From wiki: A navigation mesh, or navmesh, is an abstract data structure used in artificial intelligence applications to aid agents in path-finding through large spaces.

A navigation mesh, or navmesh, is an abstract data structure used in artificial intelligence applications to aid agents in path-finding through large spaces. Meshes that do not map to static obstacles in the environment that they model, offer the additional advantage that agents with access to the mesh will not consider these obstacles in path-finding, reducing computational effort and making collision detection between agents and static obstacles moot. Meshes are typically implemented as graphs, opening their use to a large number of algorithms defined on these structures.

How to create a NavMeshAgent Pathfinder for 3D "flying" enemies in Unity

Is there a way to code in NavMeshAgent to work in 'air' inside Unity such that an enemy AI can follow the character up and down without the need to create a floor or multiple floors? My code only works for 3D on 'ground' characters and not on…

In unity, baking a nav mesh at runtime for a second time causes the navmesh to only partially build

I am currently designing a maze game in unity and have some enemy AI which chases players around the maze. If the player gets to a certain tile on the maze it'll generate a new maze with slightly larger dimensions. I've been using the unity AI…

SetDestination() sometimes does not work on NavMeshAgent with incomplete paths

In most cases, when I call SetDestination() on a NavMeshAgent to go to a location that no complete path exists, the agent will go as close to the location as possible and then stop. When I try to run SetDestination() continuously in an agent's…
