Description

Vector3 转换为 Vector4。

Vector3 可以隐式转换为 Vector4(w 在结果中设置为零)。

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"); } }
