My first experiments with mouse detection and image rotation

I think I've been doing decent here, but there's obviously something wrong. I wanted to make the rotation centered at the middle of the picture, not the ship.x point. However it doesn't seem like using the (ship.x+imgs.ship:getWidth())/2 is getting me that...
Any help guys?

Check out the offset arguments of
love.graphics.draw

That's what I was thinking about...What exactly ARE the offsets? I noticed them in other people's sources but I don't really know what they are.

They move the ship image left and up by their amount, and the ship image rotation center by their amount right and down. Example, to rotate an image around its center:
Code: Select all
love.graphics.draw(ship.image, ship.x, ship.y, ship.rotation, 1, 1, ship.image:getWidth()/2, ship.image:getHeight()/2)
