getWeightedInventoryItem(itemArray: { [tplId: string]: unknown; } | ArrayLike<unknown>): stringgetWeightedValue<T>(itemArray: { [key: string]: unknown; } | ArrayLike<unknown>): T
Choos an item from the passed in array based on the weightings of each
reduceWeightValues(weightedDict: Record<string, number>): void
Find the greated common divisor of all weights and use it on the passed in dictionary
weightedRandom(items: any[], weights: any[]): { item: any; index: number; }
Picks the random item based on its weight. The items with higher weight will be picked more often (with a higher probability).
For example:
- items = ['banana', 'orange', 'apple']
- weights = [0, 0.2, 0.8]
- weightedRandom(items, weights) in 80% of cases will return 'apple', in 20% of cases will return 'orange' and it will never return 'banana' (because probability of picking the banana is 0%)
