鱼图片左右移动时,设置鱼头朝向鼠标滑动的方向

img


//创建app
var app = new PIXI.Application(800,600);
document.body.appendChild(app.view);

//添加背景
var bg = new PIXI.Sprite.fromImage("res/lianxi/yu2/bg.png");
app.stage.addChild(bg);

//添加小鱼
var fish = new PIXI.Sprite.fromImage("res/lianxi/fish/fish.png");
fish.anchor.set(0.5,0.5);
fish.scale.x = 2;
fish.scale.y = 2;
fish.x = 100;
fish.y = 200;
app.stage.addChild(fish);

//给小鱼添加鼠标事件
bg.interactive = true;
bg.on("mousemove",movefish);


function movefish(event) {
    var pos = event.data.getLocalPosition(app.stage);
    fish.x = pos.x;
    fish.y = pos.y;
}

把你的代码用代码段</>的文本形式重新发一下，
