Whats the best way to make specific movements on the Y axis?

Questions & Answers
1

Right now im just using random range to do min height and max height but so far its not good enough I need specific coordinates so movement lines up properly with my model.

I was told to set up an array with a list of coordinates and have the random range pick from that but im not sure how to swap that out because im still new to coding this is what I got so far and I need 10 entry’s in the array for coordinates on the y axis.

For the most part I think I get it maybe just don’t know how to get the random range number to call the array number?

using UnityEngine;
using System.Collections;

public class Platform : MonoBehaviour
{
	#region Fields
	private float _targetHeight = 0f;
	
	private Vector3 _originalPosition;

Try something like this:

	public int[] MyArray;
	private int RandomNumb;

	// Use this for initialization
	void Start () {

		RandomNumb = Random.Range (0,10);

		Vector3 Pos = transform.position;

		Pos.y = MyArray[RandomNumb];

	}
