
Have a nice day.
