# Minetest mod metatools
|
|
|
|
Get everything possible* about a node just by clicking it with metatools:stick!
|
|
|
|
## Differences in Poikilos' fork:
|
|
This is a hard fork oriented around getting information without typing any commands.
|
|
- All known* metadata is shown on click! There is no need for various commands to traverse the tree, though the original chat command code is intact.
|
|
- Click a node and get its inventory.
|
|
- Click an entity and list the entire LuaEntitySOA tree!
|
|
- See the "[Minetest API Notes](minetest-api-notes)" section below.
|
|
- The texture is redone so that doesn't any longer have an invasive and inappropriate CC-BY-NC-SA license from the upstream version of metatools.
|
|
|
|
`*` All metadata where how to obtain it is known by the maintainer of this repo (except where there is an open issue).
|
|
|
|
|
|
## Authors
|
|
Code:
|
|
- 2015-2016 LeMagnesium/Mg/ElectronLibre and Paly2/Palige (mod inspired by mgl512's itemframe issue)
|
|
- 2017-2022 Poikilos (Poikilos' fork of Version 1.2.2)
|
|
|
|
Textures:
|
|
- 2022 Poikilos (redone "metatools_stick.png" *replaces one with invasive and inappropriate CC-BY-NC-SA license [old texture was by Ataron]*)
|
|
|
|
|
|
## Purpose
|
|
This mod's aim is to provide a way for admins to navigate through any (ok, not
|
|
ignores) nodes on the map, and see values of its metadatas at any of their
|
|
stratum.
|
|
|
|
|
|
## Install
|
|
- Copy the repo folder containing init.lua to your Minetest mods folder (The resulting folder should be mods/metatools/).
|
|
- Enable the mod for the world.
|
|
- You can remove the "projects" folder to lighten the "game" if necessary (Keeping the png is useful but only for documentation--Nothing in "projects" is used by the mod code).
|
|
|
|
|
|
## Special thanks
|
|
- mgl512 (Le_Docteur) for its locked itemframe which gave me the idea of a tool
|
|
allowing to see/edit metadatas
|
|
- Ataron who created the stick's texture
|
|
- palige who agreed to test the mod for its first release, and contributed to the last version
|
|
|
|
|
|
## Use
|
|
- After following the "Install" steps above, open the world in Minetest.
|
|
- Type `/grantme all`
|
|
- Type `/giveme metatools:stick`
|
|
|
|
The chat commands from https://github.com/Lymkwi/minetest-mod-metatools are still present but usually not necessary:
|
|
- Type `/meta help` to see instructions on chat commands.

### Minetest API Notes
|
|
|
|
#### Entity Metadata
|
|
The magic sauce to get the entire LuaEntitySOA of a pointed_thing was finally discovered by accident (when researching unrelated API feature(s)) after no one would/could answer my question:
|
|
```Lua
|
|
local pointedObjRef = pointed_thing.ref;
|
|
-- . . . some other code is here, then ...
|
|
local luaEntity = pointedObjRef:get_luaentity();
|
|
```
|
|
|
|
#### Node metadata
|
|
|
