用FLASH 做壹個 小遊戲
壹個長方形可以按A或者D左移右移，在遊戲開始會監聽鍵盤事件，圓形在舞臺下面往上跑，如果長方形碰到圓，遊戲結束，就這麽簡單。看代碼myGame.as，妳可以新建壹個Fla文件，然後以myGame.as為文檔類：
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.display.*;
import flash.events.*;
import flash.text.TextField;
public class myGame extends MovieClip{
public const State_init=1;
public const State_play=2;
public const State_over=3;
public var gamestate:uint=0;
public var success:uint=0;
public var fail:int=0;
public var player1:Sprite=new Sprite();
public var player2:Sprite=new Sprite();
public function myGame(){
player1.graphics.beginFill(0xFF0000);
player1.graphics.drawRect(100,100,20,10);
player1.graphics.endFill();
player2.graphics.beginFill(0);
player2.graphics.drawCircle(200,400,10);
player2.graphics.endFill();
stage.addChild(player1);
stage.addChild(player2);
//默認會初始化構造函數，添加監聽當前的遊戲狀態
stage.addEventListener(Event.ENTER_FRAME,gameloop);
//初始化遊戲狀態，要不gamestate=0;
gamestate=State_init;
// constructor code
}
public function gameloop(e:Event):void{
switch(gamestate) {
case State_init:
initGame();
break;
case State_play:
playGame();
break;
case State_over:
gameOver();
break;
}
}
public function initGame():void{
stage.addEventListener(KeyboardEvent.KEY_DOWN,action);
success=0;
fail=0;
gamestate=State_play;
}
public function action(e:KeyboardEvent):void{
if(e.keyCode==65){
trace(e.keyCode);
player1.x-=2;
}else if(e.keyCode==68){
player1.x+=2;
}
if(player1.hitTestObject(player2)){
gameOver();
trace("you win!");
}
}
public function playGame():void{
player2.y-=4;
}
public function gameOver():void{
stage.removeEventListener(KeyboardEvent.KEY_DOWN,action);
gamestate=0;
trace("game over");
}
}
