Description 描述

Converts a Vector4 to a Vector3.
将四维向量转换为三维向量。

Vector4s can be implicitly converted to Vector3 (w is discarded).
四维向量能被隐式转化为Vector3（w被丢弃）。

JavaScript:

#pragma strict
function Start() {
	// But the value here is converted to a Vector3.
	var value: Vector3 = Vector3.one;
	var renderer: Renderer = GetComponent.<Renderer>();
	renderer.material.SetVector("_SomeVariable", value);
}

C#:

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);
    }
}
