/testfor in minecraft 14w11b (snapshot of 1.8)

I can't test for people's locations using @a[x=-563,y=4,z=23]. Instead, the redstone comparator will just turn on even if no one is at -563,4,23.

Best Answer

Try specifying a maximum search radius, for example:

@a[x=-563,y=4,z=23,r=1]

Note that you can use this shortcut:

@a[-563,4,23,1]
