Infinite Instantiation

Question

I am instantiating enemies. My if-statement should close itself as soon as one appears, but for some reason it repeats itself over a hundred times before stopping.

Just a note about the code, I only have this code on a single game object and don't instantiate in any other scripts, so it isn't the typical issue where clones are creating clones. Additionally, the editor correctly shows the enemyCount at any given time. Despite the fact that enemyCount increases above 1, clones are still generated.

I'm quite new to Unity and C#, so I'm not sure if there's something obvious I'm just missing or if there's some complex reasoning behind the issue. If anyone knows what I can do to fix this, please let me know, it would be greatly appreciated :)

 void Update ()
 {
     if( enemyCount<1 )
         Invoke("RespawnEnemies", 2);
 }

 void RespawnEnemies ()
 {
     enemyCount ++;
     int randomEnemy = Random.Range( 0 , enemySpawnPoints.Length-1 );
     Instantiate( enemySpawnPoints[randomEnemy] , transform.position , Quaternion.identity );
 }

Using Invoke is causing this issue.

Call the method directly instead & you can use a countdown timer to space out the spawning of the enemies so they don't spawn in too quickly.

So if the enemyCount is less then 1 start a timer that counts down from 2 seconds. When the timer reaches 0 then run RespawnEnemies() & reset the timer.

Thanks, I think both of these solutions work great! I hadn't thought of Evoke being the issue, so this was a ton of help :)
