动画网格从一个位置到另一个位置

Question

我有一个图像和按钮网格，我想自动从一个位置到另一个位置（实际上是左边几个空格）的动画，但它没有工作。我已经尝试在 xaml 中使用故事板并以编程方式使用下面的代码，但它现在可以工作了。请帮忙！！！

    public static void MoveTo(Grid target)
    {
        Canvas.SetLeft(target, 0);

        var top = Canvas.GetTop(target);
        var left = Canvas.GetLeft(target);
        TranslateTransform trans = new TranslateTransform();
        target.RenderTransform = trans;
        double newX = (double)(left - 300);
        double newY = (double)top;
        DoubleAnimation anim1 = new DoubleAnimation(top, -15, TimeSpan.FromSeconds(10));
        //DoubleAnimation anim1 = new DoubleAnimation(top, newY - top, TimeSpan.FromSeconds(10));

        DoubleAnimation anim2 = new DoubleAnimation(left, newX - left, TimeSpan.FromSeconds(10));
        anim1.AutoReverse = true;
        anim1.RepeatBehavior = RepeatBehavior.Forever;
        trans.BeginAnimation(TranslateTransform.XProperty, anim1);
        trans.BeginAnimation(TranslateTransform.YProperty, anim2);
    }

完全TranslateTransform 不适合你想要的。更好地使用思考动画

我建议你不要使用 Canvas 并将其更改为网格，但如果你使用 Canavas，请使用此代码

 private void Animationsss(Grid grd)
        {
            //create an animation
            DoubleAnimation da = new DoubleAnimation();
            //set from animation to start position 
            //dont forget set canvas.left for grid if u dont u will get error
            da.From = Canvas.GetLeft(grd);
            //set second position of grid
            da.To = -100;
            //set duration
            da.Duration = new Duration(TimeSpan.FromSeconds(2));
            //run animation if u want stop ,start etc use story board
            grd.BeginAnimation(Canvas.LeftProperty, da);

        }

如果您使用网格代码是这样的：

 private void Animation(Grid grd)
        {
            ThicknessAnimation ta = new ThicknessAnimation();
            //your first place
            ta.From = grd.Margin;
            //this move your grid 1000 over from left side
            //you can use -1000 to move to left side
            ta.To = new Thickness(1000, 0, 0, 0);
            //time the animation playes
            ta.Duration = new Duration(TimeSpan.FromSeconds(10));
            //dont need to use story board but if you want pause,stop etc use story board
            grd.BeginAnimation(Grid.MarginProperty, ta);
        }

你可以使用不透明动画来淡化你的网格......如果移动和淡化它会显示出很好的效果！

    private void Animationsss(Grid grd)
        {
            DoubleAnimation da = new DoubleAnimation(1, 0, new Duration(TimeSpan.FromSeconds(2)));
            grd.BeginAnimation(Grid.OpacityProperty, da);
        }

如果没有任何理由，您可以将画布更改为网格，并且还可以更好地使用TranslateTransform来调整大小控件，例如如果鼠标输入，则此代码下面的代码调整大小控件：

private void grid1_MouseEnter(object sender, MouseEventArgs e)
        {
            //at first its normal size
            ScaleTransform st = new ScaleTransform(1, 1);
            //animation size to 1.25 persent of real size
            DoubleAnimation da = new  DoubleAnimation(1,1.25, new Duration(TimeSpan.FromSeconds(2)));
            //set transform to control
            grid1.RenderTransform = st;
            //animation transform now From Y And X
            st.BeginAnimation(ScaleTransform.ScaleXProperty, da);
            st.BeginAnimation(ScaleTransform.ScaleYProperty, da);
        }

如果你的宽度或高度动画做同样的工作，比如缩放变换:)

希望我能帮到你...:))
