Link React Trans forms

README.MD

Attach it to GameObject.

Assign the two RectTransforms that you want to link to the rectTransform1 and rectTransform2 variables in the inspector.

The Update method of the script will be called every frame, and it will update the position of rectTransform2 based on the current position of the right edge of rectTransform1.

LinkRectTransforms.cs

using UnityEngine;

public class LinkRectTransforms : MonoBehaviour
{
    public RectTransform rectTransform1;
    public RectTransform rectTransform2;

    private void Update()
    {
        // Get the current position of the right edge of RectTransform1
        float rightEdge = rectTransform1.position.x + rectTransform1.rect.xMax;

        // Set the position of the left edge of RectTransform2 based on the right edge of RectTransform1
        rectTransform2.position = new Vector3(rightEdge - rectTransform2.rect.xMin, rectTransform2.position.y, rectTransform2.position.z);
    }
}
