Is there any proper way of writing typescript as OOP like in C#

To convert TypeScript classes with decorators to Unity C# serializable classes, follow these steps:

  1. Define a C# class for the BoardArea equivalent with the Serializable attribute above the class declaration.
  2. Inside the class, declare all the properties that you want to serialize and ensure they are public or marked with the [SerializeField] attribute.
  3. For list properties, use List instead of arrays for Unity serialization support.
  4. In the MovementManager MonoBehaviour, declare a public List equivalent to hold instances of BoardArea.

Here’s an example in C# based on the description:

using System;
using System.Collections.Generic;
using UnityEngine;

// Define the serializable BoardArea class.
public class BoardArea {
    public Vector3 position; // Example of a serializable Vector3 property.

    public string name; // Example of a serializable string property.

    // Additional properties...

// Define the MovementManager MonoBehaviour with a List of BoardArea.
public class MovementManager : MonoBehaviour {
    public List<BoardArea> boardAreaList = new List<BoardArea>(); // Serialized list of BoardArea.

    // Additional logic...

By applying this example, you can adapt your TypeScript code for serialization in Unity by following the conventions of C# and Unity’s serialization system.

@Needle Engine Assistant and how do i get boardAreaList element value from typescript

by user 151660356224286721

To access the elements of the boardAreaList in TypeScript, you can use array indexing. Here’s an example of how to access the value of an element in boardAreaList:

// Assuming movementManagerInstance is an instance of MovementManager
// Access the first element in the boardAreaList
const firstBoardArea = movementManagerInstance.boardAreaList[0];

// Now you can access the properties of the first BoardArea
console.log(firstBoardArea.position);  // Example access of the position property
console.log(;  // Example access of the name property

Replace movementManagerInstance with the actual instance of MovementManager present in your code. This will allow you to access the elements and the properties of boardAreaList in TypeScript.

Replace movementManagerInstance with the actual instance of MovementManager present in your code. how do i do that?

by user 151660356224286721

Here is what I found for you :brain: Discord

To get the actual instance of MovementManager present in your code, you typically create an instance of MovementManager using the new keyword. If MovementManager is a singleton or attached to a game object, you would access it from the scene hierarchy or through a reference.

Here’s an example of how to get the instance of MovementManager if it’s attached to a GameObject in your scene:

// Get the scene instance of MovementManager by name
const movementManagerInstance = GameObject.findObjectOfType("MovementManager", MovementManager);
if (movementManagerInstance) {
    // Access the boardAreaList from the instance
    const firstBoardArea = movementManagerInstance.boardAreaList[0];
} else {
    console.error("MovementManager not found in the scene");

Replace "MovementManager" with the actual name of the GameObject in your scene. This code snippet assumes that MovementManager is attached to a GameObject in the scene, and it retrieves the instance using GameObject.findObjectOfType(). If MovementManager is not attached to any GameObject, you would need another way to obtain the instance, such as through a reference or a singleton pattern.

@Needle Engine Assistant I cannot find MovementManager because it is on the C# side, not the typescript side

by user 151660356224286721

I see, in that case, if the MovementManager instance is on the C# side, you will need to expose it to the TypeScript side through interop or some form of messaging system. One common approach is to use the Needle Engine’s networking capabilities to communicate between the TypeScript and C# sides.

You can create a custom event or message system in the C# code to send the boardAreaList or specific elements to the TypeScript side when needed. Then, in the TypeScript code, you can listen for these events or messages and handle the received data accordingly.

If you already have a networking or messaging system in place, you can use that to send the boardAreaList from the C# side to the TypeScript side for further processing.

If you have a specific messaging or networking system in place that you’d like to integrate with the Needle Engine, I can provide more detailed guidance based on the specific method you’re using.

@Needle Engine Assistant show me more specific examples in steps

Here is what I found for you :brain: Discord

To expose the boardAreaList from the C# side to the TypeScript side using Needle Engine’s built-in networking capabilities, you can follow these steps:

  1. Expose the Data: In your C# code, create a method or event to send the boardAreaList to be received on the TypeScript side. Use Needle Engine’s networking components such as SyncedRoom or SyncedTransform to synchronize the data.

  2. Subscribe in TypeScript: In your TypeScript code, subscribe to the event or method for receiving the boardAreaList data sent from the C# side.

  3. Handle the Data: When the boardAreaList data is received in the TypeScript side, handle it as needed for processing or display.

Here’s an example based on the steps above:

C# (Unity) Side:

public class MovementManager : MonoBehaviour
    // Expose the boardAreaList for synchronization using Needle Engine's SyncedRoom
    private List<BoardArea> boardAreaList;

    // ...

    // Method to send the boardAreaList data via networking
    private void SendBoardAreaListData()
        // Use Needle Engine's networking functionality to send the boardAreaList
        // Example sending the boardAreaList to a SyncedRoom

TypeScript (Needle Engine) Side:

// Subscribe to receive the boardAreaList data
SyncedRoom.Instance.onDataReceived((data: any) => {
    if (Array.isArray(data) && data.length > 0 && data[0] instanceof BoardArea) {
        const receivedBoardAreaList: BoardArea[] = data as BoardArea[];
        // Now you can handle the received boardAreaList as needed


In this example, the SyncedRoom is used as a communication channel for sending and receiving the boardAreaList data between C# and TypeScript. You may adapt this example according to your specific needs and the networking setup in your project.

@Needle Engine Assistant
on typeScript it is shown " ‘BoardArea’ is possibly ‘null’.

@Needle Engine Assistant
How do I access the class that are defined in c# and Instanciate in typescript before converting in to c# component?

by user 151660356224286721

Here is what I found for you :brain: Discord

In Needle Engine, when you need to instantiate a C# class and use it in TypeScript before converting it into a C# component, you can use the AssetReference type provided by Needle Engine to reference the C# script or prefab, and instantiate it in TypeScript.

Here is a step-by-step guide:

  1. Define an AssetReference in TypeScript to the C# class/prefab.
  2. Use the instantiate method provided by AssetReference to create an instance of the asset.
  3. Access the instantiated object’s properties and methods as needed.

Example TypeScript code:

import { AssetReference, Behaviour } from "@needle-tools/engine";

export class SomeComponent extends Behaviour {
    // Reference to the C# prefab or script asset
    private myCSharpScriptAsset: AssetReference;

    // Use this method to instantiate the C# asset
    async start() {
        if (this.myCSharpScriptAsset) {
            try {
                const instance = await this.myCSharpScriptAsset.instantiate();
                // The instance is now a GameObject that has the C# component attached
                // Access the properties or methods of the C# component as needed
                // For example, if the C# script has a method named 'Initialize'
            } catch (error) {
                console.error("Error instantiating the C# asset:", error);


In this example, replace "CSharpScriptName" with the actual class name of your C# component. The initialize function should correspond to a public method defined in your C# script. Also, make sure that "myCSharpScriptAsset" is assigned either programmatically or via the Needle Engine Editor where you link the C# prefab or script to the TypeScript AssetReference.

Please note that direct instantiation and usage of C# scripts in TypeScript won’t work without proper referencing and loading using AssetReference, as shown above. The details may vary depending on the specific setup and requirements of your project.

@Needle Engine Assistant I mean if instantiated classes are not from typescript then from unity it self
