                Unit.transform.localPosition = (i + 1f) * new Vector3(gap, 0, 0);
                units.Add(Unit);
            }

            oldNumberOfUnits = numberOfUnits;
        }
    }
}

I tried inside the Update this :

I want that if I move the gap slider range to the right that it will add more gaps between the existing units and new units if adding new units.

if(gap > oldGapValue)
            {
                for(int i = 0; i < numberOfUnits; i++)
                {
                    units(i).transform.position = (i + 1f) * new Vector3(gap, 0, 0);
                }
    
                oldGapValue = gap;
            }

but this part of code does nothing it’s not adding any gaps and I’m not sure also how to remove gaps if moving the rang slider to the left for example if the gap value is 50 and I removed it to the left and now the gap value is 23 then the gaps should be now 23 between the existing units and if adding new units then add 23 gap between each new unit.
