Hello! I just need some help with an elevator script. I am truing to make a platform go up, then go back down then back up then back down etc etc. What should I do? Here is my script:

`using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ElevatorMove : MonoBehaviour {

public float speed1 = 100;

// Use this for initialization
void move () {
	if (transform.position.y <= 100 )  {
	transform.Translate (Vector3.up * Time.deltaTime * speed1);
	}	if (transform.position.y >= 100 )  {
		transform.Translate (Vector3.down * Time.deltaTime * speed1);
	}
}

// Update is called once per frame
void Update () {
	move ();
}

}`

Thanks!

What’s the problem exactly?

I’m assuming the platform doesn’t move, or does very very quickly.

You need to change both 100’s, to something such as:

void move () 
{ 
if (transform.position.y <= 150 ) 
	{ 
	transform.Translate (Vector3.up * Time.deltaTime * speed1); 
	} 
if (transform.position.y >= 50 ) 
	{ 
		transform.Translate (Vector3.down * Time.deltaTime * speed1); 
	} 
}

This way it should move between 50 and 150 on the y axis.

I would structure it like this… I think this will work:

// declare this and initialize outside your function
Vector3	moveDirection = Vector3.up; // *assuming your platform starts at the bottom

void move () 
{ 
	if (transform.position.y >= 150 ) 
	{ 
		moveDirection = Vector3.down; 
	} 
	elseif (transform.position.y <= 50 ) 
	{ 
		moveDirection = Vector3.up;
	} 
	// implicit else... if it's in between, it should keep moving in the same direction it last was...
	
	transform.Translate (moveDirection * Time.deltaTime * speed1);
}
