The /reload Command for Datapacks and Functions
The primary way to reload content in Minecraft is using the /reload command. This command refreshes all datapacks, functions, loot tables, advancements, and recipes without requiring you to restart your world or server.
To use it, simply type:
/reload
You’ll need operator permissions (cheats enabled) to run this command. When executed, you’ll see a confirmation message showing how many datapacks were reloaded.
What Gets Reloaded
The /reload command specifically refreshes:
- All datapacks in your world
- Custom functions you’ve created
- Loot tables and recipes
- Advancements and tags
- Predicates and item modifiers
This makes it incredibly useful when you’re developing custom content or installing new datapacks mid-game.
Reloading Chunks with F3 + A
For visual glitches or chunk loading issues, you’ll want to reload chunks instead. Press F3 + A to force all visible chunks to reload. This fixes rendering problems like missing textures, lighting errors, or blocks that appear incorrectly.
This keyboard shortcut works in both Java Edition single-player and multiplayer, though it only affects what you can see on your screen.
Server-Specific Reloading
On dedicated servers, the /reload command works the same way but affects all players. Server administrators often use this when updating datapacks or functions without restarting the entire server, which saves time and keeps players connected.
Some server plugins may also provide additional reload commands for their specific features, but the vanilla /reload command handles all standard Minecraft content.
Whether you’re testing custom functions or fixing visual glitches, these reload methods will keep your Minecraft experience running smoothly without losing progress.
TL;DR
Use /reload to refresh datapacks and functions, or F3 + A to reload visible chunks and fix rendering issues.
