While passing the level in my game, I am writing this code to delete everything in the level it passed, but why am I getting an error?

    //Bölümleri geçme
     if(result.other.tags.has("serigec") && this.count ==2 )
     {  
        setTimeout(() => {
        var oldHierarchy=this.app.root.findByName("Root");
        root.destroy();
        this.loadScene(this.sceneId,function(){});
        },1500);
  
    }

What error exactly are you receiving?

Check out this tutorial project on changing scenes:

https://playcanvas.com/project/437633/overview/changing-scenes

It should help you with the steps of destroying a scene and loading a new one.

If you would prefer a prebuilt scene manager, I have created one here that you are welcome to fork:

https://playcanvas.com/project/756176/overview/scene-manager

With it, you can fire the ‘changeScene’ event along with the name of the desired scene from anywhere in the app, and it will change the scene for you.

If you play my game, the objects from the previous scene remain at level 2

Without seeing the way the code and project are set up, it is difficult to provide specific support. With the information available, I can only guess that the objects that remain are not parented by the root element that you’re destroying.

Though taking a quick look, this doesn’t seem right:

root.destroy();

What exactly is root? It is not defined in that function.

this is my code

//Bölümleri geçme
     if(result.other.tags.has("serigec") && this.count ==2 )
     {  
        setTimeout(() => {
        var oldHierarchy=this.app.root.findByName("Root");
        oldHierarchy.destroy();
        this.loadScene(this.sceneId,function(){});
        },1500);
  
    }

    else if(result.other.tags.has("serigecdört") &&  this.count==4)
     {

What does this.loadScene do? I do not see the function listed in your code.

Again, I would recommend looking at the tutorial project to see what steps are taken when a scene is changed. Here is a direct link to the demonstration script:

You can also implement the Scene Manager I mentioned before very easily into your project:
