Hi, I have created the main_menu scene which can lead to game_scene and about_scene. That was easy, the thing is when I wanted to load the main_menu scene by clicking the back button from about_scene, it didn’t work. I have a script to manage all the buttons like this
import { _decorator, Component, director, find, Input, Node } from 'cc';
const { ccclass, property } = _decorator;
@ccclass('ButtonManager')
export class ButtonManager extends Component {
@property(Node) public startBtn: Node | null = null;
@property(Node) public aboutBtn: Node | null = null;
@property(Node) public backBtn: Node | null = null;
protected onLoad(): void {
this.startBtn = find("Canvas/Text Holder/Start Button") as Node;
this.aboutBtn = find("Canvas/Text Holder/About Button") as Node;
this.backBtn = find("Canvas/Button/Back Button") as Node;
this.startBtn.on(Input.EventType.TOUCH_START, this.startDown, this);
this.aboutBtn.on(Input.EventType.TOUCH_START, this.aboutDown, this);
this.backBtn.on(Input.EventType.TOUCH_START, this.backDown, this);
}
//#region BUTTON PRESSED
startDown(): void {
// this.loadGameScene();
console.log("hehehehe");
}
aboutDown(): void {
this.loadAboutScene();
}
backDown(): void {
this.backToMainGame();
}
//#endregion
//#region SCENE LOADING
loadGameScene(): void {
director.loadScene("main_game");
}
loadAboutScene(): void {
director.loadScene("about_game");
}
backToMainMenu(): void {
director.loadScene("main_menu");
}
//#endregion
}
I want to attach the corresponding node from the current scene right in the script. And I got “[Preview] Cannot read property ‘on’ of null”. How can I fix this?
