Description: Citizens NPCs that attack monsters and can be killed.

Sentry is a Citizens 2.0 character trait that gives NPCs the ability to:

• Attack monsters, players, and groups automatically.
• Kill, and be killed by, players, monsters, and the environment.
• Guard locations, paths, players, or other NPCs.
• Use ranged or melee weapons.
• Be configured with stats such as strength, armor, speed, and night vision.
• Work with Denizen to create NPCs that run scripts upon death.

Updates

Sentry does not require Towny, but if you use it you can add a "TOWN:TownName" target to your sentries and they will target players from that town.

• Added in a hack to periodically remove bugged arrows when no players are around. Hopefully this is temporary.

v. 0.7.9.2 beta 8/12/2012

• Fix Sentries not checking GROUP targets.
• Checks for world groups first then global groups if no world groups found. Should be compatible with more perms systems.
• Sentries will forget their attackers if they heal back to full health. (This only applies to Scripted Deaths)

v. 0.7.9.1 beta 8/12/2012

• Fix for doppelgangers on /citizens reload
• Sentries set to not drop equipment also don't drop EXP.

• Lots of bugfixes to speed, pathing, guarding, damage, arrow physics.

v. 0.7.4.5 beta 8/7/2012

• Bugfixes all over.
• Bodyguards will no longer take damage from other bodyguards guarding the same target. (unless friendly fire is on... and if FF and Retaliate are both on.. they will attack and kill each other (merc's have a temper.))
• Bodyguards are more persistent. If you get separated from your guard move within its Range and it should start following you again. Remember where you parked your bodyguard!
• Known bugs: Sentries sometimes take multiple hits.. note sure if Sentry or Core C2 problem. Bodyguards may lose their target.

How to Use

Installation

• Ensure Citizens2 and Vault are installed
• Download file. See top of page
• Place Sentry.jar in your Plugins folder.
• Start Server

Permissions

See Sentry Permissions

Commands

All /sentry commands normally require a selected NPC. use /npc select # to do this.

Alternatively you may use /sentry # [command] to send a sentry command to a specified sentry without selecting it. # is the Sentry's npc id.

Example: /sentry 3 add target entity:monster will add the monsters target to sentry with npcID 3.

Creation

To create a sentry, use:

/npc create 'NPC Name'

/trait sentry

or

/npc create 'NPC Name' --trait sentry

To place your sentry use:

/npc path

And use the Waypoints editor to give your Sentry a place to stand, or a path to walk.

To equip you Sentry with weapons and armor use:

/npc equip

And right click with the desired weapon or armor. See the #Combat section for a discussion of weapons and armor

If you would like the Sentry to respawn in a different place from where it was created. Move it using

/npc tphere

And then call

/sentry spawn

Targets

Sentries are on the constant lookout for targets. Targets can be monsters, passive mobs, players, or player groups.

Sentries look at all the possible targets they can see in their range, and select the closest one.

A target cannot be seen if it is out of line-of-sight or if it is too dark for the Sentry's nightvision

Melee Sentries will chase targets until the target is dead or has gotten out of range.

Ranged Sentries do not follow targets, but will stay on their spot/path and fire at the target until it is dead or out of projectile range.

Note that detection range is not the same as projectile range. Projectiles have a fixed range depending on their type. Archers, for example, have a range of about 50 blocks on flat ground. Elevated sentries can hit targets farther away. Sentries that throw things have shorter range.

To add a target:

/sentry target add [target]

[target] can be entity:Name, entity:monster, entity:player, group:Name, or player:Name

If you use Towny you can also use town:townname

entity:monster is a shortcut to make the Sentry attack all hostile mobs.

entity:player is a shortcut to make the Sentry attack all players.

player:SentryName can be used to attack another Sentry.

Example: /sentry target add player:Notch or /sentry target add entity:creeper

To remove a target:

/sentry target remove [target]

To view the target list:

/sentry target list

To clear the target list:

/sentry target clear

Guarding

Sentries can be set as Lookouts or Bodyguards. Lookouts guard a location or path (set with /npc path), Bodyguards follow around an assigned living target (player or NPC).

If a bodyguard is set to Retaliate, it will attack anything that attacks the assigned guard target or itself.

If a bodyguard is set for Friendly Fire it can accidentally damage and be damaged by its guard target.

To set a Sentry as a bodyguard for a target NPC or Player:

/sentry guard [Name]

Note: The target must be within the Sentry's Range when the target is set.

To set the Sentry back to the default Lookout mode:

/sentry guard

Stats

Stats are Sentry settings that take a value and affect its performance.

