Hello, can I use easier and without any single line of code a complete game without programming in lumberyard?
Yes if you are talking about Script Canvas which is visual scripting everything is nodes that you connect to make the code. To make a game with no programming at all is fully impossible because something needs to run the game and what you do in it. So no to your question, but yes to the normal question which is without typing it all out.
How can i enable and use Script Canvas?
it is already in the engine by default I believe, if not it is a gem you add to your project in the configurator.
