As we have see scripts can be run from inside the editor, we are going to add editor specific commands such as add/scatter 50 items( thanks Element ) to the scene. But the main scripts can only be run from the "play mode" ( press the blue play button) . The editor shows the in game visuals as they will be seen, but to see the game screens, run the game scripts you need to press the play button.
UCM@ I think this answers your question
