The AI_AIR_PATROL class implements the core functions to patrol a Core.Zone by an AI Wrapper.Group and automatically engage any airborne enemies that are within a certain range or within a certain zone. |
The AI_AIR_PATROL class implements the core functions to patrol a Core.Zone by an AI Wrapper.Group and automatically engage any airborne enemies that are within a certain range or within a certain zone.
The AI_AIR_PATROL is assigned a Wrapper.Group and this must be done before the AI_AIR_PATROL 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.
When enemies are detected, the AI will automatically engage the enemy.
Until a fuel or damage threshold has been reached by the AI, or when the AI is commanded to RTB. When the fuel threshold has been reached, the airplane will fly towards the nearest friendly airbase and will land.
1. AI_AIR_PATROL constructor
- AI_AIR_PATROL.New(): Creates a new AI_AIR_PATROL object.
2. AI_AIR_PATROL is a FSM
2.1 AI_AIR_PATROL States
- None ( Group ): The process is not started yet.
- Patrolling ( Group ): The AI is patrolling the Patrol Zone.
- Engaging ( Group ): The AI is engaging the bogeys.
- Returning ( Group ): The AI is returning to Base..
2.2 AI_AIR_PATROL Events
- **AI.AI_Patrol#AI_PATROL_ZONE.Start**: Start the process.
- **AI.AI_Patrol#AI_PATROL_ZONE.PatrolRoute**: Route the AI to a new random 3D point within the Patrol Zone.
- **AI_AIR_PATROL.Engage**: Let the AI engage the bogeys.
- **AI_AIR_PATROL.Abort**: Aborts the engagement and return patrolling in the patrol zone.
- **AI.AI_Patrol#AI_PATROL_ZONE.RTB**: Route the AI to the home base.
- **AI.AI_Patrol#AI_PATROL_ZONE.Detect**: The AI is detecting targets.
- **AI.AI_Patrol#AI_PATROL_ZONE.Detected**: The AI has detected new targets.
- **AI_AIR_PATROL.Destroy**: The AI has destroyed a bogey Wrapper.Unit.
- **AI_AIR_PATROL.Destroyed**: The AI has destroyed all bogeys Wrapper.Units assigned in the CAS task.
- Status ( Group ): The AI is checking status (fuel and damage). When the thresholds have been reached, the AI will RTB.
3. Set the Range of Engagement
An optional range can be set in meters, that will define when the AI will engage with the detected airborne enemy targets. The range can be beyond or smaller than the range of the Patrol Zone. The range is applied at the position of the AI. Use the method AI_AIR_PATROL.SetEngageRange() to define that range.
Developer Note
Note while this class still works, it is no longer supported as the original author stopped active development of MOOSE Therefore, this class is considered to be deprecated

The lowest altitude in meters where to execute the patrol.
DCS#Altitude PatrolCeilingAltitude

Return value:
self
When the AI is damaged beyond a certain threshold, it is required that the AI returns to the home base.
However, damage cannot be foreseen early on. Therefore, when the damage threshold 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 threshold will be 0.25.
Defined in:
Parameter:
#number PatrolDamageThreshold
The threshold in percentage (between 0 and 1) when the AI is considered to be damaged.
Return value:
self
Sets the disengage range, that when engaging a target beyond the specified range, the engagement will be cancelled and the plane will RTB.
Defined in:
Parameter:
#number DisengageRadius
The disengage range.
Return value:
self
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 threshold is calculated. When the fuel threshold is reached, the AI will continue for a given time its patrol task in orbit, while a new AIControllable is targeted to the AI_AIR. Once the time is finished, the old AI will return to the base.
Defined in:
Parameters:
#number FuelThresholdPercentage
The threshold in percentage (between 0 and 1) when the AIControllable is considered to get out of fuel.
#number OutOfFuelOrbitTime
The amount of seconds the out of fuel AIControllable will orbit before returning to the base.
Return value:
self
Sets the home airbase.
Sets (modifies) the minimum and maximum RTB speed of the patrol.
Defined in:
Parameters:
DCS#Speed RTBMinSpeed
The minimum speed of the Wrapper.Controllable in km/h.
DCS#Speed RTBMaxSpeed
The maximum speed of the Wrapper.Controllable in km/h.
Return value:
self
Set the min and max factors on RTB speed.
Use this, if your planes are heading back to base too fast. Default values are 0.5 and 0.6. The RTB speed is calculated as the max speed of the unit multiplied by MinFactor (lower bracket) and multiplied by MaxFactor (upper bracket). A random value in this bracket is then applied in the waypoint routing generation.
Defined in:
Parameters:
#number MinFactor
Lower bracket factor. Defaults to 0.5.
#number MaxFactor
Upper bracket factor. Defaults to 0.6.
Return value:
self
Sets (modifies) the minimum and maximum speed of the patrol.
Defined in:
