Joysticks[].ID will have the number of the physical input device mapped to that controller (this value range between 0 and the total number of connected physical devices). The mapping of a certain physical device to joystate[].joy is initially done by Initialize(), but for the configuration we can remap that, like in ConfigBox::ChangeJoystick(). The joyinfo[] array holds the physical gamepad info for a certain physical device. It's therefore used as joyinfo[PadMapping[controller].ID] if we want to get the joyinfo for a certain joystick. ////////////////////////*/ ////////////////////////////////////////////////////////////////////////////////////////// // Include // ŻŻŻŻŻŻŻŻŻ #include "nJoy.h" // Declare config window so that we can write debugging info to it from functions in this file #if defined(HAVE_WX) && HAVE_WX ConfigBox* m_frame; #endif ///////////////////////// ////////////////////////////////////////////////////////////////////////////////////////// // Variables // ŻŻŻŻŻŻŻŻŻ // Rumble in windows #define _CONTROLLER_STATE_H // Avoid certain declarations in nJoy.h FILE *pFile; HINSTANCE nJoy_hInst = NULL; CONTROLLER_INFO *joyinfo = 0; CONTROLLER_STATE joystate[4]; CONTROLLER_MAPPING PadMapping[4]; bool emulator_running = FALSE; HWND m_hWnd; // Handle to window // TODO: fix this dirty hack to stop missing symbols void __Log(int log, const char *format, ...) {} void __Logv(int log, int v, const char *format, ...) {} // Rumble #ifdef _WIN32 #elif defined(__linux__) extern int fd; #endif ////////////////////////////////////////////////////////////////////////////////////////// // wxWidgets // ŻŻŻŻŻŻŻŻŻ #if defined(HAVE_WX) && HAVE_WX class wxDLLApp : public wxApp { bool OnInit() { return true; } }; IMPLEMENT_APP_NO_MAIN(wxDLLApp) WXDLLIMPEXP_BASE void wxSetInstance(HINSTANCE hInst); #endif ////////////////////////////////////////////////////////////////////////////////////////// // DllMain // ŻŻŻŻŻŻŻ #ifdef _WIN32 BOOL APIENTRY DllMain( HINSTANCE hinstDLL, // DLL module handle DWORD dwReason, // reason called LPVOID lpvReserved) // reserved { switch (dwReason) { case DLL_PROCESS_ATTACH: { //use wxInitialize() if you don't want GUI instead of the following 12 lines wxSetInstance((HINSTANCE)hinstDLL); int argc = 0; char **argv = NULL; wxEntryStart(argc, argv); if (!wxTheApp || !wxTheApp->CallOnInit() ) return FALSE; } break; case DLL_PROCESS_DETACH: wxEntryCleanup(); //use wxUninitialize() if you don't want GUI break; default: break; } nJoy_hInst = hinstDLL; return TRUE; } #endif ////////////////////////////////////////////////////////////////////////////////////////// // Input Plugin Functions (from spec's) // ŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻ // Get properties of plugin // ŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻ void GetDllInfo(PLUGIN_INFO* _PluginInfo) { _PluginInfo->Version = 0x0100; _PluginInfo->Type = PLUGIN_TYPE_PAD; #ifdef DEBUGFAST sprintf(_PluginInfo->Name, "nJoy v"INPUT_VERSION" (DebugFast) by Falcon4ever"); #else #ifndef _DEBUG sprintf(_PluginInfo->Name, "nJoy v"INPUT_VERSION " by Falcon4ever"); #else sprintf(_PluginInfo->Name, "nJoy v"INPUT_VERSION" (Debug) by Falcon4ever"); #endif #endif } void SetDllGlobals(PLUGIN_GLOBALS* _pPluginGlobals) { } // Call config dialog // ŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻ void DllConfig(HWND _hParent) { #ifdef _WIN32 // Start the pads so we can use them in the configuration and advanced controls if(!emulator_running) { SPADInitialize _PADInitialize; _PADInitialize.hWnd = NULL; _PADInitialize.pLog = NULL; Initialize((void*)&_PADInitialize); emulator_running = false; // Set it back to false } g_Config.Load(); // Load settings // We don't need a parent for this wxDialog //wxWindow win; //win.SetHWND(_hParent); //ConfigBox frame(&win); //win.SetHWND(0); m_frame = new ConfigBox(NULL); m_frame->ShowModal(); #else if (SDL_Init(SDL_INIT_JOYSTICK ) < 0) { printf("Could not initialize SDL!
