LÖVE

I'm using Fixture:GetBoundingBox to get the position of rectangular fixtures, but the results of GetBoundingBox are very inaccurate to the actual position of its bounding box.

Here is the code I'm using to get fixture position: It returns this for an object located at 325, 825: Here is what it returns without v.body:GetWorldPoints(), with the same object: The obvious solution would be to just use v.body:GetPosition() instead of xx/yy, but I'm dealing with a situation where there are multiple fixtures under one body, and I need to draw all of those fixtures with love.graphics.draw (for its image support,) so it wouldn't work.

PS: Why isn't there just a Fixture:GetPosition() function???


Edit: I'm an idiot, I was multiplying instead of adding for the average equation.... Well, at least it's fixed now. (I could have sworn I had similarly weird results when just printing the coordinates of points returned by getBoundingBox() but whatever)

The obvious solution would be to use proper averaging formula, that being x = ( a + b ) / 2

Or if you want geometric mean instead of the arithmetic one (as shown above), then you can do x = math.sqrt(a*b) as well... as long as your coordinates aren't signed, or in other words, less than (or equal to) zero; the arithmetic one's probably what gets used most though and doesn't have this issue.
