About this asset
🧠 Brains AI v2.0.0 — Massive Update!
This version brings a complete overhaul of the Brains AI system, making it more powerful, modular, and developer-friendly than ever.
Everything has been rebuilt with cleaner code, a better structure, and flexibility in mind, so you can use the tools not only inside Brains AI but also easily integrate them into your own systems.
✨ What’s New in v2.0.0
🧠 Brand-New Brain System
- Completely redesigned brains with smarter actions, cleaner logic, and a more modular structure.
🧹 Clean Custom Inspectors
- All components now feature clean, organized inspectors for faster setup and better readability.
📝 Commented Code + Tooltips Everywhere
- Every script is fully documented with summaries and tooltips, making it easy to understand and extend.
🆕 New Brain Type: Coward
- A unique behavior that prioritizes retreat and evasion when under threat.
👀 Better Movement Behaviors
- Characters can now jump across gaps using NavMeshLink connections.
- Characters can run backward while maintaining eye contact with their target.
📢 Noise & Alerts System
- Added a new Alarm Emitter component — works like explosions, screams, or sirens to alert specific or all agents to a location.
- Characters can easily make noise to alert others by simply calling CallAgents().
⚔️ Easy Randomized Attacks
- Support for both automatic and animation event/external attack calls.
- Simple random attack selection and random damage application for varied combat.
🎮 Take Control of Any Brain
- Instantly take control of any AI agent with a click during Play Mode using the Camera Follow system — perfect for testing.
🧠 Tactical Brain Upgrade
- Generates better tactical spots using a fixed 3D grid on the NavMesh surface for more realistic cover behaviors.
- Tactical brains now share information with other brains and can retreat intelligently like the Ranger brain.
🚨 Patrol System Improvements
- Smarter nearest-point detection and support for looping/back-and-forth modes.
- Patrol points are now numbered in the scene for easier editing.
🛠️ New Utility Methods
- Game Methods: One-shot audio and effect spawners for quick prototyping.
- Gizmos: Static drawing helpers for advanced visualization.
- Inspector: Custom EditorGUILayout helpers for cleaner editor tools.
🔧 More Flexible than Ever
All tools are not locked to Brains AI only — you can freely use the following systems in your own projects:
- Static Utility Methods
- Custom Gizmos
- Game Methods (Temp Audio / FX)
- FOV System
- Tactical Spots
- Patrol Paths
- …and more!
Everything is fully commented, so you’ll always know exactly what each part does and how to modify it for your needs.
🔥 Brains AI v2.0.0 is all about giving you a smarter, cleaner, and more adaptable AI foundation to build your projects on.
🧪 Fully tested in Unity 6 — everything works smoothly out of the box.
