What if they are all gone?
You learn to code yourself? and do your own plugins, as you need them per your projects? Construct was and it seems it still is a javascript/xml based Engine/Code Interpreter and has a fully documented SDK, is not that hard to learn to do plugins, problem is because of R0J0 and others (you could count them on fingers ) the rest of community, over 10,000 -100,000 people, got lazy. If they are gone, i think would be to a rather advancement in their own life and i hope they will do good and be prosperous, they deserve it probably worked their butts off for it. As for us the "can someone help me with a example" we should learn to code our own plugins, especially after some years of being around the Scirra Forum.
If you don't know where to start to learn javascript, there is this free organization that offers tutorials and full courses on javascript and html and i think even sql etc if you follow those courses you can have the skills you need. (this is not an advertising just a free suggestion website)
