Question 1

How do I set up live preview in ThemeGen?

Accepted Answer

Enable the 'ThemeGen Save Sync' plugin in Project Settings and add const UPDATE_ON_SAVE = true to your theme script. This automatically regenerates the theme on save, providing instant feedback in the editor without manual runs.

Question 2

ThemeGen vs Godot's built-in theme editor: which should I use?

Accepted Answer

Use ThemeGen for complex projects needing code-based reuse, inheritance, and variants. Stick with Godot's editor for simple, visual theming or when non-coders are involved, as ThemeGen requires GDScript proficiency and setup time.

Question 3

Can ThemeGen be used with custom Godot nodes?

Accepted Answer

Yes, through define_style_variant for node variations and accessing current_theme for custom properties. This allows programmatic styling of any node type, but requires manual definition in GDScript.

Question 4

How to create dark and light themes with ThemeGen?

Accepted Answer

Define multiple setup functions like setup_light_theme() and setup_dark_theme() in your script, setting different color variables and save paths. ThemeGen automatically generates separate .tres files for each variant on script execution.

Question 5

What are the shortcut methods in ThemeGen for repetitive properties?

Accepted Answer

ThemeGen provides methods like border_width(), corner_radius(), and expand_margins() that use an underscore suffix to merge sub-dictionaries, reducing boilerplate for properties such as border widths across all sides.

Question 6

Does ThemeGen work with Godot 3.x or C#?

Accepted Answer

No, ThemeGen is specifically for Godot 4.x and GDScript only, as indicated in the README badges. For Godot 3 or C# projects, you'll need alternative theming solutions or manual approaches.
