[英]How to make enemy attack all the player?
I am building a multiplayer game using unity's survival shooter asset, the player is prefab spawned using network manager in the scene and has tag Player .The enemies are spawned and managed by Enemy Manager that searches for the Player tag and makes enemy target the player,but the enemy only attack the player which is spawned 1st and does not attack the players spawned afterwards.我正在使用 unity 的生存射击游戏资产构建多人游戏,玩家是在场景中使用网络管理器预制生成的,并带有标签Player 。敌人由敌人管理器生成和管理,敌人管理器搜索玩家标签并使敌人瞄准玩家,但是敌人只会攻击第一个生成的玩家,不会攻击之后生成的玩家。
EnemyManager Script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);
}
}
