NavMeshObstacle.size

Description

The size of the obstacle, measured in the object's local space.

The size will be scaled by the transform's scale.

	// Fit a box shaped obstacle to the attached mesh

	function Start () {
		var obstacle : NavMeshObstacle = GetComponent.<NavMeshObstacle>();
		var mesh : Mesh = GetComponent.<MeshFilter>().mesh;

		obstacle.shape = NavMeshObstacleShape.Box;
		obstacle.size = mesh.bounds.size;
	}

public class ExampleClass : MonoBehaviour {
    void Start() {
        NavMeshObstacle obstacle = GetComponent<NavMeshObstacle>();
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        obstacle.shape = NavMeshObstacleShape.Box;
        obstacle.size = mesh.bounds.size;
    }
