  • C#

  • JavaScript

using UnityEngine;using System.Collections;public class example : MonoBehaviour {public void Awake() {print(new Vector2(1, 2) - new Vector2(3, 2));}}
// prints (-2.0,0.0)print (Vector2(1,2) - Vector2(3,2));

static operator - (a : Vector2) : Vector2

Description描述

Negates a vector.

向量求反

Each component in the result is negated.

结果是每个组件是取它相反数。

  • C#

  • JavaScript

using UnityEngine;using System.Collections;public class example : MonoBehaviour {public void Awake() {print(-new Vector2(1, 2));}}
// prints (-1.0,-2.0)print (-Vector2(1,2));
