// Convert a white color to a vector4 var aVector4 : Vector4 = Color.white;
using UnityEngine; using System.Collections; public class ExampleClass : MonoBehaviour { public Vector4 aVector4 = Color.white; }
import UnityEngine import System.Collections public class ExampleClass(MonoBehaviour): public aVector4 as Vector4 = Color.white
