5. Set the second element of this array to SelfDestruct . With this, the Info
button will create a new instance of a popup_info panel and destroy it-
self. The pattern we will use to return to the main menu will be such that the
popup_info button allocates a new instance of the pop up when instructed
to do so, after which it will destroy itself. In this way, the content of the UI pop
up for both pages is completely contained inside the pop-up Prefabs we have
created in the editor.
6. Let's create a new script that manages the pop up at its top level; call
it popupPanel . Associate an instance of this script with the root of the
MainMenu .
7. In this script, create a single public string named nametxt and a reference to
TextMesh . In the start method, copy the public string variable's contents
over the top of the string member of the TextMesh . This gives a simpler in-
terface to name the pop up; we will use this script as a central place to inter-
face with the pop up.
