我剛剛開始使用EaselJS,並且正在進入我的第一個障礙。我已經擴展容器對象,以創建一個新類叫蛋:EaselJS打勾事件delta屬性未傳播給兒童
(function() {
var Egg = function(color, x, y, cY) {
this.initialize(color, x, y, cY);
}
var e = Egg.prototype = new createjs.Container(); // inherit from Container
e.Container_initialize = e.initialize;
e.initialize = function(color, x, y, cY) {
this.Container_initialize();
this.circle = new createjs.Shape();
this.circle.graphics.beginFill(color).drawCircle(0, 0, 10);
this.circle.x = x;
this.circle.y = y;
this.addChild(this.circle);
this.changeY = cY;
this.addEventListener("tick", this.handleTick);
}
e.handleTick = function(event) {
console.log(event.delta); // undefined!
}
window.Egg = Egg;
}());
而且我初始化這樣的:
var stage, timeCircle;
function init() {
stage = new createjs.Stage("gameCanvas");
timeCircle = new createjs.Shape();
createjs.Ticker.useRAF = true;
createjs.Ticker.setFPS(30);
createjs.Ticker.addEventListener("tick", tick);
var egg = new Egg("red", 50, 50, 100);
stage.addChild(egg);
var egg2 = new Egg("blue", 100, 50, 50);
stage.addChild(egg2);
}
function tick(event) {
stage.update(event);
}
雞蛋handleTick功能,當我註銷event.delta財產,我得到「未定義」。我認爲如果我通過stage.update調用傳遞事件,那麼它會傳播到舞臺上的對象?
啊,我聽不懂的事件參數如何傳遞給一DisplayObject作爲「PARAMS」 - 謝謝! – koosa
作爲任何人絆倒到這個答案的後續行動:EaselJS v0.8.0現在公開顯示列表滴答事件的'delta'以避免這種混淆。 – gskinner
