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() { // 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; } }
