RPG项目01_技能释放

基于“RPG项目01_新输入输出”，

修改脚本文件夹中的SkillBase脚本：

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

//回复技能，魔法技能，物理技能
public enum SkillType { Up, Magic, Physics };
public class SkillBase : MonoBehaviour{
    protected GameObject prefab;
    protected SkillType type;//类型
    protected string path = "Skill/";
    protected string skillName;
    protected int attValue;
    public int mp;
    protected People from;//从人物释放
    protected People tPeople;//敌人目标
    protected Dictionary<SkillType, UnityAction> typeWithSkill =
        new Dictionary<SkillType, UnityAction>();
    protected float time = 0;//计时器
    protected float skillTime;//技能冷却时间
    protected float delayTime;//延迟时间
    protected float offset;//偏移量
    protected Vector3 skillPoint;//攻击点
    public bool IsRelease { get; private set; }//技能是否释放
    protected int layer;//技能对哪个一层起作用
    protected Collider[] cs;//技能碰撞体
    public event UnityAction Handle;//处理方法
    protected void Init(){
        IsRelease = true;
        layer = LayerMask.GetMask("MyPlayer") + LayerMask.GetMask("Enemy");
        prefab = LoadManager.LoadGameObject(path + skillName);
        typeWithSkill.Add(SkillType.Magic, MagicHurt);
        typeWithSkill.Add(SkillType.Physics, PhysicsHurt);
        typeWithSkill.Add(SkillType.Up, HpUp);
    }
    #region 技能
    private void MagicHurt(){
        cs = GetColliders();
        foreach (Collider c in cs){
            if (c.tag != from.tag){
                c.GetComponent<People>().BeMagicHit(attValue, from);
                c.GetComponent<People>().Anim.SetTrigger("Hurt");
            }
        }
    }
    private void PhysicsHurt(){
        cs = GetColliders();
        foreach (Collider c in cs){
            if (c.tag != from.tag){
                c.GetComponent<People>().BePhysicsHit(attValue, from);
                c.GetComponent<People>().Anim.SetTrigger("Hurt");
            }
        }
    }
    private void HpUp(){
        cs = GetColliders();
        foreach (Collider c in cs){
            if (c.tag == from.tag){
                c.GetComponent<People>().AddHp(attValue);
            }
        }
    }
    #endregion
    protected virtual Collider[] GetColliders(){
        return null;
    }
    public float GetFillTime(){
        if (IsRelease){
            return 0;
        }
        time -= Time.deltaTime;
        if (time < 0){
            IsRelease = true;
        }
        return time / skillTime;
    }
    public void SetEventHandle(UnityAction fun){
        Handle += fun;
    }
    public bool MayRelease(){
        return (from.Mp + mp >= 0) && IsRelease;
    }
    //携程函数-技能释放执行
    public virtual IEnumerator SkillPrefab(){
        IsRelease = false;
        time = skillTime;
        yield return new WaitForSeconds(delayTime);//等待延迟时间
        typeWithSkill[type]();
        from.AddMp(mp);
        skillPoint = from.transform.position + from.transform.forward * offset;
        Quaternion qua = from.transform.rotation;//施放角度
        GameObject effect = Instantiate(prefab, skillPoint, qua);
        yield return new WaitForSeconds(3);//等待三秒
        Handle?.Invoke();//时间调用
        Destroy(effect);//特效销毁
    }
}
技能基类创建完后创建技能子类StraightSkill

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class StraightSkill : SkillBase
{//直线技能
    float length;
    float width;
    public StraightSkill(People p, string _name, SkillType _type,
        float _length, float _width, int _att, int _mp, float _skillTime, float _delayTime, float _offset){
        from = p;
        length = _length;
        width = _width;
        skillName = _name;
        mp = _mp;
        type = _type;
        attValue = _att;
        skillTime = _skillTime;
        delayTime = _delayTime;
        offset = _offset;
        Init();
    }
    protected override Collider[] GetColliders(){
        skillPoint = from.transform.position + from.transform.forward * offset;
        Vector3 bound = new Vector3(width * width, length);
        return Physics.OverlapBox(skillPoint, bound, Quaternion.LookRotation(from.transform.forward), layer);
    }
}
再创建球型子类：

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

public class SphereSkill : SkillBase
{//球型技能
    float r;
    public SphereSkill(People p, string _name, SkillType _type, float _r,
        int _att, int _mp, float _skillTime, float _delayTime, float _offset){
        from = p;
        r = _r;
        skillName = _name;
        mp = _mp;
        type = _type;
        attValue = _att;
        skillTime = _skillTime;
        delayTime = _delayTime;
        offset = _offset;
        Init();
    }
    protected override Collider[] GetColliders(){
        skillPoint = from.transform.position + from.transform.forward * offset;
        return Physics.OverlapSphere(skillPoint, r, layer);
    }
}

接下来在角色类中修改代码添加技能：

修改MyPlayer代码：

将技能预制体包导入：

运行即可释放技能：

按E拔刀后按F1/F2/F3/F4/F5/F6键释放技能

同一个技能不能连续释放是因为冷却，

如果不同技能释放一个后另一个释放不了是因为mp不够，

设置mp初始及mp最大容量

即可释放完F1技能后还可以释放F2/F3/F4/F5/F6技能：
