NavMesh.FindClosestEdge

파라미터

반환

bool True if the nearest edge is found.

설명

Locate the closest NavMesh edge from a point on the NavMesh.

The returned NavMeshHit object contains the position and details of the nearest point on the nearest edge of the navmesh. This can be used to query how much extra space there is around the agent.

bool True if the nearest edge is found.

설명

Locate the closest NavMesh edge from a point on the NavMesh, subject to the constraints of the filter argument.

The returned NavMeshHit object contains the position and details of the nearest point on the nearest edge of the NavMesh. This can be used to query how much extra space there is around the agent.
