About
A Happy World is a psychological and analog horror mod that gradually unsettles an otherwise ordinary Minecraft world through unpredictable events and changes to the environment, interface, and sound. Exploration can reveal a custom, empty dimension with an End-like sky, no animals or villages, and unsettling builds such as ThisLooksLikeOld and Forgotten Threshold. A mysterious HAPPY sign, the Watcher and Unhappy entities, and unexplained lightning add to the sense that the world is watching the player. Events include a red-screen RUN sequence with custom music, a timed DARKNESS episode that blinds the player and removes nearby mobs, and STUCK, which shuffles the inventory before restoring it. The mod also uses simulated server-style messages and temporary interface effects as part of its horror presentation, without other players joining the world. Its horror effects can extend beyond the game, including creating files on the desktop and briefly accessing the webcam; the sources also warn of loud noises and epilepsy-related content.

No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Uses your webcam
- It can turn on a webcam to take pictures or video. Only in its files for Forge 1.20.1.
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Only in its files for Forge 1.20.1.
- Starts other programs
- It can start another program on your computer. Only in its files for Forge 1.20.1.
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Forge 1.20.1. See Privacy
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.2 latest files: the newest file for each Minecraft version and loader. Both are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.

Privacy
We found nothing it sends
We read its code without running it: it contacts no web address while you play.
It can open the camera app of your system. See Security
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of both files, for recent Minecraft versions. See each file in Releases
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign that AI was used to make it
We looked for AI tools in its texts, files, images and sounds and found none.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
