DoubleJump999
by ShadowClan
DoubleJump999 lets the character jump again in mid-air, so a second press of the jump key triggers an extra boost while the player is airborne.
What it does
Once the mod is installed, a single tap of the jump key after the initial jump starts another jump in mid-air. The number of air jumps is configurable and defaults to 10. A cooldown, set to 40 ticks by default (2 seconds), stops repeated presses from producing continuous flight, and smart detection ignores presses that would not count as a deliberate second jump, so in-game physics stays intact.
The mod works in Creative, Survival and Adventure modes and is aimed at mobility, exploration and combat in vanilla-style or lightly modified modpacks. Both the server and every player need it, so it has to be installed on each side. Files are published for Forge only, for six game versions 1.20.1 – 1.20.6, with 1.0.2 for 1.20.6 as the latest file. DoubleJump999 is not open source; it is released under All rights reserved.
Key features
Mid-air double jump
A second press of the jump key in the air triggers a boost, giving the character a classic double jump.
Configurable jump count
The number of extra jumps allowed in one airborne session can be changed, with 10 as the default.
Cooldown between jumps
A cooldown of 40 ticks (2 seconds) by default prevents accidental spam and continuous hovering.
Smart trigger detection
Presses that would be false triggers are filtered out, so the extra jump respects the game's physics.
