# Node Extensions
Provides helpers and backend functionality for nodes.

## Scope
- how entities interact with nodes
- how nodes interact with other nodes (grass spreading etc)
- how nodes change over time

## API
Currently implemented features:
```lua
core.register_node(name, {
	-- when a player or other object is near a node
	_on_nearby = function(pos, object, dtime) end,
})
```
