I'm a complete newbie to Box2D and I am forced to work on an older version of Jbox2d that has EdgeChainDef.
Basically I'm trying to achieve a hollow polygon ( a circle or an arc ). I have computed the points Vo..Vn in the anti-clockwise direction ( Vo is not equal to Vn ). I then try to create an EdgeChainDef with these points using the following code.
Code:
EdgeChainDef pd = new EdgeChainDef();
pd.density = density;
for (Vec2 vertex : vertices) {
pd.addVertex(vertex);
}
pd.setIsLoop(false);
body.createShape(pd)
I then create some dynamic bodies made out of regular polygondefs that fly around the screen. These objects collide with the edgechain from only one side. I want them to collide from both sides of the edge chain. What am I doing wrong here?
Also, if the method I'm using to create a static wall like above is not good, please suggest a better way to create static shapes.
