Game Logic & AI Behavior

Tools for writing game code, implementing NPC behavior, and building AI systems. From coding agents that help write scripts to frameworks for emergent AI behavior.

Writing game code and implementing AI behavior is where your game comes to life. AI coding agents can help write scripts, debug issues, and optimize performance, while behavior frameworks enable emergent NPC intelligence without hand-coding every interaction.
