When I move from Scene mode to Game mode I cannot move my paddle anymore as Rick is doing.
Hi Tero,
You don’t say how you are trying to move it, but I’m assuming you mean with the Translate tool on the menu bar at the top of Unity, if so, this is normal. The Game view is a representation of how you game will look and run - you won’t have the Unity tools in your published game.
In some videos you may see Rick has the Scene and Game view windows side-by-side, this would allow him to move the paddle, or any other GameObject, in the Scene view using the Translate tool, and visualise it moving in the Game view as well.
Hope this helps
