Title: Getting current position in Slider?
Post by: pretender on April 27, 2014, 04:55:12 AM
Hi!

I have a level progress bar with UISlider setup. As time progresses (level) slider moves to the end, I want to be able to mark certain points on the slider, for example sections of the level that are reached. In order to do this I need position of the right edge of the slider bar, then I should be able to instantiate a sprite over slider to mark that position.

Any ideas how to do it? Thanks!

Make a new script, put this code into it ( In this case the file named : MyTestScript_1 ) :

  1. using UnityEngine;
  2. using System.Collections;
  3.  
  4. public class MyTestScript_1 : MonoBehaviour {
  5.  
  6.  
  7.         public UISlider slider_1 ;
  8.  
  9.         void Update ()
  10.         {
  11.                 print (slider_1.sliderValue);
  12.         }
  13. }
  14.  

Drag that script into the Slider object .

Drag the slider object from the hierarchy tab to the slider_1 value which shows in the Inspector  (Because it declared as public ) .

Play the scene and it will print the value of it while you play in it every frame .

Thanks for looking into this although i dont need a value of slider but the position of of a point that is on the right side of the slider (uisprite that is moving) that i can use to instantiate another sprite to mark position on the slider.

Because if so, all you need to do is :

1.Make a new script .

2.Attach it to the "Thumb" object ( Which is holding that sprite ) .

3.Open this script and put into the Update() function this line :
      print (transform.position);
This line however will print the values with only one digit after the decimal point, If you want it to be more precise you should use these three lines :
      print ("X position : "+transform.position.x);
      print ("Y position : "+transform.position.y);
      print ("Z position : "+transform.position.z);

But some object has to have the sprite on it, it's not just sitting there...

If you click on any sprite in edit view you will notice green handles, i need that in run time

The thumb doesn't need to be visible. You can simply create a plain game object and set that to be the thumb. You can then retrieve its position like you would with any game object.

Ok i will try that, but anyhow i would like to know how you draw handles on edges of the sprite, how do you get that position?
