08 动画控制器

首先在动画系统内添加 blend tree 设置好动画

随后在代码内控制速度对应的动画播放

注：注释的代码是不相关的代码，是前面的

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

public class PlayerController : MonoBehaviour
{
    //private NavMeshAgent agent;
    private Animator anim;
    //首先获取 animator

    private void Awake()
    {
        //agent = GetComponent<NavMeshAgent>();
        anim = GetComponent<Animator>();
    }

    //private void Start()
    //{
        //MouseManager.Instance.OnMouseClicked += MoveToTarget;
        //这是一个事件
    //}


   private void Update()
    {
        SwitchAnimation();
    }

    void SwitchAnimation()
    {
        anim.SetFloat("Speed", agent.velocity.sqrMagnitude);
        //将agent的速度传给动画
    }
    //void MoveToTarget(Vector3 target)
    //{
        //agent.destination = target;
    //}

}

遮挡

---

取消树的射线 改变树的图层为 🐉忽略射线🐉

第二种方法：由于代码中的碰撞是collider，只需要取消物体的mesh collider 即可

10 设置敌人

将史莱姆和蜗牛的材质都升级到urp材质

创建个脚本叫 enemy controller.cs

[RequireComponent(typeof(NavMeshAgent))]
//将脚本拖拽到物体上 会自动创建一个NavMeshAgent

敌人的遮挡剔除

设置一个图层为enemy

回到pipline settings找到render 在layer mask中 选中enemy（那个是可以多选的），同样infront内layer mask 也要选上

修改鼠标指针贴图

//回到MouseManager.cs
void SetCursorTexture()
    {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        //鼠标的位置与相机的催化剂
        if (Physics.Raycast(ray, out hitInfo))
        {
            //切换鼠标贴图
            switch (hitInfo.collider.gameObject.tag)
            {
                case "Ground":
                    Cursor.SetCursor(target,new Vector2(16,16),CursorMode.Auto);
                    //纹理，锚点，切换模式
                    break;
                    -----------------------
                case "Enemy":
                    Cursor.SetCursor(attack,new Vector2(16,16),CursorMode.Auto);
                    //当鼠标指针掠过敌人，指针会变成🗡
                    break;
                    -----------------------
            }
        }
    }

协程

//订阅事件

public class PlayerController : MonoBehaviour
{
    private NavMeshAgent agent;
    private Animator anim;

    private float lastAttackTime;

    //攻击冷却时间
    private void Awake()

        lastAttackTime -= Time.deltaTime;
    }

    void SwitchAnimation()

//延迟

        //转向这个攻击目标
        transform.LookAt(attackTarget.transform);

            agent.destination = attackTarget.transform.position;
            yield return null;

            lastAttackTime = 0.5f;
        }
    }

//获取GameObject的坐标

// [System.Serializable]
// public class EventVector3 : UnityEvent<Vector3>


public class MouseManager : MonoBehaviour

            {

            }
            ------------------------
            if (hitInfo.collider.gameObject.CompareTag("Enemy"))
            {
                    OnEnemyClicked?.Invoke((hitInfo.collider.gameObject));
            }
            ------------------------
        }
    }
}

//打断攻击动画

在移动方法内添加终止协程

void MoveToTarget(Vector3 target)
  {
      //打断攻击动画
      StopAllCoroutines();
      //⭐核心⭐
      agent.destination = target;
      agent.isStopped = false;

  }
