 //出敌人
	initEnemy : function(){
		
		if(Game.missionLazy > 0){
			
			Game.missionLazy -= 20;
			
			return false;
		}
		
		if(Game.enemyLazy > 0){
			
			Game.enemyLazy -= 20;
			
			return false;
		}
		else{
			
			Game.enemyLazy = Game.enemyTime;
		}
		
		if(Game.missionEnemy > 20){
			
			Game.missionEnemy = 1;
			
			Game.mission += 1;
			Info.updateMission();
			
			Game.missionLazy = Game.missionTime;
			
			if(Game.mission >= 20){
				
				Game.initEnemy = function(){
					
					if(Game.enemyList.length <= 0)Game.win();
				};
				return false;
			}
			
			return false;
		}
		
		Game.missionEnemy += 1;
		//新增一个敌人
		var enemy = new Enemy(Game.canvasList.main,Game.imgList.enemy_img,Game.mission,55,0,40,40);
		enemy.num = Game.mission*20+Game.missionEnemy;
		
		Game.enemyList.push(enemy);
