Natural slopes library

  • Version 1.5
  • With thanks to all modders, mainly from the stairs mod for study.

This mod add the ability for nodes to turn into slopes and back to full block shape by themselves according to the surroundings and the material hardness. It creates more natural looking landscapes and smoothes movements by removing some edges.

Slopes can be generated in various ways. Those events can be turned on or off in settings. The shape is updated on generation, with time, by stepping on edges or when digging and placing nodes.

As Minetest main unit is the block, having half-sized blocks can break a lot of things. Thus half-blocks like slopes are still considered as a single block. A single slope can turn back to a full node and vice-versa and half-blocks are not considered buildable upon (they will transform back into full block).


None, this is a standalone library for other mods to build upon. It doesn't have any effect by itself.

Optional dependencies:

  • poschangelib: to enable shape update when walking on nodes
  • twmlib: to enable update from time to time
