Example: At the beginning of the game the menu will only have the Level 1 button, once the guy passes the level how to create an automatic button for level 2 in this menu? This button will redirect you to level 2, once it passes level 2, a button will appear in the menu with Level3 and so on.
Hello, welcome to Stack Overflow! As a user (even if not so old) I tell you sincerely that your questions tend to be like 0/0 - with no definite answer :P. I notice that you have to question a continuous project (a game, in this case). If you are new to the field of Unity, I recommend that you read a tutorial on the internet because this type of question tends not to proceed on the site. Sincere apologies.
