--- **Functional** - (R2.4) Control artillery units.
--
-- ===
--
-- The ARTY class can be used to easily assign and manage targets for artillery units.
--
-- ## Features:
--
-- * Multiple targets can be assigned. No restriction on number of targets.
-- * Targets can be given a priority. Engagement of targets is executed a according to their priority.
-- * Engagements can be scheduled, i.e. will be executed at a certain time of the day.
-- * Special weapon types can be selected for each attack, e.g. cruise missiles for Naval units.
-- * Automatic rearming once the artillery is out of ammo.
-- * New targets can be added during the mission, e.g. when they are detected by recon units.
-- * Finite state machine implementation. Mission designer can interact when certain events occur.

-- @extends Core.Fsm#FSM_CONTROLLABLE
--- Enables mission designers easily to assign targets for artillery units. Since the implementation is based on a Finite State Model (FSM), the mission designer can
-- interact with the process at certain events or states.
--
-- A new ARTY object can be created with the @{#ARTY.New}(*group*) contructor.
-- The parameter *group* has to be a MOOSE Group object and defines ARTY group.
--
-- The ARTY FSM process can be started by the @{#ARTY.Start}() command.
--
-- ## The ARTY Process
--
-- ![Process](..\Presentations\ARTY\ARTY_Process.png)
--
-- ### Blue Branch
-- After the FMS process is started the ARTY group will be in the state **CombatReady**. Once a target is assigned the **OpenFire** event will be triggered and the group starts
-- firing. At this point the group in in the state **Firing**.
-- When the defined number of shots has been fired on the current target the event **CeaseFire** is triggered. The group will stop firing and go back to the state **CombatReady**.
-- If another target is defined (or multiple engagements of the same target), the cycle starts anew.
--
-- ### Violet Branch
-- When the ARTY group runs out of ammunition, the event **Winchester** is triggered and the group enters the state **OutOfAmmo**.
-- In this state, the group is unable to engage further targets.
--
-- ### Red Branch
-- With the @{#ARTY.SetRearmingGroup}(*group*) command, a special group can be defined to rearm the ARTY group. If this unit has been assigned and the group has entered the state
-- **OutOfAmmo** the event **Rearm** is triggered followed by a transition to the state **Rearming**.
-- If the rearming group is less than 100 meters away from the ARTY group, the rearming process starts. If the rearming group is more than 100 meters away from the ARTY unit, the
-- rearming group is routed to a point 20 to 100 m from the ARTY group.
--
-- Once the rearming is complete, the **Rearmed** event is triggered and the group enters the state **CombatReady**. At this point targeted can be engaged again.
--
-- ### Green Branch
-- The ARTY group can be ordered to change its position via the @{#ARTY.AssignMoveCoord}() function as described below. When the group receives the command to move
-- the event **Move** is triggered and the state changes to **Moving**. When the unit arrives to its destination the event **Arrived** is triggered and the group
-- becomes **CombatReady** again.
--
-- Note, that the ARTY group will not open fire while it is in state **Moving**. This property differentiates artillery from tanks.
--
-- ### Yellow Branch
-- When a new target is assigned via the @{#ARTY.AssignTargetCoord}() function (see below), the **NewTarget** event is triggered.
--
-- ## Assigning Targets
-- Assigning targets is a central point of the ARTY class. Multiple targets can be assigned simultanioulsly and are put into a queue.
-- Of course, targets can be added at any time during the mission. For example, once they are detected by a reconnaissance unit.
--
-- In order to add a target, the function @{#ARTY.AssignTargetCoord}(*coord*, *prio*, *radius*, *nshells*, *maxengage*, *time*, *weapontype*, *name*) has to be used.
-- Only the first parameter *coord* is mandatory while all remaining parameters are all optional.
--
-- ### Parameters:
--
-- * *coord*: Coordinates of the target, given as @{Core.Point#COORDINATE} object.
-- * *prio*: Priority of the target. This a number between 1 (high prio) and 100 (low prio). Targets with higher priority are engaged before targets with lower priority.
-- * *radius*: Radius in meters which defines the area the ARTY group will attempt to be hitting. Default is 100 meters.
-- * *nshells*: Number of shots (shells, rockets, missiles) fired by the group at each engagement of a target. Default is 5.
-- * *maxengage*: Number of times a target is engaged.
-- * *time*: Time of day the engagement is schedule in the format "hh:mm:ss" for hh=hours, mm=minutes, ss=seconds.
-- For example "10:15:35". In the case the attack will be executed at a quarter past ten in the morning at the day the mission started.