To set a stat use:

/sentry [stat] [value]

Example: /sentry armor 5

To view the current value of a stat and get help:

/sentry [stat]

Example: /sentry range

To view all the Sentry's stats, as well as current target, status, and guard target, use:

/sentry info

Stat	Default Value	Value Range	Notes
health	20	1-20	The number of hit points the Sentry has. Normal players have 20.
armor	0	0-10	This value is subtracted from all incoming damage. An armor of 10 makes the Sentry very hard to hurt. Armor items equipped on the Sentry have no effect on combat.
strength	1	0-10	This is the damage the sentry does with each hit, regardless of weapon (or object) held.
range	10	1-100	This is the detection range for the Sentry. High values may affect server performance. This is not the same as the projectile range, which is dictated by projectile type and the Sentry's elevation relative to the target.
speed	1.0	0.0-1.5	This is the speed at which a sentry will move while pursuing a target. To set the normal path speed use /npc speed.
attackrate	2.0	0.0-30.0	This is the number of seconds between projectile shots and has no effect if the Sentry uses a melee weapon. The minimum internal rate is 0.5 (twice a second).
healrate	0.0	0.0-300.0	This is the number of seconds between heals of 1 point. The minimum internal rate is 0.5 (twice a second). Set to 0 to turn off healing.
nightvision	16	0-16	This is how well the Sentry can see potential targets in the dark. A value of 16 means the sentry can see perfectly all the time. A value of 12 means a target is invisible below light level 4 (16-12) . A value of 6 means a target is invisible below light level 10 (16-6), etc. If the target is a Player and that player is sneaking, its effective light light level is cut in half, making it harder for the sentry to detect.
respawn	10	-1-300	When the sentry dies, this is the number of seconds after which it will respawn. If this value is set to -1 the Sentry will not respawn and be permanently destroyed.

Options

Options are sentry settings that can be toggled on and off and affect its behavior.

/sentry [option]

Example: /sentry invincible

To view all the Sentry's stats, options, current target, status, and guard target, use:

/sentry info

Option	Default Value	Notes
drops	False	If this is True the Sentry will drop his equipment on death.
invincible	False	If this is True the Sentry will not take any damage, be knocked back, or show a 'hurt' flash.
retaliate	True	If this is True, the Sentry will attack to any living thing that attacks it. If the Sentry is acting as a bodyguard, it will also attack any living thing that attacks its guard target.
criticals	True	If this is true the Sentry will take critical hits and misses. If False, the normal damage is always applied.
friendlyfire	False	If this is True the sentry can be damaged by and cause damage to any living thing. If this is False, the Sentry will not damage or receive damage from its guard target or any other Sentries guarding that target. Using friendlyfire and retaliate at the same time is highly not recommended, although hilarious.

Combat

Sentries can engage in rewarding combat with players, monsters, and even each other!

Equipment

A Sentry should be equipped with a weapon to make it look right, but any hand held item can be used.

Sentries equipped with a Bow, Blaze Rod, Egg, or Snowball become Ranged sentries. and will fire projectiles at the target:

• Archers have a range of about 50 blocks on flat ground, more when elevated.

• Bombadiers have a range of about half that of Archers.

• Pyromancers have.. pretty much an unlimited range, be very careful with pyromancers.

All armor and weapons are cosmetic from a combat standpoint. The amount of damage the Sentry gives and takes is determined by its strength and armor.

Dealing Damage

The damage dealt by a Sentry when attacking a target is equal to the sentry's strength.

Typically players have 20 health. By default a Sentry has 1 strength and therefore does 1 damage.

Receiving Damage

Sentries can receive damage from any source, just like a monster. If the Sentry is set to retaliate, it will target any living entity that attacks it, ignoring any current target.

If the Sentry is set to invincible, it takes NO damage or knockback at all!

If the Sentry has criticals turned on, any incoming damage is randomized resulting in a normal hit, a miss, or one of several degrees of critical hit. If the attacker is a player, a message is shown based on the type of hit.

If the Sentry has armor > 0 the damage will be reduced by the amount of armor. If the damage is reduced to nothing, the attack results in a block. Blocked hits cause no damage but DO cause knockback!

Death

If the Sentry's health drops to 0. It dies.

If the Sentry is set to drops on death, when it dies it drops its equipment like a normal monster. Watch out for farmers!

After the respawn delay (default is 10 seconds) the Sentry will respawn.

Lookouts will respawn at their spawn location, by default this is where they were created.

Bodyguards will respawn near their guard target.

Advanced Usage

For combining Sentry and Denizen for truly powerful interactions see Sentry And Denizen

Known caveats and upcoming features

Using commands on a Sentry NPC while it is dead may cause errors. (/npc spawn is safe)

Using /citizens reload may break your sentries or waypoints.

Sentries may get lost or fall through the world.

Mob-type NPCs have some oddities since mc 1.3.1
