# Minimal API for `doc_identifier`
|
||
|
|
## Introduction
|
||
|
|
The tool can identify blocks and players natively, and also handles falling
|
||
|
|
nodes (`__builtin:falling_node`) and dropped items (`__builtin:item`) on its
|
||
|
|
own.
|
||
|
|
|
||
|
|
However, the identifier can't “identify” (=open the appropriate entry) custom
|
||
|
|
objects because the mod doesn't know which help entry to open (if there is
|
||
|
|
any). One example would be the boat object (`boats:boat`) from the boats mod
|
||
|
|
in Minetest Game.
|
||
|
|
If the player tries to use the tool on an unknown object, an error message is
|
||
|
|
shown.
|
||
|
|
|
||
|
|
Because of this, this mod provides a minimal API for mods to assign a help
|
||
|
|
entry to an object type: `doc_identifier.register_object`.
|
||
|
|
|
||
|
|
## `doc.sub.identifier.register_object(object_name, category_id, entry_id)`
|
||
|
|
Registers the object/entity with the internal name `object_name` to the
|
||
|
|
entry `entry_id` in the category `category_id`.
|
||
|
|
It is in the modder's responsibility to make sure that both the category and
|
||
|
|
entry already exist (use `doc.entry_exists` or depend (optionally or not) on
|
||
|
|
the respective mods) at the time of the function call, otherwise, stability can
|
||
|
|
not be guaranteed.
|
||
|
|
|
||
|
|
Returns `nil`.
|
||
|
|
|
||
|
|
### Example
|
||
|
|
From `doc_minetest_game`:
|
||
|
|
|
||
|
|
if minetest.get_modpath("doc_identifier") ~= nil then
|
||
|
|
doc.sub.identifier.register_object("boats:boat", "craftitems", "boats:boat")
|
||
|
|
end
|
||
|
|
|
||
|
|
This enables the tool to be used on the boat object itself. The conditional is
|
||
|
|
an idiom to check for the existence of this mod.
|
||
|
|
|
||
|
|
## Note on dependencies
|
||
|
|
If you just need `doc.sub.identifier.register_object` using only an **optional**
|
||
|
|
dependency for your mod is probably enough.
