You can Enable or Disable a Canvas by clicking on the toggle button located in the top right-hand corner.
When the Canvas is enabled, the programming in it will be activated in Play mode.
When the Canvas is disabled, the programming in it will not be activated in Play mode.
You can also decide in a Canvas to Enable or Disable another Canvas during the Experience with the "Canvas State" in Action Nodes.
For example, if I want a Canvas (Canvas2) to Enable after 5 seconds in the Experience, I have to disable the Canvas first. Then I have to put in my main Canvas (here, Canvas1) the Node "Canvas State". In this Canvas, you have to write the name of the Canvas you want to activate (here, Canvas2) and click True.
So you can program in advance that a Canvas will be Enabled or Disabled by writing the name and clicking on True or False.
