Maybe something like this in reverse?
(Very old code so don't know how good it is)

Pgimeno obviously has a better understanding of what you want to accomplish. From your initial post I could see how you could accomplish what you asked using ox and oy and applying an offset to the x and y coordinates. For the life of me, I can't visualize exactly how you want the mechanics to work ...

Could it be so simple as changing ox and oy in (Probably off topic but 'Tanks' do rotate around their center.)

As posted before, you could always do the following. -- ***** Load/Save from Anywhere on Computer ***** -- To use, wrap 'filename' with 'mount'. -- for filename = 'D:/Scripts/Love/test.png' -- Load Example: love.graphics.newImage( mount( filename ) ) -- Save Example: id:encode('png', mount( filename...

Why is this always posted in two places - General and Libraries?

Gee!
Didn't know life was really this complex.
For those who don't know what they are talking about (like me), this is an example of what they think is very inefficient (and probably off topic).
Be interest in seeing what they come up with.

Don't know about best but will give you a starting point.

For just playing around on windows I use the simple mount function to get around Love's file restrictions. mount = function( name ) local ffi = require( 'ffi' ) local lv = ffi.load( 'love' ) ffi.cdef[[ int PHYSFS_mount(const char *newDir, const char *mountPoint, int appendToPath); ]]; ffi.cdef[[ int...

I'm sure pgimeno will say I'm off track again but wouldn't this be close enough - a simple semi-transparent rectangle?

Sounds like over kill to me.
I like: If delay is set to something like 6, you get a nice smooth movement to the mouse coords (mx,my).
