# flowlib
Simple flow functions.

## flowlib.is_touching(realpos, nodepos, radius)
Return true if a sphere of `radius` at `realpos` collide with node at `nodepos`.
* realpos: position
* nodepos: position
* radius: number

## flowlib.is_water(pos)
Return true if node at `pos` is water, false otherwise.
* pos: position

## flowlib.node_is_water(node)
Return true if `node` is water, false otherwise.
* node: node

## flowlib.is_lava(pos)
Return true if node at `pos` is lava, false otherwise.
* pos: position

## flowlib.node_is_lava(node)
Return true if `node` is lava, false otherwise.
* node: node

## flowlib.is_liquid(pos)
Return true if node at `pos` is liquid, false otherwise.
* pos: position

## flowlib.node_is_liquid(node)
Return true if `node` is liquid, false otherwise.
* node: node

## flowlib.quick_flow(pos, node)
Return direction where the water is flowing (to be use to push mobs, items...).
* pos: position
* node: node

## flowlib.move_centre(pos, realpos, node, radius)
Return the pos of the nearest not water block near from `pos` in a sphere of `radius` at `realpos`.

* pos: position
* realpos: position, position of the entity
* node: node
* radius: number
