Hello, I'm trying to create good UI for Unity but don't know how to make good code for the UI or how to get it to launch the game properly. Any tips?
Youtube tutorials... Lots of youtube tutorials. It sounds like you're starting from zero so that's great. I recommend working through about half a dozen different UI tutorials, and if you're sharp and pay attention, you can probably learn what you need in far fewer. The concepts are incredibly simple and the Unity UI layout stuff is incredibly powerful, but you have to start with the basics.
