Vector4.Vector4

Description

Converts a Vector3 to a Vector4.

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

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        // Shader vectors are always Vector4s.
        // The value here is converted to a Vector4 from a Vector3.
        Renderer renderer = GetComponent<Renderer>();
        Vector3 value = renderer.material.GetVector("_SomeVariable");
    }
}
