MG Dynamic Navigation – Demo Project (UE5.7)

About This Demo

This project demonstrates how to use the MG Dynamic Navigation (MGDN) plugin inside a real Unreal Engine level.
It shows how AI can navigate reliably on moving platforms using voxel grids, dynamic local-space pathfinding, and spline-based motion.

Original Plugin: https://github.com/cem-akkaya/MGDynamicNavigation

The demo includes:

• A sample moving ship platform with an MGDN Nav Volume
• A baked voxel grid stored in a MGDNNavDataAsset
• Example AI characters using MoveToLocationMGDNAsync
• Debug tools to visualize walkable voxels and path splines
• Example avoidance behavior and re-pathing

If you encounter any issues, please open an issue on the plugin repository.
Feel free to contribute!

How to Use the Demo

1. Download or clone this repository.
2. Right-click the .uproject → Generate Project Files.
3. Build the project using Visual Studio or Rider.
4. Open in Unreal Engine
5. Ensure MG Dynamic Navigation plugin is enabled.
6. Open the demo map and Play In Editor.

All demo logic is inside:

• BP_MGDN_AICharacter (AI example)
• BP_MGDN_MovingShip (platform setup)
• MGDNNavVolume component + data asset
• Level Blueprint (simple test triggers)

Inside the Demo Project

Demo Level

The included level contains:

• A large moving ship actor with an MGDN Nav Volume
• Walkable areas generated via voxel grid bake
• AI that walks, avoids other pawns, and adapts to platform movement
• Buttons & triggers to command example AI movement
• Visualization widgets to inspect voxel data and splines

Navigation Flow in Demo

1. Platform has MGDN Nav Volume
2. Volume uses Bake Grid to generate walkable voxel asset
3. At runtime, AI calls:
4. MGDN creates a spline path that moves with the platform
5. AI follows the path smoothly even if the ship moves or rotates
6. Optional avoidance injects detour points dynamically
