Anybody knows how to add 2 circle fixture to one b2body with desired positioning?
I know how to add two polygon fixture to one body by using
m_centroid. But how can I do it for circle fixtures.
Any answer will be appreciated. I want to stick some object together. I tried joints but they all are elastic. I want distance static.
You should create two fixtures for your body and the shapes of those fixtures should be
//Create a body. You'll need a b2BodyDef, but I've assumed you know how to use these since you say you've created bodies successfully before. b2Body* body = world->CreateBody(&bodyDef); //Create the first circle shape. It's offset from the center of the body by -2, 0. b2CircleShape circleShape1; circleShape1.m_radius = 0.5f; circleShape1.m_p.Set(-2.0f, 0.0f); b2FixtureDef circle1FixtureDef; circle1FixtureDef.shape = &circleShape1; circle1FixtureDef.density = 1.0f; //Create the second circle shape. It's offset from the center of the body by 2, 0. b2CircleShape circleShape2; circleShape2.m_radius = 0.5f; circleShape2.m_p.Set(2.0f, 0.0f); b2FixtureDef circle2FixtureDef; circle2FixtureDef.shape = &circleShape2; circle2FixtureDef.density = 1.0f; //Attach both of these fixtures to the body. body->CreateFixture(&circle1FixtureDef); body->CreateFixture(&circle2FixtureDef);
