// <--[command]
// @Name Walk
// @Syntax walk (<entity>|...) [<location>/stop] (speed:<#.#>) (auto_range) (radius:<#.#>) (lookat:<location>)
// @Required 1
// @Short Causes an entity or list of entities to walk to another location.
// @Group entity
//
// @Description
// Causes an entity or list of entities to walk to another location.
//
// Specify a destination location to walk to, or 'stop' to stop all walking.
//
// Optionally, specify a "speed:<#.#>" argument to control the speed of the NPCs.
//
// Optionally, specify "auto_range" to automatically set the path range for the walk instruction
// (if not specified, an NPC will not be able to walk to a location outside of its existing path range, by default 25 blocks).
// (Does not apply to non-NPC entities).
//
// Optionally, specify a list of entities to give them all the same walk instruction at the same time.
// If the list is of NPCs, optionally specify a "radius:<#.#>" argument to change the flocking radius.
// ('Radius' does not apply to non-NPC entities).
//
// Optionally, specify "lookat:<location>" to cause the NPCs to stare at a specific location while walking (as opposed to straight ahead).
// ('Radius' does not apply to non-NPC entities).
//
// @Tags
// <NPCTag.navigator.is_navigating>
// <NPCTag.navigator.speed>
// <NPCTag.navigator.range>
// <NPCTag.navigator.target_location>
//
// @Usage
// Use to make the NPC walk to an anchored position.
// - walk <npc> <npc.anchor[spot1]>
//
// @Usage
// Use to make the NPC walk to an anchored position that may be far away.
// - walk <npc> <npc.anchor[spot2]> auto_range
//
// @Usage
// Use to make the NPC walk to an anchored position while looking backwards.
// - walk <npc> <npc.anchor[spot3]> lookat:<npc.anchor[spot2]>
//
// @Usage
// Use to make a list of NPCs stored in a flag all move together, with a flocking radius based on the number of NPCs included.
// - walk <player.flag[squad]> radius:<player.flag[squad].size> <player.location>
