🎭 Actor (ActorMC)

Ever wanted to control a Minecraft player through code — cleanly, smoothly, and server-compatible?

Actor is a modding API / developer library that lets you drive a player like they’re actually pressing keys and clicking a mouse 🖱️⌨️
Perfect for automation, testing, TAS tooling, and “player-as-a-program” ideas.


👤 For Players

⚠️ This mod alone does not do anything by itself.

Actor is a library dependency for other mods.
If you install only Actor, you won’t see any new items, commands, or gameplay changes.

✅ Install Actor if:

  • Another mod requires it
  • You’re a developer building with it 🧑‍💻

🧑‍💻 For Developers

📚 Docs / Setup / API Reference:
👉 https://docs.actormc.net/

Supported everywhere you’d expect:

  • 🧵 Fabric
  • 🪡 Quilt
  • 🔥 Forge
  • ⚡ NeoForge

🚀 What you can build with Actor

With Actor, you can create mods/tools that do stuff like:

  • 🤖 Auto-play systems that behave like real players
  • ⏱️ TAS / deterministic input playback
  • 🧪 Automated testing bots for mechanics, farms, redstone, combat, etc.
  • 🧭 Scripted movement + rotations (perfect for precision tasks)
  • 🧱 Automated block interactions (place/use/attack) without breaking game rules
  • 🎮 Advanced “macro” style tooling — but coded, structured, and consistent

If it looks like something a player could do… Actor helps you do it programmatically ✅


✨ Why Actor?

🔥 Feels native
Your Actor-driven player behaves like a real client would.

🧠 Clean API
Built for developers: easy to use, easy to extend, easy to reason about.

🌍 Server-compatible mindset
Actor respects real gameplay limitations — no weird desync-y behavior.

⏲️ Tick-based control
Write logic that runs naturally with the game loop.


❤️ Made for builders who code

If your mod idea involves “What if a player could…”
Actor is the foundation that makes it real. 🎮⚙️
