this seems to be tied to using a mouse listener. onMouseMove is not synchronous with the frame rate, so it can fire more than once in between frames....that being said, it still doesnt make sense that the _x seemingly increases if you drag left.
if you use good ole onEnterFrame, everything works fine. On 2/28/07, Paul Hoza <[EMAIL PROTECTED]> wrote:
Thanks for the reply... I tried what you're suggesting and still see the problem. I decided to make a quick example to see if anyone can see a problem in what I'm doing (and a demonstration of said funkiness.) This is out of context, so I think it's working okay as a demo. The code is included in case it sheds any light... the sample is pulled right out of my app, so it's the same controller I'm using (out of context, so there were tweaks to get it working standalone.) http://www.gamedevschool.com/samples/flashcoders/dragproblems/dragproblems.html Code: http://www.gamedevschool.com/samples/flashcoders/dragproblems/dragproblems.zip Thanks for any more insights!
