Hello ...i'm french, sorry but nobody answers for 2 weeks on french forum.
I make a tilemap with the SFML Tutorial
https://www.sfml-dev.org/tutorials/2.5/graphics-vertex-array.php. (version française)
I want to make an isometric tileMAP. The code work for me, but when i move the map there are an ugly result.
In game we can move in heigt directions.
The idle, left and right make a good result.
The others directions (up, down, down+left, up+right ...) change the color of the border of tiles in black to grey.
I sink it's a visual effect and not a color change.
I try to change VerticalSyncEnabled , setFramerateLimit , sf::Time timeInterval = sf::milliseconds(20);, but no good result.
the code :
//systeme windows
#include <windows.h>
#include <iostream>
#include <string>
#include <ctime>
#include <cstdlib>
//SFML
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
int const SCREEN_X = GetSystemMetrics(SM_CXSCREEN);
int const SCREEN_Y = GetSystemMetrics(SM_CYSCREEN);
int const SCREEN_X_MIDDLE = SCREEN_X / 2;
int const SCREEN_Y_MIDDLE = SCREEN_Y / 2;
int const UP = 4, UP_RIGHT = 3, RIGHT = 2, DOWN_RIGHT = 1, DOWN = 0,DOWN_LEFT = 7,LEFT = 6,UP_LEFT = 5;
void maj_direction(bool up,bool right, bool down, bool left, int& xMove , int& yMove)
{
int direction = -1;
if ( up && !right && !down && !left )
{direction = UP; xMove = 0; yMove = -1;}
if ( up && right && !down && !left )
{direction = UP_RIGHT; xMove = 1; yMove = -1;}
if (!up && right && !down && !left )

I join the tile and a test with full map texture sprite.
S.O.S, Can you help me ?
