Question

因此，每当骷髅碰到玩家/角色时，它不会显示单词“ HIT！”。我做错了什么？

骨架敌人脚本

private Rigidbody2D myBody;

[Header("Movement")]
public float moveSpeed;
private float minX, maxX;
public float distance;
public int direction;

private bool patrol, detect;

private Transform playerPos;
private Animator anim;

[Header("Attack")]
public Transform attackPos;
public float attackRange;
public LayerMask playerLayer;
public int damage;

//sound

无效觉

void Awake()
{
    anim = GetComponent<Animator>();
    playerPos = GameObject.Find("George").transform;
    myBody = GetComponent<Rigidbody2D>();
}

无效启动

private void Start()
{
    maxX = transform.position.x + (distance);
    minX = maxX - distance;

    //if (Random.value > 0.5) direction = 1;
    //else direction = -1;
}

无效更新

            Vector3 playerDir = (playerPos.position - transform.position).normalized;

            if (playerDir.x > 0)
                myBody.velocity = new Vector2(moveSpeed + 0.4f, myBody.velocity.y);

无效攻击

 public void Attack()

        Collider2D attackPlayer = Physics2D.OverlapCircle(attackPos.position, attackRange, playerLayer);

        {
            if(attackPlayer.tag == "Player")
            {
                print("Hit!");
                attackPlayer.gameObject.GetComponent<PlayerHealth>().TakeDamage(damage);
            }
        }
    }
    private void OnDrawGizmosSelected()

        Gizmos.DrawWireSphere(attackPos.position, attackRange);
    }

玩家健康脚本

无效觉

 public int health = 100;

    void Awake()

    }

无效更新

禁止破坏

 public void TakeDamage(int damage)
    {
        FindObjectOfType<CameraShake>().ShakeItMedium();
        health -= damage;
    }

    private void OnTriggerEnter2D(Collider2D target)
    {
        if(target.tag == "Fireball")
        {
            TakeDamage(25);
        }
    }

Answer 1

尽管那堆长代码可能还有很多其他问题：

if (attackPlayer == null) { if(attackPlayer.tag == "Player") { print("Hit!"); attackPlayer.gameObject.GetComponent<PlayerHealth>().TakeDamage(damage); } }

您检查attackPlayer是否为空，然后尝试对其进行处理...我很确定您是说if (attackPlayer != null) ...

Answer 2

您似乎没有在脚本中调用“攻击”方法。

else if (Vector2.Distance(playerPos.position, transform.position) <= 1.0)
{
    myBody.velocity = new Vector2(0, myBody.velocity.y);
    // calling the attack method, so the physics cast is being made
    Attack();
    anim.SetBool("Attack", true);
}

别忘了更改此设置，您正在检查演员是否击中任何东西而不是击中东西。

// if the cast hit something
if (attackPlayer != null)
{
    if(attackPlayer.tag == "Player")
    {
        print("Hit!");
        attackPlayer.gameObject.GetComponent<PlayerHealth>().TakeDamage(damage);
    }
}

为什么我的骨架不会对我的玩家造成伤害？
