Clean up skin listing (#100)
Supersedes the 'fsep' setting by automatically detecting the texture name in both, the skin list and the updater scripts. New, automatically fetched skins will now always use the '.' delimiter to avoid player name issues. In case of ambiguous texture names, a warning is logged.

In this folder the skin files could be placed according the following file naming convention.
|
||||
This location is where you can put your custom skins.
|
||||
|
||||
skinsdb uses an underscore as default seperator for filename splitting which can cause problems with playernames containing "_",
|
||||
see https://github.com/minetest-mods/skinsdb/issues/54.
|
||||
The config setting skinsdb_fsep (texture filename seperator) was added as a workaround which also offers "."(dot) as seperator,
|
||||
dot is the only character which is allowed in textures but not in playernames.
|
||||
To keep compatibility with older versions underscore is the default value.
|
||||
|
||||
fresh install:
|
||||
you should change the seperator to "." to avoid that problem.
|
||||
existing install:
|
||||
- change the filenames according to the naming convention with dot as seperator instead of underscore
|
||||
- change the texture filename seperator in settings or add "skinsdb_fsep = ." to your minetest.conf before starting your server
|
||||
List of accepted texture names
|
||||
------------------------------
|
||||
|
||||
Public skin available for all users:
|
||||
character_[number-or-name].png
|
||||
character.[number or name].png
|
||||
|
||||
One or multiple private skins for player "nick":
|
||||
player_[nick].png or
|
||||
player_[nick]_[number-or-name].png
|
||||
One or multiple private skins for player "[nick]":
|
||||
player.[nick].png
|
||||
player.[nick].[number or name].png
|
||||
|
||||
Preview files for public and private skins.
|
||||
Optional, overrides the generated preview
|
||||
character_*_preview.png or
|
||||
player_*_*_preview.png
|
||||
Skin previews for public and private skins:
|
||||
character.[number or name].preview.png
|
||||
player.[nick].preview.png
|
||||
player.[nick].[number or name].preview.png
|
||||
|
||||
Note: This is optional and overrides automatically generated preciewws.
|
||||
|
||||
|
||||
Legacy texture names
|
||||
--------------------
|
||||
|
||||
The character `_` is accepted in player names, thus it is not recommended to
|
||||
use such file names. For compatibility reasons, they are still recognized.
|
||||
|
||||
character_[number or name].png
|
||||
player_[nick]_png
|
||||
player_[nick]_[number or name].png
|
