Hi,
I start this pool because I would like to know how you work with 2dtoolkit in unity and why. Do you setup your cam to let a unit/meter be a pixel? Or do you directly work with units (2dtoolkit default is 20 pixels=1 unit). I found more suitable to use pixels because it is more understable to me. Things like positioning something at this x,y pos in pixels is much better than converting x,y to units based on 2dtoolkit configuration. What do you use? Have you found any problem working with units?
On the other hand has anybody found any problem working with the physic engine in pixels?
