Call the next script or make your book/scroll as an item and put the code in the note field of that item. Use the following;For the variables "book" and "scroll", you'll have to set the
name of the book/scroll ('picturename'). For the variable "back", you can setthe name of the back images of a book. If you leave it for what is, it'll use the default settings from the script-setup ("BACK_PIC"). For the "draw_style", you can change the way of how you've set up the pictures. This variable is optional. You do have to set "back" if you want to use this. If you leave it empty, it'll use the default you've set in the script-setup ("DRAW_STYLE"). For the variable "from_item", you can set if you want to return to the item window when you close the book/scroll. But if you leave it for what it is, it'll see for itself if the code came from an item or not (recommented).

Use correct filenames for your book! First of all check the script-setup and make it to how you want it before making your pictures. Look at the "BOOK_MAP", this is the place where you're going to put your pictures. Now you can make the pictures... Though be aware! You need a to make a background for your pages to show on. Size it (max) 544*416 and name it whatever you want. Go to the scriptsetup and put the name of that background after "BACK_PIC". Next you are going to make the pages with your text and/or pictures and all, that's all up to you since they are
pictures, so everything is possible. Just go and start making your pages with any size you like (change the "DRAW_STYLE" in the script-setup to your style). Every page should have it's own picture! When you're done with a page, and you're going to save and name it, set the name like this; 'bookname-pagenumber'. So if you just created the 2nd page of your book called 'ghost', the name of the picture must be 'ghost-1'. Make sure you see that the second page of the book, has the number 1. So the first page has the number 0.
For the scrolls, first check in wich map the pictures need to come. After that, just go and make some nifty looking pictures that will be shown and can be scrolled by the user in all 4
directions.
PS: RPGMakerVX only supports png/jpg/jpeg picture-files.

The last 3 settings of the setup; CENTER_OFFSET, NEXT_PAGE and PREV_PAGE, are explaind below.
{CENTER_OFFSET}
The center_offset setting defermens the y-offset of the pages from the middle. So if you want your pages not to be drawn at the very middle of the back-picture, you'll have to set the center_offset to any given number you want the pages to be offset from the middle. For example if you have page-pictures that are sized 270*412, and you want them to be shown, not directly on the center of your background, but in the center of each half, you want to set the center_offset to 2 since this will center them out on every half.
{NEXT_PAGE}
This setting determens wich key needs to be pressed to move the pages to the next. You can only use known inputs by the game. Though, you can extend this by useing various other scripts that will allow you to use all inputs from your whole keyboard.
{PREV_PAGE}
This is actualy the same as the next_page setting, only this will bring the reader to the previous page.
For the scrolling part of the setup, the 4 SCROLL_directions and SCROLL_SPEED remains.
{SCROLL_UP/DOWN/RIGHT/LEFT}
For the directions, just changes the input to what you prefer, though the default are the most usefull (in my opinion).
{SCROLL_SPEED}
The scrollspeed, is the amount of pixels the scroll moves when the player presses one of the directionbutons once.
