Handling categories
Notes can be grouped into categories, which can be used to filter notes, or to give them different icons for an easier visualisation.
The Note Categories index
Inside the notes folder (specified in Project Settings), a ScriptableObject of type Note Categories is automatically created when first launching the tool.
This SO acts as an index of the categories that notes can belong to. For each category, you can assign a name and an icon.
Category icons
Each category icon will be displayed in the Scene View for all notes belonging to that category. You can assign any Texture2D contained in the project as an icon.
There are about 20 icons provided by default in different colours, and a .psd file that can be used as a template for creating new icons in the same style.
They are found in 📁 Packages/io.continis.scene-notes/UI/Images/NoteIcons_Category
Icons are only used if the Icon Displays setting in Project Settings is set to Categories. If your setting is to display icons for State, you can ignore the icons in the index.
The Categories Overlay
When you choose that note icons display their category, it can be easy to lose track of "which colour represents which category". For this, you can use the Categories Overlay to act as a legend.
The Categories Overlay can be opened by either hovering on the Scene View and pressing the ` key (the one next to Shift, on a British keyboard), or clicking on the three vertical dots menu at the top-right corner of the Scene View and selecting Overlays Menu, and then Categories Overlay.
The overlay also contains a button that acts as a shortcut to the Note Categories index, so you can quickly change them or edit their icons.
