How make an object move to the player's position and then land in the ground?

This is for a supply drone that will arrive when the player hits a button.

I got the approach code but I have no idea how to make it land

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class SupplyDrop : MonoBehaviour {
5.    public Transform dropzone;
6.    public float speed;
7.    void Update() {
8.        float step = speed * Time.deltaTime;
9.        transform.position = Vector3.MoveTowards(transform.position, dropzone.position, step);
10.    }
11. }

 

Since you already have the code for it approaching the drop zone, can you not check the distance between and the drone and the dropzone position then if its within a certain range then proceed to move downwards

So i advise looking up Vector3.Distance , and a raycast to check if u hit the floor to stop moving

 

I like the raycast idea i didn't think of that. So I will have a raycast set to 5 so when it hits the floor collider, i just disable the script. Also use for my helicopter landing. Alright I'm set...

 

Instead of making your dropzone position up

You could also just put your drop zones at the actual landing spot, but don't start setting your Y value until your X and Z values actually reach the drop zone.

Or you could even make a DropZone class for your drop zones that you would "GetComponent<DropZone>()" (only once to get the reference and hold it), and then your movement code would have access to whatever properties you had in it, like a "float safeEntryHeightOffset;" that your movement code would use until it was directly above the drop zone, and then start flying directly down to the proper position.
