Snap to collider in editor script?

I have an editor window script with a button. When the button is pressed I would like an object, to move downwards until it meets a collider (where the object’s center stops).

Any ideas how I could do this?

Would I be able to use a raycast somehow?

Problem solved:

#pragma strict
class newwindow extends EditorWindow {

var objecttomove : GameObject;
var collisionobject : GameObject;
var shouldimove = true;

    @MenuItem ("Window/testeditor")
    static function Init () {
            // Get existing open window or if none, make a new one:        
            var window : newwindow  = ScriptableObject.CreateInstance.<newwindow>();         
            window.Show();
            }
function OnGUI() {


objecttomove = EditorGUILayout.ObjectField("Object: ",objecttomove, GameObject, true);
collisionobject = EditorGUILayout.ObjectField("collision object: ",collisionobject, GameObject, true);


if(GUILayout.Button("Move down")) {
move();
}
if(GUILayout.Button("reset move")) {
shouldimove = true;
}
}
function move() {
if (shouldimove == true) {
objecttomove.gameObject.transform.position.y = objecttomove.gameObject.transform.position.y-0.01;
if (objecttomove.gameObject.renderer.bounds.Intersects(collisionobject.gameObject.renderer.bounds)) {
shouldimove = false;
}
move();
}
}
}

…but you have to click the ‘reset move’ button after you move an object
