item_entity.lua replacement
edited by TenPlus1
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
-
Can use new on_pickup() function if available
-
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

dropped_step() examples:
-- if gunpowder dropped on burning tnt or gunpowder then remove
if minetest.registered_items["tnt:gunpowder"] then
minetest.override_item("tnt:gunpowder", {

if (self.node_inside
and self.node_inside.name == "tnt:gunpowder_burning")
or (self.node_under
and self.node_under.name == "tnt:tnt_burning") then
minetest.sound_play("builtin_item_lava", {
pos = pos,
max_hear_distance = 6,
gain = 0.5
})
self.itemstring = ""
self.object:remove()
return false -- return with no further action
end
end
})
end
-- if 2x mese crystal and 2x crystal spike dropped in pool of water_source -- then merge into a single crystal_ingot.
if minetest.registered_items["ethereal:crystal_spike"] then
minetest.override_item("ethereal:crystal_spike", {
dropped_step = function(self, pos, dtime)
self.ctimer = (self.ctimer or 0) + dtime
if self.ctimer < 5.0 then return end
self.ctimer = 0
if self.node_inside
and self.node_inside.name ~= "default:water_source" then
return
end
local objs = core.get_objects_inside_radius(pos, 0.8)
if not objs or #objs ~= 2 then return end
local crystal, mese, ent = nil, nil, nil
for k, obj in pairs(objs) do
