Thanks — I create init.js and fb.js according to your tutorial. Also, a have created capx file with described logics etc. But now I have to export my project to HTML and put the init.js and fb.js on html project's folder? Is it way to check the CAPX without exporting/uploading etc?
Sorry I can't get your question...
First you import the js files to "Files" folder in Construct 3 editor,
then you do the logic stuff, after that you export.
After exporting, all files should remain in the original location...
(Sorry for late response)
