orizontal slider to control a plane's y transform variable

Hey all,

Here is what I’m trying to do.

I’m attempting to use a Horizontal slider to control a plane’s y transform variable

here is what I have so far.

var hSliderValue : float = 0.0;
var hv: Vector3;
var horizdisplaytext: String;
var crazy: Transform;
var plane: GameObject;

function Start(){
crazy = gameObject.GetComponet(Transform);
crazy = gameObject.transform;
}

function Update(){ 
			hv = Vector3.up;
			var horizdisplay: float=hv.magnitude;
			horizdisplaytext = horizdisplay.ToString();
			}

function OnGUI () {
    hSliderValue = GUILayout.HorizontalSlider (hSliderValue, 0.0, 10.0);
    GUILayout.Label("This text makes just space");        
    GUI.Box(Rect(Screen.width - 110,Screen.height *0.8,100,50), hSliderValue + " TEST");

}

The code isn’t working as right now im having trouble linking the slider with the transform variable

any help would be great. THANKS!

BTW. the plane is taged as Plane

Here is a few modifications to your code so that the slider will move a plane up and down. Note a plane is one-sided, so if you lift it so that you are looking at the bottom, the plane will disappear. I’ve set the value range from -10 to 10:

#pragma strict

var hSliderValue : float = 0.0;
var hv: Vector3;
var horizdisplaytext: String;

private var crazy: Transform;
private var plane: GameObject;
private var startY : float; 
   
function Start(){
//crazy = gameObject.GetComponet(Transform);
crazy = gameObject.transform;
plane = GameObject.Find("Plane");
startY = plane.transform.position.y;
}
 
function Update(){ 
         hv = Vector3.up;
         var horizdisplay: float=hv.magnitude;
         horizdisplaytext = horizdisplay.ToString();
         }
 
function OnGUI () {
    hSliderValue = GUILayout.HorizontalSlider (hSliderValue, -10.0, 10.0);
    plane.transform.position.y = startY + hSliderValue;
    GUILayout.Label("This text makes just space");        
    GUI.Box(Rect(Screen.width - 110,Screen.height *0.8,100,50), hSliderValue + " TEST");
 
}
