Member Function Documentation

init()

void text::init ( )

static

Initialize the text subsystem.

This method initializes the text subsystem by loading the shader, the VAO, and the VBO. The shader is loaded from the file text.vs and text.fs, and the VAO and VBO are created using the data from the characters map.

Note: opengl context must be created before calling this method.

Definition at line 41 of file text.cpp.

load()

void text::load ( std::string font_name, unsigned int font_size )

static

Load a font.

This method loads a font from the given file and size. The font is loaded using the FreeType library, and the characters are stored in the characters map.

Parameters

font_name	Name of the font file
font_size	Size of the font

render_text()

void text::render_text ( std::string text, float x, float y, float scale, glm::vec3 color )

static

Render text.

This method renders the given text on the screen at the given position, with the given scale and color. The text is rendered using the shader, VAO, and VBO that are initialized in the Init method.

Parameters

text	Text to render
x	X position of the text
y	Y position of the text
scale	Scale of the text
color	Color of the text
