Types

type ControlScheme

type ControlScheme struct {
	UP     int
	DOWN   int
	LEFT   int
	RIGHT  int
	A      int
	B      int
	START  int
	SELECT int
}

type CoreIO

type CoreIO struct {
	OnCloseHandler func()
	KeyHandler     *KeyHandler
	StopChannel    chan int
	Headless       bool
	// contains filtered or unexported fields
}

CoreIO contains all core functionality for running the IO event loop all sub types should extend this type

func NewCoreIO

func (*CoreIO) GetKeyHandler

func (i *CoreIO) GetKeyHandler() *KeyHandler

GetKeyHandler returns the key handler component for managing interactions with the keyboard

func (*CoreIO) GetScreenOutputChannel

func (i *CoreIO) GetScreenOutputChannel() chan *types.Screen

GetScreenOutputChannel returns the channel to push screen change events to the IO event loop
