Hi,
I am trying to test this timer movement and I just don't understand why the rectanglee is not moving right and down. Here is a simple test. Using GLFW.

#include <GL/glfw.h>
#include <stdlib.h>

void Init()
{
    //! Create the viewport and projection
    glClearColor(0.4f,0.4f,0.4f,1.0f);
    glViewport(0, 0, 800, 600);
    glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    glOrtho(0,800, 600,0,0,5);
    glMatrixMode(GL_MODELVIEW);
    glLoadIdentity();
}
void CreateRect(int x, int y)
{
    glBegin(GL_QUADS);
        glVertex3f(x, y-32, 0);
        glVertex3f(x+32, y-32, 0);
        glVertex3f(x+32, y, 0);
        glVertex3f(x, y, 0);
    glEnd();
}

int main( void )
{
    //! Initialize GLFW
    if( !glfwInit() )
    {
        exit( EXIT_FAILURE );
    }
    //! Open an OpenGL window
    glfwOpenWindowHint( GLFW_WINDOW_NO_RESIZE, GL_TRUE );
    if( !glfwOpenWindow( 800,600, 0,0,0,0,0,0, GLFW_WINDOW ) )
    {
        glfwTerminate();
        exit( EXIT_FAILURE );
    }

    Init();

    int X_Pos = 256;
    int Y_Pos = 256;
    double StartTime = glfwGetTime();
    int MOVEMENT_SPEED = 2;
    int running = GL_TRUE;
    //! Main loop
    while( running )
    {
        //! OpenGL rendering goes here...
        //! OpenGL rendering goes here...
        glClear( GL_COLOR_BUFFER_BIT );
        //! Swap front and back rendering buffers
        CreateRect(X_Pos, Y_Pos);

        glfwSwapBuffers();

        //! Timer movement
        double NewTime = glfwGetTime();
        const float ElapsedTime = (float)(NewTime - StartTime) / 1000.f;
        StartTime = NewTime;

        int New_X = X_Pos;
        int New_Y = Y_Pos;
        //!Up
        if(glfwGetKey('W'))
        {
            New_Y -= MOVEMENT_SPEED * ElapsedTime;
        }
        //!Down - not moving
        if(glfwGetKey('S'))
        {
            New_Y += MOVEMENT_SPEED * ElapsedTime;
        }
        //!Left
        if(glfwGetKey('A'))
        {
            New_X -= MOVEMENT_SPEED * ElapsedTime;
        }
        //!Right - not moving
        if(glfwGetKey('D'))
        {
            New_X += MOVEMENT_SPEED * ElapsedTime;
        }

        X_Pos = New_X;
        Y_Pos = New_Y;

        //! Check if ESC key was pressed or window was closed
        running = !glfwGetKey( GLFW_KEY_ESC ) && glfwGetWindowParam( GLFW_OPENED );
    }
    //! Close window and terminate GLFW
    glfwTerminate();
    //! Exit program
    exit( EXIT_SUCCESS );
}

Thanks in advance,
Regards.
