Hi,
Is it possible to reassign coordinates of a line later ?
myLine=display.newLine(10,10,20,20)
…
Something like:
myLine.x1=20
myLine.y1=20
myLine.x2=40
myLine.y2=40
Thank you.
YourLineObject:append() ?
Look for it in the docs page. I think it’s what you are after 
Edit: i misread your post, if you are looking to do what Ed asks below, then my advice is not correct.
@Shadrak,
Are you saying, you want to change the vertices of the line after you make it?
If so, then I’m pretty sure the answer is, “No.” I generally solve this by removing the existing line and re-drawing it.

Thank you for your answer, the solution also seems to me by removing the existing line and re-drawing it.
I haven’t tried it , but couldn’t you do it with scaling ?
So if you had a line that with scale 1,1 and anchor 0,0 went from 0,0 to 1,1 and scaled it by x,y wouldn’t the end point end up at x,y ? then you could move it to move the origin ?
Some HTML stuff draws lines like this - works with a stock line graphic and stretches it and flips it till it is in the right place.
Really depends on efficiency. It obviously introduces a scale into every line rendering but would stop garbage collection deletion problems maybe ?
It’s probably just as efficient to remove/recreate than it is to change the points anyway.

Might depend on what you were doing with them :)
