Bag

Provide get item in array with weighted probability.

• Sample 1

var bag = new Bag<string>(
            new BagItem<string> {item = "a", weight = 0.3f},
            new BagItem<string> {item = "b", weight = 0.6f},
            new BagItem<string> {item = "c", weight = 0.14f});

bag.Pick(); // take random item form bag
bag.Pop(); // take random item form bag and remove it

• Sample 2

[SerializeField] private Bag<string> bag; // initialize bag outside inspector

private void Start()
{
    bag.Initialize(); // you need to call Initialize when using inspector to initialize the bag, not new

    bag.Pick(); // take random item form bag
    bag.Pop(); // take random item form bag and remove it
}

• Sample 3

var bag = new Bag<string>(ENumberRoll.Two,
    ERollResultType.Min,
    new BagItem<string> {item = "a", weight = 0.3f},
    new BagItem<string> {item = "b", weight = 0.6f},
    new BagItem<string> {item = "c", weight = 0.14f});

bag.Pick(); // take random item form bag
bag.Pop(); // take random item form bag and remove it

• ENumberRoll : An enum that specifies how many times to roll a random value and then compare it against the ERollResultType to pick the final value.

  • One
  • Two
  • Three

• ERollResultType : Strategy to pick the final value if the number of rolls is greater than one

  • None : Using this option implies that the number roll is one time.
  • Min : Select the smallest value in the rolls
  • Max : Select the largest value in the rolls
  • Sum : The final value will be equal to the sum of the values ​​of all the rolls.

• Graph showing the probability of selection when using None

• Graph showing the probability of selection when using Min

• Graph showing the probability of selection when using Max

• Graph showing the probability of selection when using Sum
