Question by Kevbot3000 · Apr 19, 2017 at 11:43 AM · while-loop

While loop Crash

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

public class Spawner : MonoBehaviour {

 public Wave[] waves;
 public Vector3[] spawnPos;



 Wave currentWave;
 int currentWaveNumber;
 int waveSize;
 int i;
 int k;
 int p;



 int [] enemiesRemainingToSpawn = new int[20];
 int enemiesRemainingAlive;
 float nextSpawnTime;



 void Start (){
     i = 0;
     k = 0;
     p = 0;
     waveSize = spawnPos.Length;
     NextWave ();
     StartCoroutine (SpawnEnemies ());

 }

 voidUpdate(){
     
 
 }

 IEnumerator SpawnEnemies(){

     while ( i <= currentWave.enemyType.Length){

         while (k <= currentWave.enemyCount[i]  ){

             if (enemiesRemainingToSpawn[i] > 0 ) {    
                 enemiesRemainingToSpawn[i]--;
                 nextSpawnTime = currentWave.timeBeetweenSpawns;

                 LivingEntities spawnedEnemy = Instantiate (currentWave.enemyType [i], spawnPos [Random.Range (0, waveSize)], Quaternion.identity) as LivingEntities;
                 spawnedEnemy.OnDeath += OnEnemyDeath;
                 k++;
                 yield return new WaitForSeconds (nextSpawnTime);
             
             }


         }

         i++;
     }

 
 
 }

 void NextWave() {
     currentWaveNumber++;
     if (currentWaveNumber - 1 < waves.Length){
     currentWave = waves [currentWaveNumber - 1];

         while (p <= currentWave.enemyCount.Length - 1){

             enemiesRemainingToSpawn[p] = currentWave.enemyCount[p];
             print("1");
             enemiesRemainingAlive = enemiesRemainingAlive + enemiesRemainingToSpawn[p];
             p++;
         
         }
     }
     i = 0;
     k = 0;
     p = 0;
 }


 void OnEnemyDeath()
 {
     enemiesRemainingAlive--;

     if (enemiesRemainingAlive == 0) {
         NextWave ();
     }
 }

 [System.Serializable]
 public class Wave {
     public int[] enemyCount;
     public float timeBeetweenSpawns;
     public LivingEntities[] enemyType;
 }

}

the SpawnEnemies Coroutine is the one that has a problem, could someone please help? I don't know why it isnt working.

What kind of crash are you having? What isn't working?

$$anonymous$$ost probably the if statement never gets true so it stacks in the loop, to check if this is the issue add a yield return inside the second while and outside the if and a couple Debug.Logs to see what values doesn't change as expected also if that fails add another yield return in the first while plus some debugs. Eventually you ll fiure out what s going wrong.
