Hytale Better Stacking Mod

With this mod, you can adjust the inventory flow to automatically route picked-up items or entire item stacks to existing stacks in the offhand or backpack.

Base Features

Item Routing: Automatically move items to your offhand (utility bar) or backpack based on your personal configuration

Two Stacking Modes:

Partial (Default): Only adds new pickups to the existing stack in your offhand/backpack
Full: On pickup, moves the entire stack from your main inventory to the existing stack in your offhand/backpack

Per-Slot Configurations: Configure your offhand and backpack independently. You can have the offhand on "Partial" and the backpack on "Full" simultaneously. Can be configured via commands (See "Commands" section)

Persistent Settings: Your configurations are saved to your player profile and will persist across server restarts or re-joins

Commands

Use the /stacking command to manage your settings:

/stacking status: Show the current status of your stacking configuration

/stacking <slot>: Toggles stacking for the specified slot (offhand or backpack) using the Partial mode

/stacking <slot> --full: Toggles stacking for the specified slot using the Full mode

Global Default Cofiguration

If you want to adjust the default settings for all players on your server, you can adjust the BetterStacking.json config file. On the first server start it will be auto generated in the folder [YourServer]/mods/org.senix_BetterStacking. The default configuration where both slots are enables and in partial mode looks like this:

{
"DefaultPolicies": {
  "OFFHAND": {
    "Enabled": true,
    "PartialOnly": true
  },
  "BACKPACK": {
    "Enabled": true,
    "PartialOnly": true
  }
}
}

How to Use

The mod can be downloaded from Curseforge or Nexusmods. Just add the .jar to your server's mods folder (or directly install on your server using the Curseforge UI).

After installing the mod, the first time you join the server, the settings for both slots (offhand and backpack) are initialized with the feature enabled in partial mode. You can always use the commands above to adjust the configuration.

Possible Future Adjustments

Add settings menu UI to adjust per-slot configurations without commands
Add priority system to choose whether the offhand or backpack should be checked first when both are enabled
