Simple Homebrew RPG Calculator

A simple calculator used in my homebrew rpg made to facilitate some of the more annoying calculations. Written in rust.

Compiling

Just do a cargo build inside the project and you should be fine. Remember you need to have cargo installed in your path. For more information on how to install rust see: Rust language and install guide.

Requirements

You need a file in the same directory of the program that contain all the magics you have access to. It should be named init.rpg.

Init Schema

The init.rpg file have the following schema:

register <magic_name>
{
    rank <unsigned int>
    type <ORDER | CHAOS>
    always_def <bool>
    table_addon <int>
    race_mult <float>
}

• magic_name : the name of your magic.
• rank : is your current magic rank. It should be between 0 and 5.
• type : should be your magic origin.
• always_def : whether to always treat that magic as defensive.
• table_addon : the value to add to the default accuracy when plotting a table.
• race_mult : the multiplier that your race may have with this magic.

Example:

register fire
{
    rank 0
    type ORDER
    always_def false
    table_addon 0
    race_mult 1.2
}

Using the calculator

Magical Functions

• To see the basic usage do: <magic_name>().
• To see the plotted table usage do: t_<magic_name>().
• To see the defensive mode usage do: def_<magic_name>(). Only available if always_def is false.
• To see the plotted table for the defensive mode usage do: t_def_<magic_name>(). Only available if always_def is false.

Also, if your magic is always_def and you want to see the attack the attack usage you do as follows:

• To see the attack usage do: at_<magic_name>().
• To see the attack plotted table usage do: t_at_<magic_name>().

Common Calculator Things

As a calculator the program can also compute any kind of expressions that a calculator is able to handle. You can also initialize variables python-like like so: a = 12. That means that a variable called a was initialized withe the value 12. That variable may be used in any function. So given a magic name fire, you may do fire(a, a) which will output the fire magic with the accuracy of 12 and 12 mana spent on it.
