1.0.0 coming soon

The mod engine
for Minecraft.

Make Minecraft mods without writing code. Models, textures, animations, screens, quests and the rules that tie them together, in one desktop studio. Press Play and the mod opens in the game.

Watch on GitHub See what it makes

Modryos' first screen: What are you making today?

The New window: What are you making? Kinds listed in seven groups, here crafting and loot

Every mod starts here: press New and pick what to make, from a block or a tool to a machine, a creature or a screen.

1 · Models and animation

Shape it, paint it, make it move.

A model editor with a live 3D preview, a pixel painter for textures, and a timeline for animations. The wyrm here was modelled, its scales painted and its breathing animated this way, all in the same project as the rest of the mod.

Painting the dragon scale's texture — Texture

Animation, playing

2 · Screens

Build a screen here. Open it there.

Machine screens, HUD bars, books and quest views. Drag controls onto the screen, give them a look, and tie them to what the mod knows: the foods a player has tasted, a tank's level, their mana. What you lay out is what opens in the game.

3 · Rules and code

Say what happens. In sentences, or in Java.

When the sword hits something, set it on fire, and if it was a player, warn whoever holds the sword. Conditions nest into groups the way a game engine's visual scripting does. Each sentence is Java underneath, the code view is one click away, and your own Java classes and mixins sit right beside it.

Conditions grouped with If, Else if and Else — Conditions

4 · Quests

Quests on a map, pages as you drew them.

Chapters, quests and the lines between them, drawn on a map. Each quest's page is laid out in the screen builder and opens in the game exactly as you drew it.