-- If the engagement should start on the following day the format can be specified as "10:15:35+1", where the +1 denots the following day.
-- This is useful for longer running missions or if the mission starts at 23:00 hours and the attack should be scheduled at 01:00 hours on the following day.
-- Of course, later days are also possible by appending "+2", "+3", etc.
-- **Note** that the time has to be given as a string. So the enclosing quotation marks "" are important.
-- * *weapontype*: Specified the weapon type that should be used for this attack if the ARTY group has multiple weapons to engage the target.
-- For example, this is useful for naval units which carry a bigger arsenal (cannons and missiles). Default is Auto, i.e. DCS logic selects the appropriate weapon type.
-- *name*: A special name can be defined for this target. Default name are the coordinates of the target in LL DMS format. If a name is already given for another target
-- or the same target should be attacked two or more times with different parameters a suffix "#01", "#02", "#03" is automatically appended to the specified name.
--
-- ## Target Queue
-- In case multiple targets have been defined, it is important to understand how the target queue works.
--
-- Here, the essential parameters are the priority *prio*, the number of engagements *maxengage* and the scheduled *time* as described above.
--
-- For example, we have assigned two targets one with *prio*=10 and the other with *prio*=50 and both targets should be engaged three times (*maxengage*=3).
-- Let's first consider the case that none of the targets is scheduled to be executed at a certain time (*time*=nil).
-- The ARTY group will first engage the target with higher priority (*prio*=10). After the engagement is finished, the target with lower priority is attacked.
-- This is because the target with lower prio has been attacked one time less. After the attack on the lower priority task is finished and both targets
-- have been engaged equally often, the target with the higher priority is engaged again. This coninues until a target has engaged three times.
-- Once the maximum number of engagements is reached, the target is deleted from the queue.
--
-- In other words, the queue is first sorted with respect to the number of engagements and targets with the same number of engagements are sorted with
-- respect to their priority.
--
-- ### Timed Engagements
--
-- As mentioned above, targets can be engaged at a specific time of the day via the *time* parameter.
--
-- If the *time* parameter is specified for a target, the first engagement of that target will happen at that time of the day and not before.
-- This also applies when multiple engagements are requested via the *maxengage* parameter. The first attack will not happen before the specifed time.
-- When that timed attack is finished, the *time* parameter is deleted and the remaining engagements are carried out in the same manner as for untimed targets (described above).
--
-- Of course, it can happen that a scheduled task should be executed at a time, when another target is already under attack.
-- If the priority of the target is higher than the priority of the current target, then the current attack is cancelled and the engagement of the target with the higher
-- priority is started.
--
-- By contrast, if the current target has a higher priority than the target scheduled at that time, the current attack is finished before the scheduled attack is started.
--
-- ## Determining the Amount of Ammo
--
-- In order to determin when a unit is out of ammo and possible initiate the rearming process it is necessary to know which types of weapons have to be counted.
-- For most artillery unit types, this is simple because they only have one type of weapon and hence ammunition.
--
-- However, there are more complex scenarios. For example, naval units carry a big arsenal of different ammunition types ranging from various cannon shell types
-- over surface-to-air missiles to cruise missiles. Obviously, not all of these ammo types can be employed for artillery tasks.
--
-- Unfortunately, there is no easy way to count only those ammo types useable as artillery. Therefore, to keep the implementation general the user
-- can specify the names of the ammo types by the following functions:
--
-- * @{#ARTY.SetShellTypes}(*tableofnames*): Defines the ammo types for unguided cannons. Default is *tableofnames*={"weapons.shells"}, i.e. **all** types of shells are counted.
-- * @{#ARTY.SetRocketTypes}(*tableofnames*): Defines the ammo types of unguided rockets. Default is *tableofnames*={"weapons.nurs"}, i.e. **all** types of rockets are counted.
-- * @{#ARTY.SetMissileTypes}(*tableofnames*): Defines the ammo types of guided missiles. Default is *tableofnames*={"weapons.missiles"}, i.e. **all** types of missiles are counted.
--
-- **Note** that the default parameters "weapons.shells", "weapons.nurs", "weapons.missiles" **should in priciple** capture all the corresponding ammo types.
-- However, the logic searches for the string "weapon.missies" in the ammo type. Especially for missiles, this string is often not contained in the ammo type descriptor.
--
-- One way to determin which types of ammo the unit carries, one can use the debug mode of the arty class via @{#ARTY.SetDebugON}().
-- In debug mode, the all ammo types of the group are printed to the monitor as message and can be found in the DCS.log file.
