Description

This mod provides system-level window manipulation features.
Improper or malicious use may negatively affect user experience.
Use responsibly.

This is a script extension mod based on CustomNPCs Unofficial (1.20.1), designed to provide system-level operations that would otherwise require extensive use of Java.type.
While this mod does not involve any form of malware, some features are potentially risky.
It is strongly recommended that you only grant scripting permissions in CustomNPCs Unofficial to people you trust.

Current Status

If you are creating a Minecraft map with “fourth wall breaking” effects similar to Doki Doki Literature Club!, this mod may be a good fit for your project.

The original purpose of this mod is to prevent the misuse of importing system classes via CNPC to create external shell scripts, which may pose security risks.
This mod does not execute or rely on shell operations. All provided functions can be used directly within the native CNPC scripting environment after installation.
