# Dice roller

Contribution by Griatch, 2012

A dice roller for any number and side of dice. Adds in-game dice rolling (`roll 2d10 + 1`) as well as conditionals (roll under/over/equal to a target) and functions for rolling dice in code. Command also supports hidden or secret rolls for use by a human game master.

## Installation:

Add the `CmdDice` command from this module to your character’s cmdset (and then restart the server):

    # in mygame/commands/default_cmdsets.py

    # ...
    from evennia.contrib.rpg import dice  <---

    class CharacterCmdSet(default_cmds.CharacterCmdSet):
        # ...
        def at_object_creation(self):
            # ...
            self.add(dice.CmdDice())  # <---

## Usage:

    > roll 1d100 + 2
    > roll 1d20
    > roll 1d20 - 4

The result of the roll will be echoed to the room

One can also specify a standard Python operator in order to specify eventual target numbers and get results in a fair and guaranteed unbiased way. For example:

    > roll 2d6 + 2 < 8

Rolling this will inform all parties if roll was indeed below 8 or not.

    > roll/hidden

Informs the room that the roll is being made without telling what the result was.

    > roll/secret

Is a hidden roll that does not inform the room it happened.

### Rolling dice from code

To roll dice in code, use the `roll` function from this module:

    from evennia.contrib.rpg import dice
    dice.roll(3, 10, ("+", 2))  # 3d10 + 2
