如题，想要获取播放回调，但是方法无效，大佬帮忙看看是写法写错了吗还是怎么回事？3种方式都没执行
com1(){
// console.log(">播放缓动结束>>>",Helloworld.getinstance(),Helloworld.getinstance().arr)
let no1=Helloworld.getinstance().arr[Helloworld.getinstance().index]
let n:sp.Skeleton=no1.getComponent("sp.Skeleton") as sp.Skeleton;
n.clearTracks();
n.setStartListener(this.starPlay);
let play1:sp.spine.TrackEntry=n.setAnimation(0,"attack1",false);
n.setTrackEndListener(play1,this.endPlay)
n.setCompleteListener(this.end2)
n.setEndListener(this.end3);
}
starPlay(){
console.log(">骨骼动画播放开始>>>",Helloworld.getinstance(),Helloworld.getinstance().arr)
}
endPlay(){
console.log(">骨骼动画播放结束>>>",Helloworld.getinstance(),Helloworld.getinstance().arr)
}
end2(){
console.log(">骨骼动画播放结束2222>>>",Helloworld.getinstance(),Helloworld.getinstance().arr)
}
end3(){
console.log(">骨骼动画播放结束3333>>>",Helloworld.getinstance(),Helloworld.getinstance().arr)
}
