Unity 2019.4.9f1 - Toggle Show/Hide Gameobject with one keystroke. - Questions & Answers - Unity Discussions

Hi all. I have constructed a spiral freezer and want to simulate automated cleaning on it. To do that I am making 9 “segments”, each consisting of an empty gameobject with several particle systems as children. I would like to start with all segments hidden og then be able show/hide each segment when pressing keys 1-9. By searching the web I found several answers, but all seem to be outdated? Can anyone help me code show/hide a gameobject+children in one keystroke?

Help, when I try to install unity version 2019.4.31 it doesn't
