UltiUnreal Writable Table is a database identical to the Unreal Datatable, but it allows you to save data and archive it in a JSON file. This is possible via blueprints with nodes or by directly modifying the associated JSON file. This plugin is designed for runtime: you can add, modify, or delete rows during execution, then save/load the table as JSON to disk, without coding a complete backup system.
Key features:
Runtime editable DataTable (rows add/update/remove)
JSON saving/loading
Atomic writing (prevents "broken" JSON files in case of a crash)
Optional auto-save with debounce
"Do not save if unchanged" option
Automatic backups (mini versioning) — by default, keeps the last two backups
Flexible paths: Saved from the project, project folder, or absolute path
Supported types (JSON) :
Bool, int32/int64, float, String, Name, Text (compatible with WRC object form), enums, asset references via path, Vector/Rotator/Transform, LinearColor, DateTime.
Nodes for:
checking/searching rows, setting/getting rows via struct, deleting by name/prefix/contains, clearing tables, reloading/merging from disk, setup nodes: JSON name, location, debounce, number of backups.
This plugin does not require the installation of any other plugins.
