> Constructs a new vector with given x, y components.

## Definition

* **Type:** Constructor
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public Vector2(float x, float y)
```

### Parameters

**** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): The x component.**** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): The y component.

### Remarks

```csharp
//This script moves a GameObject to a new x position using a Vector2.
//Attach this script to a GameObject
//Set your x position in the Inspector

using UnityEngine;

public class Examples : MonoBehaviour
{
    Vector2 m_NewPosition;
    //This is the new X position. Set it in the Inspector.
    public float m_XPosition;

    // Use this for initialization
    void Start()
    {
        //Initialise the vector
        m_NewPosition = new Vector2(0.0f, 0.0f);
    }

    void Update()
    {
        //Press the space key to change the x component of the vector
        if (Input.GetKeyDown(KeyCode.Space))
        {
            m_NewPosition.x = m_XPosition;
        }
        //Change the position depending on the vector
        transform.position = m_NewPosition;
    }
}
```

```csharp
//This script shows how a GameObject can be moved to new positions using vectors.

//Attach this script to a GameObject. Click on the GameObject and the Inspector window appears. Change the “Second Vector” in the Inspector
//Attach a GameObject in the MyTransform field
//Also create 3 UI Buttons (<b>Create</b>><b>UI</b>><b>Button</b>) and go to each of their Inspectors to change their OnClick method (click the <b>+</b> button)
//Put your GameObject in each field. Use the <b>No function</b> dropdown to assign one Button with the  ZeroButton method, one with PositiveButton method and the other with the GameObjectButton method.


using UnityEngine;

public class Example : MonoBehaviour
{
    //Use these to set the GameObject's position
    Vector2 m_MyFirstVector;
    //Set this Vector in the Inspector (the position you would like the GameObject to move to)
    public Vector2 m_MySecondVector;
    Vector2 m_MyThirdVector;

    //You must assign to this Transform in the Inspector (could be another GameObject)
    public Transform m_MyTransform;

    void Start()
    {
        //Set the first vector to be at (0, 0, 0)
        m_MyFirstVector = Vector2.zero;
        //Set the third vector to the GameObject you set in the Inspector's position
        m_MyThirdVector = m_MyTransform.position;
    }

    public void ZeroButton()
    {
        //Press this Button to move your GameObject to the first vector position (0, 0)
        //Use this to move your GameObject to the origin (be wary of parent GameObjects)
        transform.position = m_MyFirstVector;
    }

    //Press this Button to move your GameObject to the second vector position (100, 200)
    public void PositionButton()
    {
        //Use this to move your GameObject to a specified position
        transform.position = m_MySecondVector;
    }

    //Press this Button to move your GameObject to the third vector position (The m_MyTransform's position)
    public void GameObjectButton()
    {
        //Use this to move your GameObject to another GameObject's position
        transform.position = m_MyThirdVector;
    }
}
```

A script that converts degrees into radians.  The radians are used to rotate around the origin.

```csharp
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ExampleScene : MonoBehaviour
{
    void Start()
    {
        float degrees = 45.0f;
        float radians = degrees * Mathf.Deg2Rad;

        Vector2 vec2 = new Vector2(Mathf.Cos(radians), Mathf.Sin(radians));
        Debug.Log(vec2);
    }
}
```
