The angle already is defined as A-D-H and an ideal hbond would have angle 0.

Betreff: vmd-l: hydrogen bond criteria
Hello VMD users,
I found something a bit odd using the hbonds plugin. According to the
plugin, the criteria for the formation of a hydrogen bond are the distance
between the donor D and the acceptor A and the angle D-H-A. The cut-off
angle is by default 20 degrees, which means that D and A are too close to
each other. In my opinion, it should be the angle H-D-A with a cut-off angle
of 20 degrees. What do you think ?
Thank you in advance,
Alex
