Question

我正在创建一个演示应用程序，在单击按钮时随机选择一个场地。单击按钮后，我希望在选择场地之前使用CSS3和jQuery通过老虎机旋转动画来滚动场地。

我考虑过使用-webkit-keyframes并改变背景位置，但这不是我想要的理想动画。

@-webkit-keyframes spin{  
  0% {  
        background-position: 0, 0 0;
        -webkit-transform: rotateX(0deg);
     }
  100% { 
        background-position: 0, 0 -640px;
        -webkit-transform: rotateX(360deg);
     }
}

.rotating{
    -webkit-animation: spin .5s infinite linear;
    -webkit-transition: background-position .7s;
}

任何人都可以就如何实现这一目标提供任何见解吗？ Here是我到目前为止所拥有的。任何帮助表示赞赏。

谢谢

Answer 1

经过多次研究抄袭后，我想出了这个。希望它有某种形式或形式。

const POSTERS_PER_ROW = 12;
const RING_RADIUS = 200;

function setup_posters(row) {
  var posterAngle = 360 / POSTERS_PER_ROW;
  for (var i = 0; i < POSTERS_PER_ROW; i++) {
    var poster = document.createElement('div');
    poster.className = 'poster';
    // compute and assign the transform for this poster
    var transform = 'rotateY(' + (posterAngle * i) + 'deg) translateZ(' + RING_RADIUS + 'px)';
    poster.style.webkitTransform = transform;
    // setup the number to show inside the poster
    var content = poster.appendChild(document.createElement('p'));
    content.textContent = i;
    // add the poster to the row
    //row.appendChild(poster);
  }

}

function init() {
  setup_posters(document.getElementById('ring-1'));
  setup_posters(document.getElementById('ring-2'));
  setup_posters(document.getElementById('ring-3'));
}

// call init once the document is fully loaded
window.addEventListener('load', init, false);

<h1>//BOTCHED Poster Circle</h1>
<strike>
    <p>//This is a simple example of how to use CSS transformation and animations to get interesting-looking behavior.</p>
    <p>The three rings are constructed using a simple JavaScript function that creates elements and assigns them a transform
      that describes their position in the ring. CSS animations are then used to rotate each ring, and to spin the containing
      element around too.</p>
    <p>Note that you can still select the numbers on the ring; everything remains clickable.</p>

Answer 2

使用http://odhyan.com/slot/插件的http://odhyan.com/slot/怎么样。

我不确定您使用旋转的关键帧方法是否会产生所需的效果。老虎机显示器旋转，但由于它具有大直径，它看起来更像是连续滚动。您需要扭曲图像的顶部和底部，以使它们看起来更逼真。

如果模糊顶部和底部（透明gif或css3缩进阴影），您可能会接近所需的效果。查看video of a real slot machine

Answer 3

如果你对这里的其他一些答案不满意，我会考虑采用另一种（希望更简单）的方法。

创建一个垂直的图像条（或div），最顶层的图像是您想要停止的图像。
使用jquery的.animate()方法在较小的容器div中垂直移动它们，overflow属性设置为hidden。效果将是你一次只能看到一个'旋转'。如果你快点做，我觉得它看起来很好。
玩动画计时，直到你看到逼真的东西。如果你需要让它看起来更酷，你可以在容器中添加一些渐变png叠加来模拟3d深度。

这不是一个超现代的CSS3解决方案，但它看起来不错。我找不到一个js例子，但this Flash one使用相同的想法。这里没有3D;只是垂直移动的图像。它有点模糊，但它看起来仍然很酷。 PS我讨厌闪光灯。

Answer 4

在我看来，javascript + trigonometry是你最好的选择。看看这个dynamic carousel并切换轴，我想这就是你正在寻找的效果。

如何用CSS3和＆amp ;;实现老虎机旋转效果？ jQuery的？
