# CS Cases<\/p>\n
A CS:GO-style case opening mod for Minecraft. Place a case, use the matching key, watch the reel spin, and claim your loot.<\/p>\n
## Features<\/p>\n
– **Authentic opening flow** \u2014 preview a case’s contents before you commit, watch a reel-style reveal animation with the classic case-unlock sound, then explicitly **Claim** your reward or press **ESC** to drop it on the ground.
\n– **Five-tier rarity rolls** with weighted probabilities and the familiar CS color coding: Mil-Spec blue \u2192 Restricted purple \u2192 Classified pink \u2192 Covert red \u2192 Rare Special gold.
\n– **Fully data-driven** \u2014 every case is a JSON file in a datapack. Add, edit, or rebrand cases on a server or in a single world without recompiling, repackaging, or shipping a client-side resource pack.
\n– **Real item stacks as rewards** \u2014 a reward entry is anything `\/give` accepts. Stack sizes, enchantments, custom names, lore, attribute modifiers, dyed leather, any registered data component, all of it.
\n– **Wrong-key protection** \u2014 keys are bound to specific cases via a data component. Using a key on a case it doesn’t fit shows *”This key does not fit this case.”* in the action bar; the key is not consumed.
\n– **Multiplayer-ready** \u2014 the server pushes its full case registry to every client on join and after `\/reload`, so dedicated-server players see exactly what the server has loaded with zero client-side setup.
\n– **Hot reload** \u2014 `\/reload` re-parses every case from disk. Valid changes apply immediately. Malformed files are skipped with a clear warning in the server log instead of crashing the world.
\n– **In-game config screen** integrated with the Mods menu.<\/p>\n
## How it works<\/p>\n
1. Grab a **Case** and a matching **Case Key** from the creative tab \u2014 the tab automatically lists one of each per loaded case.
\n2. Place the case. Right-click it with the matching key to open the **preview screen** showing all possible rewards, grouped by tier.
\n3. Hit **Open** to consume the key and start the reveal animation. Press **ESC** during the animation to skip straight to the reward screen.
\n4. On the reward screen, click **Claim** to take the item, or press **ESC** to let it drop at your feet.<\/p>\n
## Adding your own cases<\/p>\n
Drop a JSON file at:<\/p>\n
“` Minimal example:<\/p>\n “`json Tier weights are normalised at roll time, so any positive numbers work \u2014 `1` and `99` is the same as `1%` \/ `99%`. Items can be either a bare id (count 1, no components) or a full `{ “id”: …, “count”: …, “components”: { … } }` object.<\/p>\n Hand out your custom cases via the creative tab or:<\/p>\n “` The full datapack format reference, including every supported field and validation rule, lives at `docs\/datapack-cases.md` in the source repository.<\/p>\n ## Built-in content<\/p>\n The mod ships one default case \u2014 the **Starter Case** \u2014 built with the same datapack machinery as everything else, so its JSON doubles as a working example.<\/p>\n ## Requirements<\/p>\n – **Minecraft** 26.1.2 NeoForge only. Not compatible with Forge or Fabric.<\/p>\n Both single-player and multiplayer (dedicated server) are supported. Custom cases are server-authoritative \u2014 install the mod on the server and on every connecting client, and define your cases via datapacks on the server.<\/p>\n ## License<\/p>\n All Rights Reserved.<\/p>\n","protected":false},"excerpt":{"rendered":" CS:GO-style case opening for Minecraft.
