How to roll a dice using GameplayKit and GKRandomDistribution
Swift version: 5.0
GameplayKit's random number generator includes help constructors that produces numbers in a specific range, simulating a six-sided die and a 20-sided die. To get started you should import the GameplayKit framework like this:
import GameplayKitYou can then create a virtual six-sided die and "roll" it like this:
let d6 = GKRandomDistribution.d6()
d6.nextInt()For a 20-sided die, do this:
let d20 = GKRandomDistribution.d20()
d20.nextInt()If you want to set your own range for the virtual die, there's a special constructor just for you:
let massiveDie = GKRandomDistribution(lowestValue: 1, highestValue: 556)
massiveDie.nextInt()LEARN SWIFTUI FOR FREE I wrote a massive, free SwiftUI tutorial collection, and also have a growing list of free SwiftUI tutorials on YouTube – get started today!
