Graphics / [SOLVED]SFML 2 - Problem with Rotation and Move

« on: June 10, 2012, 06:01:28 am »

SOLVED

Hi I have one problem and I have no idea how to solve it

When I rotate my sprite I want to move in direction where the sprite is pointed at.
Here is the code responsible for rotating and moving the sprite.

float char_dir = main_char.getRotation();

if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up) || sf::Keyboard::isKeyPressed(sf::Keyboard::W))
{
        main_char.move(cos(char_dir * M_PI / 180) * 3, sin(main_char.getRotation() * M_PI / 180) * -3);
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down) || sf::Keyboard::isKeyPressed(sf::Keyboard::S))
{
        main_char.move(cos(char_dir * M_PI / 180) * -3, sin(main_char.getRotation()* M_PI / 180) * 3);
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right) || sf::Keyboard::isKeyPressed(sf::Keyboard::D))
{
        main_char.rotate(2.0f);
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left) || sf::Keyboard::isKeyPressed(sf::Keyboard::A))
{
        main_char.rotate(-2.0f);
}

It's not working properly.
I have no idea on how to move the character backward.
Moving forward is almost working properly. Almost

Also I did this because I read that it's important but it's still not working.

main_char.setOrigin(main_char_tex.getSize().x / 2, main_char_tex.getSize().y / 2);

Please help me.
Thanks.
