public class spinner : MonoBehaviour {

public float reducer;

public float multiplier = 1;

bool round1 = false;

public bool isStoped = false;

void Start ()

{

// Update is called once per frameQ

void FixedUpdate () {

Needle Script:

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.UI;

public class needle : MonoBehaviour {

public spinner _spinner;

public Text scoretext;

// Use this for initialization

void Start () {

}

// Update is called once per frame

void Update () {

}

void OnTriggerStay2D(Collider2D col){

if (!_spinner.isStoped)

return;

scoretext.text = col.gameObject.name;

}

}

how to use slider in unity

first goto -> create -> UI -> slider and create a slider this will create a canvas if not already created.

create a script and attach it to any gameobject (payer or camera) or just put the code in any script
assing the public slider variable in inspector by draging the slider component from hierarchy to inspector as shown below.

now run the code after running you will notice the slider value will change to 10 as written in code.
