So I need to make a menu for my future iOS game(everything will be touch based), now I've checked the FAQ and google and youtube, but everything I've managed to find are just examples for simple menus, like the 1945 one, and those don't really help me...
Here is what I wanna do if you can please help:
First button will be a "Start Game", if you click it a new screen appears with 4 levels, but only the first level is selectable, the other 3 are greyed out and will unlock in order(after you finish level 1 the second level is selectable, after you finish 2 you can play 3 and so on).
I have a vague idea on how to achieve this(using variable, ex. "if level1 completed=true" or something like that, right?) but no idea where to start or what steps to follow.
How do I make the buttons "untouchable" untill the var=true, how many layers do I need( one for start game menu, one for levels, one for options, and so on? Cause thats gonna end up beeing 10++ layers just for the menu...)
Second button under "Start Game" will be "Options". When you click this you will be taken to another screen where I want to have 2 sliders one for music level and one for effects level. No idea how do this...
Then 2 more buttons "How to play" and "Quit Game" these 2 should be pretty simple, right?
If there are any tutorials that explain/show how to do this and I've missed them I apologize, please link. Otherwise if you can please explain what I have to do in as much detail as possible as this is my first game and I am very much a newb.
Thank you very much for your time&help, sorry for writing so much.
