Hi! you’ll see, i have this scripts that i made, i have 8 letters i wanna spawn in 11 possible spots, i want each letter to be assign to one unique location, but when i run the script, some letters are spawned at the same spot. What am i doing wrong? :I Thnks! :b

var letter : GameObject[]; //prefabs that will be spawned

var letterSpot : GameObject[]; //Empty GameObjects where the prefabs will spawn
var spotUsed : boolean[]; //wether the spot is already used or not

private var letterIndex : int;


function Start ()
{
	PutLetter(0);
	PutLetter(1);
	PutLetter(2);
	PutLetter(3);
	PutLetter(4);
	PutLetter(5);
	PutLetter(6);
	PutLetter(7);

	
}

function PutLetter (i : int)
{
		letterIndex = Random.Range(0,10);
	while (spotUsed == true)
	{
		letterIndex = Random.Range(0,10);
	}
	Instantiate(letter*, letterSpot[letterIndex].transform.position, letterSpot[letterIndex].transform.rotation);*
  • spotUsed[letterIndex]=true;*
    }

You have to check that specific index in spotUsed to see if it is true. You might also have to initialize the spotUsed array to have a value of false.

while (spotUsed == true)

should be:

while (spotUsed[letterIndex] == true)
