EDIT: THE PROBLEM IS HIT.DISTANCE AS IT KEEPS CHANGING. I need it to be dynamic, but not be 2 things at once. Is there a way to make an object go all the way down on the Y axis until it hits the terrain? As well as rotate with the curves? I do not even know where to start with it , also I use javascript instead of C#, as I do not really know c#. Extra info: I am instantiating an object, but using the code below, it just starts flickering from the instantiated place to the area the code calls for. The code below is all that is attached to the instantiated object. Here is the code: function Update () { var HighestPointOfTerrain : int = 50; var hit : RaycastHit; if(Physics.Raycast(transform.position, -Vector3.up, hit)) { var distancetoground = hit.distance; var heightToAdd = transform.localScale.y; transform.position.y = HighestPointOfTerrain - distancetoground+ heightToAdd; } }

Try changing the line to Basically, what was happening was you were assuming that your object was always at a height of You my friend are a life saver! Thank you so much!

Then please mark my answer as correct (look for the check mark).

are you looking to put an actual object on the ground or is this like a targeting box or something along those lines that you want to simply project onto the terrain. if it's the second idea, you might want to look into projections. http://unity3d.com/support/documentation/Components/class-Projector.html The previous answer got what I needed. Works like a charm now :).

If you are looking for having it stay flush with the terrain, you will want to add a rigidbody component to the object.
There is one added already.
So then what is the problem? If the object has physics, it should stay on flush with the terrain automatically.
I don't know any other way of saying that it flickers in two places
By 'flickers' do you mean that is moving to multiple positions very rapidly?
I think the issue might be with the script moving the object to a bad location and then the physics engine pushes the object out of that location, the script puts it in another bad spot, and so on.
