Create:Backtank Expansion

This mod extends the functionality of Create’s backtanks and optionally Create’s jetpacks. It allows players to carry multiple backtanks in their inventory, and the equipped jetpack or backtank will draw from a shared air pool created from all backtanks the player is carrying. This provides significantly longer exploration time, both underwater and in flight.

The system works seamlessly with the Potato Cannon and Extendo Grip, ensuring full compatibility with Create’s existing mechanics. Equipped backtanks and jetpacks automatically refill using the spare backtanks in the player’s inventory, removing the need for manual air management.

Pressing J enables the time‑remaining display, using the same visual format as Create’s built‑in backtank and jetpack air indicators.
