Hey RenatoB,
thanks for the compliment. I'm afraid though I pretty much abandoned that blog, although there are frequent requests to continue the tutorial. It's a very big maybe.
You could try to apply the events of this Construct Classic example to C2, it's what I did at first as well. But to be honest this version feels convoluted to me in many ways. The C2 version just is a lot slicker.
In any case you might also want to take a look at what rexrainbow did with his own plugins in C2:

Oh and btw, my name isn't Igor :D
That's just from a game I worked on.
