Scripted Rules

What problem does it solve?

This guide helps modders and developers define and review Victoria 3 scripted rule entries to ensure engine hook keys are accurate, consistent, and used as intended.

Core Features & Use Cases

• Define exact engine-hook keys such as treaty, war, and power bloc checks
• Provide explicit consumer-key guidance that specific mods or subsystems rely on
• Validate scope contracts and cross-reference with vanilla references and reusable helpers

Quick Start

Create or update a scripted_rules entry in common/scripted_rules/*.txt following the scope contracts and engine-hook patterns described above.
