About this Mod

🧪 XP Simplifier

A mod focused on providing full control over XP, customizing XP values for every source independently with seamless support for both vanilla and modded content.

💡 Why Use XP Simplifier?

Perfect for:

  • 🎮 Modpacks that need XP rebalancing
  • ⚔️ Hardcore servers with punishment systems
  • 🌾 Economy/progression servers
  • 🧩 Heavy modpacks with inconsistent XP rewards
  • 🛠 Players who want full control over progression

🎯 Prime Goals

  • Control over XP behaviour (2 modes):
    • Direct xp gaining (no orbs)
    • Vanilla xp gaining (with orbs)
  • Full control over:
    • XP sources
    • XP values
    • Multipliers since v.2.0.5
  • User-friendly config (all split into sources)

🧪 Features

Version 2.0.5+:

  • In-game config via menu/mods (Fabric requires Mod Menu / NeoForge uses built-in config screen).
  • Config changes apply instantly — no restart required.
  • Client is optional, but required for in-game config menu, recommended for OPS.
  • Config Sync (config changes via in-game menu are synced across all server players so modded player = config view).
  • 2FA verification for config changes -> OP permissions (level 2+) + User flag.
  • If null + OP (level 2+) -> access denied.
  • If true + OP (level 2+) -> access granted.
  • If true + non-OP -> access denied.
  • If false + OP (level 2+) -> access denied.
  • If false + non-OP -> access denied.
  • Commands access for OP players (level 2+) can be revoked via LuckyPerms.
  • Per world instance config (config changes via in-game menu affect only current world instance).
  • Translation support.

🛠 Commands

Command Description
/xps add <player> <true/false> Adds player to config change list (true = allow, false = deny)
/xps edit <player> <true/false> Edits player in config change list (true = allow, false = deny)
/xps delete <player> Deletes player from config change list
/xps list Lists all players in config change list
/xps mapview <true/false> Toggles map view for config categories (true = show, false = hide); affects all players globally unless per-player editing is enabled.


🧩 Configuration Categories

All sources are split into categories, each with its own config file:

  • Blocks.json
  • Entities.json
  • Crops.json
  • Smelting.json
  • Trading.json
  • Breeding.json
  • Fishing.json
  • Grindstone.json

(no achievements)

Each category contains subcategories.
Subcategories exist purely to keep the config clean and tidy.


Multipliers since v.2.0.5

  • Each source has a multiplier field that multiplies the final XP value by the specified amount.
  • Multipliers are applied after all other calculations, so they can be used to adjust the final XP values without changing the base values for each source.
  • Multipliers affects both per-source modes -> ON and VANILLA.
  • Multipliers are set as a float value, so you can use values like 0.5 for half XP or 2.0 for double XP.

🎲 XP Calculation Types

Two XP calculation methods are supported:
supports negative values in "simple" OrbMode

  • Random
    • Grants a random amount of XP between min and max
  • Fixed
    • Grants a fixed amount of XP
    • 0 means no XP is granted

🔧 Mending Rework (Anvil-Based)

Mending has been reworked to function without them while remaining balanced mainly due to OrbMode -> "simple".

🔨 How Mending Works

  • Items with Mending can be repaired in an Anvil
  • No additional items are required
  • Repair cost is XP only

Default formula:

Since ver.2.0.5, the XP cost formula takes XP Points instead of XP Levels, so the cost is more granular and allows for more precise balancing.
_can be changed via Config file or via In-Game Menu since v.2.0.5.

  • DEFAULT:
1 durability point = 2 XP_Points (min. 1lvl always)
  • Example:
- Diamond Sword durability: 1561
1561 * 2 = 3122 XP_Points

Level amount required depends on player level


📉 Max Cap Behavior

maxAnvilRepairCost limits the maximum XP levels required for a full repair.
For higher caps like >30, to avoid To expensive! message, ANTE mod is recommended.

Lower values cap the total XP cost for full repairs.


⚠️ Important

  • Setting "xpRepairEnabled": false
    • Disables Mending completely if orbs are canceled

🧩 Compatibility

  • Minecraft 1.20-1.21.1
  • Fabric / NeoForge (v. 2.0.5)
  • Server-side friendly
  • Client is optional (only for in-game config menu -> v.2.0.5)
  • Compatible with modded blocks/entities/etc

TL;DR

VERSIONS 1.0.+ :

  • Once updated to newer version -> create a backup of your existing configs and delete whole folder. Let the mod initialize the defaults and then replace all new maps with yours but be careful, few changes were made to versions 1.+ :)

VERSIONS 2.0.+ :

  • No map JSON file structure changes, but new fields were added to the main config. Once initialized -> all defaults load to memory, if any change made, config appears.

FAQ

Q: Do I need to restart for config changes?

  • A: Since ver.2.0.5, no restart is needed for config changes to take effect.
  • For older versions -> configuration files are editable only manually and require a restart to take effect.

Q: Can I use decimal XP for mining?

  • A: No, only smelting supports decimal values. Blocks/Entities/Fishing/Breeding/Trading must be integers.

Q: How do I prevent XP duplication?

  • A: Since the mod supports only 2 modes -> "simple" and "vanilla", there's no XP duplication.

Q: What about negative values while breaking blocks/killing entities?

  • A: If "OrbMode" -> "simple", all actions (except smelting and merchants) accept negative values so players can be punished for killing entities like villagers or so.
    Keep in mind that while setting up negative values -> "min" must be lower than "max".

Q: Do experience bottles work without entity XP enabled?

  • A: No, experience bottles are treated as entities, so they require entityXpMode: "vanilla" || "on".

Q: What about modded content?

  • A: All default/vanilla fallbacks exist, so once all options set to -> on || vanilla, all sources should work fine.
