* `attached_node`: if the node under it is not a walkable block the node will be
|
||||
dropped as an item. If the node is wallmounted the wallmounted direction is
|
||||
checked.
|

* `bouncy`: value is bounce speed in percent
|
||||
* `bouncy`: value is bounce speed in percent.
|
||||
If positive, jump/sneak on floor impact will increase/decrease bounce height.
|
||||
Negative value is the same bounciness, but non-controllable.
|
||||
* `connect_to_raillike`: makes nodes of raillike drawtype with same group value
|
||||
connect to each other
|
||||
* `dig_immediate`: Player can always pick up node without reducing tool wear
