StepUpAgain
Increase your step height - like autojump but without the disadvantages... Again!
About this Mod
This is an updated version of the existing Fabric StepUp mod, which in turn is an updated version of the original Forge-based StepUp mod. All I did was update it to use the attribute system in 1.20.6 as the old method no longer exists.
StepUpAgain helps you to climb blocks without needing to jump, or autojump. While it's similar to enabling autojump, it doesn't come with the hunger penalty that jumping has.
It allows you to switch between "normal mode" and "autojump mode" which are what the client normally does, and "big steps mode" which allows you to climb full blocks without jumping. Modes can be switched using the J key at any time; the key can be changed in options as usual.
The mod is client side and should work with vanilla servers as well, except if the server has some code to prevent the mod from working. Because of this, the mod saves its configuration per server, so you can turn it on wherever it works without hampering servers where it doesn't.

StepUpAgain server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.
Is StepUpAgain compatible with fabric?
StepUpAgain officially supports fabric for Minecraft 1.21.1, 1.21, 1.20.6. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with StepUpAgain – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if StepUpAgain consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
