説明

Vector4 を Vector3 に変換します

Vector4 は暗黙的に Vector3 に変換できます。( W 軸は無視されます)

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Start() { // Shader vectors are always Vector4s. // But the value here is converted to a Vector3. Vector3 value = Vector3.one; Renderer renderer = GetComponent<Renderer>(); renderer.material.SetVector("_SomeVariable", value); } }
