![]() You will also need to have a reference to at least the game object that holds your canvas component (if not, a child of that object), as you will need to parent the button to the canvas when you instantiate it. Note that we reference the actual button object as a GameObject, as you will need to include other components to provide realistic functionality. First and foremost, we are using UI.Button, so ensure you include using UnityEngine.UI or otherwise refer to the button object as UI.Button. When setting the parent of the instantiated UI element, it’s recommended to do it using the Transform.SetParent method with the worldPositionStays parameter set to false.įollowing the simple route, we are using some basic Unity methods to instantiate and set up the button. Prefabs of UI elements are instantiated as normal using the Instantiate method. Unity Manual: Creating UI elements from scripting Step Two: Instantiate an instance of your prefab ![]() Does it use an image, text, or both? Maybe even multiple images? What is the text font, color, font size, and alignment? What sprite or sprites should the image use? The reason is that there are an infinite number of way e.g. You might wonder why we don’t have a API methods to create the various types of controls, including visuals and everything. The manual further explains the logic behind this: Ultimately, you have to do this because there are no public constructors for UI elements. Save it as a prefab, so we can reference it via code. Set it up to look exactly how you want it to, and ensure it has all the components you intend to use. Unity Manual: Creating UI elements from scripting Set up the UI element the way you want it to look in the Scene, and then drag the element into the Project View to make it into a prefab. In order to be able to easily instantiate UI elements dynamically, the first step is to create a prefab for the type of UI element that you want to be able to instantiate. ![]() ![]() Once you understand how create a single button, it should not be complicated to create a list of buttons. Creating a button in Unity is quite simple, via scripting. ![]()
