Slabs are placed horizontal instead of vertical, even if they are
placed on a wall.
Slabs are rotated automatically if they are placed to another slab,
no matter which material.
Slabs are placed at the lower position if the placer points into
the lower half of the pointed node and to the upper position if
pointed to the upper half.
Stairs are placed normal if the placer points to the lower half of
the pointed node and rotated upside down if pointed to the upper half.
This implements a node-timer based leafdecay mechanism, and exposes
an API to use it in mods.
The API is documented in game_api.txt.
`default.register_leafdecay(leafdecaydef)`
`leafdecaydef` is a table, with following members:
{
trunks = { "default:tree"}, -- nodes considered trunks
leaves = { "default:leaves", "default:apple"}, -- nodes considered leaves
radius = 3, -- activates leafdecay this far from the trunk
}
The algorithm will drop `leaves` items in the area if no `trunks` are found
in the `trunk_radius` sized area around the position of the leaf. If a node
listed in `leaves` has a group `leafdecay_drop > 0`, then the item is dropped,
otherwise the item is removed but not dropped.
The algorithm also implements a value `default.leafdecay_speed` (default
15) which can be modified to increase or decrease of the leaf decay. The
algorithm will vary the actual speed a bit to introduce randomness.
Leaf decay is randomized by 0.1 seconds to reduce the chance that
decay happens many times on the same second interval. This requires
nodetimer_interval to be set to values lower than 1.0 to have an
effect.
The leaves will decay between 2 and 10 seconds after digging the trunk,
and happen at non-integer second intervals.
