Flash QuickBox2d skinMc.gotoAndPlay（1）;

Question

I have this quickBox2d code to add a cricle to the stage:

var ball:QuickObject = sim.addCircle( {skin:skinMc, x:10, y:10, radius:3, density:0 } );

The skinMc contains animations so I want to be able to refer to it like this: skinMc.gotoAndPlay(5); but it says

Type Coercion failed: cannot convert skinMc$ to flash.display.MovieClip.

ball.gotoAndPlay(5); doesn't work either since it's a QuickObject, not an mc...

Any help will be appreciated

Thanks

Answer 1

ball.userData.gotoAndPlay(5);

userData将是由QuickBox2D填充的DisplayObject。

Answer 2

var sim:QuickBox2D = new QuickBox2D
var ball:QuickObject = sim.addCircle( {skin:skinMc, x:10, y:10, radius:3, density:0 } );

//something along these lines 

So to reference the object you can use:

sim.gotoAndPlay("5");

im not 100% on what your doin but i installed both packages and created a quick document and it works fine on my machine. if need be try this link http://www.emanueleferonato.com/2009/08/25/simplify-your-box2d-projects-with-quickbox2d/
