Question about love.graphics.draws

[surtic]

What exactly is the connection between an image's centre (as set by setCenter, or the default centre), and the position of a partial image on the screen? I have a feeling that any partial bitmap is automatically centred, regardless of setCenter (and that there is no control over the centre of the partial image).

For example, I have this code:

Code: Select all

function load()
  image = love.graphics.newImage("square.png")
  image:setCentre(0, 0)
end

The image is a 100x100 pixels square. When I draw it like this:

Code: Select all

  love.graphics.draw(image, 100, 100)

it's doing what I'm asking it to do, but when I draw it like this:

Code: Select all

  love.graphics.draws(image, 100, 100, 0, 0, 100, 100)

the image is centred about (100, 100). I don't think I have any control over the centre point of the partial bitmap.

I thought that this could be a solution to the sprite-sheet problem (and the image-from-image suggestion), but having no control over the centre point means that I can't (for example) rotate a partial image about its real centre (unless it's exactly the bitmap's centre).

There should be an overload of love.graphics.draws which allows you to set the center within the partial image.

Thanks, I missed that one.
