Features:
|
|
- Items are destroyed by lava
|
|
- Items are pushed along by flowing water (thanks to QwertyMine3 and Gustavo6046)
|
|
- Items are removed after 900 seconds or the time that is specified by
|
|
remove_items in minetest.conf (-1 disables it)
|
|
- Particle effects added
|
|
- Dropped items slide on nodes with {slippery} groups
|
|
- Items stuck inside solid nodes move to nearest empty space
|
|
- Added 'dropped_step(self, pos, dtime, moveresult)' custom on_step for dropped items
|
|
'self.node_inside' contains node table that item is inside
|
|
'self.def_inside' contains node definition for above
|
|
'self.node_under' contains node table that is below item
|
|
'self.def_under' contains node definition for above
|
|
'self.age' holds age of dropped item in seconds
|
|
'self.itemstring' contains itemstring e.g. "default:dirt", "default:ice 20"
|
|
'self.is_moving' true if dropped item is moving
|
|
'pos' holds position of dropped item
|
|
'dtime' used for timers
|
|
'moveresult' table containing collision info
|
|
|
|
return false to skip further checks by builtin_item
