@AceNinjaFire I just wanted to delete my post because I told myself that it probably did not respond to your request ...Perhpas, it was a little bit too complex to start. Sorry for that.

@AceNinjaFire said:

it’s not an easy read.

That's sure, at least 😀
I don't know any other doc but we learn by practicing or by finding some examples in this marvelous forum

@AceNinjaFire Or it is better to try @mikael 's WKWebView

@AceNinjaFire try this, then see the script, only as a small sample. Hoping it will help
Run it, wait some seconds and watch the topic scrolling and the avatars images

@stephen I can understand that. Due to my experience of (very) old guy using (very) old tools, I like to do all myself and I never have used Scene. I also prefer do animations my self in update method.
Good luck and have fun...

@stephen ok, understood. I'm really not a specialist of games or scene but I wonder if there are no functions for the physical aspect of the movements.
Hoping other guys will help you. And sorry, I shouldn't have doubted 🙄

@stephen first remark, setting tx,ty,sx,sy is useless, isn't it?

    def touch_moved(self, touch):
        tx, ty=touch.location
        sx, sy=self.subject.position
        self.touch_loc=touch.location 

@stephen I'm sincerely sorry but, perhaps/obviously due to my poor English, I don't understand what you want to do with this script.

Whaaaaaa. Marvelous. I feel so little and humble after that

@JonB Thanks a lot, I'll try to understand it in my afternoon
