自定义两个类 ANode Actor 设置Actor 继承ANode ANode没有父类
@ccclass(‘ANode’)
export class ANode {
public node: Node = null!;
constructor(…params: any) {
this.node = new Node();
}
}
@ccclass(‘Actor’)
export class Actor extends ANode {
constructor(…params: any) {
super(params);
}
}
发布为 web-mobile
var ccclass = _decorator.ccclass;
var Actor = exports(‘Actor’, (_dec = ccclass(‘Actor’), _dec(_class = (_temp = /#PURE/function (_ANode) {
:10095 _inheritsLoose(Actor, _ANode);
function Actor() {
var _this;
执行些函数时 superClass 为undefined
function _inheritsLoose(subClass, superClass) {
：52 subClass.prototype = Object.create(superClass.prototype);
subClass.prototype.constructor = subClass;
_setPrototypeOf(subClass, superClass);
}
求原因，因很多类对ANode进行继承 问题都同上 一直查不出原因来
执行_inheritsLoose函数 superClass为空，然后不报错了
TypeError: Cannot read property ‘prototype’ of undefined
