* Helicopter waypoint altitude configurable Added a new option in Settings: Helicopter waypoint altitude (feet AGL). It sets the waypoint altitude for helicopters in feet AGL. In campaigns in more mountainous areas, you might want to increase this setting to avoid the AI flying into the terrain. * black? * Distinguish cruise/combat altitudes for helicopters Also includes a refactor for WaypointBuilder so it doesn't need a coalition. It can already reference the coalition from the flight. * Update changelog.md --------- Co-authored-by: Raffson <Raffson@users.noreply.github.com>
