StepUpAgain

An updated build of StepUp for modern and legacy Minecraft versions on Fabric, with current work also covering Forge 26.1.

StepUp increases the player's step height so you can walk up blocks smoothly instead of jumping into them. At first glance it can feel similar to vanilla auto-jump, but the movement is more direct, more precise, and avoids the constant repeated jumping behavior.

This makes the mod especially useful for normal traversal, bases, caves, hills, stairs, uneven terrain, and any situation where vanilla auto-jump feels intrusive or slow.

What the mod does

• Lets you walk up full blocks more smoothly.
• Keeps movement feeling closer to normal walking than to jumping.
• Works entirely on the client, so it can be used in singleplayer and on vanilla-compatible servers.
• Saves its movement mode per server.
• Supports optional in-game configuration through Mod Menu and Cloth Config.

In practice, StepUp changes how movement feels when you approach a block that would normally require a jump. Instead of repeatedly hopping over terrain, the mod raises the player's step height and lets the character walk over the edge in a more continuous way.

Why use it instead of vanilla auto-jump

Vanilla auto-jump can be useful, but many players dislike it because it:

• triggers when you do not want it to,
• changes movement timing,
• makes traversal feel less precise,
• adds repeated jump behavior,
• and applies the normal hunger cost of jumping.

StepUp keeps the useful part, walking over obstacles, without inheriting those downsides.

Modes

The mod supports three movement modes:

StepUp

• Raises the player's step height above vanilla.
• Lets you walk over full blocks without jumping.
• Falls back to normal step height while sneaking for better control.

Disabled

• Turns StepUp off.
• Keeps vanilla auto-jump off.

Vanilla Auto Jump

• Disables StepUp's custom step-height behavior.
• Re-enables Minecraft's normal auto-jump option.

Controls

By default, the mod adds two keybinds:

• J switches the active movement mode.
• K toggles whether Vanilla Auto Jump is included in the J cycle.

When the vanilla mode toggle is disabled, J only switches between:

• StepUp
• Disabled

The keybinds can be changed in Minecraft's Controls menu, and the mod uses its own StepUp keybind category on supported versions.

Configuration

StepUp stores its settings in:

config/stepup.json

The configuration is saved per server. That means:

• singleplayer can have one default behavior,
• one multiplayer server can use StepUp,
• another can stay on Disabled,
• and another can stay on Vanilla Auto Jump.

The config also stores whether the vanilla auto-jump mode should be available in the J toggle cycle.

If Mod Menu and Cloth Config are installed, this setting can be changed in-game. They are optional dependencies, not required ones.

Supported versions

Current builds in this project cover:

Fabric

• 1.14 through 1.14.4
• 1.15 through 1.15.2
• 1.16 through 1.16.5
• 1.17 through 1.17.1
• 1.18 through 1.18.2
• 1.19 through 1.19.4
• 1.20 through 1.20.6
• 1.21 through 1.21.11
• 26.1

Forge

• 26.1

Requirements

Requirements depend on the target file/version, but in general you will need:

• the correct Minecraft version,
• the correct loader for that file,
• Fabric API on Fabric builds,
• and the matching Java version for that target.

Mod Menu and Cloth Config are optional.

Installation

1. Install the correct loader for your Minecraft version.
2. On Fabric, install Fabric API for the same target version.
3. Put the StepUp jar in your mods folder.
4. Start the game.

Because the mod is client-side, it does not require a server-side installation for normal use.

Notes

• This mod is designed to work on the client only.
• It should work with vanilla-compatible servers in normal cases.
• Some servers may still interfere with the effect if they change movement behavior or enforce custom restrictions.
• Very old Minecraft versions may need older loader/mod combinations to match the target release correctly.

This fork exists to keep the mod usable on newer and older supported Fabric versions, while also maintaining current compatibility work for Forge 26.1.

The upstream history of the project also includes earlier StepUp/StepUpNext work reflected in the archived repository and license notices. This fork keeps that lineage intact while updating compatibility for current targets.
