我也发现玩家的血减不了，但是EnemySpider的血是可以减的

GameObject.cs

void Start()

{

playerHealth = player.GetComponent<Health>();

healthText.text = playerHealth.health.ToString();//UI的healthText的内容

}

void OnDamage( Health health )

{

// playerHealth = player.GetComponent<Health>();

// healthText.text = playerHealth.health.ToString();

if (health == playerHealth)

healthText.text = health.health.ToString();//改变UI中的health,该Health应该为player的health

}

health.cs中

public void OnDamage( int damage = 1 )

{

health --;

damageSignals.SendSignals(this, this);//生命值减一，并发送信息

if (health == 0)

deathSignals.SendSignals (this, gameObject);

}

void OnEnable()

{

health = maxHealth;

}

贴一段减少血量的代码看看
