【百行代码说游戏】ActionScript3.0 小游戏【劲舞团】源码+演示

不念不忘少年蓝@ 2022-04-17 04:15 126阅读 0赞

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);
    			}
    		}
    	}
    }
