Vector2.operator - 运算符 减法
static operator - (a : Vector2, b : Vector2) : Vector2
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b对应的每个组件。
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。
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));
