: Before every change, save a "vanilla" copy of your files. This allows you to revert in seconds if a new custom bridge breaks your server. Whether you are looking to build a massive PvP arena or just give your players a little more stamina, mastering JSON is the first step to truly "owning" your DayZ world. Would you like a specific

Preparing a review for DayZ JSON files (typically used for configuring types, events, spawnable types, economy, and game settings) requires a structured approach. Because these files dictate the core "loot economy" and gameplay loop, a review must focus on balance, syntax, and performance. Here is a comprehensive guide and template for reviewing DayZ JSON files.

Phase 1: Syntax & Structural Integrity Before diving into gameplay balance, you must ensure the files won't cause the server to crash or fail to load. 1. JSON Validity

Trailing Commas: JSON does not support trailing commas (e.g., "item", ). Ensure the last item in a list has no comma. Brackets: Check for missing opening/closing braces {} or brackets [] . Data Types: Ensure values are the correct type (e.g., nominal should be an integer, lifetime should be a number/float).

2. Class Names

Typos: Check for misspelled class names (e.g., M4A1 vs M4A1_Gun ). A misspelled class will simply be ignored by the engine, resulting in items not spawning. Deprecated Items: Are you trying to spawn items that have been removed from the game files in the current patch?

3. Duplicate Entries

Scan types.xml (or JSON equivalent) for duplicate class names. If an item is listed twice, the last entry usually overwrites the previous one, leading to unpredictable spawn rates.

Phase 2: Economy & Balance (The "Math" Check) This is the most critical part for gameplay feel. 1. Global Limits vs. Nominal Values

Formula: The nominal value (how many should exist on the map) should never exceed the quantmin + quantmax logic if items are consumable, but strictly, nominal should be logical compared to player count. The "Restock" Issue: Check the restock timer. If set to -1 or a very high number, loot will stop spawning once the nominal count is reached, and never respawn until a player picks it up. Rarity Scaling:

Common Items: High nominal , low lifetime (if they are trash). Rare Items (M4, SVD): Low nominal , very high lifetime (so they don't despawn instantly if dropped). Check: Is the sum of all nominal values appropriate for your server slot count? (e.g., 50 players vs. 60 players require different loot pools).
