對於大學我必須做一個MVC風格編碼的JavaScript遊戲。 (模型,視圖,控制器)。我對此很新,所以請不要太難。我收到以下錯誤:「Uncaught TypeError:無法讀取未定義的屬性」getData「。有人可以幫我找出問題嗎?我敢肯定我的代碼充滿了錯誤。我試圖讓玩家模型在畫布上繪製。任何和所有的幫助,將不勝感激!這裏是我的代碼:爲什麼我的'getData'函數不能被我的代碼訪問?
var GOBLINS = GOBLINS || {};
GOBLINS.View = function() {};
GOBLINS.View.prototype.draw = function(objects) {
for(i=0; i < objects.length; i++) {
ctx.drawImage(objects[i],0,0);
};
};
GOBLINS.View.prototype.update = function(data){
this.draw(data);
};
GOBLINS.Model = function() {
this.data = [];
};
GOBLINS.Model.prototype.player = {
hitPoints: 25,
x: 15,
y: 20,
img: new Image(),
push: function() {
data.push(GOBLINS.Model.player.img);
}
};
GOBLINS.Model.prototype.getData = function(recall){
recall(this.data);
};
GOBLINS.Controller = function() {
var M = new GOBLINS.Model();
var V = new GOBLINS.View();
this.mainLoop();
};
GOBLINS.Controller.prototype.mainLoop = function() {
var self = this;
this.M.getData(function(data){
self.V.update(data);
});
window.requestAnimationFrame(function(){
self.mainLoop();
});
};
window.onload = function() {
var game = new GOBLINS.Controller();
GOBLINS.Model.player.img.src = "Image/Player.png";
var c=document.getElementById("gameCanvas");
var ctx=c.getContext("2d");
};
太謝謝你了。我錯誤地寫下了教師代碼。 –
