将 Vector4 转换为 Vector3

Vector4 可以隐式转换为 Vector3(w 被丢弃)。

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); } }
