Module `Group`

This module contains the GROUP class.

1) Wrapper.Group#GROUP class, extends Wrapper.Controllable#CONTROLLABLE

The Wrapper.Group#GROUP class is a wrapper class to handle the DCS Group objects:

Support all DCS Group APIs.
Enhance with Group specific APIs not in the DCS Group API set.
Handle local Group Controller.
Manage the "state" of the DCS Group.

IMPORTANT: ONE SHOULD NEVER SANATIZE these GROUP OBJECT REFERENCES! (make the GROUP object references nil).

1.1) GROUP reference methods

For each DCS Group object alive within a running mission, a GROUP wrapper object (instance) will be created within the _DATABASE object. This is done at the beginning of the mission (when the mission starts), and dynamically when new DCS Group objects are spawned (using the SPAWN class).

The GROUP class does not contain a :New() method, rather it provides :Find() methods to retrieve the object reference using the DCS Group or the DCS GroupName.

Another thing to know is that GROUP objects do not "contain" the DCS Group object. The GROUP methods will reference the DCS Group object by name when it is needed during API execution. If the DCS Group object does not exist or is nil, the GROUP methods will return nil and log an exception in the DCS.log file.

The GROUP class provides the following functions to retrieve quickly the relevant GROUP instance:

GROUP.Find(): Find a GROUP instance from the _DATABASE object using a DCS Group object.
GROUP.FindByName(): Find a GROUP instance from the _DATABASE object using a DCS Group name.

1.2) GROUP task methods

Several group task methods are available that help you to prepare tasks. These methods return a string consisting of the task description, which can then be given to either a
Wrapper.Controllable#CONTROLLABLE.PushTask or Wrapper.Controllable#CONTROLLABLE.SetTask method to assign the task to the GROUP. Tasks are specific for the category of the GROUP, more specific, for AIR, GROUND or AIR and GROUND. Each task description where applicable indicates for which group category the task is valid. There are 2 main subdivisions of tasks: Assigned tasks and EnRoute tasks.

1.2.1) Assigned task methods

Assigned task methods make the group execute the task where the location of the (possible) targets of the task are known before being detected. This is different from the EnRoute tasks, where the targets of the task need to be detected before the task can be executed.

Find below a list of the assigned task methods:

Wrapper.Controllable#CONTROLLABLE.TaskAttackGroup: (AIR) Attack a Group.
Wrapper.Controllable#CONTROLLABLE.TaskAttackMapObject: (AIR) Attacking the map object (building, structure, e.t.c).
Wrapper.Controllable#CONTROLLABLE.TaskAttackUnit: (AIR) Attack the Unit.
Wrapper.Controllable#CONTROLLABLE.TaskBombing: (Wrapper.Controllable#CONTROLLABLEDelivering weapon at the point on the ground.
Wrapper.Controllable#CONTROLLABLE.TaskBombingRunway: (AIR) Delivering weapon on the runway.
Wrapper.Controllable#CONTROLLABLE.TaskEmbarking: (AIR) Move the group to a Vec2 Point, wait for a defined duration and embark a group.
Wrapper.Controllable#CONTROLLABLE.TaskEmbarkToTransport: (GROUND) Embark to a Transport landed at a location.
Wrapper.Controllable#CONTROLLABLE.TaskEscort: (AIR) Escort another airborne group.
Wrapper.Controllable#CONTROLLABLE.TaskFAC_AttackGroup: (AIR + GROUND) The task makes the group/unit a FAC and orders the FAC to control the target (enemy ground group) destruction.
Wrapper.Controllable#CONTROLLABLE.TaskFireAtPoint: (GROUND) Fire at a VEC2 point until ammunition is finished.
Wrapper.Controllable#CONTROLLABLE.TaskFollow: (AIR) Following another airborne group.
Wrapper.Controllable#CONTROLLABLE.TaskHold: (GROUND) Hold ground group from moving.
Wrapper.Controllable#CONTROLLABLE.TaskHoldPosition: (AIR) Hold position at the current position of the first unit of the group.
Wrapper.Controllable#CONTROLLABLE.TaskLand: (AIR HELICOPTER) Landing at the ground. For helicopters only.
Wrapper.Controllable#CONTROLLABLE.TaskLandAtZone: (AIR) Land the group at a Wrapper.Controllable#CONTROLLABLE.TaskOrbitCircle: (AIR) Orbit at the current position of the first unit of the group at a specified alititude.
Wrapper.Controllable#CONTROLLABLE.TaskOrbitCircleAtVec2: (AIR) Orbit at a specified position at a specified alititude during a specified duration with a specified speed.
Wrapper.Controllable#CONTROLLABLE.TaskRefueling: (AIR) Refueling from the nearest tanker. No parameters.
Wrapper.Controllable#CONTROLLABLE.TaskRoute: (AIR + GROUND) Return a Misson task to follow a given route defined by Points.
Wrapper.Controllable#CONTROLLABLE.TaskRouteToVec2: (AIR + GROUND) Make the Group move to a given point.
Wrapper.Controllable#CONTROLLABLE.TaskRouteToVec3: (AIR + GROUND) Make the Group move to a given point.
Wrapper.Controllable#CONTROLLABLE.TaskRouteToZone: (AIR + GROUND) Route the group to a given zone.
Wrapper.Controllable#CONTROLLABLE.TaskReturnToBase: (AIR) Route the group to an airbase.

