DynamicFont

Inherits: Font < Resource < Reference < Object

DynamicFont renders vector font files at runtime.

Description

DynamicFont renders vector font files (such as TTF or OTF) dynamically at runtime instead of using a prerendered texture atlas like BitmapFont. This trades the faster loading time of BitmapFonts for the ability to change font parameters like size and spacing during runtime. DynamicFontData is used for referencing the font file paths. DynamicFont also supports defining one or more fallbacks fonts, which will be used when displaying a character not supported by the main font.

DynamicFont uses the FreeType library for rasterization.

var dynamic_font = DynamicFont.new()
dynamic_font.font_data = load("res://BarlowCondensed-Bold.ttf")
dynamic_font.size = 64
$"Label".set("custom_fonts/font", dynamic_font)

Note: DynamicFont doesn’t support features such as right-to-left typesetting, ligatures, text shaping, variable fonts and optional font features yet. If you wish to “bake” an optional font feature into a TTF font file, you can use FontForge to do so. In FontForge, use File > Generate Fonts, click Options, choose the desired features then generate the font.

Enumerations

enum SpacingType:

  • SPACING_TOP = 0 — Spacing at the top.
  • SPACING_BOTTOM = 1 — Spacing at the bottom.
  • SPACING_CHAR = 2 — Character spacing.
  • SPACING_SPACE = 3 — Space spacing.

Property Descriptions

  • int extra_spacing_bottom
Default 0
Setter set_spacing(value)
Getter get_spacing()

Extra spacing at the bottom in pixels.

  • int extra_spacing_char
Default 0
Setter set_spacing(value)
Getter get_spacing()

Extra character spacing in pixels.

  • int extra_spacing_space
Default 0
Setter set_spacing(value)
Getter get_spacing()

Extra space spacing in pixels.

  • int extra_spacing_top
Default 0
Setter set_spacing(value)
Getter get_spacing()

Extra spacing at the top in pixels.

Setter set_font_data(value)
Getter get_font_data()

The font data.

Default Color( 1, 1, 1, 1 )
Setter set_outline_color(value)
Getter get_outline_color()

The font outline’s color.

Note: It’s recommended to leave this at the default value so that you can adjust it in individual controls. For example, if the outline is made black here, it won’t be possible to change its color using a Label’s font outline modulate theme item.

  • int outline_size
Default 0
Setter set_outline_size(value)
Getter get_outline_size()

The font outline’s thickness in pixels (not relative to the font size).

Default 16
Setter set_size(value)
Getter get_size()

The font size in pixels.

Default false
Setter set_use_filter(value)
Getter get_use_filter()

If true, filtering is used. This makes the font blurry instead of pixelated when scaling it if font oversampling is disabled or ineffective. It’s recommended to enable this when using the font in a control whose size changes over time, unless a pixel art aesthetic is desired.

Default false
Setter set_use_mipmaps(value)
Getter get_use_mipmaps()

If true, mipmapping is used. This improves the font’s appearance when downscaling it if font oversampling is disabled or ineffective.

Method Descriptions

Adds a fallback font.

Returns the fallback font at index idx.

  • int get_fallback_count ( ) const

Returns the number of fallback fonts.

  • int get_spacing ( int type ) const

Returns the spacing for the given type (see SpacingType).

  • void remove_fallback ( int idx )

Removes the fallback font at index idx.

Sets the fallback font at index idx.

  • void set_spacing ( int type, int value )

Sets the spacing for type (see SpacingType) to value in pixels (not relative to the font size).
