begin_prepare_text

begin_prepare_text :: (font: *Dynamic_Font)

Starts a new run of prepared text, dropping what an earlier run gathered, glyphs and quads alike.

A run is built with begin_prepare_text, any number of append_prepare_text calls and end_prepare_text. After the end, font.current_quads holds one Font_Quad per glyph, so the layout can be looked at, and draw_prepared_text draws the run wherever it is asked to. prepare_text does the three steps for one string and returns its width.

Parameters

font: *Dynamic_Font

#import "Simp";
#import "File";

draw_label :: (font: *Dynamic_Font) {
    begin_prepare_text(font);
    append_prepare_text(font, "Score: ");
    append_prepare_text(font, "42");
    end_prepare_text(font);

    // The quads are laid out from the origin, one per glyph, left to right.
    last := font.current_quads[font.current_quads.count - 1];
    width := last.lr.x;

    draw_prepared_text(font, 20, 40, .{ 1, 1, 0, 1 });
