Description 描述

Converts a Vector4 to a Vector2.
四维向量转换为二维向量。

Vector4s can be implicitly converted to Vector2 (z and w is discarded).
四维向量能被隐式转换为二维向量(z和w将会被忽略)。

JavaScript:

#pragma strict
function Start() {
	// But the value here is converted to a Vector2.
	var value: Vector2 = Vector2.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 Vector2.
        Vector2 value = Vector2.one;
        Renderer renderer = GetComponent<Renderer>();
        renderer.material.SetVector("_SomeVariable", value);
    }
}
