In old version corona sdk I can set xReference and yReference any value like 100, - 100 etc. And I can set this point outside object (it's very important!!!)
Now I try change all my game (ready and publishing on stores) to v2.0 and have big problem with anchorX and anchorY, because its can set from [0, 1] and only inside object.
For little example how do such as the planet's rotation around an external point (like sun). With old API its several lines. How do it using anchorX and anchorY and not using formulas?
I have simular problem with xAnchor and yAnchor when porting game with Marmalade Quick. xAnchor and yAnchor in Maralade doc range [0,1], but when I use - 1, - 100, 100, 2.345 its work fine and solved my problem. In new Corona API if I set like anchorX = - 1.5 then anchorX = 0.
So what I can use instead x(y)Reference ?
