6.  游戏介绍  
    1.1 游戏方法  
    移动鼠标控制屏幕上的小鱼，需要躲避飞来的各种物体(下称"子弹")。若吃到钻石，可以随机获得一种特殊能力。游戏并没有尽头，设有8个level，难度依次递增。开始时小鱼共有五条生命，当这些生命耗尽时游戏结束。  
    1.2 子弹介绍  
    玩家在游戏中共会遇到四种子弹，下面逐一介绍其特性(括号内为其在代码中的代号):  
    ① 小泡泡(ball): 半径为4~5.2像素，颜色为\#eef的圆形，在屏幕右侧边界随机生成，运动方向为左方±5°，速度适中，密度大，较容易躲避，每个level都会出现。  
    ② 大泡泡(bigBall): 半径为40~48像素，颜色为\#eef的圆形，运动特性与小泡泡相同，但速度略慢，密度低，躲避难度中等，在2、5、6、MAX等级出现。  
    ③ 蝴蝶(butterfly): 看起来很大的一种子弹，但实际判定点为中心的一个圆形，半径为8像素，蝴蝶的颜色使用一定规则随机生成，路径为圆弧，速度快，密度低，躲避难度高，在3、6、7、MAX等级出现。  
    ④ 星星(star): 黄色的六角星，判定点是半径为6的圆形，路径为直线，但方向为追踪小鱼的方向，速度快，密度中等，躲避难度高，在4、5、7、MAX等级出现。  
    1.3 小鱼介绍  
    小鱼(plane)是一个红色的多边形，眼睛为黑色圆形，尾部可摆动，身后会出现水波纹，以上特点在下文中将详细说明。本文转载自http://www.biyezuopin.vip/onews.asp?id=14793除此之外，小鱼的中弹判定点是和小泡泡大小相近的圆形。  
    1.4 技能介绍  
    游戏过程中共可随机获得六种技能，现列举如下:  
    ① Score++ (func\_addScore): 分数随机增加3000~6000。  
    ② Speed Down (func\_slow): 将当前屏幕的子弹和即将出现的子弹速度减半，一个重要细节是子弹的生成速度也将减半，否则全屏幕将充满先前的子弹。  
    ③ 1 UP (func\_oneUp): 生命值加一。  
    ④ Superfish (func\_wudi): 无敌6000毫秒，此期间小鱼出现保护罩，同时闪烁。  
    ⑤ Big Bomb (func\_clear): 清除当前屏幕的子弹。  
    ⑥ Mini World (func\_small): 除了小泡泡外的三种子弹以及小鱼，外观与判定点的尺寸均减半。
7.  设计思路  
    2.1 游戏类型设计  
    经过一下午的思考，我们决定制作一款弹幕射击类游戏。在最初的版本中，玩家控制的对象被设计为飞机形状，机头可以朝向各个方位，子弹也被设计成随机位置与随机方向，此外，飞机本身也可进行射击。但这样一来，游戏的结构混乱，可玩性很低，我们便将其类型定位为横版弹幕躲避类游戏，同时也将飞机换成了小鱼的形状。
