Why inventory tuning matters
A stable RP economy depends on scarcity, friction, and meaningful choices. Inventory rules (slots, weight, stack limits, metadata like durability/serials) are the levers that make those choices real. If everyone can carry everything, prices collapse and loops break. Tune inventory first, then iterate your prices, payouts, and sinks.

Models: Slots vs. Weight vs. Hybrid
Slots-only
- Simple cognitive model; each item = 1 slot or defined by size classes.
- Weak at differentiating heavy vs. light stacks; exploits via many tiny high-value items.
Weight-only
- Each item has a weight (usually grams). Players have
maxWeightper container. Strong realism; needs thoughtful defaults.
Hybrid (recommended)
- Global weight cap and slot cap. Prevents both micro‑item and mega‑item exploits. Works best for RP.
Tip: Keep numbers human‑readable. If you model in grams, use whole numbers (e.g.,
water = 500g) and round player caps (e.g.,maxWeight = 120,000).

Häufig gestellte Fragen
You recommend a hybrid weight and slot system. What are the drawbacks of using only weight or only slots for inventory management?
A slots-only system, where each item occupies a slot or a defined size class, struggles to differentiate between heavy and light items. This can lead to exploits where players carry numerous small, high-value items. A weight-only system, where each item has a weight and players have a maximum weight capacity, is more realistic but requires careful configuration of default weights. A hybrid system, combining global weight and slot caps, prevents both micro-item exploits (many small items) and mega-item exploits (a few very heavy items), making it a more balanced choice for roleplay servers.
How should I adjust the provided default weight and slot presets for my FiveM server?
The default presets provided are battle-tested starting points. After implementing them, monitor in-city telemetry for about a week. Observe player behavior, resource availability, and economic indicators. Based on this data, adjust the values by ±10–20% to fine-tune the balance to your specific server's needs. Consider factors like the availability of items, the rewards for different activities, and the desired level of scarcity.
If I'm using ESX, QBCore, or ox_inventory, how do I use the `items.lua` definitions provided?
The guide provides copy-pasteable `items.lua` definitions specifically designed for ESX, QBCore, and ox_inventory frameworks. Locate your existing `items.lua` file within your inventory script's directory. Carefully integrate the provided definitions, paying close attention to syntax and ensuring you don't overwrite or duplicate existing item definitions unintentionally. Remember to restart your server or inventory script after making changes for them to take effect. Always back up your original `items.lua` file before making modifications.
What makes inventory tuning important for a balanced roleplay economy in FiveM?
Inventory tuning, including managing slots, weight, stack limits, and item metadata, is crucial for creating a stable RP economy. These rules enforce scarcity, introduce friction, and force players to make meaningful choices about what they carry. If players can carry unlimited quantities of everything, it leads to price collapses and breaks economic loops. Tuning the inventory system is a foundational step before adjusting prices, payouts, and economic sinks.
