Libgdx和Box2d與CircleSgape一起旋轉紋理

Question

我想製作一個球，到目前爲止，我已經在我的圓上呈現爲簡單紋理，並且紋理沒有旋轉球。以下是我迄今爲止：

bodyDef = new BodyDef(); 
    bodyDef.type = BodyType.DynamicBody; 
    bodyDef.position.set(new Vector2(240,320)); 
    body = world.createBody(bodyDef); 
    CircleShape dynamicCircle = new CircleShape(); 
    dynamicCircle.setRadius(15f); 
    FixtureDef fixtureDef = new FixtureDef(); 
    fixtureDef.shape = dynamicCircle; 
    fixtureDef.density = 1.0f; 
    fixtureDef.friction = 0.5f; 
    fixtureDef.restitution = 0.8f; 
    body.createFixture(fixtureDef); 
    body.applyTorque(100000000); 

而在渲染我：

batch.setProjectionMatrix(camera.combined); 
    batch.begin(); 
    batch.draw(texture, body.getPosition().x,body.getPosition().y); 
    batch.end(); 
    world.step(BOX_STEP, BOX_VELOCITY_ITERATIONS, BOX_POSITION_ITERATIONS); 

任何想法，我怎樣才能使紋理旋轉呢？提前致謝。

Answer 1

batch.draw(texture, body.getPosition().x, body.getPosition().y, width/2, height/2, width, height, /*scaleX*/1, /*scaleY*/1, /*rotation*/ body.getAngle() * MathUtils.radToDegree, srcX, srcY, srcWidth, srcHeight, /*flipX*/false, /*flipY*/false);
