我正在使用 Unity 的生存射击游戏资源构建一个多人游戏,玩家是使用场景中的网络管理器生成的预制件,并具有标记播放器。敌人由敌人管理器生成和管理,该管理器搜索玩家标签并使敌人成为玩家的目标,但敌人只攻击生成第一个的玩家,不会攻击之后生成的玩家。
敌人管理器脚本
public class EnemyManager : MonoBehaviour
{
PlayerHealth playerHealth; // Reference to the player's heatlh.
public GameObject enemy; // The enemy prefab to be spawned.
public float spawnTime = 3f; // How long between each spawn.
public Transform[] spawnPoints; // An array of the spawn points this enemy can spawn from.
void Start ()
{
// Call the Spawn function after a delay of the spawnTime and then continue to call after the same amount of time.
playerHealth = GameObject.FindWithTag("Player").GetComponent<PlayerHealth>();
InvokeRepeating ("Spawn", spawnTime, spawnTime);
}
void Spawn ()
{
// If the player has no health left...
if(playerHealth.currentHealth <= 0f)
{
// ... exit the function.
return;
}
// Find a random index between zero and one less than the number of spawn points.
int spawnPointIndex = Random.Range (0, spawnPoints.Length);
// Create an instance of the enemy prefab at the randomly selected spawn point's position and rotation.
Instantiate (enemy, spawnPoints[spawnPointIndex].position, spawnPoints[spawnPointIndex].rotation);
}
}
敌人攻击脚本
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);
}
}
}
敌人运动
public class EnemyMovement : MonoBehaviour
{
Transform player; // Reference to the player's position.
PlayerHealth playerHealth; // Reference to the player's health.
EnemyHealth enemyHealth; // Reference to this enemy's health.
NavMeshAgent nav;
void Awake ()
{
// Set up the references.
player = GameObject.FindGameObjectWithTag ("Player").transform;
playerHealth = player.GetComponent<PlayerHealth>();
enemyHealth = GetComponent <EnemyHealth> ();
nav = GetComponent <NavMeshAgent> ();
}
void Update ()
{
// If the enemy and the player have health left...
if(enemyHealth.currentHealth > 0 && playerHealth.currentHealth > 0)
{
// ... set the destination of the nav mesh agent to the player.
nav.SetDestination (player.position);
}
// Otherwise...
else
{
// ... disable the nav mesh agent.
nav.enabled = false;
}
}
}
本地播放器设置脚本
public class LocalPlayerSetup : NetworkBehaviour {
void Start()
{
GameObject.FindGameObjectWithTag ("EnemyManager").SetActiveRecursively (true);
if (isLocalPlayer) {
GameObject.FindGameObjectWithTag ("MainCamera").GetComponent<CameraFollow> ().enabled = true;
GetComponent<PlayerMovement> ().enabled = true;
GetComponentInChildren<PlayerShooting> ().enabled = true;
}
}
}
你的代码中有几个问题:
- 您正在 AWAKE 事件中找到玩家(该事件仅在开始(
- 您正在使用FindGameObjectWithTag查找播放器,其中只有返回一个对象。
- 你正在生成没有网络生成的敌人,这不会 在客户端上生成敌人。
复杂问题的通用解决方案:
- 列出玩家列表,并使用调用重复频繁检查玩家及其计数。稍后,使用该列表(玩家列表(攻击玩家。
- 使用FindGameObjectsWithTag查找玩家,它将返回玩家列表。
- 使用网络生成在所有客户端上生成敌人。
