// <--[command]
// @Name Attack
// @Syntax attack (<entity>|...) (target:<entity>/cancel)
// @Required 0
// @Short Makes an entity, or list of entities, attack a target.
// @Group entity
//
// @Description
// By itself, the 'attack' command will act as an NPC command in the sense that an attached
// NPC will attack the attached player, or specified target. It can also accept a specified entity,
// or list of entities, to fulfill the command, just specify a 'fetchable' entity object. This includes
// player objects (dPlayers) and NPC objects (dNPCs). To specify the target, prefix the entity
// object with 'target:' or 't:'.
//
// To cancel an attack, use the 'cancel' argument instead of specifying a target.
//
// @Tags
// <n@npc.navigator.is_fighting>
// <n@npc.navigator.attack_strategy>
// <n@npc.navigator.target_entity>
//
// @Usage
// Use to make an NPC attack a player in an interact script.
// - attack
//
// @Usage
// Use to make an NPC attack a nearby entity.
// - attack target:<npc.location.find.living_entities.within[10].random>
//
// @Usage
// Use to make a specific entity attack an entity, including players or npcs.
// - attack <player.location.find.living_entities.within[10].random> target:<player>
//
// @Usage
// Use to stop an attack
// - attack n@Herobrine stop
