我已经动态生成了按钮。我想向此按钮添加click和onInputOver操作,但是只有click(chooseHero)
按钮有效:
编辑FULL_CODE
var heroesState = {
create: function() {
//game.add.image(0, 0, 'board');
backBtn = game.add.button(5, 5, 'back_btn', this.GoBack);
choiceText = game.add.bitmapText(150, 50, 'desyrel', 'Welcome warrior, Choose your Hero', 35);
//var heroCardStyle = { fill: "#00ff00" };
var initWidth = 60;
var initHeight = 150;
var heroesFiles = ["obatala.jpg", "obba.jpg", "olokun.jpg", "orunmila.jpg", "oshun.jpg",
"oxosi.jpg", "oya.jpg", "ozain.jpg", "shango.jpg", "yemoja.jpg"
];
var heroesLength = heroesFiles.length;
var heroCard = [];
//4 buttons generated dynamically with a loop
for (var i = 0; i < heroesLength / 2; i++) {
//longueur de chaque élément dans heroes
var ln = heroesFiles[i].length;
heroCard = game.add.button(initWidth, initHeight, heroesFiles[i].substring(0, ln - 4), this.ChooseHero, this.over);
heroCard.scale.setTo(0.5, 0.5);
heroCard.alpha = 0.4;
initWidth = initWidth + 150;
};
var initWidth = 60;
var initHeight = 350;
//4 buttons generated dynamically with a loop
for (var i = heroesLength / 2; i < heroesLength; i++) {
//longueur de chaque élément dans heroes
var ln = heroesFiles[i].length;
heroCard = game.add.button(initWidth, initHeight, heroesFiles[i].substring(0, ln - 4), this.ChooseHero, this.over);
heroCard.scale.setTo(0.5, 0.5);
heroCard.alpha = 0.4;
initWidth = initWidth + 150;
};
//heroCard.onInputOver.add(over, this);
},
//functions associated to button events(chooseChero works fine but over doesn't work)
GoBack: function() {
game.state.start("menu");
},
over: function() {
heroCard.tint = 0xffffff;
},
ChooseHero: function() {
//game.state.start("menu");
chosenHero = this.key;
alert(this.key);
game.state.start("play", true, false, chosenHero);
}
};
我收到此错误:无法读取未定义的属性'onInputOver'。
答案 0 :(得分:1)
从其他代码中,我可以看到以下问题:
game.add.button()
具有不同的签名。在the official docs中,我们可以看到它是:新按钮(游戏[,x] [,y] [,键] [,回调] [,callbackContext] [,overFrame] [,outFrame] [,downFrame] [,upFrame])
overFrame
,outFrame
,downFrame
和upFrame
都在寻找要在要使用的图形上使用的框架,而不是要调用的函数。
var heroCard = [];
用于初始化变量,但随后将其设置为实际按钮。我可能建议将其更改为heroCards
,然后在heroCard
循环中创建一个新的for
,在将其添加到heroCards
数组之前在其中定义其属性。
heroCard.onInputOver.add(over, this);
应该在您的for循环内。如果您console.log(arguments);
看到返回两个参数,则可以使用第一个参数来修改它们悬停的按钮:
over: function(heroCard) {
heroCard.tint = 0xffffff;
// This is a quick and dirty way to see what arguments are being passed
// to a function in JavaScript.
// console.log(arguments);
}
