Re: [Flashcoders] { AS3 } Reading position info X, Y, H W
Do you know the rotation? 2 ways to do this: Either rotate the image back to 0 if it can be done - if you do this you will need to call validateNow() on the instance after changing values, read the new w2, etc. then rotate it back... Or do some pythagoras w2 is the hypotenuse of one triangle. h2 is the hyp of another... You can work the rest out :) Glen [EMAIL PROTECTED] wrote: Hi i need some help reading position info X, Y, H W of a desired object.

RE: [Flashcoders] { AS3 } Reading position info X, Y, H W
Surely - by Pythagoras
w2 = square root of (width - x)^2 + (x2 - x)^2
Also might help to know the _rotation angle of the containing element

Re: [Flashcoders] { AS3 } Reading position info X, Y, H W
Yeah i know what the rotastion is, but am not sure what to do with regards to
pythagoras and working out the hypotenuse.
Can you point me to any examples of how to use validateNow() as ive looked
through Flash Help/Livedocs and cant seam to figure out how its used!

Re: [Flashcoders] { AS3 } Reading position info X, Y, H W
Hi,
Sorry I see you are using Flash not Flex, I gotta stop doing that.
If you are using Flash, just changing the rotation should work
straight away - you will see it on screen - don't worry about validateNow()
(If you are using Flex and change properties of a UIComponent, you
may need to call validateNow on that component before it updates the
display, hence other properties.)
To be honest, Pythagoras is easier and more robust than this and if
you are programming graphics, it should be in your arsenal - see the
other guys' reply for a solution, but have a go at working it out first
if you can.
