java - 旋转图集区域 Libgdx

Question

protected TextureAtlas atlas = Assets.manager.get(Constants.ATLAS_PATH, TextureAtlas.class);

AtlasRegion region = interfaceAtlas.findRegion("arrow");

我加载了这样的图像 ( http://marinedealerconference.com/wp-content/uploads/2015/07/right.png ):一个指向右的箭头...

但是我找不到旋转它的方法! 我怎么能够？因为我希望它下降。

Answer 1

虽然可以旋转区域但不能旋转Sprite或 Image

    //sprite:
    public void rotate(float degrees)

    //image - remember to set origin to the center here!
    public void rotateBy(float amountInDegrees)

您可以“告诉”SpriteBatch 旋转区域来绘制它，而不是旋转区域本身:

    batch.draw(region, x, y, originX, originY, width, height, scaleX, scaleY, rotation);
