Simplifying Game Controller Integration with GameControllerKit
In the ever-evolving world of game development, integrating game controllers across multiple platforms can be a difficult task.
Enter GameControllerKit, a Swift package designed to streamline this process for developers working on iOS, macOS, and tvOS.
Let's dive into what makes this toolkit a game-changer.
What is GameControllerKit?
GameControllerKit is an open-source Swift package that simplifies the process of connecting and interacting with game controllers.
Whether you're developing for iOS, macOS, or tvOS, this toolkit provides a unified API to handle game controller inputs, control lights, and manage haptic feedback.
Key Features
-
Easy Connection Management: GameControllerKit makes it straightforward to interact with game controllers. The package handles the (dis)connections of game controllers, allowing developers to focus on gameplay rather than handling game controller conntections and setups.
-
Unified Input Handling: With a simple and intuitive API, developers can easily read inputs from various game controllers. This includes buttons, joysticks, and other control mechanisms, ensuring a seamless gaming experience across different devices.
-
Advanced Control Options: Beyond basic input handling, GameControllerKit allows developers to control the lights and haptics of connected controllers. This feature can be used to enhance the gaming experience by providing visual and tactile feedback to players.
-
Cross-Platform Support: One of the standout features of GameControllerKit is its support for multiple Apple platforms. Whether you're developing a game for iOS, macOS, or tvOS, this toolkit ensures consistent controller behavior across all devices.
Getting Started
To get started with GameControllerKit, you can add it to your project using Swift Package Manager. Here’s a quick guide:
-
Add the Package: In Xcode, go to
File > Swift Packages > Add Package Dependency
and enter the repository URL:https://github.com/0xWDG/GameControllerKit
. -
Import the Package: In your Swift files, import GameControllerKit to access its features:
import GameControllerKit
-
React to Controllers: Use the provided API to connect to game controllers and handle inputs:
let controller = GameControllerKit() gameController.set(handler: { button, pressed, controller in // Handle controller input })
Demo Application
import SwiftUI
import GameControllerKit
struct ContentView: View {
/// The game controller kit
@State
var gameController = GameControllerKit()
/// Log
@State
var log: [String] = []
var body: some View {
VStack {
Button {
gameController.set(color: .GCKRandom)
} label: {
Text("Random Color")
}
Text("Controller: \(gameController.controller?.productCategory ?? "None"), " +
"\((gameController.controllerType ?? .generic).description)")
Text("Last action:\n\(String(describing: gameController.lastAction)).")
GCKControllerView()
.environmentObject(gameController)
List {
ForEach(log.reversed(), id: \.self) { text in
Text(text)
}
}
}
.padding()
.onAppear {
gameController.set(handler: handler)
}
}
/// Handler
///
/// - Parameters:
/// - action: action
/// - pressed: is the button pressed?
/// - controller: which controller?
public func handler(
action: GCKAction,
pressed: Bool,
controller: GCKController
) {
log.append(
"\(String(describing: action))(\(action.position.arrowRepresentation)) \(pressed ? "Pressed" : "Unpressed"), " +
"Controller #id \(String(describing: controller.playerIndex.rawValue))"
)
if action == .buttonA && pressed {
// set to a random color
gameController.set(color: .GCKRandom)
}
}
}
