游戏介绍
智能手机刚刚普及时,切水果这款小游戏可谓风靡一时。几年过去了,现在,让我们用纯JavaScript来实现这个水果忍者游戏,就算是为了锤炼我们的JavaScript开发技能吧。
《切水果》这款游戏的创意来源也非常简单,就是一位员工在家里看到电视播放销售水果刀的广告,为了体现出刀的锋利,广告里推销员把香蕉抛向空中,然后用水果刀在空中把香蕉切开。
经典模式(图标为西瓜):在经典模式中无时间限制,水果和炸弹会不断浮动出现在屏幕上。玩家共有三次因没有切到水果而失误的机会,而只要一切到炸弹游戏就会马上结束。每积累到100分就会自动补充一次以前失去的机会。此模式中会随机出现石榴(连切来加分,分数高低,取决于玩家切的速度)、火龙果(切掉可以+50分)和杨桃
开始游戏:用鼠标在网页上划一条横线切正中的“New Game”的西瓜开始新的游戏:

- 分开
ClassFruit.prototype.apart = function( angle ){
this.anims.clear();
this.image.hide();
this.shadow.hide();
this.aparted = true;
var inf = infos[ this.type ], preSrc = inf[0].replace( ".png", "" ), radius = this.radius;
var create = layer.createImage.saturate( layer, this.startX - radius, this.startY - radius, inf[1], inf[2] );
angle = ( ( angle % 180 ) + 360 + inf[4] ) % 360;
this.bImage1 = create( "fruit", preSrc + "-1.png" );
this.bImage2 = create( "fruit", preSrc + "-2.png" );
[ this.bImage1, this.bImage2 ].invoke( "rotate", angle );
this.apartAngle = angle;
timeline2.createTask({
start: 0, duration: dropTime, object: this,
onTimeUpdate: this.onBrokenDropUpdate, onTimeStart: this.onBrokenDropStart, onTimeEnd: this.onBrokenDropEnd,
recycle: this.anims
});
};
- 抛出
ClassFruit.prototype.shotOut = function(){
var sign = [ -1, 1 ];
return function( start, endX ){
this.shotOutStartX = this.originX;
this.shotOutStartY = this.originY;
this.shotOutEndX = average( this.originX, endX );
this.shotOutEndY = min( this.startY - random( this.startY - 100 ), 200 );
this.fallOffToX = endX;
timeline.createTask({
start: start, duration: dropTime, object: this,
onTimeUpdate: this.onShotOuting, onTimeStart: this.onShotOutStart, onTimeEnd: this.onShotOutEnd,
recycle: this.anims
});
if( this.type != "boom" )
this.rotate( 0, ( random( 180 ) + 90 ) * sign[ random( 2 ) ] );
return this;
};
}();
- 掉落
ClassFruit.prototype.fallOff = function(){
var sign = [ -1, 1 ];
var signIndex = 0;
return function( start, x ){
if( this.aparted || this.brokend )
return ;
var y = 600;
if( typeof x !== "number" )
x = this.originX + random( dropXScope ) * sign[ ( signIndex ++ ) % 2 ];
this.fallTargetX = x;
this.fallTargetY = y;
timeline.createTask({
start: start, duration: dropTime, object: this,
onTimeUpdate: this.onFalling, onTimeStart: this.onFallStart, onTimeEnd: this.onFallEnd,
recycle: this.anims
});
}
}();
资源下载
- CSDN下载:
彩蛋
- 改变水果:找到文件夹
images/fruit
,直接替换图片,不要修改名称。如sandia,此处sandia.png
代表完整的西瓜,sandia-1.png
和sandia-2.png
代表被切开的西瓜,注意替换的图片对应,否则影响观赏效果 - 修改音效:可在
sound
文件夹替换音频(什么都可以) - 手动开挂:找到
all.js
文件,修改number==3
,可改成任意整数数字,具体位置如图所示
- 防切炸弹:只需要修改sliceAt函数,如下图if ( fruit.type != "boom")
的红色框就是切到水果的分支,执行加分和显示水果被切成两半的效果。else的蓝色框是切到炸弹的分支,我们只需要将蓝色框内的代码注释掉,游戏就永远不能结束了
总结
游戏介绍就到这里,学习的过程就是认识自己的过程,在开发中不断补充自己的知识,增加自己的理解,弥补不足,有一定的JavaSript水平的朋友,可以看看源代码,相信你的JavaSript水平会有很大的提升。
