『功能项目』宠物的召唤跟随【79】

server/2024/10/19 23:28:22/

我们打开上一篇78装备齐全特效的项目，

本章要做的事情是实现宠物跟随功能

首先创建一个宠物召唤界面

重命名按钮组件为CallPetBtn

重命名Image组件为PetExample

宠物资源所在资源文件夹

在主角预制体中的身后位置设置一个宠物跟随点

创建宠物动画控制器

拖拽至Pet01预制体动画控制器框选

创建脚本：PetFollowTarget.cs

实现宠物到达目标点就播放Idle动画，未到目标点就朝着目标点前进

using UnityEngine;
public class PetFollowTarget : MonoBehaviour{Transform target; float speed = 2f; Animator animator;void Start(){target = GameObject.Find("PlayerNormal/PetsSmallPos").gameObject.transform;animator = GetComponent<Animator>(); }void Update(){if (target != null){Vector3 direction = target.position - transform.position;float distance = direction.magnitude;if (distance > 0.1f){animator.SetBool("IsMoving", true);transform.LookAt(target.position);transform.position = Vector3.MoveTowards(transform.position, target.position, speed * Time.deltaTime);}else{animator.SetBool("IsMoving", false);}}}
}

修改脚本：CallOrHidePet.cs

using UnityEngine;
using UnityEngine.UI;
public class CallOrHidePet : MonoBehaviour{Button callBtn;GameObject petPrefab;GameObject petInstance;void Start(){petPrefab = Resources.Load<GameObject>("Prefabs/Pets/Pet01Small");callBtn = transform.Find("Image/CallPetBtn").GetComponent<Button>(); ;callBtn.onClick.AddListener(OnCallButtonClick);}public void OnCallButtonClick(){if (petInstance == null){petInstance = Instantiate(petPrefab,GameObject.FindWithTag("Player").transform.position + new Vector3(-2f, 0, -1f),Quaternion.identity);petInstance.AddComponent<PetFollowTarget>();}else{if (GameObject.Find("PlayerNormal") == null)return;elseDestroy(petInstance);}}void OnDestroy(){Button callBtn = transform.Find("Image/CallPetBtn").GetComponent<Button>();if (callBtn != null)callBtn.onClick.RemoveListener(OnCallButtonClick);}
}

修改脚本：UIManager.cs

实现开关宠物界面及召唤关闭宠物
