Hello, I have code that spawns enemies in for loop. Problem is it spawns them all in one place, one solution is to offset spawning position.I did that at some extent, but script that would delay spawning in for random number of milliseconds would do a better job.

I couldn't make yield work, it did increase number of second for loop ran, but enemies still spawned for every

for ( counter=0; counter<currentWaveCount; counter++){
    spawnOffset = transform.position;//reset variable to spawnpoint location
    spawnOffset.x += Random.Range(spawnOffsetMin, spawnOffsetMax);//randomize position of spawning

    Instantiate(enemy, spawnOffset, transform.rotation);//spawn enemy

}

this is for loop I want to introduce time delay between spawns in.

this is whole code.

var waves : String[]; //Array of enemy waves, must be assigned through inspector view. each element of wave array must contain 3 numbers denoted by "," (comma). exm: 7,4,2. first number is time in seconds wave will spawn at, second is number of enemies to spawn in wave, third is randomizator to second number.
var wavesDone : int = 0; //counter for how many waves were already spawned.
var currentWaveTime : int;//extracting current wave spawn time from waves string array for easy of use.
var currentWaveCount : int;//extracting current wave enemy count from waves string array for easy of use.
var enemy: GameObject;//what enemy to spawn.
var noMoreWaves: boolean; //boolean to disable spawnpoint after all waves were spawned
var currentwave:Array ;//ID of current wave
var counter: int;
var spawnOffset: Vector3;//variable used to offset enemy position on X axis when Instantiate-ing it.,
var spawnOffsetMin: float=1.0;
var spawnOffsetMax: float=2.0;



//this code adds icon to spawn point game object, to easily select in scene view
function OnDrawGizmos() {
    Gizmos.DrawIcon(transform.position, "TG_EnemySpawner.tif");
}

//we prepare for next wave, extracting and reseting variables
function NextWave() {
   if (wavesDone<waves.length){ //if waves already done are less then lenght of wave array
      currentwave = waves[wavesDone].Split(","[0]);//extracting variables from waves string for current wave
      currentWaveTime = int.Parse(currentwave[0]);//assigning current wave spawn time
      currentWaveCount = int.Parse(currentwave[1])+Mathf.Round(Random.Range(-int.Parse(currentwave[2]),int.Parse(currentwave[2])));//we assign number of enemies to spawn + random number between(-randomizator,+randomizator) (third number from waves string array)
   }
   else{
            noMoreWaves=true;//if all waves were spawned disable spawner
   }
}
//funtion that spawns  current wave of enemies 
function SpawnWave() {

    for ( counter=0; counter<currentWaveCount; counter++){
        spawnOffset = transform.position;//reset variable to spawnpoint location
        spawnOffset.x += Random.Range(spawnOffsetMin, spawnOffsetMax);//randomize position of spawning

        Instantiate(enemy, spawnOffset, transform.rotation);//spawn enemy

    }
   wavesDone++;
   // Get next wave information
   NextWave();
}

function Start() {
   NextWave();//get info for first wave
}

function Update() {
    if  (noMoreWaves == false){//not all waves were spawned
        if (Level_Attributes.gameTime >= currentWaveTime){//Timer is run from the start of the game, if time has come to spawn current wave 
            SpawnWave();//spawn wave
        }
    }
   print(Level_Attributes.gameTime);//print timer for debug purphoses.
}
