MKGameController

A simple Direction pad touch controller for SpriteKit games.

How to use?

• Instantiate an instance of TouchControllerNode and add it to the camera node in your scene.

  let controllerNode = TouchControllerNode(frame: ...)
  scene.camera.addChild(controllerNode)

• TouchControllerNode handles the layout for D-Pad Direction and Action keys.

  Assign a delegate to TouchControllerNode's inputDelegate property.

  controllerNode.inputDelegate = objectThatConformsToInputDelegate

• When a key action occurs, a command is sent to the delegate.

  Handle the command, to perform actions according to your game logic.

  func handle(command: InputCommand) {
      switch command {
      case .hold(let inputKey):
          // input key pressed
          ...
          
      case .cancel(let inputKey):
          // input key press cancelled
          ...
          
      case .release(let inputKey):
          // input key released
          ...
      }
  }

• Supported Keys are defined in InputKey

• Supported Actions are defined in InputCommand

• Images for D-pad Keys are present in Images.xcassets.

Note:

• Enable multiple touches on SKView that will present the D-Pad controller node.

  It is important to enable multiple touch on the SKView that will present the scene to whose camera the D-Pad controller node will be added. Else multiple touch events will not be delivered when two (or more) buttons are pressed simultaneously

  camera.scene.view.isMultipleTouchEnabled = true
