Rarity function

[E2-waite]

• Store a rarity int in each Interaction class instance.

Choosing object based on rarity:

• Create empty list of Interaction objects
• Add rarity number of instances of Interaction objects
• Get random int index in list range
• Return Interaction objects at the position of the random index

This can allow for different rarity values in different areas with different rarity values.

[E2-waite]

Use: List<int> listFullOfInts = Enumerable.Repeat(42, 50).ToList();

and listFullOfInts.AddRange(Enumerable.Repeat(42, 50));
