I know this isn't summon or setblock, but I couldn't find another thread for it. I'm trying to use the new 1.8 parameters for a cubic testfor area but it doesn't seem to work. This is the command I'm trying to use:
testfor @p[x=-461,y=60,z=1303,dx=-463,dy=61,dz=1305]
the labels are there because the game seems to assume the number directly following x, y, and z is the radius and ignores the rest. Is there something that I am doing wrong or is it just a bug in the snapshot? I've tried changing the coordinates to include much larger areas to no avail.
