void asw::util::clear_text_size_cache

int asw::util::get_font_height

(

const asw::Font &

font

)

Get the height of a line of text in a font.

Parameters

font	Font to use

Returns

Line height in pixels, 0 if the font is not loaded

Definition at line 106 of file util.cpp.

get_text_size()

asw::Vec2< int > asw::util::get_text_size	(	const asw::Font &	font,
		std::string_view	text )

Get text size.

Parameters

font	Font to use
text	Text to get size of

Returns

Size as Vec2

Definition at line 81 of file util.cpp.

get_texture_size()

asw::Vec2< float > asw::util::get_texture_size

(

const asw::Texture &

tex

)

Get texture size.

Parameters

tex	Texture to get size of

Returns

Size as Vec2

Definition at line 74 of file util.cpp.

lerp()

template<typename T >

T asw::util::lerp	(	const T &	a,
		const T &	b,
		float	t )

Lerp between two values.

Parameters

a	Start value
b	End value
t	Interpolation value (0-1)

Returns

Interpolated value

Definition at line 73 of file util.h.

open_url()

bool asw::util::open_url

(

const std::string &

url

)

Open a web page in the player's browser, e.g. a login or store page. Web builds open it in a new tab.
