How do I change font colour in code (Godot 3) (Solved) (sopuli.xyz)

I want to create a "gradual colour change" effect in Godot.

eg: some_set_font_color_func(Color8(255,n,n) where n gradually decreases to make the text fade from white to red.

I can't figure out what function I would use in place of some_set_font_color_func to change a font's colour.

Godot themes are somewhat confusing. Given some var var UI:control how would I set the colour of any font(s) contained within that node?

Me: "I don't really understand shaders, and I've already tried to create a theme. Could you just explain set_color with examples of what name and theme_type may be in case that helps?"

Certainly! I apologize for any confusion. In Godot, the set_color function is typically used to modify the colors of various theme elements. To use set_color, you need to provide the name and theme_type parameters, which specify the theme element you want to modify.

Here's a brief explanation:

  • name: The name of the theme property you want to modify. This could be the name of a color property in the theme.
  • theme_type: The type of theme you are modifying. It could be one of the predefined theme types like Control, Button, etc.

Unfortunately, as of my last knowledge update in January 2022, Godot's documentation on theme names and theme types is not exhaustive, and it might have evolved since then. Therefore, you might need to refer to the official Godot documentation or experiment in the editor to find the specific names and types you need.

Here's a generic example using set_color:

# Assuming 'UI' is your Control node
UI.set_color("font_color", "Label", Color(1.0, 0.5, 0.5))  # Example values, adjust as needed

In this example:

  • "font_color" is the name of the color property you want to modify.
  • "Label" is the theme type, specifying that you want to modify the font color of a Label.

To find the specific names and types, you may want to experiment with the Godot editor or refer to the Godot documentation. Keep in mind that themes can be a bit finicky, and not all properties may be easily accessible or adjustable programmatically. If themes prove too cumbersome, consider other approaches like shaders or direct color manipulation.

Me: "Don't worry. Godot 3 is an older LTS version, so it's documentation probably won't get update much. Jan 2022 knowledge is fine."

Me: "That solved my problem. Thank you."

You're welcome! I'm glad to hear that it solved your problem. If you have any more questions or run into any issues in the future, feel free to reach out. Happy coding in Godot!
