I must be doing something wrong somewhere but my UI layout groups don't seem to function as I have seen elsewhere. With this I would expect the buttons to all expand equally to fill the entire panel, this is not the case. The buttons are staying really small and being really spaced out. What I am aiming for is a panel that contains multiple buttons, these buttons should fill the panel in full with varying sizes depending on the size of the button text.
Pixeltoro This seems to have started with Unity Try toggling ALL the toggles child controls size, child force expand and it seems to trigger the resize.

Related Questions.A UI is one of the most important features of software because it is the element of your program that the user will usually be interacting with the most. Without a UI, the software would have to be used with nothing but text and command lines. In a video game, a UI makes it easier for you to interpret data hit points, currency, itemsinteract with a visual world, or alter video and sound settings, for example.
The goal is to create a window that the user can scroll up and down, which contains a grid layout of a basic image. It acts as a sort of UI panel that you can store UI elements on and scroll through them using a mouse or touch input. Think of how a website works. You can scroll up or down and reveal more information by doing so. A Scroll View component in Unity is similar.
Unity has a component called a Grid Layout Group that handles grid arrangement of UI elements for you. This is particularly useful for many kinds of games. Many inventory systems will make use of grid patterns of boxes, which contain item icons and information. Many mobile games will organize all sorts of UI elements into grid patterns, which help make it easy for users to find and press the item they need quickly and without confusion.
This video tutorial also explains the scroll window and grid layout to help you understand these two user interface options. First, I am going to assume you have a basic understanding of Unity.
I will not be covering basic concepts, such as creating a project, adding Game Objects, or how to use the Inspector. If you are curious about the details of these options, refer to the Unity Documentation. The content object is where we will be attaching our GridLayoutGroup component.
The Content object is what the scroll view scrolls through. You can modify the size of this Rect by using the Rect tool to change the width and height.
The scroll view works by allowing you to scroll vertically or horizontally in the Content object Rect area, even if that area is larger than the area of the scroll view.
You can delete the Image from the hierarchy window. This is a very basic implementation of the scroll view and Grid Layout Group components. But hopefully, you see how you can use either of these UI elements for your project. I highly recommend playing around with some of the component settings for both components and see what kind of functionality you can achieve. Have fun! Share this Post. Example of a scroll view. Example of a Grid.I have a script I'm adding to objects which also contain Text components.
My script is meant to run a function whenever the Text's layout updates. This works fine for most of my game objects however there are some where the call back never gets called. At first I thought it was something to do with those objects being instantiated from prefabs I originally asked the question about that but have updated it sincehowever I've narrowed it down to the fact that the objects where the call back doesn't work are in a vertical layout group.
I can understand why the vertical layout group might also be using the call back but surely it shouldn't stop me from using it too? Does anyone know how I can get around this? Interestingly if I register the call back and then on the next line of code do something to change the layout set the font size for examplethe call back does get called - it stops getting called later, presumably once the vertical layout group starts up.

Joined: Jul 21, Posts: 3. The Panel has two Buttons as children.Unity 5: UI - 8.1 Understanding horizontal & vertical layouts
Now I want each button to scale up to half the size of the panel, so that they are equally sized and there's no free space left on the panel. But Unity doesn't seem to control the width and height and only changes the position of the buttons. While the buttons are positioned right, they aren't scaled to fill up the empty space.
I tried adding a Layout Element to the buttons and setting the preferred width to half the panel width and the height to the panel height, bu that didn't seem to work either. What am I doing wrong?

Joined: Sep 8, Posts: 1.If you want to override the minimum, preferred, or flexible size of a layout element, you can do that by adding a Layout Element component to the Game Object. The properties are used in the following manner when a layout controller allocates width or height to a layout element:.
The Layout Element component lets you override the values for one or more of the layout properties. Enable the checkbox for a property that you want to override and then specify the value that you want to override with. Minimum and preferred sizes are defined in regular units, while the flexible sizes are defined in relative units. If any layout element has a flexible size greater than zero, it means that all the available space will be filled out.
The relative flexible size values of the siblings determine how big a proportion of the available space each sibling fills out.
Most commonly, flexible width and height is set to just 0 or 1. Specifying both a preferred size and a flexible size can make sense in certain cases. Flexible sizes are only allocated after all preferred sizes have been fully allocated. Thus, a layout element which has a flexible size specified but no preferred size will keep its minimum size until other layout elements have grown to their full preferred size, and only then begin to grow based on the additional available space.
By specifying a flexible size, this can be avoided and the element can grow to its preferred size in tandem with the other layout elements that have preferred sizes, and then grow further once all flexible sizes have been allocated.
Apply settings from the below snap. Now create four rows which we can see in our project. Note : Uncheck Width of Child Force Expand option, otherwise it should fill the button in whole layout.
How to Work with Layout Element in Unity: An Introduction
Now add elements to each row [HorizontalContainer]. For that create a button in its child and add LayoutElement component. Note : Value between 0. Now, repeat step 4 for other rows to create the multiple row elements of different sizes. Let me know in comment if you have any questions regarding unity.

Created on : 02 July Maulik Kaloliya.I have UI DropDown combo box, constructed from layout groups, buttons and panels and i want to animate combobox elements that basically are buttons placed in Layout Group hide and show act.
Idea was to change their anchored position by Layout Group padding since i can't change position by rectTransform and during test that means changing padding value in inspectoreverything went find, but when i tried to change padding value via script, although value HAS changed in inspector, RectTransform didn't changed.
Any change on inspector, and recTransform update to value passed by script. I did some tests with simple script:. Yes, i did! I have aborded trying to change padding via script. The same effect i have achieved by changing RectTransform. Oh, nice then. Polak The reason is similar as to why you can't directly modify the Vector3 of a transform.
Doing so would update the state of the contained object Vector3 for position The container only keeps a reference of the object, not it's state. So when you did this, sterringLayout. MarkLayoutForRebuild rectTransform ; which it calls internally. Simply grabbing the object updating it and passing it back in won't work either unlike it does with Vector3 on transform. Equals to compare the old value versus the new value. Equals will return true. Both options work but its reccomended to do the first option so that the LayoutGroup class manages the updating as its meant to do.
The second option looks cleaner but if the Unity dev's happen to change LayoutRebuilder then you'd have to come back and update your code too. This makes all sense! I had this problem like an hour ago and I predicted it was something related with that. Fixed here! Thanks a lot.
