游戏开发学习笔记（十五）怪物系统

//思路：

//判断距离，在设定距离内，走向主角
//在攻击距离内，攻击主角
//受到伤害处理

新建脚本Enemy，编辑脚本，在属性面板分别赋值敌人的属性（类型，血量，攻击，防御，速度等）

public enum EnemyType{    Boos,    Leader,    Monster,    UltimateBoss}public class Enemy : MonoBehaviour {    public static Enemy _instance;    public EnemyType enemyType = EnemyType.Monster;    public float hp = 100;    public float attack = 10;    public float def = 5;    public float speed = 3;    private Animator anim;    private CharacterController CC;    private GameObject player;    private float timer = 0;    //计时器，攻击计时    private float time = 2;    private bool ismoved = false;void Awake () {        _instance = this;    }    void Start()    {        player = TransformScripManage._instance.Player;        if (enemyType != EnemyType.UltimateBoss)        {            anim = this.GetComponent<Animator>();            CC = GetComponent<CharacterController>();        }    }    void Update()    {        if (player != null && PlayerState._instance.ReadremainHp() > 0)        {            ClosePlayer();        }    }    //走向主角    void ClosePlayer()    {        float distance = Vector3.Distance(transform.position, player.transform.position);   //判断距离        if (distance <= 10)        {            ismoved = true;            if (distance >= 2.5)    //判断是否在攻击距离内            {                if (enemyType != EnemyType.UltimateBoss)    //非终极Boss                {                    anim.SetInteger("Idle_Run", 3);                    if (anim.GetCurrentAnimatorStateInfo(1).IsName("Empty State"))  //当状态机处于“Empty State”时，及非攻击状态时。                    {                        transform.LookAt(player.transform);                        CC.SimpleMove(transform.forward * speed);                    }                }            }            else            {                anim.SetInteger("Idle_Run", 1);                Attack();            }        }        else        {            if (ismoved)            {                ismoved = false;                anim.SetInteger("Idle_Run", 1);            }        }    }    //攻击主角    void Attack()    {        if (player != null && PlayerState._instance.ReadremainHp() > 0) //当主角非死亡时        {            timer += Time.deltaTime;            if (timer > time)   //计时器            {                anim.SetTrigger("Attack");                if (hp > 0)                    PlayerState._instance.Hurt(attack);                transform.LookAt(player.transform);                timer = 0;            }        }    }    //受到伤害    void Hurt(float amountHurt)    {        if (hp > 0)        {            anim.SetTrigger("Damage");            amountHurt -= (Random.Range(1, 5) + def);            hp -= amountHurt;        }        if (hp <= 0)        {            anim.SetTrigger("Dead");            TransformScripManage._instance.Destory(this.gameObject);        }    }}
