Configuration

The engine configuration is stored in multiple scriptable object assets located at Assets/NaninovelData/Resources/Naninovel/Configuration folder. They are automatically generated when opening the corresponding configuration menus in the Unity editor for the first time.

Use Naninovel -> Configuration or Edit -> Project Settings -> Naninovel to access the configuration menu.

Notice, that all the configuration menus are supporting Unity's presets feature ↗. It could be useful to create several configuration presets when deploying to different target platforms (eg, mobile, standalone, consoles, etc).

It's possible to modify configuration objects at runtime, add new custom configurations and change the way the objects are accessed at runtime (eg, read configuration from JSON files stored on a remote host); see custom configuration guide for more information.

PropertyDefault ValueDescription
Override Objects LayerFalseWhether to assign a specific layer to all the engine objects. Engine's camera will use the layer for the culling mask. Use this to isolate Naninovel objects from being rendered by other cameras.
Objects Layer0When Override Objects Layer is enabled, the specified layer will be assigned to all the engine objects.
Async Exception Log TypeErrorLog type to use for UniTask-related exceptions.
Async InstantiationTrueWhether to use Object.InstantiateAsync for instantiating engine objects, which moves most associated work off the main thread. Keep enabled unless experiencing issues.

Record Separator
Annotation Prefix>Text character to insert before annotation lines to distinguish them for the localized text. Annotations are comments optionally added to the generated localization documents to provide additional context for the translators, such as author of the printed text messages, inlined commands and command lines containing localized parameters. Stub character is used to replace localized parts of such annotations, as they're duplicated on the next comment line containing the text to localize.

Resource Provider

PropertyDefault ValueDescription
Resource PolicyConservativeDictates when the resources are loaded and unloaded during script execution:
• Conservative — The default mode with balanced memory utilization. All the resources required for script execution are preloaded when starting the playback and unloaded when the script has finished playing. Scripts referenced in @gosub commands are preloaded as well. Additional scripts can be preloaded by using hold parameter of @goto command.
• Optimistic — All the resources required by the played script, as well all resources of all the scripts specified in @goto and @gosub commands are preloaded and not unloaded unless release parameter is specified in @goto command. This minimizes loading screens and allows smooth rollback, but requires manually specifying when the resources have to be unloaded, increasing risk of out of memory exceptions.
Remove ActorsTrueWhether to automatically remove unused actors (characters, backgrounds, text printers and choice handlers) when unloading script resources. Note, that even when enabled, it's still possible to remove actors manually with @remove commands at any time.
Log Resource LoadingFalseWhether to log resource un-/loading operations.
Enable Build ProcessingTrueWhether to register a custom build player handle to process the assets assigned as Naninovel resources.

Warning: In order for this setting to take effect, it's required to restart the Unity editor.
Use AddressablesTrueWhen the Addressable Asset System is installed, enabling this property will optimize asset processing step improving the build time.
Auto Build BundlesTrueWhether to automatically build the addressable asset bundles when building the player. Has no effect when Use Addressables is disabled.
Allow Addressable In EditorFalseWhether to use addressable provider in editor. Enable if you're manually exposing resources via addressable address instead of assigning them with Naninovel's resource managers. Be aware, that enabling this could cause issues when resources are assigned both in resources manager and registered with an addressable address and then renamed or duplicated.
Label By ScriptsTrueWhether to label all the Naninovel addressable assets by the scenario script path they're used in. When Bundle Mode is set to Pack Together By Label in the addressable group settings, will result in a more efficient bundle packing.

Note that script labels will be assigned to all the assets with 'Naninovel' label, which includes assets manually exposed to the addressable resource provider (w/o using the resource editor menus).
Group By CategoryFalseWhether to create an addressable group per Naninovel resource category: scripts, characters, audio, etc. When disabled, will use single Naninovel group for all the resources.
Extra LabelsNullAddressable provider will only work with assets, that have the assigned labels in addition to Naninovel label. Can be used to filter assets used by the engine based on custom criteria (eg, HD vs SD textures).
Local Root Path%DATA%/ResourcesPath root to use for the local resource provider. Can be an absolute path to the folder where the resources are located, or a relative path with one of the available origins:
• %DATA% — Game data folder on the target device (UnityEngine.Application.dataPath).
• %PDATA% — Persistent data directory on the target device (UnityEngine.Application.persistentDataPath).
• %STREAM% — StreamingAssets folder (UnityEngine.Application.streamingAssetsPath).
• %SPECIAL{F}% — An OS special folder (where F is value from System.Environment.SpecialFolder).
Video Stream Extension.mp 4When streaming videos under WebGL (movies, video backgrounds), specify the extension of the video files.
Project Root PathNaninovelPath relative to Resources folders, under which the naninovel-specific assets are located.

Skip Time Scale10Time scale to use when in skip (fast-forward) mode.
Min Auto Play Delay1Minimum seconds to wait before executing next command while in auto play mode.
Complete On ContinueTrueWhether to instantly complete blocking (wait!) commands performed over time (eg, animations, hide/reveal, tint changes, etc) when Continue input is activated.
Show Debug On InitFalseWhether to show player debug window on engine initialization.
Wait By DefaultFalseWhether to wait the played commands when the wait parameter is not explicitly specified. Only applicable to the awaitable (asynchronous) commands.

WARNING: Don't enable in new projects, as this option is kept for backward compatibility and will be removed in the next release.
Show Loading UITrueWhether to show ILoadingUI while a script is pre-/loaded. Allows masking resource loading process with the loading screen.
Resolve ModeNearestThe mode in which script player handles missing playback spots when loading state. This may happen when player saved a game amidst a scenario script, which is then changed (eg, via a game update) and the saved playback spot (line and inline indexes) is no longer available.
• Nearest — Attempt to play from the nearest next spot; in case no next spots found (script was made shorter), start from nearest previous one. Most forgiving mode, but could cause an undefined behaviour.
• Restart — Start playing current script from start. Won't cause undefined behaviour in case all the state is local to scenario script, but player will have to re-play the script form the start.
• Error — Throw an error. Choose this option in case undefined behaviour is not acceptable.
