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"); } }
