WallJumpBF
A fork of WallJumpTXF with Bannerfall SMP Plugin Support
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
