NavMeshAgent.destination

Descripción

Gets or attempts to set the destination of the agent in world-space units.

Getting:

Returns the destination set for this agent.

• If a destination is set but the path is not yet processed the position returned will be valid navmesh position that's closest to the previously set position.
• If the agent has no path or requested path - returns the agents position on the navmesh.
• If the agent is not mapped to the navmesh (e.g. scene has no navmesh) - returns a position at infinity.

Setting:

Requests the agent to move to the valid navmesh position that's closest to the requested destination.

• The path result may not become available until after a few frames. Use pathPending to query for outstanding results.
• If it's not possible to find a valid nearby navmesh position (e.g. scene has no navmesh) no path is requested. Use SetDestination and check return value if you need to handle this case explicitly.
