About this Mod

Simple spleef functionality added to Cobblemon.
There is currently no infrastructure, but if there is any interest in this mod, I will add it later on. Currently, there is only functionality related to some of the pokéballs when it hits certain blocks.

As of version 1.2, spleef only works with Snow Blocks, and that is the only block that causes the special behavior. The following poké balls have custom behavior:

Platform Hit Effects

  • Pokeball
    • Removes the snow block it hits
  • Great Ball
    • Causes a tiny explosion and gives huge knockback when it hits a snow block
  • Ultra Ball
    • Causes a bigger explosion upon hitting snow blocks

Player Hit Effects

  • Heavy Ball
    • Applies slowness to your opponent!
  • Dive ball
    • Forces your opponent into swimming mode for 1 second
  • Ancient Jet Ball
    • Sends your opponent flying
  • Dusk Ball
    • Gives your opponent darkness
  • Quick Ball
    • Gives your opponent speed, making it harder to parkour around in the arena
  • Wing Ball
    • Makes your opponent levitate, possibly helping them up another layer or fall to their death!

Misc balls

  • Master Ball
    • Spawns Ultra Balls with custom behavior at its location while it is flying through the air
  • Heal Ball
    • Spawns a tiny platform 1 second after being thrown

If you have any questions or would like to suggest new features, feel free to reach out to me on Discord.

Frequently Asked Questions

PolarSpleef server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is PolarSpleef compatible with fabric?

PolarSpleef officially supports fabric for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with PolarSpleef – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if PolarSpleef consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
