Doors coords are from counting either Horizontal or Vertical walls from 0,0 in the top left. The recent beacon info has some unknown length variation so I can't reliably get at those obvious strings. I haven't yet found the sector map stuff.

ComaToes commented 12 years ago

Looks good. We can add this as an extra tab if a continue.sav is found in the same directory as the prof.sav

ComaToes commented 12 years ago

I have established that the sector map is generated based on the int at location 2079 in your example (7F6B 0000). Changing the value of this radically alters the map. My guess is that it's used as a seed to a random number generator which is then used to generate the layout.

Vhati commented 12 years ago

a seed to a random number generator

Gah. Well, if it turns out sensor data isn't parsable, there's still the possibility of a "randomize map" button. :P

The first big mystery block (977-1221 above) describes all possible systems in a fixed order: Shields, Engines, Oxygen, Weapons, Drone Ctrl, Medbay, Pilot, Sensors, Doors, Teleporter, Cloaking, Artillery.

First, an int describing reserve capacity. Thereafter, each system begins with capacity (4 bytes). If it's zero, the system is truncated. If capacity is non-zero, next comes used power (4 bytes), which is why there are pairs of similar values for powered up systems. Then there's 20 bytes of weird non-int stuff.

So... systems that are present are 28 bytes. Systems that aren't are 4 bytes.

A smaller block, (2024-2028 above, appearing right after weapons) is a count of drones, which in this example was 0. They have a bunch of int attributes I haven't nailed down yet.

Vhati commented 12 years ago

I just looked at an escort-quest ship while it was still on-screen. Stored exactly like the player's, except using an id from autoBlueprints.xml. So I'll be moving [blueprint/name/layout through augments] out of SavedGameState into a generic ShipState class.

The ship I saw was at the end of the file, so I don't know if it was after the beacons, or part of the final one.

ComaToes commented 12 years ago

I've added parsing for cargo, beacons and sector data. The ship data at the end of the file is there if you save while there's another ship at the current beacon (e.g. if you accept surrender or avoid combat). It's not a part of the beacon list.

Vhati commented 12 years ago

Something's not quite right about door indexing. Engi cruiser 2's doors aren't all in ShipLayout.txt order.

Vhati commented 12 years ago

Okay doors are fixed in commit 870728e . The game sorts doors at runtime prior to saving, same relative order, except vacuum-adjacent doors are moved to the end.

Vhati commented 12 years ago

So that's what the 'close' button does. :P

Vhati commented 12 years ago

Good timing with v11. I was in the middle of writing commit 77cdbda which edits almost every crew field. That'll need some corner-case testing because of the goofy way FTL handles races and flags.

Vhati commented 12 years ago

When v12 comes out, screenshots would be nice.

Engi B with drones deployed, a couple rooms open to vacuum, a varied crew, and one crew being edited.
Some other ship with a weapon being changed to Boss Missile... >:D
A nightmare scenario with intruders, breaches, and fires...

Vhati commented 12 years ago

Editing the forum thread's description to mention saved game editing would be good too.
