Dear all,
I’ve searched but nothing comes really handy. I’d like to draw a Bezier curve, or another kind of curved path for what it’s worth.
What is the best way of producing curved paths?
My solution is not efficient.
Right now I am creating a newPolygon with a discretization of the Bezier curve, but it’s ugly if the number of points is low, and probably not worth if I make a 1000 points polygon. I’d like to have the quality of a newCircle, if possible.
Thank you!
Here are some links for you. Some of the links have sample code. One of these should be helpful for you.

I did a quick search (corona draw curved path) and found these links (some overlap with above response).
Not sure if they will help, and some may be a bit old, but maybe they will get you started.

Don’t miss the code links at bottom of article.
Tip: If you click this link and get a blank search page, close the page and click the link again. I’ve found that sometimes when you follow links (for the first time) to the corona code-vault, they re-direct to the search page.
I can’t consistently reproduce this, but sometimes it happens to me.
RoamingGamer,
I did notice same thing. It happens occasionally; then on a subsequent click it does gets to the link. Not a clue as to why.
Thanks
Bob
