System / Problems with sf::Thread

Look at this code and you'll maybe get my problem:

Code: [Select]

#include <SFML/Graphics.hpp>
#include "AniSprite.h"

using namespace std;

int main()
{
    sf::RenderWindow App(sf::VideoMode(800, 600), "Test");

    sf::Image Image;
    if(!Image.LoadFromFile("character.png"))
    {
        return EXIT_FAILURE;
    }

    AniSprite Sprite(Image, 47, 64);
    Sprite.SetLoopSpeed(10);
    Sprite.SetPosition(0, 400);

    int Direction = 1;

    while(App.IsOpened())
    {
        sf::Event Event;
        while(App.GetEvent(Event))
        {
            if (Event.Type == sf::Event::Closed)
            {
                App.Close();
            }
        }

        float ElapsedTime = App.GetFrameTime();

        if (App.GetInput().IsKeyDown(sf::Key::Left))
        {
            Sprite.Play(12, 0);
            Sprite.Move(-100 * ElapsedTime, 0);
            Direction = 0;
        }
        else if(App.GetInput().IsKeyDown(sf::Key::Right))
        {
            Sprite.Play(4, 8);
            Sprite.Move(100 * ElapsedTime, 0);
            Direction = 1;
        }
        else if(Direction == 1)
        {
            Sprite.Play(4, 5);
        }
        else
        {
            Sprite.Play(12, 13);
        }

        App.Clear();

        Sprite.Update();

        App.Draw(Sprite);

        App.Display();
    }
    return EXIT_SUCCESS;
}
The animation won't update when the user is moving it.

System / Problems with sf::Thread

I've tried using Play() and Update() in the main loop, but when I press the key the animation stops. I thought it was because it can't move and update the animation at the same time. :?

System / Problems with sf::Thread

Hi!
My name is Marcus and I've just started learning SFML. I've recently run in to a small problem that needs to be solved. I'm using AniSprite (http://www.sfml-dev.org/wiki/en/sources/anisprite) to do a little program with an animated character that can move around a bit. However it's not the graphics part that I have a problem with. When a specified key is pressed I want him to move in a direction and do the animation at the same time. Therefore I thought I could use the sf::Thread-function, but (sadly) it's not working like I want it to work.
Here's the code for main.cpp:

Code: [Select]

#include <SFML/Graphics.hpp>
#include "AniSprite.h"

using namespace std;

void Left(AniSprite Sprite)
{
    Sprite.Play(4, 8);
    Sprite.Update();
}

void Right(AniSprite Sprite)
{
    Sprite.Play(12, 0);
    Sprite.Update();
}

int main()
{
    sf::RenderWindow App(sf::VideoMode(1440, 900), "Test");

    sf::Image Image;
    if(!Image.LoadFromFile("character.png"))
    {
        return EXIT_FAILURE;
    }

    AniSprite Sprite(Image, 47, 64);
    Sprite.SetLoopSpeed(10);
    Sprite.SetPosition(0, 400);

    [b]sf::Thread Thread1(Left(Sprite));[/b]
    [b]sf::Thread Thread2(Right(Sprite));[/b]

    int Direction = 1;

    while(App.IsOpened())
    {
        sf::Event Event;
        while(App.GetEvent(Event))
        {
            if (Event.Type == sf::Event::Closed)
            {
                App.Close();
            }
        }

        float ElapsedTime = App.GetFrameTime();

        if (App.GetInput().IsKeyDown(sf::Key::Left))
        {
            Thread1.Launch();
            Sprite.Move(-100 * ElapsedTime, 0);
            Direction = 1;
        }
        else if(App.GetInput().IsKeyDown(sf::Key::Right))
        {
            Thread2.Launch();
            Sprite.Move(100 * ElapsedTime, 0);
            Direction = 0;
        }
        else if(Direction == 1)
        {
            Sprite.Play(4, 5);
        }
        else
        {
            Sprite.Play(12, 13);
        }

        App.Clear();

        Sprite.Update();

        App.Draw(Sprite);

        App.Display();
    }
    return EXIT_SUCCESS;
}
Error code (line 32 and 33):

Code: [Select]

error: invalid use of void expression
I've tried different parameters in the Left- and Right-functions like:

Code: [Select]

void Left(AniSprite Sprite(const sf::Image& Img, int frameW, int frameH))
But that'll just end me up with more error codes.
I'll appreciate all help I can get.