--
-- ## Empoying Selected Weapons
--
-- If an ARTY group carries multiple weapons, which can be used for artillery task, a certain weapon type can be selected to attack the target.
-- This is done via the *weapontype* parameter of the @{#ARTY.AssignTargetCoord}(..., *weapontype*, ...) function.
--
-- The enumerator @{#ARTY.WeaponType} has been defined to select a certain weapon type. Supported values are:
--
-- * @{#ARTY.WeaponType}.Auto: Automatic weapon selection by the DCS logic. This is the default setting.
-- * @{#ARTY.WeaponType}.Cannon: Only cannons are used during the attack. Corresponding ammo type are shells and can be defined by @{#ARTY.SetShellTypes}.
-- * @{#ARTY.WeaponType}.Rockets: Only unguided are used during the attack. Corresponding ammo type are rockets/nurs and can be defined by @{#ARTY.SetRocketTypes}.
-- * @{#ARTY.WeaponType}.UnguidedAny: Any unguided weapon (cannons or rockes) will be used.
-- * @{#ARTY.WeaponType}.GuidedMissile: Any guided missiles are used during the attack. Corresponding ammo type are missiles and can be defined by @{#ARTY.SetMissileTypes}.
-- * @{#ARTY.WeaponType}.CruiseMissile: Only cruise missiles are used during the attack. Corresponding ammo type are missiles and can be defined by @{#ARTY.SetMissileTypes}.
--
-- ## Assigning Moves
-- The ARTY group can be commanded to move. This is done by the @{#ARTY.AssignMoveCoord}(*coord*,*time*,*speed*,*onroad*,*cancel*,*name*) function.
-- With this multiple timed moves of the group can be scheduled easily. By default, these moves will only be executed if the group is state **CombatReady**.
--
-- ### Parameters
--
-- * *coord*: Coordinates where the group should move to given as @{Core.Point#COORDINATE} object.
-- * *time*: The time when the move should be executed. This has to be given as a string in the format "hh:mm:ss" (hh=hours, mm=minutes, ss=seconds).
-- * *speed*: Speed of the group in km/h.
-- * *onroad*: If this parameter is set to true, the group uses mainly roads to get to the commanded coordinates.
-- * *cancel*: If set to true, any current engagement of targets is cancelled at the time the move should be executed.
-- * *name*: Can be used to set a user defined name of the move. By default the name is created from the LL DMS coordinates.
--
-- ## Automatic Rearming
--
-- If an ARTY group runs out of ammunition, it can be rearmed automatically.
--
-- ### Rearming Group
-- The first way to activate the automatic rearming is to define a rearming group with the function @{#ARTY.SetRearmingGroup}(*group*). For the blue side, this
-- could be a M181 transport truck and for the red side an Ural-375 truck.
--
-- Once the ARTY group is out of ammo and the **Rearm** event is triggered, the defined rearming truck will drive to the ARTY group.
-- So the rearming truck does not have to be placed nearby the artillery group. When the rearming is complete, the rearming truck will drive back to its original position.
--
-- ### Rearming Place
-- The second alternative is to define a rearming place, e.g. a FRAP, airport or any other warehouse. This is done with the function @{#ARTY.SetRearmingPlace}(*coord*).
-- The parameter *coord* specifies the coordinate of the rearming place which should not be further away then 100 meters from the warehouse.
--
-- When the **Rearm** event is triggered, the ARTY group will move to the rearming place. Of course, the group must be mobil. So for a mortar this rearming procedure would not work.
--
-- After the rearming is complete, the ARTY group will move back to its original position and resume normal operations.
--
-- ### Rearming Group **and** Rearming Place
-- If both a rearming group *and* a rearming place are specified like described above, both the ARTY group and the rearming truck will move to the rearming place and meet there.
--
-- After the rearming is complete, both groups will move back to their original positions.
--
-- ## Fine Tuning
--
-- The mission designer has a few options to tailor the ARTY object according to his needs.
--
-- * @{#ARTY.RemoveAllTargets}() removes all targets from the target queue.
-- * @{#ARTY.RemoveTarget}(*name*) deletes the target with *name* from the target queue.
-- * @{#ARTY.SetMaxFiringRange}(*range*) defines the maximum firing range. Targets further away than this distance are not engaged.
-- * @{#ARTY.SetMinFiringRange}(*range*) defines the minimum firing range. Targets closer than this distance are not engaged.
-- * @{#ARTY.SetRearmingGroup}(*group*) sets the group resposible for rearming of the ARTY group once it is out of ammo.
