I just started the tutorial on using the WCK, but when i reached this step, it didnt work properly:
Create a Simple Body Containing Multiple Shapes
Create a new symbol with a base class of wck.BodyShape. Within this symbol place two boxes so that they overlap, but are not completely on top of each other. Try rotating, scaling, or skewing them. What you are creating is a body (the symbol with base wck.BodyShape) that contains two shapes (the two transformed boxes). When done, drag your new body symbol into your world.
Drag another instance of this body symbol into your world and try scaling, skewing, and rotating it so it looks drastically different than your first body instance.
Debug your project. The shapes within each body symbol should move as if they are one body. The transforms (skew, scale and rotation) you applied to your symbols should also correctly translate into the physics simulation.
What happens, is that the movieclip, with baseclass and component definition class wck.BodyShape, containing the two rectangles, just falls straight down through the bottom ...
what am i doing wrong?
