Implementations

impl BookRenderer

pub fn new(book: Book) -> BookRenderer

pub fn book(&self) -> &Book

The book it draws (its long texts flowed onto more pages).

pub fn set_translator(&mut self, tr: fn(&str) -> Option<String>)

The game’s translations: items’ names in recipe titles, and, for Book::i18n books, the book’s texts — translation keys, looked up with tr (unknown keys stay as they are) and re-looked up whenever the language changes.

pub fn handle_event(&mut self, ev: &str)

pub fn add_recipe(&mut self, id: impl Into<String>, recipe: &Value)

Register a recipe (Yog’s recipe, as Yog Data) so recipe pages can render it visually. Unknown recipe types are ignored.

pub fn render(&mut self, ctx: &GfxContext, sw: f32, sh: f32)

Draws the book into a sw×sh screen — all of it through draw2d (its sprite sheets as the image sources BOOK_SHEET and CRAFTING_SHEET). Draws the book; mods’ pictures (BookPage::Drawn) are left empty — see BookRenderer::render_with.

pub fn render_with( &mut self, ctx: &GfxContext, sw: f32, sh: f32, draw: &mut dyn FnMut(&GfxContext, &str, &Value, [f32; 4]), )

Draws the book, mods’ pictures with draw(ctx, drawer, data, [x, y, w, h]) (screen pixels) — the game calls the mod that registered drawer.

pub fn animated(&self) -> bool

The page shown moves by itself (an entity, a structure, an ingredient’s alternatives): the host should keep redrawing it.

pub fn click(&mut self, x: f32, y: f32) -> Option<String>

A click at (x, y) (screen GUI pixels, as last rendered): what it hit does its thing. The action it was ("next_page", "entry:3", …), if any.

pub fn show(&mut self, entry: &str, page: usize) -> bool

Shows entry (an entry id) at page — its page as written, not counting the pages long text flowed onto — as a reader would have got there; false if there’s no such entry.

pub fn shown(&self) -> Option<(String, usize)>

The entry shown (its id) and the page of it as written, or None on the landing and list pages.

pub fn set_book(&mut self, book: Book)

Replaces the book (an edit), keeping the reader where they were.
