Add option to fast forward to first contact.

Browse Source 
This is the first step in a larger project to add play/pause buttons to
the Liberation UI so the mission can be generated at any point.
docs/design/turnless.md describes the plan.

This adds an option to fast forward the turn to first contact before
generating the mission. None of that is reflected in the UI (for now),
but the miz will be generated with many flights in the air.

For now "first contact" means as soon as any flight reaches its IP. I'll
follow up to add threat checking so that air-to-air combat also triggers
this, as will entering a SAM's threat zone.

This also includes an option to halt fast-forward whenever a player
flight reaches a certain mission-prep phase. This can be used to avoid
fast forwarding past the player's startup time, taxi time, or takeoff
time. By default this option is disabled so player aircraft may start in
the air (possibly even at their IP if they're the first mission to reach
IP).

Fuel states do not currently account for distance traveled during fast
forward. That will come later.

# Turnless Campaign
This outlines a path for us converting Liberation from turn based into a
turnless campaign game like BMS.
## Hard problems
### We can't simulate combat
We can't feasibly simulate the details of combat, nor can we generate a mission
mid-engagement. The mission editor does not support generating aircraft
mid-maneuver, or with any SA.
To avoid that problem, instead of simulating the combat we put the group in a
"freeze" at the moment the engagement begins. Any frozen groups are spawned
wherever they were frozen so simulation can be deferred to DCS. Each freeze will
have a deadline for completion, at which point a simple strength-based
autoresolve will take place.
After a frozen engagement is resolved (whether in sim or automatically), if the
mission objective has not been achieved a mission abort will be evaluated.
### We don't know where the roads are
We don't know where the in-game roads are, so we can't precisely simulate the
location of convoys as they move, nor the amount of time they will take to move
between bases.
Time can be solved by just having the campaign designer encode the travel time
in the campaign. The ME will estimate it for them so it’s simple to do. Spawn
locations cannot be made precise, but we can have campaign designers define
several waypoints along the route and spawn the convoy at the most appropriate
one.
### SAM engagement zones are huge
The large threat zone of many SAMs would cause most of the map to be a frozen
engagement.
To avoid that, SAMs will not cause frozen engagements, but will be simulated at
a basic level. Each SAM will track a group, and when in range will periodically
“shoot”, and those shots will have a chance to kill an aircraft in the targeted
group.
## Systems that need to change
### AI Commander
Theater state tracking for the HTN becomes much more complicated since it needs
to always be able to replan based on pending plans. This shouldn't be too bad
since RndName's PR did similar and the plan to continue that should work here.
The commander needs to learn to abort missions that are no longer viable.
### Transports
With turns gone, transports can longer move one link per turn. See the entry in
"hard problems" above. To begin with we can pick an arbitrary time per link and
just always spawn the transport at the origin regardless of where they ought to
be.
### Turn based systems
A number of systems that act in a number of turns become time based:
- Runway repair
- Unit delivery
- Weather changes
- Pilot replenishment
- Income
Procurement could be made simpler if we do away with cash in favor of fixed
replenishment rates.
### Front line advancement
Front line combat is happening continuously so we need to simulate its movement
and losses on the front line.
### Mission generation
The mission generator needs to be able to generate aircraft in specific
locations, with partial fuel, and possibly with some weapons expended.
### Mission result processing
Last known positions need to be recorded, as do weapon inventory and fuel
states.
### UI
Frozen combats need to be immutable to the player.
Missions in progress need to be made cancelable.
The map needs to show the locations of in-progress missions, including frozen
engagements.
There needs to be a UI to examine frozen engagements.
## Roadmap
This roadmap is ordered so that we can attempt to make this change in phases
that may take more than a single release. It is not focused on providing the
best gameplay experience ASAP, but on being able to approach this gradually
rather than freezing all other development or branching and a painful merge.
### Front-line progress rework
Add auto-resolve for the front line, adjust progress estimates based on stances
and not just kills (an enemy in retreat is less likely to be killed, but still
gives up ground).
### Add play from first-contact option
Add simulation of the mission from the start of the turn up to the first
engagement. Generate the mission from that point.
### Add fuel expenditure estimation for travel to start location
Adjust fuel quantities at the start of the mission to account for travel.
### Add UI to display simulation to first contact
Before removing turns, add play/pause buttons to the game that will simulate the
mission up to the first engagement. Once play is pressed no changes may be made
to the ATO.
When the turn ends it behaves like the normal end of turn. The ATO is reset and
the new turn is planned.
### Add mission abort option for players
Add the option to abort flight and packages for players. The AI won’t use this
yet but it will be needed once engagement simulation is added.
### Add simulation for frozen combats
Allows play to proceed through engagements. The AI will abort missions that are
unlikely to succeed after each combat is resolved.
### Estimate fuel/weapon use simulation for frozen combats
Improve behavior for groups that have completed an auto-resolved combat by
estimating their fuel and ammo use. This could be used to check if the mission
should be aborted.
### Add player options to create new packages after pressing play
Allow players to create new flights as the mission simulates. This would be the
most effective way to add intercept missions.
### Make planning real-time
Make the AI planner periodically reevaluate missions to add to the ATO. It will
still plan as many missions as possible up front so that the DCS side of the
mission can run as long as possible, but it could make use of aircraft that had
aborted or returned.
### Time-based systems instead of turn based
Move the systems that are currently based on turns to be based on duration. Each
turn is assumed to be six hours since there are four turns in a day.
### Time between turns based on mission duration
Change the turn duration to be based on the length of the mission played.
### Track end positions of aircraft, remove turns
If we can track the status of missions after the simulation ends we can continue
where we left off. Do that, and remove the concept of turns.
### Track ammo/fuel status of aircraft at the end of the mission
Improve post-simulation realism by tracking the ammunition and fuel spent.
### Add turnaround times for landed aircraft
Once aircraft returning from a mission land, a timer starts to track the
turnaround time before they'll be ready to redeploy as opposed to being instant.

We cannot spawn aircraft mid-taxi, so when the simulated state is near the end
of a long taxi period the aircraft will be spawned in their parking spot. This
could lead to problems but that's what loiter points are for. The other pre-
flight states have the same problem but are much shorter and more easily covered
by the loiter time. Player flights that are spawned near the end of their cold
start have the biggest problem but players are able to cut corners to make up
for lost time.
Aircraft that are already in the air will be spawned at their estimated
location, speed, and altitude based on their flight plan.
