pushTask() with a new waypoint to an existing tanker doesn't work.

[TEMPEST.114]

I have a tanker created in the ME that is working perfectly.

It's taking off, flying to a waypoint, and starting a race-track from that waypoint to the next (it's penultimate wp - the last being land back at base).

The TACAN, EPLRS etc is all set and players can tank from it.

In my script I give it a new waypoint some distance away (to simulate the front of the battle moving and returning players needing fuel to get home).

This new position is a waypoint with a new task of ORBIT i.e. NOT Race-Track, with a new altitude and speed and obviously, new location.

Here is the task I'm creating prior to doing the 'pushTask(missionTask)' command.

missionTask =
{
	['id'] = 'Mission',
	['params'] = {
		['route'] = {
			['points'] = {
				[1] = {
					['speed_locked'] = true,
					['type'] = 'Turning Point',
					['action'] = 'Turning Point',
					['alt_type'] = 'BARO',
					['y'] = -171753.07753682,
					['x'] = -74403.995537434,
					['speed'] = 494.08524741803,
					['task'] = {
						['id'] = 'ComboTask',
						['params'] = {
							['tasks'] = {
								[1] = {
									['id'] = 'Tanker',
									['params'] = {

									}
								},
								[2] = {
									['id'] = 'Orbit',
									['params'] = {
										['altitude'] = 6093.019511968,
										['pattern'] = 'Circle',
										['speed'] = 494.08524741803
									}
								}
							}
						}
					},
					['alt'] = 6093.019511968
				}
			}
		},
		['airborne'] = true
	}
}

 

And here is the Tankers default tasks as set from the mission editor (as extracted from env.mission PRIOR to any push)

And here is my code for creating and pushing the new task

function MoveTankerTask(playerData)

  local point = GetMoveToPoint()
  
  if point.x and point.y and point.z then

    local missionTask = BuildAircraftTaskFrom(point, playerData.selectedTanker.speed, playerData.selectedTanker.altitude, true)
 
    PushNewTaskForGroup(missionTask, playerData.selectedTanker.group)
	
  end

end



function BuildAircraftTaskFrom(destinationPoint, speed, altitude, isAircraft)

  isAircraft = isAircraft or false

  local missionTask               = {}
  missionTask.id                  = "Mission"
  missionTask.params              = {}
  missionTask.params.route        = {}
  missionTask.params.route.points = {}

  if isAircraft then missionTask.params.airborne = true end

  missionTask.params.route.points[#missionTask.params.route.points+1] = CreateBasicOrbittingAircraftUnitWaypoints(destinationPoint, speed, altitude)

  return missionTask

end



function CreateBasicOrbittingAircraftUnitWaypoints(destinationPoint, speed, altitude) -- Goes into POINTS

  local waypoint = {}

  waypoint.x                 = destinationPoint.x
  waypoint.y                 = destinationPoint.z
  waypoint.alt               = altitude
  waypoint.alt_type          = "BARO"
  waypoint.speed             = speed
  waypoint.action            = AI.Task.TurnMethod.FLY_OVER_POINT
  waypoint.type              = AI.Task.WaypointType.TURNING_POINT
  waypoint.speed_locked      = true
  waypoint.task              = {}
  waypoint.task.id           = "ComboTask"
  waypoint.task.params       = {}
  waypoint.task.params.tasks = {}

  local orbitTask =
  {
      ["id"]      = "Orbit",
      ["params"]  = {}
  }

  orbitTask.params.altitude = altitude
  orbitTask.params.pattern  = "Circle"
  orbitTask.params.speed    = speed

  waypoint.task.params.tasks[#waypoint.task.params.tasks+1] = orbitTask

  return waypoint

end


function PushNewTaskForGroup(missionTask, group)

  group:getController():pushTask(missionTask)

end

 

So, if I don't push the new task, the tanker just does its regular race-track pattern between two waypoints just fine.

When I push this new task, it deviates from it's race-track course for a few minutes but then returns back to its racetrack course and carries on as if nothing happened.

 

If I popTask() before I push the new one, it makes no difference.

 

I can't see anything wrong with this.

HOWEVER, if I use 'setTask' and recreate the entire Tanker Task from scratch i.e. recreate the tacan, eplrs, tanker -a and the new waypoint information and SET that - then it loses the old racetrack pattern and moves CORRECTLY to the new position and does the circular orbit as I expect.

 

Therefore I conclude that PUSH with a correctly formatted waypoint for a tanker, at least, is broken.
