| Name | Description |
|---|---|
| targetPosition | The desired end position of movement. |
| hit | Holds the properties of the resulting unblocked position. |
boolean - True If terminated before reaching target position. Otherwise returns false.
Trace movement towards a target postion in the NavMesh. Without moving the agent.
This function follows the path of a "ray" between the agent's position and the specified target position. If an obstruction is encountered along the line then a true value is returned and the position and other details of the obstructing object are stored in the hit parameter. This can be used to check if there is a clear shot or line of sight between a character and a target object. This function is preferable to the similar Physics.Raycast because the line tracing is performed in a simpler way using the navmesh and has a lower processing overhead.
