Button XNA按钮悬停

我的游戏里有一个按钮。我想让它在鼠标悬停在按钮上时切换为其他按钮图像，在鼠标不在按钮上时切换回其他按钮图像

问题是当鼠标离开按钮矩形区域时，它不会变回第一个图像

我的代码如下：

    public override void Update(GameTime gameTime)
    {
        base.Update(gameTime);

        MouseState mouseState;
        mouseDiBack = false;
        mouseState = Mouse.GetState();

        if (new Rectangle(mouseState.X, mouseState.Y, 1, 1).Intersects(backButtonRectangle))
        {
            backButton = backButtonHilite;
        }

        if ((mouseState.LeftButton == ButtonState.Pressed) &&
            (new Rectangle(mouseState.X, mouseState.Y, 1, 1).Intersects(backButtonRectangle)))
        {
            mouseDiBack = true;
        }




    }

    public override void Draw(GameTime gameTime)
    {

        spriteBatch.Draw(ScoreBG, ScoreBGRectangle, Color.White);
        spriteBatch.Draw(backButton, backButtonRectangle, Color.White);


        base.Draw(gameTime);

    }
}
}

你知道我该怎么做吗？

当鼠标移出范围区域时，你没有将backButton设置回原来的状态。看看下面的代码，注意在Update函数中添加的ELSE语句

 defaultBackButton = backButton;   //Save the default back button somewhere outside your update function

public override void Update(GameTime gameTime)
    {
        base.Update(gameTime);

        MouseState mouseState;
        mouseDiBack = false;
        mouseState = Mouse.GetState();

        if (new Rectangle(mouseState.X, mouseState.Y, 1,1).Intersects(backButtonRectangle))
        {
            backButton = backButtonHilite;
        }
        else 
        {
            backButton = defaultBackButton;
        }


        if ((mouseState.LeftButton == ButtonState.Pressed) && (new Rectangle(mouseState.X, mouseState.Y, 1, 1).Intersects(backButtonRectangle)))
        {
            mouseDiBack = true;
        }
    }

正如Jon提到的，当鼠标离开矩形时，您需要将原始纹理设置回原来的纹理

bool mouseOverBackButton = 
    mouseX >= buttonRectangle.Left && mouseX <= buttonRectangle.Right && 
    mouseY >= buttonRectangle.Top && mouseY <= buttonRectangle.Bottom;

backgroundTexture = mouseOverBackButton ? mouseOverTexture: mouseAwayTexture;
mouseDiBack = mouseState.LeftButton == ButtonState.Pressed && mouseOverBackButton;

相当简单的解决方案，您没有将图像设置回鼠标未悬停的情况

       if (new Rectangle(mouseState.X, mouseState.Y, 1, 1).Intersects(backButtonRectangle))
       {
           backButton = backButtonHilite;
       }
       else
       {
          backButton = originalImage; //whatever your Texture2D object may be called
       }

不要指望机器知道你想切换回来！机器是愚蠢的。。好的，这实际上是因为您重写了变量的值，而没有重置它
