C++ (Cpp) retro Examples

Example #1

void SelectLevelScreen::draw_level_name() const {
    const String chapter_name((*_level)->name);

    const InterfaceItem& i = item(NAME);

    RgbColor   color = GetRGBTranslateColorShade(AQUA, VERY_LIGHT);
    StyledText retro(sys.fonts.title);
    retro.set_fore_color(color);
    retro.set_retro_text(chapter_name);
    retro.wrap_to(440, 0, 2);

    Rect  bounds = i.bounds();
    Point off    = offset();
    bounds.offset(off.h, off.v);
    retro.draw(bounds);
}
