将网格从一个位置动画化到另一个位置

本文关键字：位置 动画 另一个 一个 网格 | 更新日期: 2023-09-27 18:33:11

我有一个图像和按钮的网格，我想自动将从一个位置到另一个位置（实际上是左侧的几个空格）的运动动画，但它没有奏效。我尝试在 xaml 中使用故事板并以编程方式，如下面的代码所示，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);
    }

将网格从一个位置动画化到另一个位置

完全 TranslateTransform 不适合您希望更好地使用思考动画

我建议您不要使用Canavas

并将其更改为网格，但是如果您使用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);
        }

如果你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);
        }

您可以使用不透明度动画来淡化网格...如果移动和褪色，它会显示很好！

    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 canavas 更改为网格，也可以更好地使用 TranslateTransform 来调整大小控件，例如如果鼠标输入此代码调整大小控件下面的代码：

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);
        }

如果您为宽度或高度制作动画，请执行相同的工作，例如缩放变换:)

您也可以为此使用 xaml：

<Window.Resources>
    <Storyboard x:Key="MoveGrid">
        <ThicknessAnimationUsingKeyFrames Storyboard.TargetProperty="(FrameworkElement.Margin)" Storyboard.TargetName="grid">
            <EasingThicknessKeyFrame KeyTime="0:0:1" Value="-300,0,0,0"/>
        </ThicknessAnimationUsingKeyFrames>
    </Storyboard>
</Window.Resources>
<Window.Triggers>
    <EventTrigger RoutedEvent="ButtonBase.Click" SourceName="button">
        <BeginStoryboard x:Name="MoveGrid_BeginStoryboard" Storyboard="{StaticResource MoveGrid}"/>
    </EventTrigger>
</Window.Triggers>
<Canvas>
    <Grid x:Name="grid" Height="300" Width="300" Background="Black">
        <Button x:Name="button" Content="Move the gird!" Height="30" Margin="10,0" />
