Salut a tous
J'aimerais vous faire partager un bout de code donc je ne peu presque plus me passer.
Une petite fonction à intégrer au début de votre programme qui permet de configurer quelque paramètre d'affichage.
Et comme un dessin (enfin un screen pour nous) vaut souvent mieux qu'un discours :
C'est quand meme plus sympa que des messages dans une console.
Un des avantages, c'est qu'il sauvegarde a chaque fois les dernier paramètre d'affichage utilisé.
Bon, on va commencer par le fichier main.cpp
#include <irrlicht.h> #include "menu.h" using namespace irr; using namespace core; using namespace scene; using namespace video; using namespace gui; int main() { bool runApps = false; int l_windows = 640; int h_windows = 480; bool fullscreen = false; bool shadows = false; bool vsync = false; E_DRIVER_TYPE driverType = EDT_DIRECT3D9; //on envoie a notre fonction les parametre d'affichage, cette fonction revoie "true" si on clic sur start runApps = startMenu(&l_windows, &h_windows, &fullscreen, &shadows, &vsync, &driverType); if(runApps) { //on créer nore device avec les parametre que l'on a definie dans notre fonction IrrlichtDevice *device = createDevice(driverType, core::dimension2d<s32>(l_windows,h_windows),32,fullscreen,shadows,vsync); IVideoDriver* driver = device->getVideoDriver (); while (device->run()) { driver->beginScene(true, true, video::SColor(0,200,200,200)); driver->endScene (); } } }
On créer un fichier "menu.h" :
Puis le fichier "menu.cpp" :
#include <irrlicht.h> #include <stdio.h> #include <string.h> #include <string> #include <iostream> #include "menu.h" using namespace irr; using namespace core; using namespace scene; using namespace video; using namespace gui; // Declare a structure to hold some context for the event receiver so that it // has it available inside its OnEvent() method. struct SAppContext { IrrlichtDevice *device; IGUIListBox *boxResolution; IGUIListBox *boxRender; }; // Define some values that we'll use to identify individual gui controls. enum { GUI_ID_QUIT_BUTTON = 101, GUI_ID_START_BUTTON, GUI_ID_DRIVER_SELECT, GUI_ID_RESOLUTION_SELECT, GUI_ID_FULLSCREEN, GUI_ID_SHADOWS, GUI_ID_VSYNC, }; class menuEventReceiver : public IEventReceiver { public: //constructeur menuEventReceiver(SAppContext & context) : Context(context) { selectRender = 0; selectResolution = 1; fullscreen = false; shadows = false; vsync = false; runApps = false; } s32 selectRender; s32 selectResolution; bool fullscreen; bool shadows; bool vsync; bool runApps; virtual bool OnEvent(const SEvent& event) { if (event.EventType == EET_GUI_EVENT) { s32 id = event.GUIEvent.Caller->getID(); IGUIEnvironment* env = Context.device->getGUIEnvironment(); switch(id) { case GUI_ID_QUIT_BUTTON: if(event.GUIEvent.EventType == EGET_BUTTON_CLICKED) { Context.device->closeDevice(); } return true; case GUI_ID_START_BUTTON: if(event.GUIEvent.EventType == EGET_BUTTON_CLICKED) { runApps = true; Context.device->closeDevice(); } return true; case GUI_ID_DRIVER_SELECT: if (event.GUIEvent.EventType == gui::EGET_LISTBOX_CHANGED || event.GUIEvent.EventType == gui::EGET_LISTBOX_SELECTED_AGAIN) { selectRender = ((gui::IGUIListBox*)event.GUIEvent.Caller)->getSelected(); } return true; case GUI_ID_RESOLUTION_SELECT: if (event.GUIEvent.EventType == gui::EGET_LISTBOX_CHANGED || event.GUIEvent.EventType == gui::EGET_LISTBOX_SELECTED_AGAIN) { selectResolution = ((gui::IGUIListBox*)event.GUIEvent.Caller)->getSelected();

Voilou. Je ne vous fait pas trop de commentaire sur ce code, il est pas très complexe.
Ceux qui le veulent peuvent télécharger le projet avec le code ici : Select_parametre_download
Merci pour le code nabouill c'est relativement utile 
d'autant que c'est facilement isérable dans les menus de nos ptits jeux qu'on aime
