FollowerEntity, how to make fast agent stick to navmesh?

• A* version: latest
• Unity version: 6.3

Currently my agents move under navmesh when going on fairly fast speed on incline or drop in decline surfaces.

There’s no built in way to handle this directly but I’d turn off gravity altogether and use a suggestion like this from Aron:

Hi

This is by design. The NavmeshClamp component is only intended to clamp the agent on the XZ axes.

Typically, the navmesh is not accurate enough on the Y axis to use for ground collision. You’re usually better off using Physics.Raycast or something similar.

If you really want to, you can use:

var nn = NearestNodeConstraint.Walkable;
nn.distanceMetric = DistanceMetric.ClosestAsSeenFromAboveSoft();
var nearest = AstarPath.active.GetNearest(transform.position, nn);
if (nearest.node != null) {
    transform.position = nearest.position;
}
