# Ideally we would use the escort mission type and escort task to have
|
|
# the AI automatically but the AI only escorts AI flights while they are
|
|
# traveling between waypoints. When an AI flight performs an attack
|
|
# (such as attacking the mission target), AI escorts wander aimlessly
|
|
# until the escorted group resumes its flight plan.
|
|
#
|
|
# As such, we instead use the Search Then Engage task, which is an
|
|
# enroute task that causes the AI to follow their flight plan and engage
|
|
# enemies of the set type within a certain distance. The downside to
|
|
# this approach is that AI escorts are no longer related to the group
|
|
# they are escorting, aside from the fact that they fly a similar flight
|
|
# plan at the same time. With Escort, the escorts will follow the
|
|
# escorted group out of the area. The strike element may or may not fly
|
|
# directly over the target, and they may or may not require multiple
|
|
# attack runs. For the escort flight we must just assume a flight plan
|
|
# for the escort to fly. If the strike flight doesn't need to overfly
|
|
# the target, the escorts are needlessly going in harms way. If the
|
|
# strike flight needs multiple passes, the escorts may leave before the
|
|
# escorted aircraft do.
|
|
#
|
|
# Another possible option would be to use Search Then Engage for join ->
|
|
# ingress and egress -> split, but use a Search Then Engage in Zone task
|
|
# for the target area that is set to end on a flag flip that occurs when
|
|
# the strike aircraft finish their attack task.
