Welcome to this Unity debugging tutorial on the Unity UI layering system. In this video, we will talk about a problem that can occur where you are not able to select or click on certain UI objects. This lesson will teach you about using the Unity UI system, UI buttons, and UI images.
How to Fix UI Layers
This problem where you cannot click on Unity UI object can occur because of Unity’s UI layering system. If one UI object is over top of another UI object you will not be able to click through the UI object on top to select the one behind unless you have disabled Raycast Target on the image component. This can also occur with not being able to click on UI objects that are part of a world space canvas when you have a screen space canvas as well. We will teach you how to fix your problems in Unity and to you how to use Unity’s UI system better.
