怪物AI&数据模板

可视化

• OnDrawGizmos():画出所有
• OnDrawGizmosSelected()画出选中的

  void OnDrawGizmosSelected()
    {
        Gizmos.color = Color.blue;
        Gizmos.DrawWireSphere(transform.position, sightRadius);
    }

获得范围内随机点用于巡逻

void GetNewWayPoint()
    {
        //还原停留时间
        remainLookAtTime = lookAtTime;
        float randomX = Random.Range(-patrolRange, patrolRange);
        float randomZ = Random.Range(-patrolRange, patrolRange);
        Vector3 randomPoint = new Vector3(guardPos.x + randomX, transform.position.y, guardPos.z + randomZ);
        //随机点不能是障碍物
        NavMeshHit hit;
        //NavMesh.SamplePosition用于寻找与给定点距离最近的可用点
        //1指的是navmesh area里walkable的cost
        wayPoint = NavMesh.SamplePosition(randomPoint,out hit, patrolRange, 1) ? hit.position : transform.position;     
    }

ScriptableObject

-数值型文件,用于存储数据

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//默认文件名为New Data,菜单分级中为Character Stats/Data
[CreateAssetMenu(fileName ="New Data",menuName="Character Stats/Data" )]
//继承自ScriptableObject
public class CharacterData_SO : ScriptableObject
{
    [Header("Stats Info")]
    //最大血量
    public int maxHealth;
    //当前血量
    public int currentHealth;
    //基础防御
    public int baseDefence;
    //当前防御
    public int currentDefence;
}

• 数值文件实例
  

创建状态管理类用于管理数据

• get/set用于快速访问和修改

  sing System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  public class CharacterStats : MonoBehaviour
  {
    public CharacterData_SO characterData;
    public int MaxHealth
    {
        get{if (characterData != null)return characterData.maxHealth;else return 0;}
        set{characterData.maxHealth = value;}
    }
  }

同步脚本和动画的逻辑

void SwitchAnimation()
    {
        anim.SetBool("Walk", isWalk);
        anim.SetBool("Chase", isChase);
        anim.SetBool("Follow", isFollow);
        anim.SetBool("Critical", characterStats.isCritical);
        anim.SetBool("Death", isDead);

攻击造成伤害的实现

• 在Animation中添加帧事件

• 打开Animation面板
  

• 点击+号添加帧事件
  
  

• 触发Hit事件

  //Animation Event
    void Hit()
    {
        var targetStats = attackTarget.GetComponent<CharacterStats>();
        targetStats.TakeDamage(characterStats, targetStats);
    }

• 结算伤害

  //受到攻击
    public void TakeDamage(CharacterStats attacker,CharacterStats defender)
    {
        int damage = Mathf.Max(attacker.CurrentDamage() - defender.CurrentDefence,0);
        CurrentHealth = Mathf.Max(CurrentHealth - damage, 0);
        //暴击时触发挨打的人的受击动画
        if (attacker.isCritical)
        {
            defender.GetComponent<Animator>().SetTrigger("Hit");
        }
  
        //更新血量UI
  
        //结算经验值
  
    }

部分Animation无法添加帧事件的解决办法

• 包含在fbx文件中的动画是无法编辑的
  
• 使用ctrl+D将动画复制一份到fbx外,使用复制的动画即可编辑

Quaternion.Lerp

• 差值运算,用于缓慢执行某个动作
• 如缓慢从一个角度旋转到另一个角度

  transform.rotation = Quaternion.Lerp(transform.rotation,guardRotation,0.01f);

单位死亡时关闭相应组件

• 避免出现一遍播放死亡动画一遍移动,或是殴打尸体的情况

  collider.enabled = false;
  agent.enabled = false;

  泛型单例模式

• virtual为虚函数,在子类中使用override重载

  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  //泛型类
  public class Singleton<T> : MonoBehaviour where T:Singleton<T>
  {
    private static T instance;
    public static T Instance
    {
        get { return instance; }
    }
    protected virtual void Awake()//虚函数
    {
        if (instance != null)
            Destroy(gameObject);
        else
            instance = (T)this;
    }
    public static bool IsInitialized
    {
        get { return instance != null; }
    }
    protected virtual void OnDestroy()
    {
        if (instance == this)
        {
            instance = null;
        }
    }
  }
