Input handling system

1 post in this topic


I know there has been qute a few topics like this but none of them turned out to be useful for my case. I'm in the middle of the development of my simple engine but I'm struggling with creating a fast reliable input manager. To illustrate my case let me show you my choose of design.

Main Entry -> Instantiates a SystemClass that encapsulates the following factories:[list]
[*]GraphicsManager - Handles Direct3D related code.
[*]Demo Projects - Derives from DirectXManager
To handle user input I'm using the WINAPI Message handler like:
[source lang="cpp"]LRESULT CALLBACK SystemClass::MsgHandler(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
switch (uMsg)
case WM_KEYUP:



m_GraphicsHandler->OnMouseMove(wParam, GET_X_LPARAM(lParam), GET_Y_LPARAM(lParam));
You can see the basic idea. The GraphicsHandler has the necessary functions which handles the user Events. My last attempt was something like this:

[source lang="cpp"]class InputFactory
static InputFactory* Instance;
static InputFactory* GetInstance(void);
IHandler* CreateHandler(HandlerType hType = HandlerType::MouseHandler);


class IHandler
friend class InputFactory;
struct Event
EventType eType;
void (*Handler)(MappedKey mKey, State* hState);
std::queue<Event> Interactions;
void RegisterEvent(EventType eType = EventType::MouseEvent, ...);
void ProcessEvent(void);
I think you get the main idea. My problem with this approach is that it's way too complex and hard to add new features. Not to mention that to modify the keybindings it's a nightmare. I found an article about inputmanager here on gamedev.net but I can't apply it to my case. Edited by Wrath87

Assuming you're talking about [url=http://www.gamedev.net/blog/355/entry-2250186-designing-a-robust-input-handling-system-for-games/]this article[/url], why do you think you can't apply it to your situation?
