This tool generates .xnb font files for Terraria, can be used to create custom fonts for resource packs.

DynamicSpriteFontGenerator is a CLI app. However, rrryutaro made a fork with simple UI to make it more accessible.

Explanation for what each .xnb file does:

- Combat_Text: The text that appears on landing a hit;

- Combat_Crit: The text that appears on landing a critical. Should be a step larger, possibly bold or italic;

- Death_Text: Death message, Title Screen options;

- Item_Stack: Stack digits, Keybind UI options;

- Mouse_Text: Everything else.
