如何创建鼠标跟随元素，延迟和基于方向？

Question

我正在寻找一种解决方案，让图像跟踪鼠标光标的方向。基于https://codepen.io/redspiderfish/pen/MYmeYz我处理了这个代码：https : //jsfiddle.net/h78wm1nz/尝试使用基于http://jsfiddle.net/dPDF3的以下代码添加旋转。但是蜜蜂看起来醉了。 var img = $('#wunderbiene img');//if (img.length > 0) {var offset = img.offset();function beeMouse(evt) {  var center_x = (offset.left) + (img.width() / 2);  var center_y = (offset.top) + (img.height() / 2);  var mouse_x = evt.pageX;  var mouse_y = evt.pageY;  var radians = Math.atan2(mouse_x - center_x, mouse_y - center_y);  var degree = (radians * (180 / Math.PI) * -1) + 180;  img.css('-moz-transform', 'rotate(' + degree + 'deg)');  img.css('-webkit-transform', 'rotate(' + degree + 'deg)');  img.css('-o-transform', 'rotate(' + degree + 'deg)');  img.css('-ms-transform', 'rotate(' + degree + 'deg)');}//}$(window).mouseenter(function() {  $(document).mousemove(beeMouse);}).mouseleave(function() {  $(document).unbind();});
