Vector4.operator - 运算符 减法

static operator - (a : Vector4, b : Vector4) : Vector4

Description描述

Subtracts one vector from another.

一个向量减去另一个向量

Subtracts each component of b from a.

从a的对应的每个组件减去b对应的每个组件。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public void Awake() {
		print(new Vector4(1, 2, 3, 4) - new Vector4(6, 5, 4, 3));
	}
}
// prints (-5.0,-3.0,-1.0,1.0)
print (Vector4(1,2,3,4) - Vector4(6,5,4,3));

• static operator - (a : Vector4) : Vector4

Description描述

Negates a vector.

向量求反。

Each component in the result is negated.

结果是向量的每个组件取它相反数。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public void Awake() {
		print(-new Vector4(1, 2, 3, 4));
	}
}
// prints (-1.0,-2.0,-3.0,-4.0)
print (-Vector4(1,2,3,4));
