in the snapshot 14w10b, i have noticed that the /particle command does not run properly. the command block says the command has been run successfully, but the particles do not show up around me or at any entity I specify. I'm using the command shown in the attached picture
The syntax for this command is
/particle <name> <x> <y> <z< <xd> <yd> <zd> <speed> [count] [selector]
the x, y, and z coordinates must be relative if you want the effect to be played relative to you.
change your command to /particle flame ~-2 ~-2 ~-2 2 2 2 5 100 @p
