In this indie game dev tutorial for Godot 4, we’ll walk through a beginner-friendly setup for 3D pathfinding using NavigationRegion3D and NavigationAgent3D.

We apply the NavigationRegion3D directly to our GridMap-based world, allowing the navigation system to understand the layout of walkable areas. Then, we add a NavigationAgent3D to an enemy character so it can move around the world using simple, built-in pathfinding.

This is part of our ongoing Godot 4 game project and a great starting point if you’re building an indie 3D game and want to give your enemies or NPCs some basic movement logic.
