# Just type /walk [start/stop/to] [blocks|...] [radius] [speed]
# For example: /walk to grass 20 115 would make the NPC walk to grass,
# within 20 blocks, at 115% speed.
# Typing /walk again will make them do the same thing!
# You can also set some NPC flags to alter behavior
# walk_filter -- the blocks that the NPC will path to
# walk_radius -- the number of blocks in radius to search
# walk_speed -- the speed of the walking_task
# walk_duration -- the amount of time between walks when using /walk start
