RPGDiceCalculator

A Swift Package for creating and rolling dice formulae.

With RPGDiceCalculator you can create both simple and complex dice-based formulae within your application and roll those

Installation

Add this project on your Package.swift

import PackageDescription

let package = Package(
    dependencies: [
        .Package(url: "https://github.com/Michaelcraun/DiceCalc.git", majorVersion: 0, minor: 0)
    ]
)

Alternatively, you can add this package to your Xcode project directly by clicking File > Swift Packages > Add Package Dependency... and pasting the link to this repository (https://github.com/Michaelcraun/DiceCalc.git) in the dialog box.

Usage example

You can use the default layout simply by using the default initializer like so:

import RPGDiceCalculator
import SwiftUI

struct SomeView: View {
    var body: some View {
        DiceCalculatorView()
    }
}

Or you can customize the calculator's appearance using an instance of the DiceCalculatorConfiguration, like so:

import RPGDiceCalculator
import SwiftUI

struct DicePickerView: View {
    var configuration: DiceCalculatorConfiguration {
        DiceCalculatorConfiguration(
            buttonConfiguration: ButtonConfiguration(
                foregroundColor: (normal: .primary, pressed: Color.secondary),
                backgroundColor: (normal: .secondary, pressed: .secondary)),
            formulaFont: .body,
            outputFont: .largeTitle,
            rollButtonTitle: "Finished")
    }
    
    var body: some View {
        DiceCalculatorView(configuration: configuration)
    }
}

There are many more customization options built in to the calculator, so play around with them until you're happy with it's appearance! :)

Using the data

RPGDiceCalculator has two completion handlers for your use: onChange and onRoll. Each of these sends different data back to the receiver and can be implemented with the .onChange(_:) and .onRoll(_:) functions of the data model, like so:

import RPGDiceCalculator
import SwiftUI

struct DicePickerView: View {
    var configuration: DiceCalculatorConfiguration {
        DiceCalculatorConfiguration(
            buttonConfiguration: ButtonConfiguration(
                foregroundColor: (normal: .primary, pressed: Color.secondary),
                backgroundColor: (normal: .secondary, pressed: .secondary)),
            formulaFont: .body,
            outputFont: .largeTitle,
            rollButtonTitle: "Finished")
    }
    
    var viewModel: DiceCalculatorViewModel {
        DiceCalculatorViewModel()
            .onChange { formula in 
                print(formula)
            }
            .onRoll { roll in 
                print(roll)
            }
    }
    
    var body: some View {
        DiceCalculatorView(viewModel, configuration: configuration)
    }
}

Limitations

Number of Dice. While testing, I found that a number of dice with 6 or more digits took almost a full second to calculate the rolls, so numbers with more than 5 digits have been disabled within this project. When the user attempts to enter a 6th digit while using the calculator, nothing happens.
