# Tweak Inline Records

## Summary

## What are inline records?

{% hint style="info" %}
**TL;DR:** The names are generated at compile-time with every patch, so the order may change. Don't use them, rather create a full copy.
{% endhint %}

Sometimes, you will come across records with names like `Items.Preset_Overture_River_inline0`. That tells us exactly nothing, so what are they?

As we have learned in [How to YAML: Tweak modding basics](/cyberpunk-2077-modding/for-mod-creators-theory/core-mods-explained/tweakxl/tweakxl-changing-game-records/how-to-yaml-tweak-modding-basics.md) -> [How to YAML: Tweak modding basics](/cyberpunk-2077-modding/for-mod-creators-theory/core-mods-explained/tweakxl/tweakxl-changing-game-records/how-to-yaml-tweak-modding-basics.md#records), it is possible to nest records like Russian dolls. Inline records are exactly that: nested records, which are not defined anywhere but in the context that uses them.

{% hint style="success" %}
[Browsing the tweak database](/cyberpunk-2077-modding/for-mod-creators-theory/tweaks/tweaks/browsing-the-tweak-database.md)contains the full intel on how to find your way around.
{% endhint %}

Let's take a quick look. This is the tweak as read from the Tweak DB:

You can use Wolvenkit's [Tweak Browser](https://wiki.redmodding.org/wolvenkit/wolvenkit-app/editor/tweak-browser) to take a look at the properties:

If you want to use these effectors, you should define a copy in your yaml.

## **Safely modifying inline records**

{% hint style="danger" %}
If you modify a record (e.g. `VehicleStatPreset.BaseCar`) or one of its properties, then all records **inheriting** from it will be affected.

To learn how to avoid that, just keep reading.
{% endhint %}

Let's assume that we want to tweak the Hellhound's vehicle health. Here is the record:

<figure><img src="/files/nqKdhGMgreKpngPuNUpN" alt=""><figcaption></figcaption></figure>

As you can see, its health is based on the **shared record** `VehicleStatPreset.BaseCar_inline0`.

If you modify it directly, it will change the health of all vehicles. Therefore, to make changes, a new record must be created. You can see `VehicleStatPreset.BaseCar` in the statmodifierGroups, and `VehicleStatPreset.BaseCar_inline0 in its statModifiers:`

```yaml
Vehicle.v_standard3_militech_hellhound:
  statModifierGroups:
    - VehicleStatPreset.BaseCar
```

To make the change, create a new `VehicleStatPreset.Octant` to replace `VehicleStatPreset.BaseCar`:

```yaml
Vehicle.av_zetatech_octant_dav_dummy:
  statModifierGroups:
    - VehicleStatPreset.Octant
    - VehicleStatPreset.Strong 
```

Next, **define** `VehicleStatPreset.Octant`. This record will have `VehicleStatPreset.Octant_inline0` in its stat modifiers:

{% tabs %}
{% tab title="inherit from $base" %}
When inheriting a new base, you only need to include the information that is actually different:

```yaml
VehicleStatPreset.Octant:
  $base: VehicleStatPreset.BaseCar
  statModifiers:
    - !append-once VehicleStatPreset.Octant_inline0
```

{% endtab %}

{% tab title="define a $type" %}
When defining a new type, you need to include all information:

```yaml
VehicleStatPreset.Octant:
  $type: gamedataStatModifierGroup_Record
  drawBasedOnStatType: False
  optimiseCombinedModifiers: False
  saveBasedOnStatType: False
  statModsLimit: -1
  relatedModifierGroups: []
  statModifiers:
    - VehicleStatPreset.Octant_inline0         # this is the change
    - VehicleStatPreset.BaseCar_inline1
    - BaseStats.BaseAudioStimRangeMultiplier
    - BaseStats.BaseVisualStimRangeMultiplier 
```

{% endtab %}
{% endtabs %}

Finally, modify the value itself:

```yaml
VehicleStatPreset.Octant_inline0.value: 7600
```

This way, it won't affect other vehicles and you can still modify it.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://wiki.redmodding.org/cyberpunk-2077-modding/for-mod-creators-theory/tweaks/tweak-inline-records.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
