what is the equivalent of myObject = new GameObject(); in needle engine

Hello Saad Baig,

In Needle Engine, the equivalent of myObject = new GameObject(); from Unity can be accomplished by creating a new instance of an Object3D, as Needle Engine uses three.js under the hood.

Here’s how you can instantiate a new game object in Needle Engine:

import { Object3D } from "three";
import { GameObject } from "@needle-tools/engine";

// Create a new GameObject (also an Object3D)
const myObject = new GameObject();

In this code, myObject is created as a new instance of GameObject, which is a class that extends Object3D. You can then add components or manipulate this object as needed, similar to how you would in Unity.

If you need more help or specific functionalities, feel free to ask!

this already tried this solution gives error Cannot create an instance of an abstract class.

Hello Saad Baig,

In Needle Engine, GameObject is an abstract class, meaning you cannot directly instantiate it. Instead, you should create an instance using the instantiate() method, which is designed for this purpose. Here’s how you can do it:

  1. Define your prefab or object that you want to instantiate.
  2. Use the instantiate() method to generate a new instance of that object.

Here is a code snippet to guide you through this:

import { GameObject } from "@needle-tools/engine";

// Assuming you have a prefab reference, e.g., an AssetReference
const prefab: AssetReference;  // Replace with your prefab reference

async function createMyObject() {
    // Instantiate a new game object from the prefab
    const myObject = await prefab.instantiate();
    return myObject;
}

// Call the function to create the object
createMyObject().then(myObject => {
    // You can add components or manipulate myObject here as needed
});

This code assumes that you have an AssetReference to your prefab. The instantiate() function handles the creation of a new instance of that prefab.

Feel free to ask if you need further assistance!

Hello @saad_baig that would be new Object3D() (a GameObject is an Object3D and the type of “GameObject” doesnt really exist)
