{
Convexshape shape(4);
Shape.setfillcolor(0);
shape.setpoint( 0 ,Vector2f(x1-w1,y1));
shape.setpoint(1, Vector2f(x2-w2,y2));
shape.setpoint(2,Vector2f(x2+w2,y2));
shape.setpoint(3,vector2f(x1+w1,y2);
w.draw(shape);
int main()
{
Renderwindow app(Video mode(width,height), " outrun racing!");
app.();

app.setFramerateLimit(60);
While(app.isopen());
{
Event e;
While(app.pollevent(e));
{
