In this tutorial I cover advanced AI navigation editing without recompiling the map. You will learn how to add air nodes for flying and swimming NPCs, Strider air hint nodes for proper movement and crouching, and how to simulate free roaming gunships and helicopters using path tracks and embedded Lua. The workflow uses Hammer Editor, VMF decompiling, and BSP entity patching to bring smarter AI behavior to existing maps.
