Hey guys,
I am doing a 2D-Sidescroller right now and I have a main menu and all that stuff, but I want to have a “How To Play” - Page and/or a wiki page INSIDE the game, where you have something like a book and under it 2 arrows to go to the next page and so…I want to explain the controls and the enemys, lore like towns and races to the player.
Thanks for help 
The control you are looking for is usually called “tab navigator”, or “view navigator”.
You could accomplish it with a row of buttons, and depending of the clicked button you should show one of panels with content.
Alternatively, buttons could be dropped out in favor of 2 arrows changing the active panel.
If you’re not into GUI programming, you might use one of the pre-made GUI systems found in the Asset Store.
Thank’s for your tips I’ll defenetly check out the premade Assets
