Fixed

• Crashes when using Metal or DirectX. #126

Added

• Task::succeed, which replaces the old Task::new. #66
• Default implementation for ui::widget::slider::State.
• Default, Clone, Copy, PartialEq, and Eq implementations for ui::widget::button::State.
• Additional color constants: Color::RED, Color::GREEN, and Color::BLUE. #77
• Color::from_rgb_u32, which allows to constructs a Color using an hexadecimal literal (0xRRGGBB). #77
• From<nalgebra::Matrix3> and Into<nalgebra::Matrix3> implementations for Transformation. #78
• Game::is_finished, which allows to gracefully quit the game on demand. #79
• Canvas::read_pixels, a method to read the contents of a Canvas as a DynamicImage from the image crate.
• ui::Panel, a dark box that can be used to wrap a widget.
• ui::ProgressBar, a progress bar to give visual feedback to your users when performing a slow task.
• ui::Image, a simple widget to display a graphics::Image in your user interface.
• Mesh::new_with_tolerance, which allows to control the tolerance of line segment approximations. #100
• Game::cursor_icon, which allows customization of the mouse cursor icon.

Changed

• Mesh::stroke now takes an f32 as line_width instead of a u16.
• Task::new now supports a lazy operation that can fail. #66
• Face culling has been disabled for Vulkan, Metal, D3D11, and D3D12 backends. In OpenGL, face culling was already disabled.
• Transformation::nonuniform_scale now takes a Vector. #78
• The logic of KeyboardAndMouse has been split into the new Keyboard and Mouse input trackers. The new mouse and keyboard methods can be used to obtain them, respectively. #69
• The Mouse type can now track additional input:
  • any button click #67
  • wheel movements #67
  • the cursor leaving/entering the game window #67
• The mesh example now has a slider to control the tolerance. #100

Fixed

• Hang when Game::TICKS_PER_SECOND is set as 0. #99

Fixed

• Incorrect buffer sizes in the Mesh pipeline. This caused vertices to entirely disappear when rendering big meshes, leading to a potential crash. 79651405673ecd16da21b887a622f6650b29f38f
• Validation error when rendering meshes using Vulkan, Metal, D3D11, or D3D12. #81

Added

• Documentation about the default coordinate system of a Target.

Changed

• The built-in Debug view now uses µ instead of u for microseconds.

Fixed

• Resizing in Wayland. #58
• Outdated documentation comment in graphics module.
• Documentation typos.

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
• 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.
• 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

Added

• Game::on_close_request to control whether the game should be closed when the window receives a close request by the OS. #14
• input::Event::TextInput event, which triggers on text entry. Contains the character typed as a char. #15
• input::Event::CursorEntered and input::Event::CursorLeft events, which trigger when the mouse cursor enters or leaves the game window, respectively. #15
• input::Event::MouseWheel, which triggers when the mouse wheel is scrolled. Contains the number of horizontal and vertical lines scrolled as f32. #15
• input::Event::WindowFocused and input::Event::WindowUnfocused, which trigger when the game window gains or loses focus, respectively. #15
• input::Event::WindowMoved, which triggers when the game window is moved. Contains the new X and Y coordinates of the window as f32. #15
• Text rendering for the wgpu graphics backend. Vulkan, Metal, D3D11 and D3D12 now support text rendering. OpenGL already supported text rendering. #18
• A changelog. #20
• Example to showcase input handling. #15
• Example to showcase proper colors and gamma correction. #19

Changed

• The debug view is now shown by default when the debug feature is enabled.

Fixed

• Gamma correction in the wgpu graphics backend. Clear colors, font colors, and blending should work as expected in Vulkan, Metal, D3D11 and D3D12. OpenGL was already working properly. #19

Changed

• The wording in the README has been improved.

Fixed

• Compilation failing when debug_assertions and the debug feature were disabled.

Added

• First release! 🎉
