动画符号-谷歌地图API

var line = new google.maps.Polyline({
    path: lineCoordinates,
    map: map,
    icons: [{
        icon: 'icons/cannon.png',
        offset: '100%'
    }]
});

问题是google.maps.Polyline只接受Symbol作为参数，而不接受图像。

然而，希望并没有完全消失。你有两个不同的动画选项。

(1)按照文档:

符号的路径，可以是内置的符号路径，也可以是自定义的路径使用SVG路径表示法表示。必需的。

然后用你在google api docs示例中使用的相同代码进行动画。

(2)动画标记，您已更改为您喜欢的图像。

Js的例子

还链接了下面代码的相关部分，请注意，我使用requestAnimationFrame来步进动画，因为它通常被认为是制作动画的最佳实践。

    // Next position of the marker (we use - 0.1 from previous position)
    marker.setPosition(new google.maps.LatLng(pos.lat(), pos.lng() - 0.1));
    // If we have reached the end of the path - cancel animationFrame
    if (steps === 99) {
      cancelAnimationFrame(requestID); 
      return;
    }
    // Increasing steps
    steps++;
  };
  // Start animation
  draw();
}    
// Init
google.maps.event.addDomListener(window, 'load', initialize);

同样，如果jsfiddle示例在某个时刻死亡:

HTML:页面的所有正常标签，加上这个:

<div id="map-canvas"></div>

CSS:

html, body {
  height: 100%;
}
#map-canvas {
    height:500px;
    width:500px;
}

另外，记得包含google maps JavaScript。:)

作为最后的注意事项，而不是做:

// Next position of the marker (we use - 0.1 from previous position)
marker.setPosition(new google.maps.LatLng(pos.lat(), pos.lng() - 0.1));

您也可以使用更复杂的路径，通过沿着从MVCarray接收的位置行走，您可以通过调用

从折线本身获得:

// Path for marker
path = route.getPath();

关于的完整示例在这个js小提琴示例中演示(注意:动画很快，因为示例在折线路径中只使用了11个LatLng位置)

欢呼。
