Eslium is a project to predict more things client-side. For example, if you want to use a Crystal, you must wait for the server validation for it to appear. This mod fixes that and therefore compensates for the ping. ## Credits - **Original mod:** [Eslium on Modrinth](https://modrinth.com/project/zaVwh7an) by [@Solmeye](https://github.com/Solmeye) - **Backport:** [@1szco1](https://github.com/1szco1) ## Predictions implemented

Minecarts

When using any type of minecart on a rail, the spawn of the minecart is predicted

End Crystal

When using an end crystal on obisidian or bedrock, the spawn of the end crystal is predicted

## Predictions Added so far: - Consumables - Cooldowns - Crystals - Elytras - Firework - Minecart - Pose - Swap - Weapons - Windcharge - Throwables - Placeables - Interactables - Tools - Combat - Redstone - Anchors - Placement ## Configuration The mod can be configured **in-game** through [Mod Menu](https://modrinth.com/mod/modmenu) (optional dependency) or with the rebindable keybind **`key.clienthings.open_config`** (unbound by default - set it in *Options → Controls*). The configuration is stored at `config/eslium.json`. Every prediction section shares the same base options: - `enabled` - toggle this prediction - `servers` - which server types it applies to (applies if **any** is enabled): - `CUSTOM` - servers using the Eslium protocol - `MODDED` - modded servers - `PLUGIN` - plugin-based servers - `VANILLA` - vanilla servers - `maxTime` - maximum time in ms to keep a predicted (not yet confirmed) action alive - `maxDistance` - maximum distance in blocks for the prediction (where applicable)

Explanation

**Global options** - `enabled` - enable or disable the whole mod - `optout` - opts this client out of the Eslium protocol - `debug` - print debug information to the log (only active while `enabled` is true) - `experimental` - allow experimental predictions - `latencyMargin` - ping in ms added to your estimated latency. Useful to avoid considering actions the server denies after a latency spike. Should represent the current latency fluctuation of your connection. - `version` - configuration version. Do not touch! - `safeMode` - reduces the likelihood of being flagged by an impossible anticheat. The probability is already low when disabled. Warning: this can lead to bizarre behavior. - `simulatedDesync` - percentage (0-100) of the maximum client-server tick desynchronization time used to simulate vanilla desynchronization, which keeps the prediction statistically fair. In singleplayer this is effectively `0`, and against a local server it averages around `50`. Default `100`. **Sections** All sections below share `enabled`, `servers`, and (where shown) `maxTime` / `maxDistance`: `consumables`, `cooldowns`, `crystals`, `elytras`, `firework`, `minecart`, `pose`, `swap`, `weapons`, `windcharge`, `throwables`, `placeables`, `interactables`, `tools`, `combat`, `redstone`, `anchors`, `placement`. - `crystals` - `delay` - fixed delay in ms before a hit crystal is hidden when `dynamicDelay` is off (0-200) - `dynamicDelay` - when enabled, the delay is estimated automatically from your latency instead of using `delay` - `resync` - number of ticks to hide/resync a real crystal before it is shown again (0-50) - `autoDestroy` - automatically remove the client-side crystal prediction after a delay - `enabled` / `maxTime` - `anchors` - `glowstoneSound` - play the charge sound client-side - `clientExplosion` - show the detonation explosion client-side - `reInteract` - allow re-interacting with the anchor before the server confirms - `ghostAnchor` - hide a stale (ghost) anchor block - `placement` - fixes block-placement "ghosting" (a placed block briefly reverting to its old state) - `dynamic` - derive the settle window automatically from your measured latency - `fixedWindowMs` - window used when `dynamic` is false - `floorMs` / `capMs` - lower/upper bounds for the dynamic window

## Disclaimer Allowed on servers such as: - `PvPClub` - `FadedMC` - `Turtled` - `CatPvP` Versions 4.0+ are designed not to trigger anticheats. However, a bug is not inevitable, so it is still recommended to request authorization for this mod before using it on a server. ## FAQ ### How it works ? This mod uses mixins to inject code into Minecraft code. During certain actions, if implemented, the behavior of a vanilla server is replicated on the client side. ### Is this mod a cheat? You might think this mod is a cheat because it gives an advantage to those who don't have it, and these kinds of mods often raise these kinds of questions. Here are a few points : - Some people naturally have lower ping, yet it is not considered cheating - It is possible to have 0ms ping behavior in vanilla, but it is also possible to have it (as far as it is implemented) with any ping and Eslium. - Some mods remain accepted by the community but their behavior is impossible to reproduce in vanilla. I'm thinking in particular of Health Indicator, Armor HUD, AppleSkin, FreeCam, and Ok Zoomer. - This mod has been accepted by Modrinth and some PvP servers. - Sodium optimize FPS, Lithium optimize MSPT, Eslium optimize the ping's impact. - Other ping's optimizer are allowed, such as Marlow's Crystal Optimizer, Hero's Elytra Optimizer, Consumable Optimizer or Anchor Optimizer ### Will versions 4.0+ be backported for minecraft 1.16.5? Yes, it already have. ## Compatibility Eslium should work on any client.
