LayaAir飞机大战-6

1. 增加难度条件,实现积分达到条件后进入新关卡的逻辑

onLoop():void{

//检测碰撞

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

//获取角色对象1

var role1:Role = this.roleBox.getChildAt(i) as Role;

if(role1.hp<1)continue;

for(var j:number = i-1;j>-1;j--){

//如果角色已经死亡，则忽略

if(!role1.visible)continue;

//获取角色对象2

var role2:Role = this.roleBox.getChildAt(j) as Role;

//如果角色未死亡，并且阵营不同才能进行碰撞

if(role2.hp>0 && role1.camp != role2.camp){

//计算碰撞区域

var hitRadius:number = role1.hitRadius + role2.hitRadius;

//根据距离判断是否碰撞

if(Math.abs(role1.x - role2.x) < hitRadius && Math.abs(role1.y - role2.y) < hitRadius){

//碰撞之后掉血

this.lostHp(role1,1);

this.lostHp(role2,1);

//每掉一滴血，积分+1

this.score ++;

//在UI上显示积分

this.gameInfo.score(this.score);

//积分大于升级积分，则升级

if(this.score > this.levelUpScore){

//升级关卡

this.level ++;

//在UI上显示等级

this.gameInfo.level(this.level);

//提高下一级的升级难度

this.levelUpScore+=this.level * 5;

}

}

}

}

}

}

1. 关卡难度提升后,实现敌方血量,数量,速度提升的逻辑

//关卡越高，创建敌机间隔越短

var cutTime:number = this.level < 30 ? this.level * 2 : 60;

//关卡越高，敌机飞行速度越快

var speedUp:number = Math.floor(this.level / 6);

//关卡越高，敌机血量越高

var hpUp:number = Math.floor(this.level / 8);

//关卡越高，敌机数量越多

var numUp:number = Math.floor(this.level / 10);

//生成小飞机

if(Laya.timer.currFrame % (80 - cutTime ) === 0){

this.createEnemy(0,2+numUp,3+speedUp,1);

}

//生成中型飞机

if(Laya.timer.currFrame % (150 - cutTime * 4) === 0){

this.createEnemy(1,1+numUp,2+speedUp,2+hpUp*2);

}

//生成boss

if(Laya.timer.currFrame % (900 - cutTime * 4) === 0){

this.createEnemy(2,1,1+speedUp,10+hpUp *6);

//播放boss出场声音

Laya.SoundManager.playSound("res/sound/enemy3_out.mp3");

}
