Switch spawn position of tiles

Hello!

I am making a sidescroller game with random terrain. I have made a function which spawns tiles at four random y-coordinates. What i want to implement so that a new set of tiles cant spawn at the y-coordinate that the previous set of tiles has spawned on.

This is my code for the function:

void Spawntiles(){

		GameObject[] temp = new GameObject[randLength];
		newTiles = temp;

		randLength = Random.Range(minLength,maxLength);
		index = Random.Range (0, y.Length);
		holeChance = Random.Range (1, 7);
		
		for (int i = 0; i < newTiles.Length; i++){
			newTiles *= Instantiate(plainTile,new Vector3(lastTile.transform.position.x+x+2.2f,y[index].position.y,0),transform.rotation) as GameObject;*

  •  	x = x + 2.4f;*

  •  }*

  •  spawnTiles = false;*

  •  lastTile = newTiles [newTiles.Length-1];*

  • }*
    The y coords are given by four public empty gameobjects that are positioned at the desired spawnpoints. These are in an array. The line index = Random.Range (0, y.Length); picks a number which is then used in the for loop to choose the gameobject of which the tile spawns on: y[index].position.y.
    Anyway, if someone has done anything like this or can come up with something id appretiate the input.
    Thank you!

You could create a list of the currently used positions and when generating a new position check to see if it’s already been used if so just generate and check again!
