Enum parthia_lib::rng::RNSystem

pub enum RNSystem {
    OneRN,
    FatesRN,
    TwoRN,
}

One of the different RN systems used to compute hits and misses.

Variants

OneRN

The honest approach: a 95% hit rate means a 95% chance of hitting, using a single random number for the calculation.

FatesRN

The hybrid approach used in Fates games: below 50%, one number is used, and above 50% one RNs is used but manipulated in a way that tries to split the difference between the 1RN and 2RN hit rates.

TwoRN

The approach used in most Fire Emblem games: two numbers from 0-100 are used, and the average of those numbers is compared to the hit rate. This means that 90% listed hit rate corresponds to 99% hit rate (the chance two numbers 0-100 average to above 90 is much smaller than a single number being above 90).

Implementations

impl RNSystem

pub fn true_hit(&self, listed_hit: u32) -> f64

Returns the true hit rate, as a number between 0 and 1, for a listed hit rate as described in the enum declaration.
