Function weightedRandom

weightedRandom<T extends { probWeight: sohl.entity.modifier.ValueModifier }>(
items: T[],
rng?: Rng,
): T
Select a random item from an array, weighted by each item's probWeight property. Items with higher weights are proportionally more likely to be selected.
Type Parameters
- T extends { probWeight: sohl.entity.modifier.ValueModifier }
Parameters
- items: T[]
  Candidate items, each carrying a probWeight modifier.
- rng: Rng = ...
  The random source; defaults to the shared sohl.random singleton. Inject a seeded sohl.entity.random.createRng instance to make selection reproducible (or force it deterministically end to end).
Returns T
The randomly selected item.

Throws
If the array is empty or all weights are zero.
