【百行代码说游戏】ActionScript3.0 小游戏【劲舞团】源码+演示-优快云博客

最近学ActionScript3.0 以下为自己写的一个小游戏。尽量以最少的代码，实现功能

游戏原理：看代码注释

游戏规则：类似于【劲舞团】游戏，玩家可以按UP,DOWN,LEFT,RIGHT键来操控游戏。

打掉相应的箭头则得分，否则失手。

箭头落到底线没有被打掉，则为失手。

失手10次，游戏结束。

得分过30，升一级。难度加大。

先建一个箭头的类Baby.as 。提供四种不同造型的箭头

package { import flash.display.Sprite; import flash.filters.ConvolutionFilter; /** * ... * @author kkkloveyou */ public class Baby extends Sprite { private var color:uint = 0xFFFFFF; private var direction:uint; private const LEFT:uint = 37; private const RIGHT:uint = 39; private const UP:uint = 38; private const DOWN:uint = 40; public var flag:int = 0; public function Baby(direction:uint):void { this.direction = direction; switch (direction) { case LEFT: drawLeft(); break; case RIGHT: drawRight(); break; case UP: drawUp(); break; case DOWN: drawDown(); break; default: break; } } public function drawRight():void { graphics.lineStyle(3,0xff0000);//左面 graphics.moveTo(-60,-30); graphics.lineTo(-60,30); graphics.lineTo(30, 30); graphics.lineTo(30,40); graphics.lineTo(60, 0); graphics.lineTo(30,-40); graphics.lineTo(30, -30); graphics.lineTo( -60, -30); flag = 39; } public function drawLeft():void { graphics.lineStyle(3,0x00ff00);//右面 graphics.moveTo(60,-30); graphics.lineTo(60,30); graphics.lineTo(-30, 30); graphics.lineTo(-30,40); graphics.lineTo(-60, 0); graphics.lineTo(-30,-40); graphics.lineTo(-30, -30); graphics.lineTo(60, -30); flag = 37; } public function drawUp():void { graphics.lineStyle(3,0x00ffff);//上面 graphics.moveTo(-30,60); graphics.lineTo(30,60); graphics.lineTo(30, -30); graphics.lineTo(40,-30); graphics.lineTo(0, -60); graphics.lineTo(-40,-30); graphics.lineTo(-30, -30); graphics.lineTo( -30, 60); flag = 38; } public function drawDown():void { graphics.lineStyle(3,0x001177);//下面 graphics.moveTo(-30,-60); graphics.lineTo(30,-60); graphics.lineTo(30, 30); graphics.lineTo(40,30); graphics.lineTo(0, 60); graphics.lineTo(-40,30); graphics.lineTo(-30, 30); graphics.lineTo( -30, -60); flag = 40; } } }再建一个控制类Main.as 用来控制游戏package { import flash.display.Sprite; import flash.events.Event; import flash.events.KeyboardEvent; import flash.text.TextField; import flash.text.TextFormat; import flash.ui.Keyboard; public class Main extends Sprite { public var arr:Array;//储存下落箭头的数组 public var time:uint; public var errorTxt:TextField;//错误显示文本 public var trueTxt:TextField;//正确显示文本 public var levelTxt:TextField;//等级文本 public var meTxt:TextField;//作者文本 public var errorCount:int = 0;//错误总计变量 public var trueCount:int = 0;//正确总计变量 public var levelCount:int = 1;//当前关卡等级 public var speed:uint = 5; //箭头移动速度 public function Main(){ init(); } public function init():void{ this.addEventListener(Event.ENTER_FRAME,loopHandler); stage.addEventListener(KeyboardEvent.KEY_DOWN,downHandler); arr = new Array(); time = 0; errorTxt = new TextField(); trueTxt = new TextField(); levelTxt = new TextField(); meTxt = new TextField(); errorTxt.text = "失手: "+errorCount; trueTxt.text = "得分: " + trueCount; levelTxt.text = "等级: " + levelCount; meTxt.text = "卫哥作品"; levelTxt.x = 50; levelTxt.y = 50; errorTxt.x = 50; errorTxt.y = 150; trueTxt.x = 50; trueTxt.y = 250; meTxt.x = 700; meTxt.y = 550; this.addChild(errorTxt); this.addChild(trueTxt); this.addChild(levelTxt); this.addChild(meTxt); } public function downHandler(event:KeyboardEvent):void{ errorCount++; if (errorCount >= 10) { stage.removeEventListener(KeyboardEvent.KEY_DOWN, downHandler); this.removeEventListener(Event.ENTER_FRAME,loopHandler); } for(var i:Number = arr.length-1;i>=0;i--){ //判断键盘按下的键值是否和场景里的字母符合.如果符合则消去 var baby:Baby = arr[i] as Baby; if ( baby ){ if(baby.flag == event.keyCode){ this.removeChild(arr[i]); arr.splice(i,1); trueCount++; errorCount--; break; } } } if (trueCount >= 30) { levelCount++; //级数升级，得手清零 speed += 3; //级数升级，速度增大,难度增大 trueCount = 0; } errorTxt.text = "失手: "+errorCount; trueTxt.text = "得分: " + trueCount; levelTxt.text = "等级: " + levelCount } public function loopHandler(event:Event):void{ time++; if(time>=10){ time = 0; var baby:Baby = new Baby(int(Math.random() * 4) + 37); //随机产生箭头类型 baby.x = stage.stageWidth / 2; baby.y = 30; this.addChild(baby); arr.unshift(baby); } for(var i:Number = arr.length-1;i>=0;i--){ arr[i].y+=speed; //箭头速度 if(arr[i].y>=stage.stageHeight){ this.removeChild(arr[i]); arr.splice(i,1); errorCount++; errorTxt.text = "失手: "+errorCount; break; } } if (errorCount >= 10) { stage.removeEventListener(KeyboardEvent.KEY_DOWN, downHandler); this.removeEventListener(Event.ENTER_FRAME,loopHandler); } } } }
