Javascript createjs:Shape在单击时神秘地移动
我不熟悉HTML5和JavaScript。我正在做一个非常简单的“画布”项目,在这个项目中,你有两个试管,点击其中一个可以降低它的水平,增加另一个的水平 我已经编写了代码来实现这一点,它是有效的,唯一的问题是,当我点击试管时,它在屏幕上呈对角线移动,我不知道是什么导致了它 如果您能通读代码并告诉我问题出在哪里,那就太好了: TestTube.jsJavascript createjs:Shape在单击时神秘地移动,javascript,html,easeljs,createjs,Javascript,Html,Easeljs,Createjs,我不熟悉HTML5和JavaScript。我正在做一个非常简单的“画布”项目,在这个项目中,你有两个试管,点击其中一个可以降低它的水平,增加另一个的水平 我已经编写了代码来实现这一点,它是有效的,唯一的问题是,当我点击试管时,它在屏幕上呈对角线移动,我不知道是什么导致了它 如果您能通读代码并告诉我问题出在哪里,那就太好了: TestTube.js TestTube.prototype.render = function(){ this.graphics.clear(); t

这是因为您首先移动到(x,y): 然后再次将(x,y)添加到绘图调用:
this.graphics.lineTo(this.x,this.y+(this.height-this.width/2)); // etc
您只想添加(x,y)一次。但我只是在这里添加值;我没有给'this.y'或'this.y'赋值
