var stage = new Kinetic.Stage({
container: 'container',
width: 578,
height: 200
});
var layer = new Kinetic.Layer();
var imageObj = new Image();
imageObj.onload = function() {
var yoda = new Kinetic.Image({
x: 200,
y: 50,
image: imageObj,
width: 106,
height: 118
});
// add the shape to the layer
layer.add(yoda);
// add the layer to the stage
stage.add(layer);
};
imageObj.src = 'http://www.html5canvastutorials.com/demos/assets/yoda.jpg';
var amplitude = 150;
var period = 2000;
// in ms
var centerX = stage.getWidth() / 2;
var anim = new Kinetic.Animation(function(frame) {
yoda.setX(amplitude * Math.sin(frame.time * 2 * Math.PI / period) + centerX);
}, layer);
anim.start();
一旦页面加载,我将如何让 yoda 图像从左到右进行动画处理,比如 50px?是否也可以通过缓动来做到这一点?对画布非常陌生,感谢您的帮助。这会更适合留给jQuery吗?
