About this Mod

Original Mod Credit:

WallJump (BF) is a fork of https://modrinth.com/mod/wall-jump-txf by jahirtrap, tailored for the Bannerfall Plugin server experience.

What's different from the original:

  • all jumping requires the Unluck potion effect to be active. Making it unavailable unless players have access to that potion effect.
  • The maximum number of wall jumps per player is read from the bannerfall_rogue_walljumps scoreboard objective, this lets the server control each player's allowance in real time.
  • Updated to Minecraft 1.21.11

Everything else: wall sliding, double jump, speed boost, step assist and configuration, works the same as the original.

Licensed under GPL-3.0, as the original. Full credit to jahirtrap for the base mod.

Features from original mod:

Wall Jump: Hold shift when touching a wall to grab onto it, release when moving a direction to launch yourself in that direction.

Double Jump: Press jump while in midair to perform an additional jump
