我一直在关注Unity提供的Shooter Survival教程。我一直在使用它来理解某些代码位如何与c＃中的不同脚本中的相互作用和相互调用。最近我遇到了一个问题，我没有从敌人的攻击中受到伤害;我仍然可以伤害他们。
我的玩家健康代码
using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using UnityEngine.SceneManagement;
namespace CompleteProject
{
public class PlayerHealth : MonoBehaviour
{
public int startingHealth = 100; // The amount of health the player starts the game with.
public int currentHealth; // The current health the player has.
public Slider healthSlider; // Reference to the UI's health bar.
public Image damageImage; // Reference to an image to flash on the screen on being hurt.
public AudioClip deathClip; // The audio clip to play when the player dies.
public float flashSpeed = 5f; // The speed the damageImage will fade at.
public Color flashColour = new Color(1f, 0f, 0f, 0.1f); // The colour the damageImage is set to, to flash.
Animator anim; // Reference to the Animator component.
AudioSource playerAudio; // Reference to the AudioSource component.
PlayerMovement playerMovement; // Reference to the player's movement.
PlayerShooting playerShooting; // Reference to the PlayerShooting script.
bool isDead; // Whether the player is dead.
bool damaged; // True when the player gets damaged.
void Awake ()
{
// Setting up the references.
anim = GetComponent <Animator> ();
playerAudio = GetComponent <AudioSource> ();
playerMovement = GetComponent <PlayerMovement> ();
playerShooting = GetComponentInChildren <PlayerShooting> ();
// Set the initial health of the player.
currentHealth = startingHealth;
}
void Update ()
{
// If the player has just been damaged...
if(damaged)
{
// ... set the colour of the damageImage to the flash colour.
damageImage.color = flashColour;
}
// Otherwise...
else
{
// ... transition the colour back to clear.
damageImage.color = Color.Lerp (damageImage.color, Color.clear, flashSpeed * Time.deltaTime);
}
// Reset the damaged flag.
damaged = false;
}
public void TakeDamage (int amount)
{
// Set the damaged flag so the screen will flash.
damaged = true;
// Reduce the current health by the damage amount.
currentHealth -= amount;
// Set the health bar's value to the current health.
healthSlider.value = currentHealth;
// Play the hurt sound effect.
playerAudio.Play ();
// If the player has lost all it's health and the death flag hasn't been set yet...
if(currentHealth <= 0 && !isDead)
{
// ... it should die.
Death ();
}
}
void Death ()
{
// Set the death flag so this function won't be called again.
isDead = true;
// Turn off any remaining shooting effects.
playerShooting.DisableEffects ();
// Tell the animator that the player is dead.
anim.SetTrigger ("Die");
// Set the audiosource to play the death clip and play it (this will stop the hurt sound from playing).
playerAudio.clip = deathClip;
playerAudio.Play ();
// Turn off the movement and shooting scripts.
playerMovement.enabled = false;
playerShooting.enabled = false;
}
public void RestartLevel ()
{
// Reload the level that is currently loaded.
SceneManager.LoadScene (0);
}
}
}
我的敌人攻击代码
using UnityEngine;
using System.Collections;
namespace CompleteProject
{
public class EnemyAttack : MonoBehaviour
{
public float timeBetweenAttacks = 0.5f; // The time in seconds between each attack.
public int attackDamage = 10; // The amount of health taken away per attack.
Animator anim; // Reference to the animator component.
GameObject player; // Reference to the player GameObject.
PlayerHealth playerHealth; // Reference to the player's health.
EnemyHealth enemyHealth; // Reference to this enemy's health.
bool playerInRange; // Whether player is within the trigger collider and can be attacked.
float timer; // Timer for counting up to the next attack.
void Awake ()
{
// Setting up the references.
player = GameObject.FindGameObjectWithTag ("Player");
playerHealth = player.GetComponent <PlayerHealth> ();
enemyHealth = GetComponent<EnemyHealth>();
anim = GetComponent <Animator> ();
}
void OnTriggerEnter (Collider other)
{
// If the entering collider is the player...
if(other.gameObject == player)
{
// ... the player is in range.
playerInRange = true;
}
}
void OnTriggerExit (Collider other)
{
// If the exiting collider is the player...
if(other.gameObject == player)
{
// ... the player is no longer in range.
playerInRange = false;
}
}
void Update ()
{
// Add the time since Update was last called to the timer.
timer += Time.deltaTime;
// If the timer exceeds the time between attacks, the player is in range and this enemy is alive...
if(timer >= timeBetweenAttacks && playerInRange && enemyHealth.currentHealth > 0)
{
// ... attack.
Attack ();
}
// If the player has zero or less health...
if(playerHealth.currentHealth <= 0)
{
// ... tell the animator the player is dead.
anim.SetTrigger ("PlayerDead");
}
}
void Attack ()
{
// Reset the timer.
timer = 0f;
// If the player has health to lose...
if(playerHealth.currentHealth > 0)
{
// ... damage the player.
playerHealth.TakeDamage (attackDamage);
}
}
}
}
我的一位朋友告诉我使用C ++，他发现奇怪的是，在播放器层次结构中，播放器健康是一种资产，可能必须以某种方式直接调用。

问题可能在这里：
if(timer >= timeBetweenAttacks && playerInRange && enemyHealth.currentHealth > 0)
{
// ... attack.
Attack ();
}
对于被敌人攻击的玩家来说，三件事情必须同时成真。
timer必须 或等于 0.5f 。 playerInRange也必须是true。最后enemyHealth.currentHealth必须超过 0 。
一旦您的代码超过 30 ，包含太多C＃脚本，必须知道如何调试您自己的代码。
我最好的猜测是playerInRange永远不会true，这就是为什么攻击而不是被调用的原因。在Debug.Log("Attacked Player");之前添加Attack ();，然后检查＆＃34; 已攻击玩家＆＃34;当敌人攻击玩家时显示。如果不是，那么其中一个是false。
同时添加Debug.Log("Player is in Range");以查看是否正在检测播放器
void OnTriggerEnter (Collider other);功能如下：
void OnTriggerEnter (Collider other)
{
// If the entering collider is the player...
if(other.gameObject == player)
{
// ... the player is in range.
playerInRange = true;
Debug.Log("Player is in Range");
}
}
这些将告诉你场景中发生了什么。

我可以确认代码是否按您提供的方式运行，但需要一组特定情况才能EnemyAttack成功调用PlayerHealth.TakeDamage()：
EnemyAttack所附加的GameObject需要Rigidbody，您可能需要设置 IsKinematic = true Collider组件 - 标有 IsTrigger = true PlayerHealth所附加的GameObject需要Rigidbody和Collider，其中Gameobject的标记设置为＆＃39;播放器＆＃39;，因为您＆＃ 39;已经在你提供的屏幕上证明了我相信您的EnemyAttack未能损坏播放器，因为标记playerInRange始终为false。通过OnTriggerEnter()但不是OnTriggerExit()之前，此标志设置为true。由于组件未在场景中正确设置，因此永远不会调用OnTriggerEnter()。
