This mod can only be used in a developer workspace, at least until a library replacement 5 | mechanism is developed for production environments. You also shouldn't trust it with any worlds you particularly 6 | care about until more extensive testing is done. 7 | 8 | No guarantee is made that this project will receive any further development or that it will even be maintained. 9 | 10 | ### Preface 11 | 12 | The release of Minecraft 1.13 brought the concept of "data fixers" to the game, enabling seamless and incremental 13 | upgrades for old world data. The theory behind the implementation is cutting edge stuff, but in the real world, things 14 | are less than ideal. 15 | 16 | During start-up, the game will build (and optimize) data fixers for every supported version schema the game can 17 | upgrade from. This process accounts for a huge portion (>85%) of the time the game spends sitting at the loading screen, 18 | and will often bring most systems to their knees while it does so due to how it maximizes for parallelization. 19 | 20 | Unfortunately, this problem has only continued to escalate with recent releases of the game. Minecraft 1.16 introduces 21 | many new data fixers, and as if insult to injury, seemingly no longer waits for them to be finished loading before the 22 | loading screen vanishes, leading to excessive lag on the main menu while they continue to build. 23 | 24 | This mod attempts to solve, or at least greatly improve, the problem of data fixers being very CPU intensive to compute. 25 | Ultimately the best solution would be to pre-compile the optimized data fixers, so that the client doesn't need 26 | to spend its time constantly re-building them... but alas that is left to Mojang. 27 | 28 | ### For developers 29 | 30 | This repository is just the loader shim to bring the [optimized fork of DataFixerUpper](https://github.com/jellysquid3/DataFixerUpper/) 31 | into the game client. As such, none of the actual optimizations are implemented here. If you'd like to start hacking, 32 | checkout the `modules/DataFixerUpper` library and make a new branch there. 33 | 34 | #### Cloning the repository 35 | 36 | This project makes use of [Git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules). When cloning the 37 | repository, you must be sure to clone the submodules. 38 | 39 | If you're cloning the repository for the first time, use the following: 40 | 41 | ``` 42 | git clone --recurse-submodules https://github.com/jellysquid3/cadmium-fabric.git 43 | ``` 44 | 45 | Otherwise, to clone the submodules in an already cloned repository: 46 | 47 | ``` 48 | git submodule update --init --recursive 49 | ``` 50 | 51 | ### License 52 | 53 | Cadmium is made available under the MIT license, a free and open-source license.
