Question by MBehtemam · Aug 19, 2015 at 09:41 PM · transformparentitween

change y position of child when relative to parent and iTween

i have parent/child object in my scene. for moving child i use iTween.MoveTo. but when i change the parent position the child position doesn't change and it play animation in it's start point that animation is played. also when i set transform.position to parent.transform.position or localPosition to Vector3.zero nothing happen and child y position is still in it's first instansate position.

this is my Restart method that call when position of parent is changed :

public void Restart() { if (RandomDirection) { int rnd = Random.Range(0, 2); if (rnd == 0) { direction = Direction.Left; } else if (rnd == 1) { direction = Direction.Right; } } if (RandomSize) { float width = Random.Range(0.5f, 1.5f); Vector3 localScale = transform.localScale; localScale.x = width; transform.localScale = localScale; } if (RandomSpeed) { Speed = Random.Range(5f, 10f); } else { Speed = 1f; }

     float move = 0f;
     Vector3 pos = transform.position;
     if (UseParentYPosition)
     {
         Transform parent  = GetComponentInParent<Transform>();
         pos = parent.position;
     }
     else{
         pos = transform.position;
     }
     if (direction == Direction.Left)
     {
         pos.x = leftStartPosition;
         move = rightStartPosition;
     }
     else if (direction == Direction.Right)
     {
         pos.x = rightStartPosition;
         move = leftStartPosition;
     }
     transform.position = pos;
     iTween.MoveTo(this.gameObject, iTween.Hash("x", move, "easetype", iTween.EaseType.linear, "looptype", iTween.LoopType.loop, "speed", Speed));
 }

so my question is how to change y postion of child to parent y position when the position of parent is changed.
