Unity automatic pathfinding

First create a simple scenario .
The second step , Choose the ground and built roads , take Static Set to Navigation Static Check box ,unity The navigation grid will be generated by the selected object ：

The third step ： Select... In the menu bar Window—>Navigation command , eject Navgation View . And then choose Navgation In the view Bake Button generate navigation grid , Then its walkable floor will turn blue and transparent .


Step four ： Create a movable object , Here we use a cube instead of , To add NavMesh Agent Components .

Introduction to basic component information
Base offset： Offset from the ground
speed ： Movement speed
Angular Speed： Corner speed , Turning speed angular velocity ： Maximum speed （ degree / second ）.
Acceleration ： The acceleration , At startup Maximum acceleration .
Stopping Distance： Stop distance , Braking distance ： Braking distance . The distance to the destination is less than this value , Agent decelerates .
Auto Traverse OffMesh Link ： Automatic traversal OffMesh link ： Automatically move and close OffMeshLinks
Auto Repath： Automatic rerouting ： If the existing part has expired , Get a new path .
Height： Height ： The height of the agent （ Used to debug graphics ）.
Base offset： Basic offset ： The vertical offset of the collision geometry from the actual geometry .
Obstacle Avoidance Type ： Obstacle avoidance type ： Quality level of avoidance .
NavMesh Walkable： Navigation grid walk ： Specify the type of navigation grid layer that the agent can traverse . This parameter has a great effect , In the following example, you can use .

Step five Add move script for Cube , Click the mouse to move it to the specified location .
