在 C# 统一中使用多态性或接口

Question

在我的Unity C#游戏中，我有两个类，一个是PlayerHealth，另一个是EnemyHealth，它们具有相同的功能，但这两个字段是倒置的currentHapinessPower和currentSadnesPower。 不知道该用多态原理还是继承还是接口。

这些是类：

public class PlayerHealth : MonoBehaviour
{
    #region Public Instances
    public GameObject Player;
    public GameObject Pl_DeathParticle;

    public TextMeshProUGUI NumOfHappyPower;
    public TextMeshProUGUI NumOfSadPower;
    #endregion

    #region HapAndSad System Variables
    public int playerHappinessPower;
    [HideInInspector] public int currentHappinessPower; <--
    [HideInInspector] public int currentSadnesPower;    <--These two
    #endregion

    #region HapAndSad States
    private bool isSad = false;
    #endregion

    void Start()
    {
        currentHappinessPower = playerHappinessPower; // in the enemy class is currentSadnessPower
        NumOfSadPower.enabled = false; // here in the enemy class is true
    }

    void Update()
    {
        HapAndSadPowerSystem();
        StartCoroutine(CheckThePlayerSadState());
    }

    void HapAndSadPowerSystem()
    {
        if (currentHappinessPower > 0) //enemy class: currentSadnessPower
        {
            NumOfHappyPower.text = currentHappinessPower.ToString(); //also here is changed
        }

        else if (currentHappinessPower == 0) // here also is currentSadnessPower
        {
            NumOfHappyPower.enabled = false;
            NumOfSadPower.enabled = true;

        }

        else if (currentHappinessPower < 0 && currentSadnesPower == 0) //and here
        {
            isSad = true;  // enemy class is false                                                                  
            currentSadnesPower = currentHappinessPower * -1; //Make the rest of the soubstraction positive / also here its inverted
            NumOfHappyPower.enabled = false; //true in the enemy class
            NumOfSadPower.enabled = true; // false
            NumOfSadPower.text = currentSadnesPower.ToString();
        }

        else if (currentSadnesPower > 0)
        {
            NumOfSadPower.text = currentSadnesPower.ToString();
        }
    }

    IEnumerator CheckThePlayerSadState()
    {
        if (isSad == true) //here is false
        {
            yield return new WaitForSeconds(2f);
            GameObject PlayerDeath_particle_prefab = Instantiate(Pl_DeathParticle, Player.transform.position, Quaternion.identity);

            Destroy(PlayerDeath_particle_prefab.gameObject, 1f);
            Destroy(Player.gameObject);
        }
    }
}

这里是敌人类：

public class EnemyHealth : MonoBehaviour

    #region Public Instances
    public GameObject Enemy;
    public GameObject En_DeathParticle;

    public TextMeshProUGUI NumOfHappyPower;
    public TextMeshProUGUI NumOfSadPower;
    #endregion

    #region HapAndSad System Variables
    public int enemySadnesPower;
    [HideInInspector] public int currentHappinessPower;
    [HideInInspector] public int currentSadnesPower;
    #endregion

    #region HapAndSad States
    private bool isSad = true;
    #endregion

    void Start()
    {
        currentSadnesPower = enemySadnesPower;
        NumOfHappyPower.enabled = false;
    }

    void Update()
    {
        HapAndSadPowerSystem();
        StartCoroutine(CheckThePlayerSadState());
    }

    void HapAndSadPowerSystem()
    {
        if (currentSadnesPower > 0)
        {
            NumOfSadPower.text = currentSadnesPower.ToString();
        }

        else if (currentSadnesPower == 0)
        {
            NumOfHappyPower.enabled = true;
            NumOfSadPower.enabled = false;

        }

        else if (currentSadnesPower < 0 && currentHappinessPower == 0)
        {
            isSad = false;
            currentHappinessPower = currentSadnesPower * -1;
            NumOfHappyPower.enabled = true;
            NumOfSadPower.enabled = false;
            NumOfHappyPower.text = currentHappinessPower.ToString();
        }

        else if (currentHappinessPower > 0)
        {
            NumOfHappyPower.text = currentHappinessPower.ToString();
        }
    }

    IEnumerator CheckThePlayerSadState()
    {
        if (isSad == false)
        {
            yield return new WaitForSeconds(2f);
            GameObject PlayerDeath_particle_prefab = Instantiate(En_DeathParticle, Enemy.transform.position, Quaternion.identity);

            Destroy(PlayerDeath_particle_prefab.gameObject, 1f);
            Destroy(Enemy.gameObject);
        }
    }
}

Answer 1

这些脚本几乎相同。我会使用与玩家和敌人相同的脚本。并添加一个布尔值来区分玩家和敌人。

编辑： 如果你想拼命使用继承或多态，我建议你创建一个实体类，并让 Player 和 Enemy 派生自它。
