Ship Log

Understanding Ship Logs

First thing’s first, I’ll define some terminology regarding ship logs in the game, and how ship logs are structured.

Entries

An entry is a card you see in rumor mode, it represents a specific area or concept in the game, such as Timber Hearth’s village or the southern observatory on Brittle Hollow.
An entry is split up into facts, a fact can either be a rumor fact or an explore fact.

entryExample In red you can see an entry, in green you can see the entry’s facts

Curiosities

Curiosities are entries that represent big ideas in the story, such as the ATP or the OPC.
Non-curiosity entries have a Curiosity attribute that can be set to make the color of that entry match the color of the curiosity (Like how everything regarding the Vessel is red)

curiosityExample The Ash Twin Project is an example of a curiosity (internally it’s called TIME_LOOP)

Child Entries

Entries can be children of other entries, meaning they’ll be smaller.

childEntryExample The murals at the old settlement on Brittle Hollow are examples of child entries

Rumor Facts

A rumor fact represents the information you might hear about a specific area or concept, usually, you get these through dialogue or maybe by observing a faraway planet.

Explore Facts

Explore facts represent the information you learn about a specific area or concept.

The XML

Now that we know some terminology, let’s get into how the XML works.
Every planet in the ship log is represented by a single XML file, you can see this if you use the unity explorer mod and navigate to ShipLogManager.

Example File

<!-- Example File -->
<!-- All files must have "AstroObjectEntry" as their root element, the xmlns:xsi=... and xsi:noNamespaceSchemaLocation=... is optional but heavily encouraged to reduce errors -->
<AstroObjectEntry xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:noNamespaceSchemaLocation="https://raw.githubusercontent.com/Outer-Wilds-New-Horizons/new-horizons/main/NewHorizons/Schemas/shiplog_schema.xsd">

        <Curiosity>EXAMPLE_ENTRY</Curiosity> <!-- The curiosity this entry belongs to (optional) in this case, it belongs to itself -->
        <IsCuriosity/> <!-- Marks this entry as a curiosity, makes it bigger in rumor mode and allows custom colors -->

            <Text>Example Explore Fact 3</Text>
        </ExploreFact>
    </Entry>
</AstroObjectEntry>

Using The Schema

In the example XML, you may notice something like xsi:noNamespaceSchemaLocation at the top, this tells whatever editor you’re using that the file at that link is the schema. The game simply ignores this though, so it won’t be able to catch errors at runtime.
Some editors may require you to Trust the workspace to use the schema file. Doing this varies per-editor, and you may also have to right-click the link and click download.

Loading The File

You can load your XML file to your planet by doing adding the following to your planet’s config

{
    "ShipLog": {
        "xmlFile": "planets/example.xml"
    }
}

Rumor Mode Options

Entry Layout

By default, entries in rumor mode are laid out by rows, where each row is one planet. This will not make for a perfect layout, so you can use the entryPositions property in your star system config to change them.
For example, if I want to change an entry with the ID of EXAMPLE_ENTRY and another with the ID of EXAMPLE_ENTRY_2:

{
    "entryPositions": [
        {
            "id": "EXAMPLE_ENTRY",
            "position": {
                "x": 100,
                "y": 200
            }
        },
        {
            "id": "EXAMPLE_ENTRY_2",
            "position": {
                "x": 200,
                "y": 100
            }
        }
    ]
}

To help with this, download the unity explorer mod and manually position entries (they’re located under Ship_Body/Module_Cabin/Systems_Cabin/ShipLogPivot/ShipLog/ShipLogPivot/ShipLogCanvas/MapMode/ScaleRoot/PanRoot), then simply use the dev tools to dump all the entries to a json string you can copy and paste into your config.

autoDetectiveMode A set of entries laid out with auto mode

Images

Custom entry images are a bit different from other custom images, instead of pointing to each file for each entry, you point to a folder:

{
    "ShipLog": {
        "xmlFile": "planets/example.xml",
        "spriteFolder": "planets/example_planet_entry_sprites/"
    }
}

Each file is in this folder is then named the ID of each entry.
for example, EXAMPLE_ENTRY’s file would be named EXAMPLE_ENTRY.png.
you set alternate sprites by making a file with the entry’s ID and _ALT at the end, so EXAMPLE_ENTRY’s alt image would be EXAMPLE_ENTRY_ALT.png.

