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

v. 0.8.8 beta 8/21/2012 Sentries take less knockback based on armor. Also honor the .5 second invulnerable period after hits that other Minecraft entities enjoy. Removed the upper limit on health, strength, and armor. This is for compatibility with other plugins. Vanilla craftbukkit users should still use 1-20 for health, and 0-10 for strength and armor. v. 0.8.8 beta 8/21/2012 Due to pending litigation, all Citizens SentryCorps personnel have been sent to Public Relations training. APPARENTLY some people were upset that Sentries were attacking people with no warning. Added commands warningrange, warning, greeting See #Warn/Greet Fixed sentries giving up on retaliation targets after a few seconds. Other bugfixes. v. 0.8.7.1 beta 8/20/2012 Fix group ignores. Added valid target: entity:all v. 0.8.7 beta 8/20/2012 Added command: ignore Added target entity:owner v. 0.8.6 beta 8/20/2012 Added Target Reassessment When Sentries have an active target, every few seconds they will glance over their shoulders at other possible targets and switch if one has gotten closer. Stab me in the back once, shame on you, stab me in the back twice, shame on me. Added Denizen Command: LIVE v. 0.8.5.1 beta 8/19/2012 Minor fixes to perms, info, debugging info. v. 0.8.5 beta 8/17/2012 Support for Factions. Use FACTION:FactionTag to target memebers of that faction. Added Towny Nation support. Use NATION:NationName to target memebers of that Towny Nation. v. 0.8.4.1 beta 8/16/2012 Last-second heals will no longer allow a sentry to jump back into the fray after death, naked. Sentries forget their target on death, shouldn't smack people nearby on respawn anymore. v. 0.8.4 beta 8/15/2012 KNOWN ISSUE: Sentries with a single waypoint can cause VERY bad lag, either remove the single waypoint or make 2 waypoints until we can correct the issue. Corrected in Citizens2 build #288 KNOWN ISSUE: Human-type NPCs cannot path up stairs or half-blocks Corrected in Citizens2 build #291 If a Sentry NPC is owned by 'server' anyone with the 'citizens.admin' permission can run sentry commands on it. (if they also have the required Sentry permissions) v. 0.8.3 beta 8/15/2012 Fix for group checking with some perms plugins. Default pathfinding range much larger. v. 0.8.2 beta 8/15/2012 Sentries will now take most forms of environmental damage: Armor will be applied against damage from Cacti and TNT. Sentries do not drown or take fall damage (yet) Sentries that die from the environment will still run Scripted Death scripts if at least one player directly damaged them. v. 0.8.1 beta 8/14/2012 Changed arrow-cleanup method. Should work better. Small group permissions compatibility fix. v. 0.8.0 beta 8/13/2012 Built in Towny support. (Thanks TerraNetworkOrg!) 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. v. 0.7.9 beta 8/11/2012 Added animations to projectile shot and healing. Added sound effect to blocked hits. Workaround for Ranged Sentries not pathing after respawn. v. 0.7.8.1 beta 8/11/2012 Fix for denizen change. Fixed 2 NPEs. v. 0.7.8 beta 8/10/2012 Full permissions system for each command in /sentry. See Permissions v. 0.7.7.1 beta 8/10/2012 Integration with Denizen. Now you can trigger scripts on a Sentry's death. Long, drawn-out, guilt-ridden death speeches are go. see Sentry and Denizen for more info. Minor bugfixes. v. 0.7.6 beta 8/8/2012 Added command: healrate Sentries can now heal back health over time. v. 0.7.5 beta 8/7/2012 Added command: spawn All /sentry commands may now be run from the console. Sentry damage is now independent of the weapon equipped. Damage is now equal to the sentry's Strength. The default for new Sentries is 1. If you already have Sentries created be sure to set the Strength, the old default was 0. 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. TO DO: keep bodyguards from trying to stand on top of you and each other. v. 0.7.4 beta 8/6/2012 known bug: cannot target individual hostile monster types, will fix soon Added commands: respawn, guard, nightvision, friendlyfire. Archers have gone back to basic training and can now shoot moving targets with deadly accuracy. Arrows now a move little faster, archers have more range. Sentries can be set to not see targets in dark conditions. Sneaking makes players harder to see. Thief missions Go! Sentries can be set as bodyguards. (note this is not currently persistent and may have bugs) v. 0.7.3 beta 8/4/2012 Added command: attackrate Pyromancer sentries no longer shoot themselves in the face. Tweaked the projectile physics and firing system. Respawn fix and other bugfixes. v. 0.7.2 beta 8/4/2012 Removed ignore-cone, All Sentries now use Line-Of-Sight to select targets. Archers no longer stare at the spot of the last enemy. Code re-arrange. v. 0.7.2 beta 8/4/2012 Added commands: range Sentries ignore a cone of space directly below them. This is to stop archers from shooting at their feet. Fixed sentries being unable to target some mobs such as ghasts. Archers with targets out of range no longer drop arrows at their feet. v. 0.7.1 beta 8/3/2012 Added commands: info, armor, strength All combat (ranged, player-npc, npc-npc, mob-npc) goes through the same calculations for armor, strength, and critical hits. Sentry no longer creates a folder or config.yml. All options are stored within the Citizens saves.yml. More bugfixes and cleanup. v. 0.7.0 beta 8/2/2012 MC 1.3.1 Compatible Added commands: invincible, retaliate, drops, criticals Added ability to shoot bows and projectiles. Sentries respond to damage from arrows. Lots of bugfixes and minor updates. v. 0.5.6 beta Now working with the new builds of C2. v. 0.5.5 beta Fixed bugs. v. 0.5 beta Added the ability to specify targets. Added the ability to set the Health and Speed of a Sentry. 'Stuck' Sentries now respawn after a while. Fixed the death handling. Fixed Sentries remembering their guard location on a restart. v. 0.3 beta Added ability to kill the NPCs. Swords kill faster. Built-in chance of criticals, etc. Fixed targeting code, should be more efficient now. Implemented respawning sequence.

