how to: continue invoking when the first object is destroyed
Hello
i am trying to make a game that spawn monsters (using C#)
and this what i want: 1-invoke monster 2-check if the monster is dead 2a-if dead continue invoking 2b-if not dead stop invoking
i mean by "dead" gameobject is destroyed
did some codes but didnt work :(
i am using prefab to summon mobs and i tried the (if monster==null) but it doesnt work
can anyone help me please?
You don't need invoke, you need a coroutine. Simply keep a reference to the last clone and check if it has been destroyed.
public GameObject monsterPrefab;
IEnumerator Spawn (){
GameObject clone;
while (true){
while (clone){
yield return null;
}
clone = (GameObject)Instantiate(monsterPrefab);
}
}
is there any other way?
cause i dont know corutine and enumerator :(
There are other ways. @dmg0600 provided one solution. It can also be done with Update as follows
public GameObject monsterPrefab;
GameObject clone;
void Update () {
if (!clone){
clone = (GameObject)Instantiate(monsterPrefab);
}
}
But coroutines are really worth learning. Its one of Unity's more powerful features.
thank you for your comment
but can u answer these 2 questions please?
1-is clone normal gameobject {monster} or its the object spawning {monster(clone)}
2-the if statment doesnt work cause my gameobject is a prefab and it is always not null
Thank you very much
Clone is not your prefab. Clone should be the actual GameObject in the scene. Hence the clone = Instantiate line.
Note my answer is pseudo code. Its meant to demonstrate a point, you can't copy it literally.
If you don't want to do it with coroutines and you don't care that the new enemy could appear after some time you can do it with InvokeRepeating:
public GameObject monsterPrefab;
public float respawnCheckTime = 5.0f;
private GameObject clone;
void Start()
{
...
InvokeRepeating("RespawnEnemy", 0, respawnCheckTime);
}
void RespawnEnemy()
{
if (clone == null)
{
clone = Instantiate(monsterPrefab) as GameObject;
}
}
This will check every respawnCheckTime if the last enemy spawned is alive, if not it will isntantiate a new one. Pretty much what @BoredMormon code does but with InvokeRepeating instead of coroutines.

Same answer as @Bored$$anonymous$$ormon I will also edit my answer with a variable for the prefab for future reference.
