Dice Tower

A PHP library for "rolling" n dice, with n sides each.

Generates cryptographic random integers for unbiased results.

Installation

composer require joshbruce/php-dice-tower

Usage

Say you are rolling a character for an RPG using a fairly standard method (4d6, drop the lowest).

use JoshBruce\DiceTower\DicePool;

DicePool::roll4d6()->highest(3)->sum();
// step 1: [3, 5, 2, 1]
// step 2: [5, 3, 2]
// step 3: 10

You do not need to use the magic static method:

use JoshBruce\DiceTower\DicePool;

DicePool::roll(4, 6)->highest(3)->sum();
// step 1: [3, 5, 2, 1]
// step 2: [5, 3, 2]
// step 3: 10

You can also roll a single die using one of the following:

use JoshBruce\DiceTower\DicePool;

DicePool::roll();
// rolls 1d6

DicePool::roll(1, 6);
// rolls 1d6

use JoshBruce\DiceTower\Dn;

Dn::withSides();
// roll 1 die with the given number of sides

The values of the rolls are calculated at instantiation. Therefore, the various fluent methods are about manipulating the initial results or retrieving values from them.

Details

Effectively this is a random number generator using cryptographic random integers suitable for use where unbiased results are critical (random_int). The minimum value is always 1.

Inspired by AnyDice and driven by the desire to create an MORPG using various dice-based systems; specifically 7DSystem and the Cypher System.
