NavMesh.FindClosestEdge

Parámetros

Valor de retorno

bool True si se encuentra un borde más cercano.

Descripción

Localice el borde NavMesh más cercano desde un punto en el 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.
