Vector3.Angle 角度

static function Angle (from : Vector3, to : Vector3) : float

Description描述

Returns the angle in degrees between from and to.

由from和to两者返回一个角度。形象的说,from和to的连线和它们一个指定轴向的夹角。

using UnityEngine;
using System.Collections;

public class example : 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");

	}
}
// prints "close" if the z-axis of this transform looks
// almost towards the target
//如果当前变换z轴接近目标小于5度的时候,打印"close"
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");
}
