如何用js寫一個簡單的迷宮和打地鼠遊戲

qq_夢裡輕煙發表於2020-10-24

最近剛學JavaScript,就用學的知識寫了兩個充滿童年回憶的小遊戲–迷宮和打地鼠,現在讓我們一起來看看怎麼實現吧~

1.簡單迷宮

這是一個不能再簡單的迷宮了,遊戲規則:從迷宮中走到終點就贏了;碰牆就輸;從地圖外走到終點算作弊。S為起點,E為終點。

js程式碼

var isStart = false;
var isInMap = false;
window.onload = function () {
    var wall = document.getElementsByClassName("wall");
    /*start */
    document.getElementById("start").addEventListener("mouseover", function () {
        document.getElementById("result").textContent = "";
        isStart = true;
        isInMap = true;
        for (var i = 0; i < wall.length; i++) { wall[i].style.backgroundColor = "#EEEEEE"; }

    })

    /*out of the map */
    document.getElementById("wholeMaze").addEventListener("mouseleave", function () {
        isInMap = false;
    });
    /*wall */
    for (var i = 0; i < wall.length; i++)
        wall[i].addEventListener("mouseover", function (event) {
            if (isStart) {
                event.target.style.backgroundColor = "#FF0000";
                document.getElementById("result").textContent = "You hit the wall, lost the game!";
                isStart = false;
            }
        });
    for (var i = 0; i < wall.length; i++)
        wall[i].addEventListener("mouseleave", function (event) {
            event.target.style.backgroundColor = "#EEEEEE";
        });
    /*end */
    document.getElementById("end").addEventListener("mouseover", function () {
        if (isStart) {
            if (isInMap) { document.getElementById("result").textContent = "Congratulation! You win the game!"; }
            else {
                document.getElementById("result").textContent = "Oh, my friend, please don't cheat!";
                isStart = false;
            }
        }
        isStart = false;
    });
}

js部分的關鍵在於給元素新增Listener,相當於附加個觸發器,一旦事件發生如“mouseleave”(滑鼠離開對應元素區域)就呼叫對應的函式。另外注意物件導向程式設計。

2.打地鼠

這個遊戲比較複雜,也比較有意思,加上了計時和計分功能,還可以控制遊戲的開始和結束並顯示遊戲狀態。遊戲結束時彈出結果。
遊戲規則:打中地鼠加一分,打錯扣一分,不打分不變,玩家可以挑戰30秒內能打中多少隻地鼠。(拼手速的時刻到了~)

由於程式碼有點長,這裡小編就不附上了。詳見:https://gitee.com/Hometown2020/mole

3.遊戲連結

看了程式碼,接下來就是體驗遊戲了,這裡小編附上自己的遊戲連結,有興趣的朋友可以體驗一下~

  1. 迷宮
  2. 打地鼠

PS:如果你對開發小遊戲感興趣又不想打碼的話,推薦一個對新手很友好的開發平臺construct3,這裡小編寫了一個簡單的植物大戰殭屍塔防版,有興趣的瞭解一下~
