【sunny land】利用Animation编辑器实现近战敌人判定

昨晚研究了一晚Boss近战判定，也找了一些方法，但始终找不到合适的

今天终于让我找到了[泪目]

让我们先看演示

这个效果是我们的Boss挥刀时不造成伤害，当火焰冒出来时再对主角造成伤害。

这个我讲详细点吧

步骤：

首先，我们创建两个空对象

左伤害和右伤害，当主角在攻击范围内时进行攻击，

然后我们挂载伤害脚本和点碰撞体

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

public class MeleeAttack : MonoBehaviour
{
    // Start is called before the first frame update
    public float hurt;
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }
    private void OnTriggerEnter2D(Collider2D other)
    {
        foxcontroller fox = other.gameObject.GetComponent<foxcontroller>();
        Rigidbody2D rb = other.gameObject.GetComponent<Rigidbody2D>();
        if (fox != null){
            Vector2 Force = new Vector2(transform.position.x - rb.position.x, 0);
            fox.ChangeHealth(-2);//近战攻击扣两滴血，要是难度太高再削
            rb.AddForce(-Force * hurt);//这里是击退效果，其实可以不加负号，我前面写反了这里图方便加了个负号
        }
    }
}

对主角造成伤害并击退

然后是动画控制

目前是三个，但是我还在做，后面还有其他的状态

    public GameObject LeftAttack;
    public GameObject RightAttack;

    public float MeleeAttackRadial;

    private bool Attacking;
    public  bool canAttack = true;
    public float canAttackingTime = 4f;
    public float Timerr;
    void Start()
    {
        Timer = changeTime;
        animator = GetComponent<Animator>();
        Timerr = canAttackingTime;
    }

    // Update is called once per frame
    void Update()
    {
        Attack();
        runNormal();
        if (Timerr > 0)
        {
            Timerr -= Time.deltaTime;
            canAttack = false;
        }
        else canAttack = true;
    }

private void Attack()
    {
        if (fox.transform.position.x - transform.position.x > 9 || fox.transform.position.x - transform.position.x < -9)
        {
            LeftAttack.SetActive(false);
            RightAttack.SetActive(false);
        }
        if (!canAttack)
        {
            Attacking = false;
            animator.SetBool("Attacking", false);
            return;
        }
        if (fox.transform.position.x - transform.position.x < 9 && fox.transform.position.x - transform.position.x > 0&&direction == 1)
        {
            Timerr = canAttackingTime;
            Attacking = true;
            //RightAttack.SetActive(true);
            animator.SetFloat("look", fox.transform.position.x - transform.position.x);
            animator.SetBool("Attacking", true);
        }
        else if (fox.transform.position.x - transform.position.x > -9 && fox.transform.position.x - transform.position.x < 0&&direction == -1)
        {
            Timerr = canAttackingTime;
            Attacking = true;
            //LeftAttack.SetActive(true);
            animator.SetFloat("look", fox.transform.position.x - transform.position.x);
            animator.SetBool("Attacking", true);
        }
        else
        {
            Attacking = false;
            LeftAttack.SetActive(false);
            RightAttack.SetActive(false);
            animator.SetBool("Attacking", false);
        }
    }

攻击代码，当Boss攻击冷却好并且主角处于攻击范围内并面朝主角时，开始攻击主角，脚本里我只播放攻击动画，判定我在Animation工具里解决

这里我点击Add Property，添加事件，在播放动画时，在冒火的帧上将前面我们设置的空对象设置成true，也就是leftAttack.SetActive(true);

这样我们就能够在特定的帧上面对主角进行伤害了，Boss控制脚本我们就播放动画，伤害在Animation里解决
