新手求助：新版本的碰撞体要怎么用？在回调中销毁节点会报错

Creator 3.x
#1

代码如下
onBeginContact (selfCollider: Collider2D, otherCollider: Collider2D, contact: IPhysics2DContact | null) {

    // 只在两个碰撞体开始接触时被调用一次

    this.node.destroy();

}

start () {

    // [3]

    let bulletCollider = this.getComponent(Collider2D);

    if (bulletCollider) {

        bulletCollider.on(Contact2DType.BEGIN_CONTACT, this.onBeginContact);

    }

}

错误信息
Uncaught TypeError: Cannot read properties of undefined (reading ‘node’)

这个我觉得是节点问题，尝试下判断this.node.isVaild 再执行销毁

#3

节点销毁最好放到帧末

#4

这时候碰撞逻辑其实还没执行完 ，延迟一帧执行就可以了

#5

如果你是用this.node的话可能需要把this bind进去。
