Note: Rect represents an abstract rectangle, and can be used in a variety of situations.

As such, Rects don't have an explicit top, bottom, left or right. For example, Y values in Camera space are measured from the bottom of the screen, but Y values in Editor GUI space are measured from the top of the window, therefore whether the Y value of a Rect is its "top" or "bottom" will vary depending on where you use the Rect value. You can refer to the corners by using Rect.

Publication Date: A Scroll Rect can be used when content that takes up a lot of space needs to be displayed in a small area. The Scroll Rect provides functionality to scroll over this content. It can also additionally be combined with one or two Scrollbars that can be dragged to scroll horizontally or vertically.

The important elements in a scroll view are the viewportthe scrolling contentand optionally one or two scrollbars. This image shows a setup where the viewport is a child to the scroll view root. To scroll content, the input must be received from inside the bounds of the ScrollRect, not on the content itself. Take care when using Unrestricted scrolling movement as it is possible to lose control of the content in an irretrievable way. When using Elastic or Constrained movement it is best to position the content so that it starts within the bounds of the ScrollRect, or undesirable behaviour may occur as the RectTransform tries to bring the content back within its bounds.

These are typically placed in the hierarchy as siblings to the viewport, and when present, should be dragged into the Horizontal Scrollbar and Vertical Scrollbar properties of the Scroll Rect, respectively. Note that the auto-hiding only ever happens in Play Mode. In Edit Mode the scrollbars are always shown.

This prevents marking the scene A Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. If one or both scrollbars have their visibility behaviour set to Auto Hide And Expand Viewthe viewport is automatically expanded when the scrollbars are hidden in order to take up the extra room where the scrollbars would otherwise have been.

With this setup, the position and size of the view is driven by the Scroll Rect, and the width of the horizontal scrollbar as well as the height of the vertical scrollbar is driven as well. With this setup the viewport as well as the scrollbars must be children to the Scroll Rect root GameObject. Did you find this page useful? Please give it a rating:.

Following the tutorial available on Unity website, it show how to scroll an image which is greater in size than the scroll rect, but how to get this setup working for stuffs that might be added to the panel later in game or runtime, which will increase in height or width but still the scroll will reflect to the old height or width, rather than the new dimensions. This link solved my problem, I'm sure it helps you too. Find the attached demo. You can add objects under "Grid-Dynamic" gameobject dynamically and scrolling works fine.

I sent you some rep. This comment seriously made my day. I've been fighting with the ScrollRect forever and never had a good solution. Thanks SniperEvanIt is great that demo is being helpful to you.

Well that's what I get for not checking my own menu item. BoredMormon is right you have to set the RectTransform to dynamically increase in size with enough for each item that you include. Not written the code to fix mine yet but if you're struggling I'll post the solution when I have it.

Rect Constructor

You actually want to constrain it on the vertical. Also add layout elements to each button. Check out my UI tutorials for a video. It's not exactly what you are after, but you should be able to figure out all the pieces. I added the demo unity package to it under CursedIsle username to show how to build menu items from a list. As I say on the YouTube comments virus check and open in a new project so I don't break anything you've done.

I spent a lot of time to solve this issue. I tried every proposed solution on the web. None of them gave me the result i needed. I ended up calculating the height via a Script MonoBehavior. My aim was to calculate a 2D RectTransform ScrollContent that has children populated dynamically using the start so the script executes once on update after all has been initialized. You're example won't work properly without the addition of a VerticalLayoutGroup to the Content object.

Content Size Fitter is doing what u are asking. It's taking the preferred size from Text component and increasing size every time there is a new line in Text. My example is tested and works great. Oh I see what you've done, you've added a text component directly to the content gameobject, in which case it will work as you stated.

I prefer adding text objects as children of the content gameobject, as this gives the flexibility of being able to add multiple text objects or even other UI elements. In which case the verticallayoutgroup is required as I described.

The following examples are illustrated in GUI space, where 0,0 represents the top-left corner and Y increases downwards. Rectangles can be specified in two different ways. The first is with an x and y position and a width and height : The other way is with the X and Y coordinates of each of its edges.

These are called xMinxMaxyMin and yMax : Note that although x and y have the same values as xMin and yMinthey behave differently when you set them. Setting x or y changes the position of the rectangle, but preserves its size: Setting any of xMinxMaxyMin and yMax will resize the rectangle, but preserve the position of the opposite edge: See Also: GUI Scripting GuideCamera.
