So, I have this huge island with castles, mining sites, and forests.
The player spawns on the island, but currently it has no boundaries. I want to create a giant, perfectly circular ice wall that encloses the island. Later on, I might add a lift that takes the player to the top of the wall, but for now, the player should be stuck inside the island.
I don’t have much experience with game development, and I just started, so excuse me if this question seems simple or stupid.
How do I create this giant ice wall? I also want to add special details to parts of the wall, like swords, a ship, books, chests, Viking casks, medieval armor, or maybe even animals stuck inside the ice. For reference, I want it to look similar to the Wall from Game of Thrones, but with some transparent ice sections where you can see objects inside the wall — without being able to see through to the other side.
So, how can I do that?
