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.

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

Explanation
  • enabled
    Enable or disable the mod

    Ping to add to your estimated latency. Useful to avoid considering certain actions that are denied by the server due to a latency spike. Is supposed to represent the current latency fluctuation of your Internet connection. In ms.

  • version
    Version of the configuration. Do not touch!

  • safeMode
    Reduces the likelihood of being flagged by an impossible anticheat. Disabled, the probability is already low. Warning : This can lead to bizarre behavior.

  • crystal

    • enabled
      Enable or disable the crystal prediction
  • minecart

    • enabled

Disclaimer

Versions for 1.21.x are deprecated. I strongly recommend not using them.

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 1.20-1.21.11?

Yes, it is planned.

Compatibility

Eslium should work on any client.
