Synchronize a GUI slider with a 3d Object?

Hello everyone,

I’m trying to make a Drill with some interactive buttons as exercise to learn Unity. I made one button to activated the drill so you can see the tool spinning and a slider to control the speed in the GUI.

But I have problems trying to synchronize a GUI slider with a 3d Object “VariableSpeedAdjuster” with animation attached , so when the GUI slider is moving the 3d object too.

I made one script for the GUI buttons with a Slider and other for the 3d Object “VariableSpeedAdjuster” and finally another for the rotor or motor.

I’m trying to get to work my script, but I can’t.

Please any advice is more than welcome. Thanks in advance

Script Number 1
GUI & Slider Script.

static var triggerGo : int;
static var cameraGo : int;
static var vSliderValue : float = 0.0;
var vthumbStyle : GUIStyle;
var vsliderStyle : GUIStyle;
var Skin_power : GUISkin; 
 var beep : AudioClip;

function OnGUI (){

 	vSliderValue = GUI.VerticalSlider(Rect (887.5, 10, 50, 203), vSliderValue, -1500.0, -100.0,vsliderStyle,vthumbStyle); = Skin_power;
	if (GUI.Button(Rect(870,227,80,56),"")){
	triggerGo = (triggerGo + 1) % 2;

Script Number 2
And this is my other Script for the 3D object to be interact with my GUI Slider.

static var vSliderValue : int; 
var myAnimation : AnimationState;

function Start(){
    myAnimation = animation["VariableSpeedAdjuster"];

function LateUpdate() {
    myAnimation.time = vSliderValue;
    myAnimation.enabled = true;

    myAnimation.enabled = false;

Script Number 3
Motor or Rotor

function Update () {
amtToMove =buttonsGUI. vSliderValue * Time.deltaTime;
if (buttonsGUI .triggerGo == 1){
transform.Rotate(0,buttonsGUI. vSliderValue * Time.deltaTime,0);



I have little problem reading the script code, but here is a simple example on how you can do it:

private float m_currentValue    = 0.0f;
private float m_topValue        = 1.0f;
private float m_bottomValue     = 0.0f;

private Vector3 m_offPosition   = new Vector(0.0f, 0.0f, 0.0f);
private Vector3 m_onPosition    = new Vector(1.0f, 1.0f, 1.0f);

public GameObject m_3dObjectSlider = null;

    // Slider goes between 0.0 and 1.0, or you can see it as 0% to 100%
    m_currentValue = GUI.VerticalSlider(position, m_currentValue, m_topValue, m_bottomValue);
    m_3dObjectSlider.transform.Position = Vector3.Lerp(m_offPosition, m_onPosition, m_currentValue);    

So, I setup the slider GUI object to slide between 0.0 and 1.0.
And I use this value to Lerp the position of the 3d object. Now, I don’t know the exact
positions for the object, so I just put in some values, that you need to change.

But as you pull the slider in any direction, the 3d object should also slide between these two vectors.

I haven’t tested this code, its just a example, but I hope you can see the idea behind it and change the code around until it works for you and your project.

Good luck!
