I am currently working on my next project but I am trying to keep it at the "prototype" stage as long as possible with placeholder graphics and systems until I have nailed down the gameplay loop. This way if I have to throw something out or remake it I can do so without losing too much work.
I am currently wanting to make some interface and menus for the game, like an interface/menu for buying upgrades and items etc etc in the game.
My question is if there are any good objects or extensions for this purpose? The simple "button" object works alright for buttons but it is of course very limited. I sort of wish you could also display numbers on the button so you could for example make it read "Sword" and then have the price in a number on the button etc.
Is there any such things or other that could make it more convenient to build prototype menus and systems like this?
