hi, im new to all this but thought i'd ask. how to attach sprites to bodies in alchemy port?

can i do something like:

Code:

...
bodyDef.userData= new sprite();
...
body= world.CreateBody(bodyDef);
body.CreateFixture(fixtureDef);
addChild(bodyDef.userData);

this won't link the sprite and body. am i doing something wrong? or do i have to update sprite position by calling a function?

thanks!

You'll have to update the sprite manually. This is the core concept of WCK. A MovieClip is assigned to the userData, then after each timestep it updates the position and rotation of the MC based off the Box2D properties.
