Changelog History

• v0.2.8 Changes

  February 01, 2019

  ➕ Added

  • The time::get_fps function was added, which returns the current FPS, averaged out over the last few seconds. (@selimeren in #96)

• v0.2.7 Changes

  January 23, 2019

  🔄 Changed

  • 🐎 We now use the hashbrown implementation of HashMap/HashSet instead of the fnv hasher. The hope was that this would give a performance boost, but it didn't seem to have any real observable impact :( That said, several of Tetra's dependencies use hashbrown, so in the interests of keeping the dependency tree light, we're switching anyway.

  🛠 Fixed

  • 🛠 A race condition between Rodio and SDL has been fixed.
  • ✅ While testing hashbrown integration, it was found that the benchmark numbers in the FAQ were slightly inaccurate - this has now been fixed.

• v0.2.6 Changes

  January 20, 2019

  ➕ Added

  • Audio playback has been added, using Rodio as the backend!
  • 🐎 A port of the popular 'BunnyMark' benchmark has been added, which can be helpful for comparing relative performance of different versions/configurations of Tetra.
  • The documentation has been updated to detail the sdl2_bundled and sdl2_static_link features.

  🔄 Changed

  • 🚀 The code that handles sprite transformations has been rewritten, and is now around 10 times faster than 0.2.5 in debug mode, and twice as fast as 0.2.5 in release mode.

  🗄 Deprecated

  • 🏗 The build_matrix method on DrawParams was meant to be an internal utility, not a part of the public API. Tetra no longer uses it, so it has been deprecated, and will be removed in 0.3.

• v0.2.5 Changes

  January 06, 2019

  ➕ Added

  • Custom shaders can now be used for rendering!

  🛠 Fixed

  • The parameters contained within an instance of DrawParams are now publicly accessible - without these, it wasn't possible to write a proper custom implementation of Drawable.
  • Shaders now bind their outputs explicitly - this should help with compatability.

• v0.2.4 Changes

  January 04, 2019

  🛠 Fixed

  • 🛠 Fixed an issue where the OpenGL context would fail to initialize when using NVidia's proprietary Linux drivers.

• v0.2.3 Changes

  January 03, 2019

  ➕ Added

  • 👍 Tetra now has support for gamepads! The API is roughly the same as that of keyboard and mouse, aside from having to specify which gamepad's state you're querying.

  🔄 Changed

  • Text is now drawn using the same shader as everything else - this likely won't be noticable now, but it will make things a lot easier once custom shaders get added!

  🛠 Fixed

  • 🛠 Some subtle issues around font cache invalidation have been fixed - in general we now let glyph-brush handle that side of things.
  • 🛠 Texture flipping was broken in 2.0 - this has now been fixed.
  • The OpenGL context now explicitly requests a 32 bit color buffer and double buffering.
  • Shaders now bind their texture sampler explicitly, which should avoid black screens on some drivers.

• v0.2.2 Changes

  December 24, 2018

  ➕ Added

  • Tetra now has a website, with a tutorial on how to get started using it.
  • run_with is now less restrictive about what kinds of closure it will accept.

  🔄 Changed

  • 🍎 We now always request an OpenGL 3.2 core profile context - this is required for us to support MacOS.

  ✂ Removed

  • The TETRA_OPENGL_FORCE_CORE_PROFILE environment variable has been removed, since we now always force a core profile.

• v0.2.1 Changes

  December 22, 2018

  ➕ Added

  • Shader errors are now properly reported via TetraError::OpenGl.

  🔄 Changed

  • 🛠 The shader attribute order is now explicitly defined - this fixes an issue with black screens on some drivers.

• v0.2.0 Changes

  December 21, 2018

  ➕ Added

  • Texture now has methods to get the width and height.
  • The bundled and static-link features from the sdl2 crate can now be used through Tetra by enabling the sdl2_bundled and sdl2_static_link features. (@VictorKoenders in #33)
  • 🆕 New methods have been added to allow iterating over down/pressed/released keys on the keyboard. (@VictorKoenders in #35)
  • Text input typed by the user can now be retrieved using the input::get_text_input function. (@VictorKoenders in #36)
  • Text now has a method for efficiently calculating (and caching) the outer bounds of the text. (@VictorKoenders in #41)
  • 🆕 New methods have been added to Animation, allowing it to be modified after it is initially created. (@VictorKoenders in #48)
  • There are now numerous different ScreenScaling types that can be chosen from.
  • Extra options have been added to the ContextBuilder, allowing you to start the window in various different states (e.g. fullscreen).
  • There are now many new methods for manipulating the window/game loop in the window module.
  • ⚡️ The update and draw methods on State are now both optional.
  • The graphics module now re-exports Vec2.
  • 👀 In addition to the normal run method, there is now also a run_with method that uses a closure to construct the State. This is handy when method chaining - see the examples for how it can be used.
  • 👯 Public types now implement Debug and Clone where appropriate.
  • TetraError now implements the standard library Error trait.

  🔄 Changed

  • ⬆️ The library has been upgraded to the 2018 edition of Rust.
  • 0️⃣ ContextBuilder::new now takes the title and size as parameters. The old behavior of the function can be replicated by using ContextBuilder::default instead.
  • 🆓 run is now a method on Context, instead of a free function.
  • ⚡️ The update and draw methods on State now return tetra::Result, allowing errors to be returned (or propagated via the ? operator). Any errors returned from these methods will stop the game - your main method can then handle the error (e.g. log it out).
  • 👍 The scale option on ContextBuilder has been renamed to window_scale, to better reflect its behavior.
  • Shader::from_file is now called Shader::new, and Shader::new is now called Shader::from_string. This is more consistent with the other constructors.
  • Tick rates are now specified in ticks per second.
  • The ContextBuilder no longer consumes itself when called - this is more flexible for e.g. calling methods inside a conditional.
  • 🚚 quit has been moved to the window module.
  • set_tick_rate has been moved to the time module.
  • The functions for getting the game's internal width/height have been renamed to disambiguate them from the functions for getting the window width/height.
  • Matching on TetraError will now force you to add a wildcard arm. This will prevent the addition of new error types from being a breaking change.
  • Shader::from_string now returns Result, as proper error handling will be added to to it eventually.

  🛠 Fixed

  • The model matrix is now calculated once per Drawable, instead of once per vertex. This should speed up rendering.
  • The top left corner of a NineSlice no longer gets distorted if the x and y of the fill_rect aren't equal.
  • The renderer now automatically flushes instead of panicking if it hits capacity.
  • The renderer will now batch up to 2048 sprites, instead of 1024.
  • 0️⃣ The default shaders have been rewritten in an older/more compatible syntax, in order to fix some issues with black screens on Mesa drivers.
  • The is_mouse_button_pressed and is_mouse_button_released functions now work correctly.

• v0.1.6 Changes

  December 09, 2018

  ➕ Added

  • The Font and Text types have been added, allowing you to render out text using a TTF font.
  • Inspired by FNA, the TETRA_OPENGL_FORCE_CORE_PROFILE environment variable can now be set to force the application to run using the 3.2 core profile. This might end up getting removed in favour of a more robust solution later on, but it's handy for testing (e.g. Renderdoc requires the core profile to be enabled).

  🛠 Fixed

  • The internal framebuffer is now an RGB texture instead of an RGBA texture - this was causing some strange issues with blending.