1.2.2) EnRoute task methods

EnRoute tasks require the targets of the task need to be detected by the group (using its sensors) before the task can be executed:

Wrapper.Controllable#CONTROLLABLE.EnRouteTaskAWACS: (AIR) Aircraft will act as an AWACS for friendly units (will provide them with information about contacts). No parameters.
Wrapper.Controllable#CONTROLLABLE.EnRouteTaskEngageGroup: (AIR) Engaging a group. The task does not assign the target group to the unit/group to attack now; it just allows the unit/group to engage the target group as well as other assigned targets.
Wrapper.Controllable#CONTROLLABLE.EnRouteTaskEngageTargets: (AIR) Engaging targets of defined types.
Wrapper.Controllable#CONTROLLABLE.EnRouteTaskEWR: (AIR) Attack the Unit.
Wrapper.Controllable#CONTROLLABLE.EnRouteTaskFAC: (AIR + GROUND) The task makes the group/unit a FAC and lets the FAC to choose a targets (enemy ground group) around as well as other assigned targets.
Wrapper.Controllable#CONTROLLABLE.EnRouteTaskFAC_EngageGroup: (AIR + GROUND) The task makes the group/unit a FAC and lets the FAC to choose the target (enemy ground group) as well as other assigned targets.
Wrapper.Controllable#CONTROLLABLE.EnRouteTaskTanker: (AIR) Aircraft will act as a tanker for friendly units. No parameters.

1.2.3) Preparation task methods

There are certain task methods that allow to tailor the task behaviour:

Wrapper.Controllable#CONTROLLABLE.TaskWrappedAction: Return a WrappedAction Task taking a Command.
Wrapper.Controllable#CONTROLLABLE.TaskCombo: Return a Combo Task taking an array of Tasks.
Wrapper.Controllable#CONTROLLABLE.TaskCondition: Return a condition section for a controlled task.
Wrapper.Controllable#CONTROLLABLE.TaskControlled: Return a Controlled Task taking a Task and a TaskCondition.

1.2.4) Obtain the mission from group templates

Group templates contain complete mission descriptions. Sometimes you want to copy a complete mission from a group and assign it to another:

Wrapper.Controllable#CONTROLLABLE.TaskMission: (AIR + GROUND) Return a mission task from a mission template.

1.3) GROUP Command methods

Group command methods prepare the execution of commands using the Wrapper.Controllable#CONTROLLABLE.SetCommand method:

Wrapper.Controllable#CONTROLLABLE.CommandDoScript: Do Script command.
Wrapper.Controllable#CONTROLLABLE.CommandSwitchWayPoint: Perform a switch waypoint command.

1.4) GROUP Option methods

Group Option methods change the behaviour of the Group while being alive.

1.4.1) Rule of Engagement:

To check whether an ROE option is valid for a specific group, use:

1.4.2) Rule on thread:

To test whether an ROT option is valid for a specific group, use:

1.5) GROUP Zone validation methods

The group can be validated whether it is completely, partly or not within a Zone. Use the following Zone validation methods on the group:

GROUP.IsCompletelyInZone: Returns true if all units of the group are within a Zone.
GROUP.IsPartlyInZone: Returns true if some units of the group are within a Zone.
GROUP.IsNotInZone: Returns true if none of the group units of the group are within a Zone.

The zone can be of any Zone class derived from Core.Zone#ZONE_BASE. So, these methods are polymorphic to the zones tested on.
