Add center() method for Sprite
« on: September 14, 2016, 10:17:24 pm »
Hello. Very often I need to center sprite relative to some position. So I have to do something like
sprite.setPosition(newX-sprite.getGlobalBounds().width/2, newY-sprite.getGlobalBounds().height/2)

but it will be very useful to do something this:
sprite.center(newX, newY);
 

Thanks.

Probably best not to use global bounds to move a position; it will move it every time this is called.

What's wrong with using this:
sprite.setOrigin(sprite.getLocalBounds().width / 2.f, sprite.getLocalBounds().height / 2.f);
just once and then every time you set its position, it'll be centred.

If you use Plinth (I do all the time!), you can use its SFML Anchors. For example:
sprite.setOrigin(pl::Anchor::Local::getCenter(sprite));
