BitmapFont¶

Inherits: Font < Resource < Reference < Object

Renders text using fonts under the BMFont format.

Handles files with the .fnt extension.

Description¶

Renders text using *.fnt fonts containing texture atlases. Supports distance fields. For using vector font files like TTF directly, see DynamicFont.

Properties¶

float	ascent	`0.0`
bool	distance_field	`false`
BitmapFont	fallback
float	height	`1.0`

Methods¶

void	add_char ( int character, int texture, Rect2 rect, Vector2 align=Vector2( 0, 0 ), float advance=-1 )
void	add_kerning_pair ( int char_a, int char_b, int kerning )
void	add_texture ( Texture texture )
void	clear ( )
Error	create_from_fnt ( String path )
int	get_kerning_pair ( int char_a, int char_b ) const
Texture	get_texture ( int idx ) const
int	get_texture_count ( ) const

Property Descriptions¶

float ascent = 0.0

void set_ascent ( float value )
float get_ascent ( )

Ascent (number of pixels above the baseline).

bool distance_field = false

void set_distance_field_hint ( bool value )
bool is_distance_field_hint ( )

If true, distance field hint is enabled.

BitmapFont fallback

void set_fallback ( BitmapFont value )
BitmapFont get_fallback ( )

The fallback font.

float height = 1.0

void set_height ( float value )
float get_height ( )

Total font height (ascent plus descent) in pixels.

Method Descriptions¶

void add_char ( int character, int texture, Rect2 rect, Vector2 align=Vector2( 0, 0 ), float advance=-1 )

Adds a character to the font, where character is the Unicode value, texture is the texture index, rect is the region in the texture (in pixels!), align is the (optional) alignment for the character and advance is the (optional) advance.

void add_kerning_pair ( int char_a, int char_b, int kerning )

Adds a kerning pair to the BitmapFont as a difference. Kerning pairs are special cases where a typeface advance is determined by the next character.

void add_texture ( Texture texture )

Adds a texture to the BitmapFont.

void clear ( )

Clears all the font data and settings.

Error create_from_fnt ( String path )

Creates a BitmapFont from the *.fnt file at path.

int get_kerning_pair ( int char_a, int char_b ) const

Returns a kerning pair as a difference.

Texture get_texture ( int idx ) const

Returns the font atlas texture at index idx.

int get_texture_count ( ) const

Returns the number of textures in the BitmapFont atlas.
