重复价值统一

Question

它应该给我一个随机值丢失。它或者给我-.75或.75作为缺失而不是输出列表中的任何值。

var Rando : float;
function Start () {
   Amount = Random.Range(8,9);
    while (Amount > 0) { //CREATING THE BLOCKS
        Rando = (-27.0f + (Random.Range(0,9) * 6.0f)) / 4.0f;
        while (AmountArray.Contains(Rando)) {
            Rando = (-27.0f + (Random.Range(0,9) * 6.0f)) / 4.0f;
        }
        AmountArray.Add (Rando);
        Amount--;
    }
    AmountArray.Clear();
}
