2 "Shadowrun"

(require (planet "shadowrun.ss" ("murphy" "rpg-utils.plt" 1 0)))

Specific procedures for the "Shadowrun" role playing game system.

(cd6 [generator]) → exact-positive-integer?

generator   :   pseudo-random-generator?       =   (current-pseudo-random-generator)

Simulates a cumulative D6 dice roll and returns a random natural number.

A PRNG to use may optionally be specified via the generator argument.

(simulate-test skill target [generator]) → test-result?

skill : exact-nonnegative-integer?

target : exact-nonnegative-integer?

generator   :   pseudo-random-generator?       =   (current-pseudo-random-generator)

Simulates a skill test. The value of the skill or attribute is given by skill, the difficulty of the test by target.

You may optionally specify a PRNG to use via the generator argument.

This procedure returns a test-result structure with the number of successes as its value.

(analyze-test skill target) → test-statistics?

skill : exact-nonnegative-integer?

target : exact-nonnegative-integer?

Determines the statistical properties of a skill test. The value of the skill or attribute is given by skill, the difficulty of the test by target.

This procedure returns a test-statistics structure with the expected number of successes as its expectation.
