What is nav mesh agent?

Nav mesh agent is a tool in game development that provides an artificial intelligence system for autonomous agent movement. It is a pathfinding technology that allows characters in a game to move around a level. The Nav mesh agent is a component that is added to game objects or characters to enable them to move within a game world. The agent uses a navigation mesh, which is a simplified representation of the game world that is used for pathfinding. The nav mesh agent can navigate around obstacles and adjust its path according to changes in the environment. It is commonly used in games to create non-player characters (NPCs) that are able to navigate through complex environments, such as buildings or outdoor environments. Nav mesh agent is a popular tool in game development because of its ease of use, flexibility, and ability to create realistic movement for game characters.
