So the enemy waves were working before the loop was made (and I can roll back and make them work again) but after we changed the void Start() to IEnumerable Start(), no error is thrown, but no enemies spawn, I’m not really sure what’s wrong.
Going to add some code blocks here (not really sure what is wrong so… be ready for a big wall)
EnemySpawner code
public class EnemySpawner : MonoBehaviour
{
[SerializeField] List<WaveConfig> waveConfigs;
[SerializeField] int startingWave = 0;
[SerializeField] bool looping = false;
// Start is called before the first frame update
IEnumerable Start()
{
do
yield return StartCoroutine(SpawnAllWaves());
while (looping);
}
private IEnumerator SpawnAllWaves()
{
for (int waveIndex = startingWave; waveIndex < waveConfigs.Count; waveIndex++)
{
var currentWave = waveConfigs[waveIndex];
yield return StartCoroutine(SpawnAllEnemiesInWave(currentWave));
}
}
private IEnumerator SpawnAllEnemiesInWave(WaveConfig waveConfig)
{
for (int enemyCount = 0; enemyCount < waveConfig.GetNumberOfEnemies(); enemyCount++)
{
var newEnemy = Instantiate(
waveConfig.GetEnemyPrefab(), waveConfig.GetWaypoints()[0].transform.position, Quaternion.identity);
newEnemy.GetComponent<EnemyPathing>().SetWaveConfig(waveConfig);
yield return new WaitForSeconds(waveConfig.GetTimeBetweenSpawns());
}
}
}
Wave Config Code
[CreateAssetMenu(menuName = "Enemy Wave Config")]
public class WaveConfig : ScriptableObject
{
[SerializeField] GameObject enemyPrefab;
[SerializeField] GameObject pathPrefab;
[SerializeField] float timeBetweenSpawns = .5f;
[SerializeField] float spawnRandomFactor = .3f;
[SerializeField] int numberOfEnemies = 5;
[SerializeField] float moveSpeed = 2f;
public GameObject GetEnemyPrefab() { return enemyPrefab; }
public List<Transform> GetWaypoints()
{
var waveWaypoints = new List<Transform>();
foreach (Transform child in pathPrefab.transform)
{
waveWaypoints.Add(child);
}
return waveWaypoints;
}
public float GetTimeBetweenSpawns() { return timeBetweenSpawns; }
public float GetSpawnRandomFactor() { return spawnRandomFactor; }
public int GetNumberOfEnemies() { return numberOfEnemies; }
public float GetMoveSpeed() { return moveSpeed; }
}
EnemyPathing Code
public class EnemyPathing : MonoBehaviour
{
WaveConfig waveConfig;
List<Transform> waypoints;
int waypointIndex = 0;
// Start is called before the first frame update
void Start()
{
waypoints = waveConfig.GetWaypoints();
transform.position = waypoints[waypointIndex].transform.position;
}
// Update is called once per frame
void Update()
{
Move();
}
public void SetWaveConfig(WaveConfig waveConfig)
{
this.waveConfig = waveConfig;
}
private void Move()
{
if (waypointIndex <= waypoints.Count - 1)
{
var targetPosition = waypoints[waypointIndex].transform.position;
var movementThisFrame = waveConfig.GetMoveSpeed() * Time.deltaTime;
transform.position = Vector2.MoveTowards(transform.position, targetPosition, movementThisFrame);
if (transform.position == targetPosition)
{
waypointIndex++;
}
}
else
{
Destroy(gameObject);
}
}
}
I’m really not sure WHY it broke… it kind of just did.
For reference, I’m able to change to a void again (using comments) and it works for one run of wave 1-4.
public class EnemySpawner : MonoBehaviour
{
[SerializeField] List<WaveConfig> waveConfigs;
[SerializeField] int startingWave = 0;
[SerializeField] bool looping = false;
// Start is called before the first frame update
void Start()
{
//do
//yield return
StartCoroutine(SpawnAllWaves());
//while (looping);
}
private IEnumerator SpawnAllWaves()
{
for (int waveIndex = startingWave; waveIndex < waveConfigs.Count; waveIndex++)
{
var currentWave = waveConfigs[waveIndex];
yield return StartCoroutine(SpawnAllEnemiesInWave(currentWave));
}
}
private IEnumerator SpawnAllEnemiesInWave(WaveConfig waveConfig)
{
for (int enemyCount = 0; enemyCount < waveConfig.GetNumberOfEnemies(); enemyCount++)
{
var newEnemy = Instantiate(
waveConfig.GetEnemyPrefab(), waveConfig.GetWaypoints()[0].transform.position, Quaternion.identity);
newEnemy.GetComponent<EnemyPathing>().SetWaveConfig(waveConfig);
yield return new WaitForSeconds(waveConfig.GetTimeBetweenSpawns());
}
}
}
