In-Depth Information
If you drag a
Unity UI
control from a
Canvas
and parent it to any other
object in the scene that is not a child of a
Canvas
object, it simply is not
drawn and is ignored. This includes if you drag it to the top of the Unity
project hierarchy.
Unity will also add an
EventSystem
to the scene, if one does not exist
already; this is explained in detail in the following
Event System
section.
To try it out, open a new scene in your project and either:
• Create a new
Canvas
by selecting to the
Create
|
UI
|
Canvas
option in the
hierarchy window, or
• Create any
UI
component by selecting to
Create
|
UI
|
Go Wild
(select any
control) option in the hierarchy window
If you then select the
Canvas
in the project hierarchy, you will see the following in
the
Inspector
window with the default
Screen Space - Overlay Render Mode
:
The default Canvas, with Screen Space - Overlay selected
