NavMeshAgent.Raycast

Parámetros

Valor de retorno

bool True if there is an obstacle between the agent and the target position, otherwise false.

Descripción

Trace a straight path 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.
