bonsoir,
dans mon programme opengl c++, j'ai une voiture qui roule sur une route mais alors je la fais rouler d'un pas de 0.1 et au lieu qu'il roule d'une facon continu elle roule discret comme si elle fait des pas (surement c'est probleme de memoire ) puis elle reste de bouger apres un certain nombre de pas meme si la boucle est pour l'infini
je sais pas pourquoi
voila le code : je souhaite que vous me detectez le probleme : 
#include "stdafx.h"
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
#include <math.h>
#include <Windows.h>
#include <GL/glut.h>
#include "drawing_functions.h"
#include "SOIL.h"
//#include "glm.h"
//#include "drawmodel.h"
//#include "glm.c"


/* l'heure systeme

SYSTEMTIME Time;
    
    GetLocalTime(&Time);
    
    printf("Nous sommes le : %02d/%02d/%04d.\n",
    Time.wDay, Time.wMonth, Time.wYear);

    printf("Et il est : %02dh %02dmn %02ds %03dms.\n",
    Time.wHour, Time.wMinute, Time.wSecond, Time.wMilliseconds);

Bonjour.
Ton pseudo ne donne pas vraiment envie de répondre mais il y'a un effort de fait et une vrai question posée même si le français n'est pas maitrisé.
Pour le déplacement des objets, il y'a des règles à respecter:
-Pour que le déplacement soit fluide, l'objet doit être déplacé à chaque images (évident pour certains).
-Le déplacement est calculé en tenant compte du FPS (pour que la vitesse soit la même sur tout les ordinateurs, lents ou rapides). Le calcul de base peut ressembler à: Déplacement/Frame = Vitesse/FPS.
Avec ce calcul, plus le PC sera rapide, plus le déplacement sera fluide, mais la distance/seconde sera pareil chez tout le monde
