🌊 Explore the Ocean
Simple Submarines is designed to make ocean exploration more useful and immersive.
You can travel underwater, enter the submarine's interior and use it as a small mobile base while exploring distant oceans.
🎮 Controls
While piloting the submarine:
W — Move forward
S — Reverse
A — Turn left
D — Turn right
Space — Rise
Ctrl — Dive
G — Enter the cabin
Shift — Dismount
The dive and cabin keys can be configured from Minecraft's controls menu.
🏠 Habitable Interior
The submarine contains a separate interior cabin with useful survival equipment.
Inside you can find space for:
- Beds
- Chests
- Crafting tables
- Furnaces
- Lighting
- Pilot controls
The cabin is persistent, meaning your interior and stored belongings remain saved.
🚪 Cabin System
Use G to enter the submarine cabin.
Inside the cabin:
- The blue hatch is used to leave the submarine.
- The green pilot console lets you control the submarine.
- Shift + interact with the blue hatch can be used as an emergency exit if necessary.
If the normal exterior exit is obstructed, the submarine will warn you instead of placing you inside solid blocks.
🛡️ Safety Systems
Simple Submarines includes several systems designed to reduce common vehicle problems:
- Placement checks to prevent spawning the submarine inside solid blocks
- Protection against duplicate submarine placement
- Occupancy checks before picking up the submarine
- Blocked-exit detection
- Emergency exit system
- Persistent cabin data
🛠️ Crafting Recipe
The submarine can be crafted using:
