Move up gameobject from ground ?

Hello , i have a script for align to coin from ground or some objects..

Here is a code ;

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class raycast2 : MonoBehaviour
6. {
7.      Rigidbody rb;
8.  
9.     void Start()
10.     {
11.         rb = GetComponent<Rigidbody>();
12.     }
13.  
14.     void FixedUpdate()
15.     {
16.         RaycastHit hit;
17.         if (Physics.Raycast(transform.position, -Vector3.up, out hit))
18.         {
19.          
20.         }
21.  
22.         if (hit.distance <= 2.0f)
23.         {
24.             rb.velocity = transform.up * 150 * Time.deltaTime;
25.         }
26.         else if (hit.distance >= 2.0f)
27.         {
28.             rb.velocity = -transform.up * 150 * Time.deltaTime;
29.         }
30.     }
31. }
32.  

But i have a problem, i cant set same transform position. It has vibration. what can i do please help me.

 

If you want it to snap to the ground, just assign it to the right height above the ground and set the velocity to zero.

IF you want it to move towards the ground, when it arrives at the ground (either going down to or up from), then stop setting the velocity nonzero. NOTE: it will NEVER be equal to 2.0: you cannot test floating point equality, so you need to sense it going from above to below.

NOTE: gravity may continue to make it fall. If so, turn off gravity on that Rigidbody.

 

Thank u for reply, It is true.. But during the game, I instantiate objects that sometimes moving.. Also different in height. When objects are in motion, they have to lift it up instead of passing through gold. After the object comes out from under it, it must return to its old place according to the height of the ground. I recorded video for understand me. Sorry for bad english

 

I'm actually not sure what you're trying to do. I recommend working through some more Youtube tutorials on games that are similar to your game, perhaps that can help you understand the problem better.

 

Thank you bro
