YPM — Your PC Mine
A Fabric mod that lets you mess with your friends directly from a Minecraft server. Built for ARGs, horror maps, or just chaotic fun — you type a command, and something happens on their screen. Or their game. Or their PC.
⚠️ Must be installed on both server and client. Players without the mod will be kicked on join.
✨ What you can do
/ypm error <player> "Title" "Text" [freeze]
Pops a fake Windows error dialog on their screen. Add a freeze time to lock up their game first, then show it. Use | for line breaks.
/ypm errorspam <player> <count> "Title" "Text" [--random] [--minimize]
Floods their screen with fake error dialogs — up to 100 at once. Flags:
--random— randomizes dialog positions across the screen--minimize— minimizes Minecraft before spawning the dialogs
/ypm freeze <player> <time>
Freezes their game completely for a set time (e.g. 10s, 2m). Nothing works — no clicking, no moving, nothing.
/ypm windowshake <player> <time> <strength 1-10> [--noise] [--fullwindowed] [--restore]
Shakes their Minecraft window. Strength from 1 to 10. Optional flags:
--noise— random jerky movement instead of smooth waves--fullwindowed— stretches to fullscreen before shaking--restore— puts the window back where it was after
/ypm overlaytext <player> <time> <size 1-5|rdm> <scaleX|rdm> <scaleY|rdm> <color> "text" [--random] [--sound] [--mctext]
Renders text directly on their screen, over the game. Size from 1 (tiny) to 5 (huge), or rdm for random. Scale X/Y control stretch — rdm randomly squeezes one axis and stretches the other. Flags:
--random— places the text at a random position on screen--sound— plays a low tone when the text appears--mctext— uses the vanilla Minecraft font instead of the mod's font
Supports & color codes (&4, &c, etc.) and formatting codes (&l bold, &o italic, &n underline, &m strikethrough, &k obfuscated, &r reset) anywhere in the text. Use | for line breaks.
/ypm overlayspam <player> <count> <time> <size> <scaleX> <scaleY> <color> "text" [--random] [--sound]
Sends the overlay text repeatedly — <count> times with 100ms between each flash.
/ypm console <player> <time> <color> "text" [--screamer [<vol> [<seconds>]]] [--mctext]
Blacks out their entire screen and types the text line-by-line like a terminal. Lines appear one at a time, looping until time runs out. Use | to separate lines. Flags:
--screamer— plays a scream sound when it appears. Optional:<vol>(0.0–1.0) and<seconds>for how long the sound lasts--mctext— uses vanilla Minecraft font
Supports & color and formatting codes.
/ypm screamer <player> [<volume>] [<duration>]
Plays a raw scream sound directly on their client with no visual. Volume 0.0–1.0, duration in s/m format.
/ypm web <player> <url>
Opens a URL in their browser. While they're playing.
/ypm txt <player> "filename" "text"
Creates and opens a .txt file in Notepad with whatever you want it to say. Use | for line breaks.
/ypm minimize <player>
Minimizes their Minecraft window. Poof.
/ypm shutdown <player>
Shuts down their PC.
/ypm reboot <player>
Reboots their PC.
/ypm chat <player> "text" [--send] [--perspective]
Opens their chat and types text as if it's them. Flags:
--send— sends the message automatically--perspective— switches their camera view while typing
/ypm perspective <player>
Switches their camera between first and third person.
/ypm disclaimer <player>
Shows the YPM disclaimer screen to the player.
🔁 Interactive overlay — /ypmutil
/ypmutil overlaytext <overlay_to> <time> <size> <scaleX> <scaleY> <color> [chat_from] [--random] [--sound] [--mctext]
Starts an interactive overlay session. Whatever the designated player (chat_from, or the command executor by default) types in chat gets sent live as overlay text to overlay_to — instead of being posted in chat. Supports player names, comma-separated lists, or r<N> for radius (e.g. r20 = all players within 20 blocks).
Useful for ARGs where a "system" character types messages that appear directly on someone's screen in real time.
/ypmutil stop [<player>]
Ends the active overlay session. Without an argument, stops your own session.
🛡️ Player protection — /ypmconfig
Players can restrict what the operator is allowed to do on their machine:
/ypmconfig canopenweb <true|false>
Block the operator from opening URLs in the browser. When blocked, a fake browser window appears inside the game instead.
/ypmconfig canshutdown <true|false>
Block shutdown and reboot commands. When blocked, a fake shutdown/reboot screen appears inside the game — the PC is not touched.
/ypmconfig enablesafemode <true|false>
Enable Safe Mode — the most complete protection. All out-of-game actions (browser, Notepad, shutdown) are fully simulated inside Minecraft. Nothing reaches the real OS.
Running /ypmconfig with no arguments shows your current settings.
📡 Operator feedback
When you run any /ypm command, the server tells you the mode each player is in:
[YPM] Error sent to 3 player(s) | Normal: 2, SafeMode: 1
So if you're running an ARG with a group, you always know who gets the real effect and who is in safe mode.
🎭 Made for ARGs, horror maps, and pranks between friends on private servers. Please don't be evil.
