Collision Detection Problems and freezes with sprites etc

[KasHKoW]

Hi, I've developed somewhat a basic little pong like ball that has to stay within certain boundaries. When dealing with a sf::shape, it doesn't have any type of bugs or errors. While using the same code as the sf::shape, if I switch it to sf::sprite with an image acting as the ball, it will freeze and be very buggy going through the boundaries set.

I'm wondering why is this? Is sf::sprite more intense and need to be implemented some other way. Should I add extra catching boundaries or possibly(just thought of now) have a exception like clause that will redraw and reimplement the ball on messing up exactly where it was last within the boundaries??

It might help to show your code.

Remember to set the center of the sprite, such as: Ball.setCenter(Ball.getSize() / 2.f)

That might be why it appears buggy, since by default the center of the sprite is the top left corner.

That's just an idea

That actually might be why. I never set the center of any sprites. I just sf::Sprite::SetPosition().

Could you give me a more in depth explanation of why this is needed? I really want to understand this. Idk I probably took 30 seconds to think about why this didn't work and my answers were completely different than sf::Sprite::SetCenter().

Also possibly how Sprites are loaded and about them etc.

Thanks

Hey, I was actually thinking... lol thinking.... you say that I need to use sf::Sprite::SetCenter... Why would that matter dependent on if it was sf::Shape or sf::Sprite. Shouldn't they be the same and it be totally independent on those two classes. As in since the code worked for sf::Shape then why would sf::Sprite not work and need sf::Sprite::SetCenter()?? Yup just checked... sf::Shape has a sf::Shape::SetCenter() function as well.
