120+ crate.
121+
122+ The game uses different ship shapes, unlike the traditional vertical/horizontal

159+
160+ The Hat Chooses the Wizard is a 2D platformer for the Game Boy Advance.
161+
162+ It was made for this year's Game Maker's Toolkit (GMTK) game jam with the theme
163+ joined together and came in the top 25% of over 5800 entries. The game plays
164+ over 12 levels with the core mechanic being to throw your hat and then
165+ accelerate towards it. You can play it on a web based emulator embedded on the
166+ [ itch] [ hatchooseswizard ] page.
167+
168+ The game is written in pure Rust and uses [ agb] [ agblibrary ] to
169+ interface with the hardware. The library is designed to allow you to write games
170+ without needing a detailed understanding of the hardware while still giving full
171+ access to all of its capabilities. It is under active development with
172+ plenty more features on the way.
173+
174+ You can find the source code for the game [ here] [ hatchooseswizardsource ] and all
175+ feedback is welcome.

255+ [ GGRS] ( [crates.io](https://crates.io/crates/ggrs) ) by [ @g_schup] are pure
256+ Rust implementations of the [ GGPO] rollback networking library.
257+
258+ ![ Evo Moment 37] ( rollback.jpg )
259+ _ [ Evo Moment 37] ( https://www.youtube.com/watch?v=JzS96auqau0 ) :
260+ Only offline or with rollback!_
261+
262+ Rollback networking is a peer-to-peer network technique designed to hide
263+ network latency in fast-paced games with precise inputs. Traditional techniques
264+ account for network transmission time by delaying the game execution, resulting
265+ in a sluggish game-feel. Rollback uses input prediction and speculative
266+ execution instead. Upon receiving inputs from remote clients, resimulation of
267+ incorrect game states occurs. This allows for gameplay that "feels just
268+ like offline". The open source standard for rollback netcode [ GGPO] is used
269+ in successful games like Skullgirls, Guilty Gear XX Accent Core +R or
270+ Fightcade. For further explanation about rollback,
271+ [ click here] ( https://ki.infil.net/w02-netcode.html ) .
272+
273+ Two projects in Rust were independently created to provide a working
274+ implementation as well as helpful resources for developers.
275+ backroll-rs features an added abstraction for the transportation layer and
276+ also provides a bevy plugin, [ bevy-backroll] . GGRS replaces the
277+ C-style callback API of GGPO with a simpler, more understandable control flow.
278+ The authors of both libraries recommend backroll-rs for developement,
279+ as it is currently more actively collaborated on.
280+ GGRS is recommended as a learning recource and entry point,
281+ with a plethora of internal documentation and explanation.
282+
283+ The main requirement to make use of both presented libraries is determinism
284+ in your game execution. Resimulation requires that the result of progressing
285+ the game state depending on the given inputs yield the exact same results
286+ every time. Additionally, you need to be able to load, save and progress
287+ your gamestate without rendering the outcome.
288+
289+ If you are interested in integrating rollback networking into your game or
290+ just want to chat with other rollback developers (not limited to Rust),

350+ ### [ wgpu] family re-union
351+
352+ ![ wgpu family reunion] ( wgpu-family-reunion.svg )
353+
354+ [ wgpu] is a [ WebGPU] implementation in Rust. It is safe, efficient,
355+ and portable: it can target both native and the Web.
356+
357+ [ Family reunion] is by far the biggest change in ` wgpu ` project since
358+ the inception. First, the Rust API of [ wgpu-rs] was moved to the main
359+ [ wgpu] repository. Second, the whole base was relicensed under MIT/Apache2.
360+
361+ [ gfx-hal] - the Vulkan Portability-like graphics API abstraction -
362+ was detached from the project. Instead ` wgpu ` got its own in-house unsafe
363+ abstraction called "wgpu-hal" developed within the [ wgpu] repository.
364+
365+ The team released [ wgpu-0.9] right before this transition, to give the new
366+ graphics infrastructure more time to take shape. At the time of writing,
367+ supported backends on the new HAL include Vulkan, Metal, and OpenGL ES3.
368+
369+ Finally, the testing infrastructure received a major upgrade. It started
370+ rendering the examples on the available adapters and compraring the results
371+ with reference images.
372+ This includes automatic testing using software adapters on CI.
