Question

I have a problem with rotating. I know that I can rotate a Texture2D object with the draw method.

我的目标是在180°之前轮换案文。例如,如果我用头部底层的摄像机描绘一个人的情况,我就希望能够轮换,以便头部再次站在上。

此处为守则或轮换:

spriteBatch.Draw(Texture, Position, null, Color.White, MathHelper.Pi, new Vector2(), 1.0f, SpriteEffects.None, 0f);

The rotation works fine, but I have another problem: enter image description here

如果在轮任后,我增加0个职位的案文,则更看不到。

www.un.org/spanish/ecosoc 我如何轮换或可能反映这个目标,以便红点再次出现在最左上角?

public void Draw (
     Texture2D texture,
     Vector2 position,
     Nullable<Rectangle> sourceRectangle,
     Color color,
     float rotation,
     Vector2 origin,
     Vector2 scale,
     SpriteEffects effects,
     float layerDepth)

//Using:
var origin = new Vector2()
{
    X = texture.Width / 2,
    Y = texture.Height/ 2
};


spriteBatch.Draw(texture, Vector2.Zero, null, Color.White, MathHelper.Pi, origin, 1f, SpriteEffects.None, 0f)`
