> Converts a Vector3 to a Vector4.

## Definition

* **Type:** Operator
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

## implicit operator Vector4(Vector)

Converts a [Vector3](/engine/6000.0/script-reference/unityengine/vector3.md) to a Vector4.

```csharp
public static implicit operator Vector4(Vector3 v)
```

### Parameters

**** (\[Vector3]\(/engine/6000.0/script-reference/unityengine/vector3)): The Vector3 to convert.

### Returns

| Type                                                              | Description |
| ----------------------------------------------------------------- | ----------- |
| [Vector4](/engine/6000.0/script-reference/unityengine/vector4.md) |             |

### Remarks

Vector3s can be implicitly converted to Vector4 (w is set to zero in the result).

### Examples

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

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        // color as a Vector3 (red, green, blue)
        Vector3 color = new Vector3(1.0f, 0.25f, 0f);

        // This converts the Vector3 to a Vector4 with the w parameter set to 0
        Vector4 colorWithOpacity = color;
        // set the opacity in the w parameter
        colorWithOpacity.w = 0.75f;
    }
}
```

## implicit operator Vector3(Vector)

Converts a Vector4 to a [Vector3](/engine/6000.0/script-reference/unityengine/vector3.md).

```csharp
public static implicit operator Vector3(Vector4 v)
```

### Parameters

**** (\[Vector4]\(/engine/6000.0/script-reference/unityengine/vector4)): The Vector4 to convert.

### Returns

| Type                                                              | Description |
| ----------------------------------------------------------------- | ----------- |
| [Vector3](/engine/6000.0/script-reference/unityengine/vector3.md) |             |

### Remarks

An implicit conversion of a [Vector4](/engine/6000.0/script-reference/unityengine/vector4.md) to a [Vector3](/engine/6000.0/script-reference/unityengine/vector3.md). The [Vector4.w](/engine/6000.0/script-reference/unityengine/vector4/w.md) is discarded.

### Examples

```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Create and display a Vector4.
        Vector4 vector4;

        vector4 = new Vector4(1.0f, 2.0f, 3.0f, 4.0f);
        Debug.Log("Vector4: " + vector4);

        // Convert the Vector4 into a Vector3.
        Vector3 vector3;
        vector3 = vector4;

        // The 4.0f is not copied into the Vector3.
        // Show (1.0f, 2.0f, 3.0f).
        Debug.Log("Vector3: " + vector3);
    }
}
```

## implicit operator Vector4(Vector)

Converts a [Vector2](/engine/6000.0/script-reference/unityengine/vector2.md) to a Vector4.

```csharp
public static implicit operator Vector4(Vector2 v)
```

### Parameters

**** (\[Vector2]\(/engine/6000.0/script-reference/unityengine/vector2)): The Vector2 to convert.

### Returns

| Type                                                              | Description |
| ----------------------------------------------------------------- | ----------- |
| [Vector4](/engine/6000.0/script-reference/unityengine/vector4.md) |             |

### Remarks

Vector2s can be implicitly converted to Vector4 (z and w are set to zero in the result).

### Examples

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


public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        Renderer renderer = GetComponent<Renderer>();

        // Shader vectors are always defined as Vector4.
        // The value here is converted to a Vector4 from a Vector2.
        renderer.material.SetVector("_SomeVariable", Vector2.one);
    }
}
```

## implicit operator Vector2(Vector)

Converts a [Vector4](/engine/6000.0/script-reference/unityengine/vector4.md) to a [Vector2](/engine/6000.0/script-reference/unityengine/vector2.md).

```csharp
public static implicit operator Vector2(Vector4 v)
```

### Parameters

**** (\[Vector4]\(/engine/6000.0/script-reference/unityengine/vector4)): The Vector4 to convert.

### Returns

| Type                                                              | Description |
| ----------------------------------------------------------------- | ----------- |
| [Vector2](/engine/6000.0/script-reference/unityengine/vector2.md) |             |

### Remarks

An implicit conversion of a [Vector4](/engine/6000.0/script-reference/unityengine/vector4.md) to a [Vector2](/engine/6000.0/script-reference/unityengine/vector2.md). [Vector4.z](/engine/6000.0/script-reference/unityengine/vector4/z.md) and [Vector4.w](/engine/6000.0/script-reference/unityengine/vector4/w.md) are discarded.

### Examples

```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Create and display a Vector4.
        Vector4 vector4;

        vector4 = new Vector4(1.0f, 2.0f, 3.0f, 4.0f);
        Debug.Log("Vector4: " + vector4);

        // Convert the Vector4 into a Vector2.
        Vector2 vector2;
        vector2 = vector4;

        // The values 3.0f and 4.0f are not copied into the Vector2.
        // Show (1.0f, 2.0f).
        Debug.Log("Vector2: " + vector2);
    }
}
