          Dash and Double Jump Minecraft Data Pack
               Datapack
         ‎ ‎ ‎ 1.21.4+

Dash and Double Jump is a Datapack for 1.21.4+ thats allows to dash when double pressing forward key and double jump when double pressing jump key.

There is 4 different dashes :
  • Dash (when you are not underwater, when you are not in Elytra or when you are not riding a Happy Ghast)
  • Swimming Dash (when you are underwater (even if you are in Elytra underwater)) (you dash further but slower than normal dash)]
  • Elytra Dash (when you are flying with Elytra) (you dash further and faster than normal dash)
  • Happy Ghast Dash (when you are riding an Happy Ghast, even if you are underwater) (you dash slower than Elytra Dash)

You can modifiy Configs of the Datapack with the /function dadj:configs command (if you have the permision to use this command).

You can modifiy Player Configs of the Datapack with the /trigger dadj.player_configs command to enable/disable each dash and double jump for your slelf.

In Configs you can :
  • Enable/Disable the Dash/Swimming Dash/Elytra Dash or Double Jump functionnalities, change the delays of double pressing forward/jump key of Dash/Swimming Dash/Elytra Dash and Double Jump, change the cooldown values of Dash/Swimming Dash/Elytra Dash and Double Jump
  • Enable/Disable the cooldown displays of Dash/Swimming Dash/Elytra Dash and Double Jump, enable/disable if Dash/Elytra Dash (not Swimming Dash) is slowed by cobwebs
  • Enable/Disable damages when using Dash/Swimming Dash/Elytra Dash (not Happy Ghast Dash) on mobs and players
  • choose if Dash/Swimming Dash/Elytra Dash/Happy Ghast Dash and Jump Boost can be used by all players or only some players (that have the "dadj.dash" tag for the Dash, "dadj.swimming_dash" tag for Swimming Dash, "dadj.elytra_dash" tag for Elytra Dash and "dadj.happy_ghast_dash" tag for Happy Ghast Dash).
  • choose if Dash/Swimming Dash/Elytra Dash dealing damages ability can be used by all players or only some players (that have the "dadj.dash_damages" tag for the Dash, "dadj.swimming_dash_damages" tag for Swimming Dash, "dadj.elytra_dash_damages" tag for Elytra Dash).

Update #11 : by Loupieur 05/18/2026 3:40:10 amMay 18 @ 7:40 am UTC

Updated Datapack :
  • Now works in 26.2.x

Dashes and Double Jump changes :
  • For 1.21.11+, after a dash, you gain momentum. It gives you also more flight duration (a little bit) in Elytra with the Elytra Dash
  • For 1.21.11+ when you double jump, you go up faster because you gain vertical momentum (no longer with a low gravity attribute), it works even you are falling faster

How do you tweak the strength value to dash further or jump higher?

You have to modify some Datapack files

for the Dashes you have to change the values of the teleportation, or to change how many times the teleportation is repeated

for the Double Jump, you have to change the gravity removed value

history
You have to ask the admin, if it's him who disabled the Double Jump, as a non-admin you can't re enable it (exept if it's not disabled in Configs but it's you who disabled it with Player Configs)

if you are admin, execute /function dadj:configs and select Double Jump settings, and enable it, if it's already enabled, set allow to using Double Jump to All Players, and click on Save, and confirm (if you uses the last version of the Datapack)

i realize now my messages may be to vague if you don't know what's going on i apologize

i am a admin the command that runs for Double Jump when you hit save keeps saying the command doesn't work and i don't know enough about data pack commands to fix the command it runs or know way it wont work. to me the untrained eye it looks just like the other commands that the menu runs idk

If it doesn't works, you are not OP, or you disabled cheats in your world, because you should execute the command with you have the perms.

You can maybe show me a screenshot
