# wielded_light mod for Minetest
|
||||
|
||||
Idea taken from torches_wieldlight in https://github.com/minetest-mods/torches, but written from scratch and usable for all shining items.
|
||||
|
||||
|
||||
|
||||
All bright nodes with light value > 2 lighten the player environment if wielded, with value fewer by 2. (Torch 13->11 for example)
|
||||
|
||||
Dependencies: none
|
||||
|
||||
License: [GPL-3](https://github.com/bell07/minetest-wielded_light/blob/master/LICENSE)
|
||||
|
||||
|
||||
Shining API:
|
||||
|
||||
`function wielded_light.update_light(pos, light_level)`
|
||||
Enable or update the shining at pos with light_level for 0.6 seconds. Can be used in any on_step call to get other entitys shining for example
|
||||
|
||||
|
||||
`wielded_light.register_item_light(itemname, light_level)`
|
||||
Override or set custom light level to an item. This does not change the item/node definition, just the lighting in this mod.
|
||||
|
||||
`function wielded_light.update_light_by_item(stack, pos)`
|
||||
Update light at pos using item shining settings -from registered item_light or from item definition

## Walking Light
|
||||
|
||||
### Description:
|
||||
|
||||
A mod for [Minetest](http://minetest.net/) that illuminates the area around a player when wielding a light-emitting item. Also supports equipped armor with [3d_armor](https://content.minetest.net/packages/stu/3d_armor/).
|
||||
|
||||
|
||||
|
||||
#### History:
|
||||
|
||||
- forked from [v0.6][forum.echo] of Echo's *walking_light*
|
||||
- forked from [Git commit 766ef0f](https://github.com/petermaloney/walking_light/tree/766ef0f) of petermaloney's *walking_light*
|
||||

||||

||||
- Code: [MIT](LICENSE.txt)
|
||||
- Textures: [CC0](https://creativecommons.org/publicdomain/zero/1.0/legalcode)
|
||||
|
||||
### Requirements:
|
||||
|
||||
```
|
||||
- Minetest minimum version: 5.0.0
|
||||
- Depends: none
|
||||
- Optional depends: default (for torch & megatorch)
|
||||
- Privileges: server (for using chat commands)
|
||||
```
|
||||
|
||||
### Usage:
|
||||
|
||||
Main methods:
|
||||
|
||||
```
|
||||
wlight.register_item(iname, radius)
|
||||
- Registers an item to emit light when wielded.
|
||||
- `iname`: Item technical name.
|
||||
- `radius`: Distance light will reach (max: 10).
|
||||
|
||||
wlight.register_armor(iname, radius, litem)
|
||||
- Registers an item to emit light when equipped in armor inventory.
|
||||
- `iname`: Item technical name.
|
||||
- `radius`: Distance light will reach (max: 10).
|
||||
- `litem`: Whether or not this item should also be registered with `wlight.register_item` (default: true).
|
||||
```
|
||||
|
||||
Settings:
|
||||
|
||||
```
|
||||
wlight.enable_megatorch
|
||||
- Enables wlight:megatorch item.
|
||||
- default: true
|
||||
```

----
|
||||
- forked from petermaloney @ Git commit 766ef0f ( https://github.com/petermaloney/walking_light/tree/766ef0f )
|
||||
- changed code license to MIT
|
||||
- added mod.conf
|
||||
- re-created underlay image
|
||||
- some code cleanup & optimization
|
||||
- hand is not checked for light
|
||||
- added global method for registering an armor item
|
||||
- segregated code into modules
|
||||
- removed walking_light:pick_mese & walking_light:helmet_diamond (mods should register their own light items)
|
||||
- megatorch can be disabled via setting
|
||||
- added localization support
|
||||
- added option to set custom light radius when registering item or armor
|
||||
- removed method "walking_light.register_tool"
|
||||
- renamed to "wlight"
|
||||
- consolidated chat commands into single "wlight" command
|
||||
- fixed "/wlight add" command not able to illuminate more than one node

|
||||
------------
|
||||
- forked from walking_light v0.6 by Echo ( https://forum.minetest.net/viewtopic.php?t=2621 )
|
||||
- bug fixes & code optimizations
|
||||
- light updated on player login
|
||||
- added 3d_armor support
|
||||
- added items walking_light:helmet_diamond & walking_light:megatorch
|
||||
- added global method for registering items for use with walking_light
|
||||
- replaced deprecated methods & parameters
|
||||
- prefixed chat commands with "walking_light"
