[游戏开发]Unity入门：飞向目标

自动调整飞机的方向，飞向目标

（相对运动 方向问题）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Myjet : MonoBehaviour
{

    // Start is called before the first frame update
    void Start()
    {
        //Debug.Log("y轴向量：" + transform.up);
        //Debug.Log("x轴向量：" + transform.right);
        //Debug.Log("y轴向量："+transform.forward);

        Vector3 face = this.transform.up;

        GameObject target = GameObject.Find("飞机2");

        Vector3 direction = target.transform.position - this.transform.position;
        //得到方向向量

        //求旋转夹角
        float angle = Vector3.SignedAngle(face, direction, Vector3.forward);

        this.transform.Rotate(0, 0, angle);//旋转
    }



    // Update is called once per frame
    void Update()
    {
        float step = 1.2f * Time.deltaTime;
        //沿着机头指向的y方向移动
        transform.Translate(0, step, 0, Space.Self);
    }
