This mod adds the "Aquavator Cart", a minecart-like entity which travels only in water, and only strictly vertically up/down.
For robustness, Cart movement is implemented using successive set_pos() to move into neighboring nodes, and not via the entity velocity mechanics in the game engine. That way, the Cart never moves anywhere it shouldn't, even when big lags occur. Unlike many other elevator implementations, the code also ensures that all map blocks the Cart moves through are loaded before they are read. The Cart automatically pauses its movement into a new mapblock until the mapblock is loaded.
Apart from the robustness aspect, this elevator implementation also explores the idea of using a vertical water column as the "tracks" that the elevator travels through. Since water is already in the game, this makes this elevator very cheap, and makes the mod very simple.
To use the mod: Create a vertical water column, which acts as the "tracks" for the Aquavator Cart. Place the Cart in the water column like a regular minecart. Entering/leaving the Cart also works like a regular minecart. Move up/down by pressing Jump or Sneak, respectively. Stop by pressing any of the sideways movement keys WASD. Picking up the Cart into your inventory is a simple left-click (without Sneak). The player riding the Cart has unlimited air supply.
