Spawning Object at Random Points in an Array?

Questions & Answers

Hi

Never be taught about arrays in College so everything I know has been crafted together from what I’ve seen and heard. Done loads of googling and haven’t found anything useful of what I want to do.

Got a prefab and want to spawn it random locations. I’ve make a load of spawn points where I wouldn’t mind it spawning so I decided to put them in an array. I’ve seen a few ways to pick a random value from an array but won’t work with mine.

I have set the array up with find with tags so i just need it to randomly pick a transform from that array.

Can anyone help please.

    public GameObject hazard; 
	public GameObject[] hazardSpawn;

	public int hazardCount;
	public int multiply = 2;
	public float spawnWait;
	public float startWait;
	public float waveWait;
	
	void Start ()
	{
		hazardSpawn = GameObject.FindGameObjectsWithTag ("HazardSpawn");

		StartCoroutine (SpawnWaves ());
	}
	
	IEnumerator SpawnWaves ()
	{
		yield return new WaitForSeconds (startWait);
		while (true)
		{
			for (int i = 0; i < hazardCount; i++)
			{

				Transform spawnPoint = hazardSpawn[Random.Range(0, hazardSpawn.Length)]; //this is what I tried
				Quaternion spawnRotation = Quaternion.identity;
				Instantiate (hazard, hazardSpawn, spawnRotation);

				yield return new WaitForSeconds (spawnWait);
			}
			//hazardCount needs to be multiplied here (my little reminder)

			yield return new WaitForSeconds (waveWait);
		}
	}
}

This snippet is not actually using the position of your spawnPoint:

Transform spawnPoint = hazardSpawn[Random.Range(0, hazardSpawn.Length)]; //this is what I tried
Quaternion spawnRotation = Quaternion.identity;
Instantiate (hazard, hazardSpawn, spawnRotation);

Try passing these values to your Instantiate() call:

Instantiate (hazard, spawnPoint.position, spawnRotation);
