Coffee v0.3.0 Release Notes

Release Date: 2019-06-15 // almost 5 years ago

  • ➕ Added

    • 📱 Responsive GUI support! The new ui module can be used to extend a Game and build a user interface. #35
      • GUI runtime based on Elm and The Elm Architecture.
      • Layouting based on Flexbox and powered by stretch.
      • Built-in GUI widgets. Specifically: buttons, sliders, checkboxes, radio buttons, rows, and columns.
      • Built-in GUI renderer. It is capable of rendering all the built-in GUI widgets.
      • Customization. The ui::core module can be used to implement custom widgets and renderers.
    • 👍 Gamepad support. The input::Event enum now has a Gamepad variant. #29
    • 👍 Mesh support. The types Shape and Mesh have been introduced. Rectangles, circles, ellipses, and polylines can now be drawn with ease using fill or stroke modes. #50
    • The Game::LoadingScreen associated type. Given that all the Game associated types implement a trait with a load method, wiring a loading screen now is as simple as writing its name. Because of this, the Game::new method is no longer necessary and it is dropped. #35
    • Input trait. It allows to implement reusable input handlers. #35
    • KeyboardAndMouse input handler. Useful to quickstart development and have easy access to the keyboard and the mouse from the get-go. #35
    • CursorTaken and CursorReturned mouse input events. They are fired when the cursor is used/freed by the user interface. #35
    • 👍 Off-screen text rendering support. Font::draw now supports any Target instead of a window Frame. #25
    • 🐎 Game::debug performance tracking. Time spent on this method is now shown in the built-in debug view. #26
    • 0️⃣ Implementation of Default trait for Text. #25
    • Transformation::rotate. Creates a transformation representing a rotation. #28
    • Batch::clear. Clears the batch contents, useful to reuse batches in different frames.
    • Implementation of Extend for Batch. #37
    • 🐎 Implementation of ParallelExtend for Batch. A Batch can now be populated using multiple threads, useful to improve performance when dealing with many thousands of quads. #37
    • Text alignment. It can be defined using the new HorizontalAlignment and VerticalAlignment types in the graphics module. #35
    • Font::measure. It allows to measure the dimensions of any Text. #35
    • Rectangle::contains. It returns whether or not a Rectangle contains a given Point. #35
    • Sprite::scale. It can be used to change the Sprite size when drawed.
    • 0️⃣ Default implementation for Sprite. #35
    • 💻 Debug::ui_duration. It returns the average time spent running the UI runtime.
    • 💻 A counter example as an introduction to the new UI architecture. #35
    • A user interface example that introduces the different built-in widgets. #35
    • A gamepad example that displays the last gamepad event. #29
    • A mesh example that showcases the different ways to use the new Mesh and Shape types. #50
    • Multiple gravity centers based on mouse clicks in the particles example. #30

    🔄 Changed

    • 🚚 The Game::Input associated type now has to implement the new Input trait. This splits code quite nicely, as the on_input method moves away from Game. It also makes Input implementors reusable. For instance, a KeyboardAndMouse type has been implemented that can be used out of the box! #35
    • Game::draw now takes a Frame directly instead of a Window. #35
    • LoadingScreen::on_progress has been renamed to LoadingScreen::draw and it now receives a Frame instead of a Window. #35
    • input::Event is now split into four different variants representing input sources: Keyboard, Mouse, Gamepad, and Window. Each one of these sources has its own module inside input with an Event type where the old variants can be found. #29
    • 🚚 input::KeyCode has been moved to input::keyboard::KeyCode. #29
    • 🚚 input::MouseButton has been moved to input::mouse::Button. #29
    • Batch::draw and texture_array::Batch::draw do not take a position argument anymore. Using Target::transform before drawing is preferred. #53
    • Font::load has been renamed to Font::load_from_bytes for consistency. #55
    • 🐎 The performance of the particles example has been improved considerably on all platforms. #37
    • 💻 The input example uses the new ui module now.

    ✂ Removed

    • 🍱 The Game::View associated type. Implementors of the Game trait are also meant to hold the game assets now. This simplifies the API considerably, and it helps model your game state-view relationship with precision, avoiding inconsistencies. #35
    • Game::new. Game::load should be used instead. #35
    • Game::on_input. Input handlers now must be implemented using the new Input trait. #35
