public static function Angle(from: Vector3, to: Vector3): float;
public static float Angle(Vector3 from, Vector3 to);
public static def Angle(from as Vector3, to as Vector3) as float

## Parameters

 from このベクトルから角度を計算します to このベクトルまでの角度を計算します

## Description

2点間（ `from``to` ）の角度を返します

```	// prints "close" if the z-axis of this transform looks
// almost towards the target

var target : Transform;
function Update () {
var targetDir = target.position - transform.position;
var forward = transform.forward;
var angle = Vector3.Angle(targetDir, forward);
if (angle < 5.0)
print("close");
}
```
```using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
public Transform target;
void Update() {
Vector3 targetDir = target.position - transform.position;
Vector3 forward = transform.forward;
float angle = Vector3.Angle(targetDir, forward);
if (angle < 5.0F)
print("close");

}
}
```
```import UnityEngine

public target as Transform

def Update() as void:
targetDir as Vector3 = (target.position - transform.position)
forward as Vector3 = transform.forward
angle as float = Vector3.Angle(targetDir, forward)
if angle < 5.0F:
