Extending existing class with getter

Unity Engine
1

Hi,

I’m missing some functionality in the Vector2 class, for example the normalized getter as in:

Vector2.normalized

How could I extend the existing class Vector2 with a getter? Is it possible in JS?

Any help greatly appreciated -

Vector2 is not a class but a struct.

As for extending it, you could write a static function in your class that will take a Vector2 in parameter and return the normalized vector… ?

By the way, if you want a getter/setter there is way.

I don’t know how to do it in JS but here is how it works in C#

using UnityEngine;
using System.Collections;

public class Test : MonoBehaviour {

	private string m_test;

	void Start () {
		m_test = "";
	}
	
	// Update is called once per frame
	void Update () {
	
	}
	
	public string MyTest
	{
		get { return m_test; }
		set { m_test = value; }
	}
}

Now you can use:

Test t = new Test();
t.MyTest = "Hello, World!";
Debug.Log(t.MyTest);

Hope it helps.

Scrat, many thanks for your replies.

Seems it’s not possible to use getters/setters in JS …

I’ll try your code in C#
