DoubleJump999
A mod that allows players to jump a configurable number of times (default is 10 cause why not) with a configurable cooldown (default is 40 ticks or 2 seconds) to prevent flying
About this Mod
DoubleJump999 is a lightweight client-side mod that gives your Minecraft character the power of double jumping, just like in classic platformers! With a single tap of your jump key after your initial jump, you can jump again mid-air — adding mobility, fun, and fluidity to exploration and combat.
No commands. No config (for now). Just install and fly (well, almost).
🕹️ How Does It Work?
🔄 Press jump twice — the second press triggers a powerful mid-air boost!
🕒 A cooldown of 2 seconds prevents accidental spam.
🧠 Smart detection avoids false triggers and respects in-game physics.
✨ Works in Creative, Survival, and Adventure modes.
🧍 Client-side only — won't affect servers or other players.
