注册碰撞回调函数，destroy销毁节点报错，延时无效仍报错

Creator 3.x
#1

  • Creator 版本： 3.8.1

  • 目标平台：Chrome

  • 重现方式：
    start() {

      let collider = this.getComponent(BoxCollider2D);

  if(collider){

      collider.on(Contact2DType.PRE_SOLVE,this.onPreSolve,this);

  }

    }

    onPreSolve(selfCollider: Collider2D, otherCollider: Collider2D, contact: IPhysics2DContact | null){

      if(otherCollider.tag == 2){

      this.scheduleOnce(()=>{

          otherCollider.node.destroy();

      },1);          

  }

    }

  • 首个报错：Cannot read properties of null (reading ‘destroy’)/nTypeError: Cannot read properties of null (reading ‘destroy’)

#2

延迟一帧试试

#3

写了延迟函数

#4

感谢反馈，能整个复现demo吗？谢谢

#5

写个判断 if (otherCollider && otherCollider.node) {
otherCollider.node.destroy();
} else {
console.warn(“otherCollider or otherCollider.node is null”);
}
