问题描述

我有一个图像和按钮网格，我想自动为从一个位置到另一个位置(实际上是左边几个空格)的运动设置动画，但它没有奏效.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！！！

I have a grid of images and buttons, and I want to animate motion from one position to another (actually a few spaces to the left) automatically, but it hasn't worked. I've tried using a storyboard in xaml and programatically as in the code below, but its now working. Please help!!!

    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);
    }

推荐答案

完全 TranslateTransform 不适合你想要的.更好地使用思维动画

totally TranslateTransform isnt good for that you want .better to use thinkness animation

我建议你不要使用画布并将其更改为网格，但如果你使用画布，请使用此代码

i advise you dont use canavas and change it to grid but if you use canavas use this code

 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:

if you use grid code is this :

 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很好！

you can use opacity animation for fade your grid ... it show good if move and fade !

    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，并且更好地使用 TranslateTransform 来调整控件的大小，例如此代码下方的代码，如果鼠标进入，则调整控件的大小:

if there isnt any reason u can change canavas to grid and also better use TranslateTransform for resize controls like code below this code resize control if mouse enter in it :

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，如缩放变换:)

if you animation for width or height do same work like scale transform :)
