简单代码如下
(function(){ let Bird=function(){ this.x=(game.canvas.width-48)/2;//鸟默认居中 this.y=(game.canvas.height)*(1-0.618);//小鸟的默认位置垂直为0.618 this.changeY=0//改变的值 this.changeRad=0; this.img=[game.allImg["bird0_0"],game.allImg["bird0_1"],game.allImg["bird0_2"]]; this.status="moveDown"; this.Wing=0;//图片的位置 控制翅膀的上下 }; window.Bird=Bird; Bird.prototype.update=function(){ if (this.status=="moveDown") { this.changeY+=0.6; this.y+=this.changeY; this.changeRad+=0.05; }else if(this.status=="moveUp"){ this.changeY-=0.8; if (this.changeY<=0) { this.status="moveDown"; return; } this.y-=this.changeY; this.y<24?this.y=24:this.y; this.Wing++; this.Wing>2?this.Wing=0:null; } //落地检测 if(this.y>game.canvas.height-114-10){ game.Sm.enter(3); } }; Bird.prototype.render=function(){ game.draw.save(); game.draw.translate(this.x,this.y); game.draw.rotate(this.changeRad); game.draw.drawImage(this.img[this.Wing],-24,-24); game.draw.restore(); }; Bird.prototype.fly=function(){ //点击canvas上升一点距离 this.status="moveUp"; this.changeRad=-1.2; this.changeY=10; } })();
