NavMeshPath.corners

Description

Corner points of the path. (Read Only)

Also known as "waypoints", the corners define the places along a path where it changes direction (ie, the path consists of a number of straight-line moves between corners).

// Calculate the length of a NavMeshPath. A character will
// typically move a slightly longer distance than this as a
// result of its steering behaviour.
function PathLength(path: AI.NavMeshPath) {
    // The length is implicitly zero if there aren't at least
    // two corners in the path.
    if (path.corners.Length < 2)
        return 0;

    var previousCorner = path.corners[0];
    var lengthSoFar = 0.0;

    // Calculate the total distance by adding up the lengths
    // of the straight lines between corners.
    for (var i = 1; i < path.corners.Length; i++) {
        var currentCorner = path.corners[i];
        lengthSoFar += Vector3.Distance(previousCorner, currentCorner);
        previousCorner = currentCorner;
    }

    return lengthSoFar;
