so i have made mob generator just fine and they spawn but they only spawn once i wonder how i can allow them to spawn every 2 seconds then stop spawning after 10minutes wait 10minutes then spawn a new wave, at the moment it set to random range and selects a mob at random thanks for any help

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class MobGenerator : MonoBehaviour {
public enum State {
Idle,
Initialize,
Setup,
SpawnMob
}
public GameObject mobPrefabs; //array to hold all mob prefabs
public GameObject spawnPoints; //array of spawn points

public State state;

void Awake() {
	state = MobGenerator.State.Initialize;
}
// Use this for initialization
IEnumerator Start () {
	while(true) {
		switch(state) {
		case State.Initialize:
			Initialize();
				break;
		case State.Setup:
			Setup();
				break;
		case State.SpawnMob:
			SpawnMob();
				break;
			
		}
		
		yield return 0;
	}
}
private void Initialize() {
	
	if(!CheckForMobPrefabs())
		return;
	if(!CheckForMobSpawn())
		return;
	
	state = MobGenerator.State.Setup;
}

private void Setup() {
	state = MobGenerator.State.SpawnMob;
}

private void SpawnMob() {
	
	GameObject[] avaliable = AvailableSpawnPoints();
	
	for(int cnt = 0; cnt < avaliable.Length; cnt++) {
		GameObject SpawnMob = Instantiate(mobPrefabs[Random.Range(0, mobPrefabs.Length)],
		                            avaliable[cnt].transform.position,
		                            Quaternion.identity
		                            ) as GameObject;
		SpawnMob.transform.parent = avaliable[cnt].transform;
	
	state = MobGenerator.State.Idle;
}

}

//check for mobs
private bool CheckForMobPrefabs() {
	if(mobPrefabs.Length > 0)
		return true;
	else
		return false;
}

private bool CheckForMobSpawn() {
	if(spawnPoints.Length > 0)
		return true;
	else
		return false;
}

private GameObject[] AvailableSpawnPoints() {
	List<GameObject> avaliable = new List<GameObject>();
	
	for(int cnt = 0; cnt < spawnPoints.Length; cnt++) {
		if( spawnPoints[cnt].transform.childCount == 0) {
			avaliable.Add(spawnPoints[cnt]);
		}
	}
	
	return avaliable.ToArray();
}

}

Add a canSpawn var, and switch it between true to false. It would look like something like that.

var canSpawn : boolean = true;
var spawnTime : float = 600.0;
var spawnClockStart : float = 0.0;
var spawnClockEnd : float = 1.0;
var spawnClockCur : float = 0.0;
var lerpAmt : float = 0.0;

function Update(){
lerpAmt += Time.deltaTime / spawnTime;
	spawnClockCur = Mathf.Lerp (spawnClockStart, spawnClockEnd, lerpAmt);

  if(canSpawn &&
  spawnClockCur <= 1.0){
  canSpawn = false;
  lerpAmt = 0.0;
  spawClockCur = 0.0;
  }
  if(!canSpawn &&
  spawnClockCur <= 1.0){
  canSpawn = true;
  lerpAmt = 0.0;
  spawnClockCur = 0.0;
  }
}

With this, just use the “canSpawn” as the condition to spawn your ennemies.

PS: I’m aware it’s not a “Clean” code, it’s just to show the principle of it.

Hello, i see that you use an FSM here. You can make a new State called “WaitTenMins” or something like that and set it after spawning the mobs. In the function you can try this:

public float waitTime = 10F * 60F; //ten minutes
private float nextWaveTime = 0.0F;

void WaitTenMins() {
    if (Time.time > nextWaveTime) {
        state = MobGenerator.State.SpawnMobs;
    }    
}

Of course you will need to set the nextWaveTime to Time.time + waitTime before you set the state to “WaitTenMins”.
Hope that helps.

I may be able to help, as I have done this in my game, but
I use java script. Do you mind totally changing your script to javascript???
