Copying and Pasting cs Code

In cs, like in almost any computer programming language, reading data from a file can be tricky. You add extra lines of code to tell the computer what to do. Sometimes you can copy and paste these lines from other peoples’ code.

For example, you can follow the pattern in this listing:

         public void UpdateListItemPositions()
         {
             if (!listContainerRectTransform.rect.size.Equals(listContainerCachedSize))
             {
                 // checking how many children of list are active
                 int activeCount = 0;

                 foreach (var tr in listContainerTransform)
                 {
                     if (((Transform)tr).gameObject.activeInHierarchy)
                     {
                         activeCount++;
                     }
                 }

                 // if anything changed since last check reinitialize anchors list
                 itemsCount = 0;
                 Array.Resize(ref pageAnchorPositions, activeCount);

                 if (activeCount > 0)
                 {
                     pages = Mathf.Max(activeCount - itemsVisibleAtOnce + 1, 1);

                     if (direction == ScrollDirection.Horizontal)
                     {
                         // looking for list spanning range min/max
                         scrollRect.horizontalNormalizedPosition = 0;
                         listContainerMaxPosition = listContainerTransform.localPosition.x;
                         scrollRect.horizontalNormalizedPosition = 1;
                         listContainerMinPosition = listContainerTransform.localPosition.x;

                         listContainerSize = listContainerMaxPosition - listContainerMinPosition;

                         for (var i = 0; i < pages; i++)
                         {
                             pageAnchorPositions[i] = new Vector3(
                                 listContainerMaxPosition - itemSize * i,
                                 listContainerTransform.localPosition.y,
                                 listContainerTransform.localPosition.z
                             );
                         }
                     }
                     else
                     {
                         //Debug.Log ("-------------looking for list spanning range----------------");
                         // looking for list spanning range
                         scrollRect.verticalNormalizedPosition = 1;
                         listContainerMinPosition = listContainerTransform.localPosition.y;
                         scrollRect.verticalNormalizedPosition = 0;
                         listContainerMaxPosition = listContainerTransform.localPosition.y;

                         listContainerSize = listContainerMaxPosition - listContainerMinPosition;

                         for (var i = 0; i < pages; i++)
                         {
                             pageAnchorPositions[i] = new Vector3(
                                 listContainerTransform.localPosition.x,
                                 listContainerMinPosition + itemSize * i,
                                 listContainerTransform.localPosition.z
                             );
                         }
                     }

                     UpdateScrollbar(linkScrolbarSteps);
                     startingPage = Mathf.Min(startingPage, pages);
                     ResetPage();
                 }

                 if (itemsCount != activeCount)
                 {
                     PageChanged(CurrentPage());
                 }

                 itemsCount = activeCount;
                 listContainerCachedSize.Set(listContainerRectTransform.rect.size.x, listContainerRectTransform.rect.size.y);
             }

         }
