Question by Cookiemonster04 · Sep 28, 2019 at 02:52 AM · 2dhorizontal

how to move a gameobject's x position when another gameobject's x position is being moved?

My problem is I have a circle that is not moving along with a box x position(haven't worked on any artwork yet trying to get the gameplay working first) when the circle lands on the box & I move the box x position the circle stays where it is & falls when it isn't touching the box anymore. I want to move it along with the box from where it landed with out it having to be a child if possible.

 public bool touching;
 public GameObject box;
 Rigidbody2D rb;

 void Start()
 {
     rb = GetComponent<Rigidbody2D>();
 }

 void OnCollisionEnter2D(Collision2D col)
 {
     if (col.gameObject.tag == "Box")
     {
         touching = true;
         rb.constraits = RigidbodyConstraits2D.FreezeRotation;
     }
 }

 void Update()
 {
     if (touching)
     {
         Vector2 pos = transform.position;
         pos.x = box.transform.position.x  - pos.x;
     }
 }

I dont get exactly what are you asking (confused with you explanation... :D)

Why not just call a function (that moves the circle) when move the box?

Like @tormentoarmagedoom , I am also confused with your explanation, but looking at the last line of your code where you apply box.transform.position.x - pos.x to pos.x is really just applying the length between the 2 objects on the x axis and not giving you the correct x value in world space.

You want to get the circle’s x position relative to the box’s x position when the circle lands on the box and to do that without being a child you just save it when the collision happens:

 float relativeXPos;
 
 void OnCollisionEnter2D(Collision2D col)
 {
 if(col.gameObject.tag == “Box”)
 {
 relativeXPos = box.transform.position.x + (box.transform.position.x - transform.position.x) ;
 }
 }

Thereafter, to update the circle x position relative to the box x position, all you need to do is apply what you saved in the collision to the current position:

 transform.position = box.transform.position + relativeXPos;

Hope that helps
