Navigation Mesh Physics¶
Path-finding in Blender is based on the concept of navigation meshes <http://en.wikipedia.org/wiki/Navigation_mesh>. Now you can create navigation mesh for your level geometry directly in Blender and use it in Blender Game Engine (BGE) to get your actors to find path to the target and move along it. Besides path following, there are also a few other steering behaviors which can be assigned to the actor: seek and flee. Path-finding with navigation mesh is effective for big static obstacles. To enable actors to avoid small dynamic objects during their movement local obstacle avoidance can be used. If the obstacle simulation is enabled the actor will try to choose direction which is free of collision with obstacles on each frame during execution one of the steering behaviors.
Options¶
- NavMesh Copy Face Index
- Copies the navigation polygon index from the active face to selected faces.
- NavMesh New Face Index
- Adds a new navigation polygon index to selected faces.
- NavMesh Reset Index Values
- Assigns a new index to every faces.
- NavMesh Clear Data
- Removes the navigation data from the mesh.
