Introduction

ModularMC is a TypeScript-based Regolith filter and successor to System Template. Instead of scattering files across directories by type (entities/, textures/, scripts/, etc.), ModularMC lets you organize files into logical modules based on functionality. A single module can contain an entity’s behavior file, textures, animations, scripts, and any other related assets.

Key Benefits

• Module organization: Group files by purpose, making projects easier to understand and maintain

• JSON templating: Dynamic content generation using TypeScript expressions inside JSON files

• Script compilation: Built-in Esbuild support for TypeScript/JavaScript compilation

• Familiar syntax: Uses familiar for most addon developers TypeScript syntax for configuration and templating

• Easy sharing: Modules can be copied between projects or shared with other developers
