I have 3 square. smallest square s3 is inside s2. s2 is in side s1. each is 10px larger
var s1:Sprite = new Sprite(); var s2:Sprite = new Sprite(); var s3:Sprite = new Sprite(); s2.addChild(s3); s1.addChild(s2);
how can I find the coordinate of child in its parent's coordinate system?
trace(x) //10 trace(parent.childXof(s3)) //20 how do I get this?
What you are looking for is the localToGlobal and globalToLocal methods of DisplayObjects
Links to documentation:
They allow you to transform a point from one coordinate space to the other, which is what you are looking to do.
Hope it helps!
