翻转字符

Question

我想在角色向左\右走时翻转角色，我从不同的身体部位创建了一个角色，因此翻转每个部位都会导致以下情况：

原因当然是因为它将身体部位翻转到各自的位置，而不是所有玩家一起翻转。

之后我有了一个想法，就是绘制玩家来渲染目标并在绘制时翻转渲染目标，它起作用了（有点），但是当我翻转时它向后走并且它也翻转了玩家位置屏幕。这是代码：

  if(mLeavusSprite.isflipped==0)
        spriteBatch.Draw(character, rec,rec, Color.White,0,Vector2.Zero,SpriteEffects.None,0);
        else
            spriteBatch.Draw(character, rec, rec, Color.White, 0, Vector2.Zero, SpriteEffects.FlipHorizontally, 0);

character=渲染玩家被吸引到的目标。

有什么我可以做的吗？手动翻转会很痛苦，我需要手动移动 10 多个动画，每次 4+ 帧两次！

编辑： 这是绘图的代码：

           if (Frame == 0)
            {
                HeadPosition.X = Position.X;
                HeadPosition.Y = Position.Y;
                BodyPosition.X = HeadPosition.X + 8;
                BodyPosition.Y = HeadPosition.Y + 32;
                TopHandPosition.X = HeadPosition.X + 2;
                TopHandPosition.Y = HeadPosition.Y + 36;
                BackHandPosition.X = HeadPosition.X + 20;
                BackHandPosition.Y = HeadPosition.Y + 36;
                HeadSource = new Rectangle(0, 0, this.Head.Width, this.Head.Height);
                BodySource = new Rectangle(0, 0, 24, 54);
                TopHandSource = new Rectangle(0, 0, 10, 27);
                BackHandSource = new Rectangle(0, 0, 15, 27);
                theSpriteBatch.Draw(BackHand, BackHandPosition, BackHandSource,
   Color.White, 0.0f, Vector2.Zero, Scale, FlipIs, 0);
                theSpriteBatch.Draw(Body, BodyPosition, BodySource,
             Color.White, 0.0f, Vector2.Zero, Scale, FlipIs, 0);
                theSpriteBatch.Draw(Head, HeadPosition, HeadSource,
                Color.White, 0.0f, Vector2.Zero, Scale, FlipIs, 0);
                theSpriteBatch.Draw(TopHand, TopHandPosition, TopHandSource,
         Color.White, 0.0f, Vector2.Zero, Scale, FlipIs, 0); 

            }

嗯..这是一个棘手的问题。

可能有几种不同的方法可以做到这一点，我认为将他们的玩家绘制到渲染目标是一种合理的方法，如果你能让它工作的话。

但是，如果您想要一种快速而肮脏的方法，您可以像这样简单地翻转每个部分的偏移量：

var flipOffset = FlipIs == SpriteEffects.FlipHorizontally ? -1 : 1;

if (Frame == 0)
{
    HeadPosition.X = Position.X;
    HeadPosition.Y = Position.Y;
    BodyPosition.X = HeadPosition.X + 8 * flipOffset;
    BodyPosition.Y = HeadPosition.Y + 32 * flipOffset;
    TopHandPosition.X = HeadPosition.X + 2 * flipOffset;
    TopHandPosition.Y = HeadPosition.Y + 36 * flipOffset;
    BackHandPosition.X = HeadPosition.X + 20 * flipOffset;
    BackHandPosition.Y = HeadPosition.Y + 36 * flipOffset;
    HeadSource = new Rectangle(0, 0, this.Head.Width, this.Head.Height);
    BodySource = new Rectangle(0, 0, 24, 54);
    TopHandSource = new Rectangle(0, 0, 10, 27);
    BackHandSource = new Rectangle(0, 0, 15, 27);
    theSpriteBatch.Draw(BackHand, BackHandPosition, BackHandSource, Color.White, 0.0f, Vector2.Zero, Scale, FlipIs, 0);
    theSpriteBatch.Draw(Body, BodyPosition, BodySource, Color.White, 0.0f, Vector2.Zero, Scale, FlipIs, 0);
    theSpriteBatch.Draw(Head, HeadPosition, HeadSource, Color.White, 0.0f, Vector2.Zero, Scale, FlipIs, 0);
    theSpriteBatch.Draw(TopHand, TopHandPosition, TopHandSource,Color.White, 0.0f, Vector2.Zero, Scale, FlipIs, 0); 
}

这是假设Position 位于精灵的中心，如果不是，您可能需要进行一些调整。

听着，我会对你说实话。有更好的方法来解决这个问题，但它们需要对代码进行重大的重新设计，而且很难用一个答案来解释。

我要重构设计的第一件事是创建一个类来表示单个 Sprite 部件，以在一个地方保存公共数据点（偏移量、源矩形、纹理、颜色等）和设置数据。动画代码需要与绘图代码等解耦。
