DatapacksJava
Common Signals
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Common Signals
📚 Common Signals is a library datapack that provides signals through function tags to help developers optimize their datapacks.
The initial goal is to prevent multiple datapacks from ticking the same inefficient @e selectors.
Available Signals 📡
🔔 Common Signals provides several function tags that developers can hook into:
#common_signals:signals/on_new_item: 📦 Triggered when a new item entity is detected in the world (not having thecommon_signals.checkedtag)
Feel free to suggest new signals!
Usage for Developers 🔧
- 📦 Create a datapack that depends on Common Signals
- ➕ Add functions to the signal tags you want to listen to
- ⚡ Your functions will be called whenever those signals are triggered
