OPEN ISSUES
2017-01-17: When Spawned AI is located at an airbase, it will be routed first back to the airbase after take-off.
2016-01-17: -- Fixed problem with AI returning to base too early and unexpected. -- ReSpawning of AI will reset the AI_PATROL and derived classes. -- Checked the correct workings of SCHEDULER, and it DOES work correctly.

AIPATROLZONE class, extends Fsm#FSM_CONTROLLABLE
The AIPATROLZONE class implements the core functions to patrol a Zone by an AI Controllable or Group.
The AIPATROLZONE is assigned a Group and this must be done before the AIPATROLZONE process can be started using the Start event.
The AI will fly towards the random 3D point within the patrol zone, using a random speed within the given altitude and speed limits. Upon arrival at the 3D point, a new random 3D point will be selected within the patrol zone using the given limits.
This cycle will continue.
During the patrol, the AI will detect enemy targets, which are reported through the Detected event.
-- Note that the enemy is not engaged! To model enemy engagement, either tailor the Detected event, or use derived AI_ classes to model AI offensive or defensive behaviour.
Until a fuel or damage treshold has been reached by the AI, or when the AI is commanded to RTB. When the fuel treshold has been reached, the airplane will fly towards the nearest friendly airbase and will land.
1. AIPATROLZONE constructor
- AIPATROLZONE.New(): Creates a new AIPATROLZONE object.
2. AIPATROLZONE is a FSM
2.1. AIPATROLZONE States
- None ( Group ): The process is not started yet.
- Patrolling ( Group ): The AI is patrolling the Patrol Zone.
- Returning ( Group ): The AI is returning to Base.
- Stopped ( Group ): The process is stopped.
- Crashed ( Group ): The AI has crashed or is dead.
2.2. AIPATROLZONE Events
- Start ( Group ): Start the process.
- Stop ( Group ): Stop the process.
- Route ( Group ): Route the AI to a new random 3D point within the Patrol Zone.
- RTB ( Group ): Route the AI to the home base.
- Detect ( Group ): The AI is detecting targets.
- Detected ( Group ): The AI has detected new targets.
- Status ( Group ): The AI is checking status (fuel and damage). When the tresholds have been reached, the AI will RTB.
3. Set or Get the AI controllable
- AIPATROLZONE.SetControllable(): Set the AIControllable.
- AIPATROLZONE.GetControllable(): Get the AIControllable.
4. Set the Speed and Altitude boundaries of the AI controllable
- AIPATROLZONE.SetSpeed(): Set the patrol speed boundaries of the AI, for the next patrol.
- AIPATROLZONE.SetAltitude(): Set altitude boundaries of the AI, for the next patrol.
5. Manage the detection process of the AI controllable
The detection process of the AI controllable can be manipulated. Detection requires an amount of CPU power, which has an impact on your mission performance. Only put detection on when absolutely necessary, and the frequency of the detection can also be set.
- AIPATROLZONE.SetDetectionOn(): Set the detection on. The AI will detect for targets.
- AIPATROLZONE.SetDetectionOff(): Set the detection off, the AI will not detect for targets. The existing target list will NOT be erased.
The detection frequency can be set with AIPATROLZONE.SetDetectionInterval( seconds ), where the amount of seconds specify how much seconds will be waited before the next detection. Use the method AIPATROLZONE.GetDetectedUnits() to obtain a list of the Units detected by the AI.
The detection can be filtered to potential targets in a specific zone. Use the method AIPATROLZONE.SetDetectionZone() to set the zone where targets need to be detected. Note that when the zone is too far away, or the AI is not heading towards the zone, or the AI is too high, no targets may be detected according the weather conditions.
6. Manage the "out of fuel" in the AIPATROLZONE
When the AI is out of fuel, it is required that a new AI is started, before the old AI can return to the home base. Therefore, with a parameter and a calculation of the distance to the home base, the fuel treshold is calculated. When the fuel treshold is reached, the AI will continue for a given time its patrol task in orbit, while a new AI is targetted to the AIPATROLZONE. Once the time is finished, the old AI will return to the base. Use the method AIPATROLZONE.ManageFuel() to have this proces in place.
7. Manage "damage" behaviour of the AI in the AIPATROLZONE
When the AI is damaged, it is required that a new AIControllable is started. However, damage cannon be foreseen early on. Therefore, when the damage treshold is reached, the AI will return immediately to the home base (RTB). Use the method AIPATROLZONE.ManageDamage() to have this proces in place.

Type AI_PATROL_ZONE
AIPATROLZONE class
Field(s)
- #boolean AI_PATROL_ZONE.CheckStatus
- AI_PATROL_ZONE:ClearDetectedUnits()
-
Clears the list of Unit#UNITs that were detected by the AI.
- AI_PATROL_ZONE:Detect()
-
Synchronous Event Trigger for Event Detect.
- #boolean AI_PATROL_ZONE.DetectActivated
- #boolean AI_PATROL_ZONE.DetectOn
- AI_PATROL_ZONE:Detected()
-
Synchronous Event Trigger for Event Detected.
- AI_PATROL_ZONE.DetectedUnits
-
This table contains the targets detected during patrol.
- AI_PATROL_ZONE:GetDetectedUnits()
-
Gets a list of Unit#UNITs that were detected by the AI.
No filtering is applied, so, ANY detected UNIT can be in this list. It is up to the mission designer to use the Unit class and methods to filter the targets.
Return value
#table: The list of Unit#UNITs
- AI_PATROL_ZONE:ManageDamage(PatrolDamageTreshold)
-
When the AI is damaged beyond a certain treshold, it is required that the AI returns to the home base.
However, damage cannot be foreseen early on. Therefore, when the damage treshold is reached, the AI will return immediately to the home base (RTB). Note that for groups, the average damage of the complete group will be calculated. So, in a group of 4 airplanes, 2 lost and 2 with damage 0.2, the damage treshold will be 0.25.
Parameter
-
#number PatrolDamageTreshold: The treshold in percentage (between 0 and 1) when the AI is considered to be damaged.
Return value
#AIPATROLZONE: self
-
- AI_PATROL_ZONE:ManageFuel(PatrolFuelTresholdPercentage, PatrolOutOfFuelOrbitTime)
-
When the AI is out of fuel, it is required that a new AI is started, before the old AI can return to the home base.
Therefore, with a parameter and a calculation of the distance to the home base, the fuel treshold is calculated. When the fuel treshold is reached, the AI will continue for a given time its patrol task in orbit, while a new AIControllable is targetted to the AIPATROLZONE. Once the time is finished, the old AI will return to the base.
Parameters
-
#number PatrolFuelTresholdPercentage: The treshold in percentage (between 0 and 1) when the AIControllable is considered to get out of fuel. -
#number PatrolOutOfFuelOrbitTime: The amount of seconds the out of fuel AIControllable will orbit before returning to the base.
