Synchronize a GUI slider with a 3d Object?

Question

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);
  
     GUI.skin = Skin_power;
     if (GUI.Button(Rect(870,227,80,56),"")){
      audio.PlayOneShot(beep);
     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;
 
     animation.Sample();
     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;
 
  
  OnGUI()
  {
     // 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!
