General / how to display alternate images at each timestep

even when i put a constant value no movement and my x n y co-ordinates are

Code: [Select]

s.setPosX(width/2);s.setPosY(height/10);

but why would that be the problem, does the if statement call for the elapsed time consecutively until it matches the expression? or does it only call once?

it still aint moving my guess is the clock aint increasing so it aint reaching higher or equal 2 the timestep is there away i can keep track of the clock? so when it hits a certain time value it will excute the if statement

Code: [Select]

void SpaceInvadersDemo::init()
{
shipImage.LoadFromFile("myC++/images/asprite1.png");
shipImage2.LoadFromFile("myC++/images/asprite2.png");
shipSprite=sf::Sprite(shipImage), (shipImage2);
shipSprite.SetCenter(shipSprite.GetSize().x/2,shipSprite.GetSize().y/2);
s.setRadius(shipSprite.GetSize().x/2);
s.setPosX(width/2);s.setPosY(height/10);



}
void SpaceInvadersDemo::draw()
{
win.Clear(sf::Color(0,0,0));
shipSprite.SetPosition(s.getPosX(),s.getPosY());
win.Draw(shipSprite);
}
void SpaceInvadersDemo::getInput()
{
sf::Event Event;
        while (win.GetEvent(Event))
        {

            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                win.Close();
           //Escape key : exit
            if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
                win.Close();


        }
}
void SpaceInvadersDemo::update()
{
sf::Clock Clock;


if (Clock.GetElapsedTime()>=Timestep)
{

shipSprite.SetImage(shipImage2);
s.setPosX(s.getPosX()+moveIncrement);
Clock.Reset();


}

void SpaceInvadersDemo::play()
{
//the game loop
draw();//the offscreen buffer
getInput();//from the user
update();//integrate user input and any game movement which is automatic
}

thanks well i changed the code to

Code: [Select]

if (Clock.GetElapsedTime()>=Timestep)
{

shipSprite.SetImage(shipImage2);
s.setPosX(s.getPosX()+moveIncrement);
Clock.Reset();


}
and it still doesn't move does anybody know what the problem could be?

hey im tryin to make a program where the sprite has two images which are displayed alternatively at each timestep to give the impression of movement like space invaders


i did this  

Code: [Select]


    if (Clock.GetElapsedTime()==Timestep)
{

shipSprite=sf::Sprite(shipImage2);
s.setPosX(s.getPosX()+moveIncrement);

}


the timestep can be modified so a gamedesigner could change the speed of movement but it doesnt move at all
