Since the last update I’ve been mostly working on changing how the game handles moving the submarine which is why there hasn’t been much to show. In the current version the levels actually move around the submarine while the sub itself is stationary, which makes it really difficult to have multiple submarines in the same level, or any structures outside the sub for that matter. Even though a game mode with multiple subs isn’t on my to-do list at the moment (maybe at some point in the future though), some sort of explorable underwater structures (sunken subs, alien ruins…?) are a must, so I needed another way of moving the submarine.
How it works now is that neither the submarine or the level actually move: instead there’s an invisible submarine-shaped physics object moving around the level and the insides of the ship are just rendered wherever that object is.
Here are a couple of screenshots of some other additions:
