🚨 Just unlocked Spring AI → Ollama function calling in session 3 of my LLM game dev series.
All built in Java, live-coded.
Let me break it down 🧵

Had to upgrade to Spring AI 1.1.0-SNAPSHOT due to function call exceptions.
✅ That fixed it.
✅ Function calls are now routed cleanly to Ollama (LLaMA 3.2).

New in this session:
🎮 Health + mana bar logic
🎮 AI-driven success/failure outcomes
🎮 Inventory system (partially wired)
☠️ The player can now lose!

The big win?
AI doesn't just write the story — it calls Java functions to alter game state.
LLMs are finally doing things, not just saying them.
