Thor Animations, moving sprite
« on: June 11, 2012, 12:54:54 pm »
Hi, I' m using the animation example in Thor's source code (https://github.com/Bromeon/Thor/blob/master/examples/Animation.cpp) and, when I try to move the sprite, the animation automatically stops!

If I put at line 69 of the example this:
case sf::Keyboard::D:
                animator.playAnimation("drive", true);
                sprite.move(100, 0);
                break;

the sprite is moved but during the transiction the animation is stopped. Can anyone help me having an animated transiction?

Thanks Laurent for the move and the code editing! :D

I'm not quite sure how Thor handles the playAnimation function, but it could be that whenever you call it, the animation starts again from the beginning, thus if you 'start' the animation new everytime you move it, it will always show the first image of the animation i.e. it will look like it's not animated anymore.
You could start the animation when the event KeyPressed is emitted and stop it (or change it to the none moving animation) when the event KeyReleased gets emitted or you could use a boolean to check the state on your own.

Oh ok, I solved using a KeyReleased event! Thank you very much :)

No, wait! It didn't really solve my problem. I do this
bool right = true;
   
    // Clock
    sf::Time time = frameClock.getElapsedTime();
    float elapsed_time = time.asSeconds();
   
    switch (event.type)
        {
                case sf::Event::KeyPressed:
                    if (event.key.code == sf::Keyboard::Right)
                    {      
                if (right)
                {
                    animator.update(frameClock.restart());
                    animator.playAnimation("move_right", true);
                    right = false;
                }
                move(15 * elapsed_time, 0);
                    }
                break;
               
                case sf::Event::KeyReleased:
                    if (event.key.code == sf::Keyboard::Right)
                    {
                right = true;
                    }
                break;
        }
and the animation is stopped when the Sprite starts the transition. animator is a "thor::Animator<sf::Sprite, std::string>"

I fixed adding a "animator.stopAnimation ();" in each KeyReleased events
