@ -9,13 +9,46 @@ Accept folowing params:
* string: name of the node to place
* function(pos): will returns name of the node to place with pos being the placement position
* source_take: table of liquid source node names to take
* itemname: itemstring of the new bucket item (or nil if liquid is not takeable)
* bucketname: itemstring of the new bucket item
* inventory_image: texture of the new bucket item (ignored if itemname == nil)
* name: user-visible bucket description
* longdesc: long explanatory description (for help)
* usagehelp: short usage explanation (for help)
* tt_help: very short tooltip help
* extra_check(pos, placer): (optional) function(pos) which can returns false to avoid placing the liquid. Placer is object/player who is placing the liquid, can be nil.
* extra_check(pos, placer): (optional) function(pos)
* groups: optional list of item groups
This function can be called from any mod (which depends on this one)
**Usage exemple:**
```lua
mcl_buckets.register_liquid({
bucketname = "dummy:bucket_dummy",
--source_place = "dummy:dummy_source",
source_place = function(pos)
if condition then
return "dummy:dummy_source"

usagehelp = S("Place it to empty the bucket and create a dummy liquid source."),
tt_help = S("Places a dummy liquid source"),
extra_check = function(pos, placer)
--pos = pos where the liquid should be placed
--placer people who tried to place the bucket (can be nil)
--no liquid node will be placed
--the bucket will not be emptied
--return false, false
--liquid node will be placed
--the bucket will be emptied
return true, true
end,