Curiosity Colors

Colors for each curiosity is given in a list within the star system config, so if I wanted the curiosity EXAMPLE_ENTRY to have a color of blue:

{
    "curiosities": [
        {
            "id": "EXAMPLE_ENTRY",
            "color": {
                "r": 0,
                "g": 0,
                "b": 100,
                "a": 255
            },
            "highlightColor": {
                "r": 0,
                "g": 1,
                "b": 255,
                "a": 255
            }
        }
    ]
}

curiosityColorChange The curiosity’s color is changed to blue

Map Mode Options

Layout

Layout in map mode can be handled in two different ways, either manual or automatic, if you try to mix them you’ll get an error.
Also, adding planets to the vanilla solar system requires you to use manual layout.

Automatic Layout

In automatic layout, each planet that orbits the center of the solar system is put in a row, then, each planet orbiting those planets are put in a column, then, each planet orbiting those planets are put in a row for as many planets there are. The order of each planet is determined by their semi-major axis, if two planets have the same semi-major axis then they’re sorted by order loaded in.

autoMapMode An example system laid out with auto mode

Offset

The offset option lets you adjust a planet’s offset from the last planet.

{
    "ShipLog": {
        "xmlFile": "planets/example.xml",
        "mapMode": {
            "offset": -5.0
        }
    }
}

For example, this offsets example planet in map mode by -5 units.

Manual Layout

The manual layout is a lot more involved than automatic but offers much greater freedom.
Manual layout requires you to fill out both manualPosition and manualNavigationPosition

Manual Position

Setting the manualPosition option in the mapMode object sets its position (if manual position isn’t set, it assumes the planet is using automatic mode)

{
    "ShipLog": {
        "xmlFile": "planets/example.xml",
        "mapMode": {
            "manualPosition": {
                "x": 0,
                "y": 500
            },
            "manualNavigationPosition": {}
        }
    }
}

This setting tells Outer Wilds how to handle navigation for this object, the x and y values correlate to the row and column of this planet. For example, the sun station is at navigationPosition (0, 1) as it is in the first column on the second row (you can’t select the sun, so it doesn’t have a row or column). So, by making a navigation position of:

{
    "ShipLog": {
        "xmlFile": "planets/example.xml",
        "mapMode": {
            "manualPosition": {
                "x": 0,
                "y": 500
            },
            "manualNavigationPosition": {
                "x": 1,
                "y": 1
            }
        }
    }
}

We say this planet is to the right of the sun station (putting in a position that is already occupied will override what is in that position).

navigationIndices

Overriding Vanilla Planets

You can also move vanilla planets by creating configs with their names and changing their manualPosition and manualNavigationPosition

Settings for both layouts

These settings can be used for both type of layouts

Sprites

Reveal Sprite

A path to the sprite to show for when the planet is revealed

Outline Sprite

A path to an outline to show for when the planet is undiscovered

Invisible When Hidden

Settings invisibleWhenHidden to true makes the planet entirely invisible when not discovered instead of showing an outline.

Scale

How much to scale this planet in the map mode screen (you may have to change offset to compensate)

{
    "ShipLog": {
        "xmlFile": "planets/example.xml",
        "mapMode": {
            "scale": 0.5
        }
    }
}

Shrinks the planet by one half

Remove

Don’t include this planet in map mode at all, simply ignore it

Details

Details are images that go on top of a planet in map mode, and changes states with the planet (like the sand funnel between Ash Twin and Ember Twin)

{
    "ShipLog": {
        "xmlFile": "planets/example.xml",
        "mapMode": {
            "details": [
                {
                    "revealedSprite": "planets/assets/image.png",
                    "outlineSprite": "planets/assets/outline.png",
                    "invisibleWhenHidden": true,
                    "rotation": 45,
                    "scale": {
                        "x": 0.2,
                        "y": 0.2
                    },
                    "position": {
                        "x": 20,
                        "y": 10
                    }
                }
            ]
        }
    }
}

As you can see, they have similar properties to planets, with the addition of rotation

Revealing Facts

Of course, having a custom ship log is neat and all, but what use is it if the player can’t unlock it?

