    fn generate_model(

Defines how casuality works inside the battle system.

Entropy must be deterministic. If you use a generator, make sure that by starting from an identical seed the same sequence of random bits will be reproduced.

Associated Types

Required methods

fn generate_model(&self, seed: &Option<Self::EntropySeed>) -> Self::EntropyModel

Generates an EntropyModel starting from an EntropySeed.

fn generate(
    &self,
    model: &mut Self::EntropyModel,
    low: Self::EntropyOutput,
    high: Self::EntropyOutput
) -> Self::EntropyOutput

Generates a random value within a half-open range [low, high).

high is guaranteed to be greater or equal to low.
