Persistent node

Cocos Creator
#1

Hello!

I want to make the object persistent. But I also need the object to be in different scenes.
How can you check whether an object exists? If exists, then destroy the current instance.

I’m using Cocos Creator version 3.8.1.

I meant that I needed a design similar to the one in Unity

void Awake() {
if (instance != null) {
Destroy(this.gameObject);
return;
} else {
instance = this;
}
DontDestroyOnLoad(this.gameObject);
}

#4 
    this.node.removeFromParent();
    director.addPersistRootNode(this.node);

If you want to destroy the node if it already exists just do it the same way you would in C# with Unity (like in your snippet). Static members are supported by Typescript, onLoad is the Cocos equivalent of Awake, so it’s all transferable.

This does not work.