-- * @{#ARTY.SetReportON}() and @{#ARTY.SetReportOFF}() can be used to enable/disable status reports of the ARTY group send to all coalition members.
-- * @{#ARTY.SetWaitForShotTime}(*waittime*) sets the time after which a target is deleted from the queue if no shooting event occured after the target engagement started.
-- Default is 300 seconds. Note that this can for example happen, when the assigned target is out of range.
-- * @{#ARTY.SetDebugON}() and @{#ARTY.SetDebugOFF}() can be used to enable/disable the debug mode.
--
-- ## Examples
--
-- ### Assigning Multiple Targets
-- This basic example illustrates how to assign multiple targets and defining a rearming group.
-- -- Creat a new ARTY object from a Paladin group.
-- paladin=ARTY:New(GROUP:FindByName("Blue Paladin"))
--
-- -- Define a rearming group. This is a Transport M818 truck.
-- paladin:SetRearmingGroup(GROUP:FindByName("Blue Ammo Truck"))
--
-- -- Set the max firing range. A Paladin unit has a range of 20 km.
-- paladin:SetMaxFiringRange(20)
--
-- -- Low priorty (90) target, will be engage last. Target is engaged two times. At each engagement five shots are fired.
-- paladin:AssignTargetCoord(GROUP:FindByName("Red Targets 3"):GetCoordinate(), 90, nil, 5, 2)
-- -- Medium priorty (nil=50) target, will be engage second. Target is engaged two times. At each engagement ten shots are fired.
-- paladin:AssignTargetCoord(GROUP:FindByName("Red Targets 1"):GetCoordinate(), nil, nil, 10, 2)
-- -- High priorty (10) target, will be engage first. Target is engaged three times. At each engagement twenty shots are fired.
-- paladin:AssignTargetCoord(GROUP:FindByName("Red Targets 2"):GetCoordinate(), 10, nil, 20, 3)
--
-- -- Start ARTY process.
-- paladin:Start()
-- **Note**
--
-- * If a parameter should be set to its default value, it has to be set to *nil* if other non-default parameters follow. Parameters at the end can simply be skiped.
-- * In this example, the target coordinates are taken from groups placed in the mission edit using the COORDINATE:GetCoordinate() function.
--
-- ### Scheduled Engagements
-- -- Mission starts at 8 o'clock.
-- -- Assign two scheduled targets.
--
-- -- Create ARTY object from Paladin group.
-- paladin=ARTY:New(GROUP:FindByName("Blue Paladin"))
--
-- -- Assign target coordinates. Priority=50 (medium), radius=100 m, use 5 shells per engagement, engage 1 time at two past 8 o'clock.
-- paladin:AssignTargetCoord(GROUP:FindByName("Red Targets 1"):GetCoordinate(), 50, 100, 5, 1, "08:02:00", ARTY.WeaponType.Auto, "Target 1")
--
-- -- Assign target coordinates. Priority=10 (high), radius=300 m, use 10 shells per engagement, engage 1 time at seven past 8 o'clock.
-- paladin:AssignTargetCoord(GROUP:FindByName("Red Targets 2"):GetCoordinate(), 10, 300, 10, 1, "08:07:00", ARTY.WeaponType.Auto, "Target 2")
--
-- -- Start ARTY process.
-- paladin:Start()
--
-- ### Specific Weapons
-- This example demonstrates how to use specific weapons during an engagement.
-- -- Define the Normandy as ARTY object.
-- normandy=ARTY:New(GROUP:FindByName("Normandy"))
--
-- -- Add target: prio=50, radius=300 m, number of missiles=20, number of engagements=1, start time=08:05 hours, only use cruise missiles for this attack.
-- normandy:AssignTargetCoord(GROUP:FindByName("Red Targets 1"):GetCoordinate(), 20, 300, 50, 1, "08:01:00", ARTY.WeaponType.CruiseMissile)
--
-- -- Add target: prio=50, radius=300 m, number of shells=100, number of engagements=1, start time=08:15 hours, only use cannons during this attack.
-- normandy:AssignTargetCoord(GROUP:FindByName("Red Targets 1"):GetCoordinate(), 50, 300, 100, 1, "08:15:00", ARTY.WeaponType.Cannon)
--
-- -- Define shells that are counted to check whether the ship is out of ammo.
-- -- Note that this is necessary because the Normandy has a lot of other shell type weapons which cannot be used to engage ground targets in an artillery style manner.
-- normandy:SetShellTypes({"MK45_127"})
--
-- -- Define missile types that are counted.
-- normandy:SetMissileTypes({"BGM"})
--
-- -- Start ARTY process.
-- normandy:Start()
