Cc. Class ({
Extends: cc.Com ponent,

Properties: {
Testnode: cc) Node,
},

OnLoad () {
Let action=cc. MoveTo (3, 700, 326);
var self=this;
Cc. Loader. LoadRes (" star1 ", function (err, prefab) {
Self. Testnode. AddChild (cc. Instantiate (prefab), 1, "ttnode");
Self. Testnode. GetChildByName (" ttnode "). RunAction (action);
});
//this. Testnode. GetChildByName (" ttnode "). RunAction (action);
},
});

This could be the node of the prefab,

Cc. Class ({
Extends: cc.Com ponent,

Properties: {
Testnode: cc) Node,
},

OnLoad () {
Let action=cc. MoveTo (3, 700, 326);
var self=this;
Cc. Loader. LoadRes (" star1 ", function (err, prefab) {
Self. Testnode. AddChild (cc. Instantiate (prefab), 1, "ttnode");
//self. Testnode. GetChildByName (" ttnode "). RunAction (action);
});
This. Testnode. GetChildByName (" ttnode "). RunAction (action);
},
});

After changing it, in cc. Loader. Can't loadRes outside of the prefab node, quote: [ERROR] : the object already destroyed,
How in the cc. Loader. LoadRes outside to dynamically add node of prefab to operate?
