How to assign slider to float: Spin, on a gameobject

Questions & Answers

Here is the Spin script attached to a circle object:

using UnityEngine;
using System.Collections;

public class Spin : MonoBehaviour {

	public float speed = 10f;

	// Update is called once per frame
	void Update () {

		transform.Rotate (Vector3.forward, speed * Time.deltaTime);

	}
}

I’ve dragged the GameObject (“Radar Main”) into the On Value Changed slot. For function, I choose Spin and a list comes up. I’ve tried different selections, but none of them control ‘speed’, the only public float/variable in the script. What am I missing? Thanks.

This is expected; you haven’t defined a function which accepts a float value. Try adding the following to your Spin class.

	public void SetSpeed(float speed)
	{
		this.speed = speed;
	}

That should adjust the speed as expected, but it’s not totally clear that’s what you’re intending. Either way I hope this helps you do what you’re trying to do.
