文本框碰撞测试

 1.核心代码:

// 初始化舞台和变量
var stage, textField, bounds, velocity;function init() {// 创建舞台stage = new createjs.Stage("canvas");// 设置矩形边界bounds = {x: 50, y: 50, width: 400, height: 300};// 绘制边界矩形var border = new createjs.Shape();border.graphics.beginStroke("#000000").drawRect(bounds.x, bounds.y, bounds.width, bounds.height);stage.addChild(border);// 创建文本框textField = new createjs.Text("碰撞测试", "20px Arial", "#000000");textField.textAlign = "center";textField.textBaseline = "middle";// 设置文本框初始位置（随机在边界内）textField.x = bounds.x + Math.random() * bounds
