How to check if a game object is destroyed from array? And instantiate a new game object when a game object is destroyed?
So I want to be able to know if a game object is destroyed from an array and the array count will be for example is 5, when a game object is destroyed, the count will be then be reduced to four. And if the count is less than 5, I want to be able to instantiate another game object.
This is my code.
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class SpawnEnemy : MonoBehaviour {
public GameObject[] go;
public Vector3 spawnPosition;
public int spawnLimit;
public int spawnCount;
public bool spawn;
public float waitTime;
public float timer;
void Start(){
}
void Update(){
if(spawn){
timer += Time.deltaTime;
if (timer > waitTime) {
if (spawnCount < spawnLimit) {
Spawn ();
timer = 0.0f;
} else {
spawn = false;
Debug.Log ("Spawn limit has been reached!");
}
}
}
}
void Spawn(){
GameObject gos = go [Random.Range(0, go.Length)];
Instantiate (gos, spawnPosition, Quaternion.Euler (90, 0, 0));
spawnCount++;
Debug.Log ("Spawned game object #" + spawnCount);
}
}
@yasssrenaeXD - Use List ins$$anonymous$$d of Array, then you can it's count and length easily.
You could create another script assignable to the spawned object that notifies SpawnEnemy when it's destroyed (or just handle it inside your enemy AI script when it dies/is destroyed).
Here would be your SpawnEnemy:
using UnityEngine;
public class SpawnEnemy : MonoBehaviour
{
public GameObject[] go;
public Vector3 spawnPosition;
public int spawnLimit;
public float waitTime;
bool spawn;
float timer;
int spawnCount;
void Update()
{
if (spawn)
{
timer += Time.deltaTime;
if (timer > waitTime)
{
if (spawnCount < spawnLimit)
{
Spawn();
timer = 0.0f;
}
else
{
spawn = false;
Debug.Log("Spawn limit has been reached!");
}
}
}
}
void Spawn()
{
GameObject gos = go[Random.Range(0, go.Length)];
GameObject spawned = Instantiate(gos, spawnPosition, Quaternion.Euler(90, 0, 0));
spawnCount++;
SpawnedObject spawnedObject = spawned.AddComponent<SpawnedObject>();
spawnedObject.spawner = this;
Debug.Log("Spawned game object #" + spawnCount);
}
public void Despawn()
{
spawnCount--;
spawn = true;
}
}
and here is a sample script to notify SpawnEnemy:
using UnityEngine;
public class SpawnedObject : MonoBehaviour
{
public SpawnEnemy spawner;
void OnDestroy()
{
if (spawner != null)
spawner.Despawn();
}
}
