[Flashcoders] Re: adding physics to pivot object around a point
So I guess what i'm trying to get at is that I'd like to apply gravity and momentum to an objects angle rather than directly to their y axis anyone have any ideas? thanks a -- hi guys could anyone point me in the right direction to do the following, please? I'd like an object that is dragged to correctly respond to being pulled around by pivoting around the point it is dragged by (also applying downward force to represent gravity) for example, if i hold a pencil lightly at one end, it will pivot around the point i am holding and swing until it comes to a rest pointing straight down. does anyone know of any tutorials that go into this kind of thing? thanks for your help a ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Re: adding physics to pivot object around a point
Well, I know you could do something like this very easily using a physics engine like Box2D (http://box2dflash.sourceforge.net/), but the very easily part only kicks in after you spend several hours converting your entire application to using a third party physics engine. If you're just trying to do some more basic faux-gravity rotation, there's probably simpler ways of doing it. If I were gonna fake it and I had a simple shape like a rectangle to work with, I might esimate what portion of the sprite was to the left and the right of my cursor, use that to apply a little force to some internal _angularVelocity variable, and then combine that with the MatrixTransfrmer.rotateAroundInternalPoint method to rotate my object around the mouse cursor. But I can't promise you that'll necessarily look any good, though. That's just a guess. --T On Mon, Dec 1, 2008 at 10:12 AM, allandt bik-elliott (thefieldcomic.com) [EMAIL PROTECTED] wrote: So I guess what i'm trying to get at is that I'd like to apply gravity and momentum to an objects angle rather than directly to their y axis anyone have any ideas? thanks a -- hi guys could anyone point me in the right direction to do the following, please?

it's also very extensive for what i want to do - mine is for a banner to look nice a On Mon, Dec 1, 2008 at 6:25 PM, Todd Kerpelman [EMAIL PROTECTED] wrote: Well, I know you could do something like this very easily using a physics engine like Box2D (http://box2dflash.sourceforge.net/), but the very easily part only kicks in after you spend several hours converting your entire application to using a third party physics engine.
