From Zero to CurseForge: How to Build Your First Hytale Mod

You don't need to be a programmer to make a Hytale mod. The game ships with visual scripting tools, JSON-based configuration, and Blockbench (the official 3D modeling tool) that together let you create custom items, creatures, recipes, and gameplay mechanics without writing a single line of code. This guide walks you through the process of building a simple mod and getting it published on CurseForge. If you've been curious about modding but didn't know where to start, this is your entry point. The Three Modding Paths Hytale offers multiple approaches to mod creation, each suited to different skill levels and goals: 1. JSON Data Packs (Easiest) Modify existing game behavior by editing configuration files. No tools required beyond a text editor. You can change crafting recipes, adjust NPC stats, modify drop tables, and tweak world generation parameters. Best for: Balance tweaks, custom recipes, modified drop rates, world generation adjustments. 2. Visual Scripting (Intermediate, Coming Soon) A node-based scripting system inspired by Unreal Engine's Blueprints is planned for Hytale. Hypixel Studios announced it would arrive "shortly after launch," and it will let you connect nodes with visual wires to create gameplay logic without memorizing programming syntax. The World Gen V2 node editor already uses a similar visual approach for world generation. Best for: Custom game mechanics, interactive objects, triggered events, gameplay modifications (once released). 3. Java Plugins (Advanced) Full programming access for complex server-side logic. If you've written Bukkit or Spigot plugins for Minecraft, the concepts are familiar. Best for: Complex systems, economy plugins, custom UIs, deep integration with game internals. This guide focuses on paths 1 and 2, since they require no programming. Setting Up Your Workspace Before you start building: Create a dedicated world. Open Hytale, create a new Creative Mode world. This is your testing environment. Find your mod folder. Hytale mods live in the server's mod directory. For a local game, this is typically in your Hytale installation under the server folder. Create your mod's folder structure. Hytale packs use a manifest.json file and organize content under Common/ and Server/ directories: my-first-mod/ ├── manifest.json (pack metadata) ├── Common/ (shared assets: textures, models, icons) │ └── Items/ (item models and textures) └── Server/ (server-side data) ├── Item/Items/ (item definitions) ├── NPC/Roles/ (NPC behavior configs) └── Drops/ (drop table configs) Write your manifest.json. This file tells Hytale about your pack: { "Group": "com.yourname", "Name": "My First Mod", "Version": "1.0.0", "Description": "A simple mod to learn the basics", "Authors": ["YourName"] } Project 1: Custom Crafting Recipe (JSON) The simplest mod you can make: a new crafting recipe. Let's create a recipe that lets players craft a diamond pickaxe from different materials than the default. Navigate to your mod's recipes/ folder Create a JSON file (e.g., custom_pickaxe.json) Define the recipe using Hytale's recipe format, specifying the input items and output Save, reload your mod, and test at a workbench The exact JSON format follows Hytale's recipe schema, which you can reference from existing game files in the server's data directory. Look at how default recipes are structured and use them as templates. Project 2: Modified NPC Behavior (JSON) Let's make a zombie that's faster and drops better loot: Find the base zombie NPC definition in the game's data files Copy it to your mod's npcs/ folder Modify the speed, health, damage, and drop table values Add your custom zombie as a variant that spawns alongside regular zombies This is how many of the NPC mods on CurseForge work. "Mob Variants" and similar mods are primarily JSON modifications to existing NPC definitions with adjusted stats and new drop tables. Looking Ahead: Visual Scripting When Hytale's visual scripting system launches, it will open up a third modding path for non-programmers. Based on what Hypixel Studios has shared, the system will work similarly to Unreal Engine Blueprints: you'll connect trigger nodes (like "On Player Step") to action nodes (like "Create Explosion") with visual wires, building gameplay logic without writing code. The World Gen V2 node editor, already available for world generation modding, gives a preview of how this approach works in practice. Once the general-purpose visual scripting system ships, it will let modders create interactive objects, custom game mechanics, and triggered events by connecting building blocks visually. In the meantime, JSON data packs and Java plugins cover the full range of modding needs. Using Blockbench Blockbench is the official 3D modeling tool for Hytale, available as a free desktop application. With the Hytale plugin installed, it exports directly to .blockymodel and .blockyanim formats, validates pixel density, and enforces Hytale's geometry constraints. For your first mod, you might not need custom models. But if you want your mod to stand out visually, Blockbench is where you'll create unique item appearances, custom block shapes, and NPC models. Testing Your Mod Testing is straightforward since mods are server-side: Place your mod folder in the server's mod directory Start (or restart) the server Join the server and verify your changes work Check the server console for any error messages related to your mod Hytale's mod system reports errors clearly. If your JSON has a syntax error or your visual script references something that doesn't exist, the console tells you exactly what's wrong and where. Publishing to CurseForge Once your mod works: Create a CurseForge account if you don't have one Apply for Mod Author status on the Hytale section Create a new project with a clear name, description, and at least one screenshot Upload your mod files as a zip archive Write installation instructions so server owners know how to set it up Submit for review Good CurseForge listings include screenshots, clear descriptions, known issues, and a changelog. These aren't just nice-to-haves; they directly affect whether server owners choose your mod over alternatives. What to Build Next Once you've published your first mod, consider: Custom quests: Use visual scripting to create multi-step quest chains New creatures: Combine Blockbench for visuals with NPC framework JSON for behavior Building blocks: Create decorative block sets for builders Mini-games: Script custom game modes using visual scripting Enter the New Worlds contest: $100,000 in prizes for WorldGen, NPC, and Experience mods The Hytale modding community is active on the CurseForge Discord server and the official Hytale Discord. Both are good places to get feedback, find collaborators, and learn from experienced modders. If your mod is designed for multiplayer, consider setting up a test server and listing it on HytaleCharts so players can try your creation.