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 have 2 lists: Targets and Ignores. These lists contain entities. Entities can be monsters, passive mobs, players, or player groups. Sentries look at all the possible entities they can see in their range, If it NOT on the Ignores list and IS on the Targets list, the Sentry will attack it. An entity 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, has gotten out of range, or another valid target has gotten closer.
• Ranged Sentries do not follow targets, but will stay on their spot/path and fire at the target until it is dead, out of projectile* range, or another valid target has gotten closer.

*Note that projectile range is not the same as range (detection 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 [entity]

To add an ignore:

/sentry ignore add [entity]

[entity] can be any of the following:

entity:all	All living things. (adding this to the Ignore list is the same as leaving the Target list empty.)
entity:owner	The Sentry's npc Owner.
entity:Name	any mob types with the name Name
entity:monster	All hostile mobs
entity:player	All players and NPCS.
player:Name	The player or NPC with the name Name
group:Name	All members of permissions group Name. Sentries can be added to permission groups.
town:Name	All members of Towny town Name
nation:Name	All members of Towny nation Name
faction:Name	All members of Factions factiontag Name

Examples: This will make the Sentry attack all players except those in the Admin group

/sentry target add entity:player 
/sentry ignore add group:Admin

This will make the Sentry attack anything that moves.. except sheep and the player named Bob.

/sentry target add entity:all
/sentry ignore add entity:sheep
/sentry ignore add player:Bob

To remove a target:

/sentry target remove [target]

To remove a ignore:

/sentry ignore remove [entity]

To view the target list:

/sentry target list

To clear the ignore list:

/sentry ignore clear

Warn/Greet

Sentries can optionally warn or greet Players that come nearby, letting the Player know if the Sentry is hostile or friendly. This is off by default. To turn it on set the WARNINGRANGE higher than 0. This is the number of blocks beyond the RANGE that the Sentry will look for Players to warn/greet. For example if the RANGE is 10 and the WARNINGRANGE is 5, Players 10-15 blocks away will be alerted to the Sentry's hostility.

The warning and greeting message can be customized for each Sentry.

To set the warning message:

/sentry warning 'New Warning Message'>

To set the greetingmessage:

/sentry warning 'New Greeting Message'>

• <PLAYER> and <NPC> can be used in the message as a placeholder for the Player's name or Sentry's name.
• Setting either message to will disable that message.

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

and use /npc path to set waypoints.

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. Set to 0 to prevent normal respawn. Set to -1 and the Sentry will not respawn and be permanently destroyed on death.
WARNINGRANGE	0	0-50	The number of blocks beyond range the Sentry will look for Players to warn or greet. Set to 0 to disable warn/greet.

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. If therespawn is set to 0, the Sentry must be re spawned manually.

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