Initial Reveal

You can set facts to reveal as soon as the player enters the system by adding the initialReveal property to your star system config

{
    "initialReveal": ["EXAMPLE_RUMOR_FACT"]
}

Signal Discovery

You can set a fact to reveal as soon as a signal is identified by editing the signal’s reveals attribute

{
    "Props": {
        "signals": [
            {
                "frequency": "Quantum",
                "name": "Quantum Planet",
                "audio": "OW_QuantumSignal",
                "sourceRadius": 1000,
                "reveals": "EXAMPLE_EXPLORE_FACT"
            }
        ]
    }
}

Dialogue

You can set a fact to reveal in dialogue with the <RevealFacts> tag

<!-- Example Dialogue -->
<DialogueNode>
    <Name>1</Name>
    <Dialogue>
        <Page>Check your ship log!</Page>
    </Dialogue>
    <RevealFacts>
        <FactID>EXAMPLE_EXPLORE_FACT</FactID>
    </RevealFacts>

    <DialogueOptionsList>
        <!-- ... -->
    </DialogueOptionsList>
</DialogueNode>

Reveal Volumes

Reveal volumes are triggers/colliders in the world that can unlock facts from a variety of actions.
Reveal volumes are specified in the Volumes module, its key is revealVolumes.

Position

The position of the reveal volume, relative to this planet’s center

Radius

How big the collider is (use the collider visualizer mod for help)

Reveals

A list of facts this volume reveals

Reveal On

Can be any of the following:

Enter

When the player or probe enters the trigger, reveal the facts

Observe

When the player observes the trigger, reveal the facts

Snapshot

When the player takes a picture of the trigger, reveal the facts

Max Distance

Can only be used if revealOn is set to Observe or Snapshot, the max distance away the player can be and still be able to trigger the reveal

Max Angle

Can only be used if revealOn is set to Observe, the max angle the player can be looking away from the trigger to still trigger the reveal

Example

{
    "Volumes": {
        "revealVolumes": [
            {
                "position": {
                    "x": -55.65454,
                    "y": 83.1335,
                    "z": 2.7004
                },
                "revealOn": "snapshot",
                "reveals": ["EXAMPLE_EXPLORE_FACT", "EXAMPLE_EXPLORE_FACT_2"],
                "radius": 5.0
            }
        ]
    }
}

Setting Entry Locations

Entry locations are the “Mark On HUD” option you see when in map mode, this allows the player to go back to where they were in the event of the big funny.
Adding an entry location is similar to adding a Reveal Volume:

{
    "Props": {
        "entryLocation": [
            {
                "id": "EXAMPLE_ENTRY",
                "position": {
                    "x": -55.65454,
                    "y": 83.1335,
                    "z": 2.7004
                },
                "cloaked": false
            }
        ]
    }
}

entryLocationExample

Extending Base Game Entries

You can add new facts and sub-entries to existing ship log entries by adding a dummy entry to your ship log XML file with the same ID as an existing entry. Any facts and sub-entries will be applied to the existing entry. For example, to extend the “Village” entry on Timber Hearth (which has the internal ID “TH_VILLAGE”):

<AstroObjectEntry xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="https://raw.githubusercontent.com/Outer-Wilds-New-Horizons/new-horizons/main/NewHorizons/Schemas/shiplog_schema.xsd">
    <ID>TIMBER_HEARTH</ID>
    <Entry>
        <ID>TH_VILLAGE</ID>
        <ExploreFact>
            <ID>EXAMPLES_VILLAGE</ID>
            <Text>A lot of unfamiliar characters are hanging around the village now.</Text>
        </ExploreFact>
        <Entry>
            <ID>EXAMPLES_DREAM</ID>
            <Name>Wetrock Dream</Name>
            <ExploreFact>
                <ID>EXAMPLES_DREAM_EXPLORED</ID>
                <Text>I dreamed about Wetrock using a green campfire.</Text>
            </ExploreFact>
        </Entry>
    </Entry>
