LayaAir飞机大战-3

1. 新增资源并制作飞机的动画

/**

* 角色类

*/

class Role extends Laya.Sprite {

//定义飞机的身体

private body:Laya.Animation;

//是否缓存了动画.

private static cached:boolean = false;

//角色类型

public type:string;

//阵营

public camp:number;

//血量

public hp:number;

//速度

public speed:number;

//被击半径

public hitRadius:number;

constructor() {

super();

//初始化

// this.init();

}

public init(_type:string,_camp:number,_hp:number,_speed:number,_hitRadius:number):void{

//缓存了无需重复缓存

if(!Role.cached){

Role.cached = true;

//缓存飞行动画

Laya.Animation.createFrames(["war/hero_fly1.png","war/hero_fly2.png"],"hero_fly");

//缓存击中爆炸效果

Laya.Animation.createFrames(["war/hero_down1.png","war/hero_down2.png"

,"war/hero_down3.png","war/hero_down4.png"],"hero_down");

//缓存敌机1飞行动画

Laya.Animation.createFrames(["war/enemy1_fly1.png"],"enemy1_fly");

//缓存敌机1爆炸动作

Laya.Animation.createFrames(["war/enemy1_down1.png","war/enemy1_down2.png","war/enemy1_down3.png",

"war/enemy1_down4.png"],"enemy1_down");

//缓存敌机2飞行动画

Laya.Animation.createFrames(["war/enemy2_fly1.png"],"enemy2_fly");

//缓存敌机2爆炸动作

Laya.Animation.createFrames(["war/enemy2_down1.png","war/enemy2_down2.png","war/enemy2_down3.png",

"war/enemy2_down4.png"],"enemy2_down");

//缓存敌机2碰撞动作

Laya.Animation.createFrames(["war/enemy2_hit.png"],"enemy2_hit");

//缓存敌机3飞行动画

Laya.Animation.createFrames(["war/enemy3_fly1.png","war/enemy3_fly2.png"],"enemy3_fly");

//缓存敌机3爆炸动作

Laya.Animation.createFrames(["war/enemy3_down1.png","war/enemy3_down2.png","war/enemy3_down3.png",

"war/enemy3_down4.png","war/enemy3_down5.png","war/enemy3_down6.png"],"enemy3_down");

//缓存敌机3碰撞动作

Laya.Animation.createFrames(["war/enemy3_hit.png"],"enemy3_hit");

}

//创建了无需重复创建

if(!this.body){

//创建一个动画作为飞机的身体

this.body = new Laya.Animation();

//把机体添加到容器内

this.addChild(this.body);

}

//播放飞机动画

this.playAction("fly");

}

}

1. 修改播放动画到逻辑,改为根据类型播放相应到动画

playAction(action:string):void{

//根据类型播放动画

this.body.play(0,true,this.type+"_"+action);

//获取动画大小区域

var bound:Laya.Rectangle = this.body.getBounds();

//设置机身居中

this.body.pos(-bound.width/2,-bound.height/2);

}

1. 随机创建敌人添加到舞台上

//敌机血量

private hps:Array = [1,2,2];

//敌机速度

private speeds:Array = [3,2,1];

//敌机被击半径

private radius:Array = [15,30,70];

createEnemy(type:number,num:number,speed:number,hp:number):void{

for(var i:number = 0;i

//随机出现敌人

var r:number = Math.random();

//根据随机数，随机敌人

var type:number = r<0.7?0:r<0.95?1:2;

//创建敌人

var enemy:Role = Laya.Pool.getItemByClass("role",Role);

//初始化角色

enemy.init("enemy"+(type+1),1,hp,speed,this.radius[type]);

//随机位置

enemy.pos(Math.random()*400+40,-Math.random()*200 - 100);

//添加到舞台上

this.roleBox.addChild(enemy);

}

}

1. 优化角色创建并实现飞机移动

onLoop():void{

//遍历舞台上所有的飞机，更改飞机的状态

for(var i:number = this.roleBox.numChildren-1;i>-1;i--){

var role:Role = this.roleBox.getChildAt(i) as Role;

if(role && role.speed){

//根据飞机速度改变位置

role.y+=role.speed;

//如果敌机移动到显示区域外则移除

if(role.y>1000 || !role.visible || (role.isBullet && role.y<-20)){

//从舞台移除

role.removeSelf();

}

}

// //每隔30帧创建新的敌机

 if(Laya.timer.currFrame%60 === 0){

测试

 this.createEnemy(2,1,3,1);

 }

}
