Areas mod for Minetest 0.4.8+
=============================
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Configuration
-------------
If you wish to specify configuration options, such as whether players are
allowed to protect their own areas with /protect (Disabled by default), you
should check config.lua and set the appropriate settings in your minetest.conf.
allowed to protect their own areas with the `protect` command (disabled by
default), you should check config.lua and set the appropriate settings in your
server's configuration file (probably `minetest.conf`).
Tutorial
--------
To protect an area you must first set the corner positions of the area.
In order to set the corner positions you run:
1. "/area\_pos set" punch the two border nodes.
2. "/area\_pos set1/2" punch only the first or second border node.
3. "/area\_pos1/2" set position one or two to your current position.
4. "/area\_pos1/2 X Y Z" set position one or two to the specified coordinates.
In order to set the corner positions you can run:
* `/area_pos set` and punch the two corner nodes to set them.
* `/area_pos set1/set2` and punch only the first or second corner node to
set them one at a time.
* `/area_pos1/2` to set one of the positions to your current position.
* `/area_pos1/2 X Y Z` to set one of the positions to the specified
coordinates.
Once you have set the border positions you can protect the area by running:
1. "/set\_owner <OwnerName> <AreaName>"
-- If you are a administrator or moderator with the "areas" privilege.
2. "/protect <AreaName>"
-- If the server administraor has enabled area self-protection.
Once you have set the border positions you can protect the area by running one
of the following commands:
* `/set_owner <OwnerName> <AreaName>` -- If you have the `areas` privilege.
* `/protect <AreaName>` -- If you have the `areas` privilege or the server
administrator has enabled area self-protection.
The area name is used so that you can easily find the area that you want when
using a command like /list\_areas. It is not used for any other purpose.
For example: /set\_owner SomePlayer Diamond city
The area name is used only for informational purposes (so that you know what
an area is for). It is not used for any other purpose.
For example: `/set_owner SomePlayer Mese city`
Now that you own an area you may want to add sub-owners to it. You can do this
with the /add\_owner command. Anyone with an area can use the add\_owner
command on their areas. Before using the add\_owner command you have to select
the corners of the sub-area as you did for set\_owner. If your markers are
still around your original area and you want to grant access to your entire
area you will not have to re-set them. You can also use select\_area to place
the markers at the corners of an existing area.
The add\_owner command expects three arguments:
1. The id of the parent area. (The area that you want it to be a sub-area of)
2. The name of the player that will own the sub-area.
3. The name of the sub-area.
with the `add_owner` command. Anyone with an area can use the `add_owner`
command on their areas. Before using the `add_owner` command you have to
select the corners of the sub-area as you did for `set_owner`. If your markers
are still around your original area and you want to grant access to your
entire area you will not have to re-set them. You can also use `select_area` to
place the markers at the corners of an existing area if you've reset your
markers and want to grant access to a full area.
The `add_owner` command expects three arguments:
1. The ID number of the parent area (the area that you want to add a
sub-area to).
2. The name of the player that will own the sub-area.
3. The name of the sub-area. (can contain spaces)
For example: /add\_owner 123 BobTheBuilder Diamond lighthouse
For example: `/add_owner 123 BobTheBuilder Diamond lighthouse`
Chat commands
-------------
* /protect &lt;AreaName&gt;
Protects an area for yourself. (If self-protection is enabled)
* /set\_owner &lt;OwnerName&gt; &lt;AreaName&gt;
Protects an area. (Requires the "areas" privilege)
Commands
--------
* /add\_owner &lt;ParentID&gt; &lt;OwnerName&gt; &lt;ChildName&gt;
Grants another player control over part (or all) of an area.
* `/protect <AreaName>` -- Protects an area for yourself. (if
self-protection is enabled)
* /rename\_area &lt;ID&gt; &lt;NewName&gt;
Renames an existing area, useful after converting from node_ownership
when all areas are unnamed.
* `/set_owner <OwnerName> <AreaName>` -- Protects an area for a specified
player. (requires the `areas` privilege)
* /list\_areas
Lists all of the areas that you own.
(Or all of them if you have the "areas" privilege)
* `/add_owner <ParentID> <OwnerName> <ChildName>` -- Grants another player
control over part (or all) of an area.
* /find\_areas &lt;Regex&gt;
Finds areas using a Lua regular expresion.
For example:
/find_areas [Cc]astle To find castles.
* `/rename_area <ID> <NewName>` -- Renames an existing area.
* /remove\_area &lt;ID&gt;
Removes an area that you own. Any sub-areas of that area are made sub-areas
of the removed area's parent, if it exists. Otherwise they will have no
parent.
* `/list_areas` -- Lists all of the areas that you own, or all areas if you
have the `areas` privilege.
* /recursive\_remove\_areas &lt;ID&gt;
Removes an area and all sub-areas of it.
* `/find_areas <Regex>` -- Finds areas using a Lua regular expresion.
For example, to find castles:
* /change\_owner &lt;ID&gt; &lt;NewOwner&gt;
Change the owner of an area.
/find_areas [Cc]astle
* /select\_area &lt;ID&gt;
Sets the area positions to those of an existing area.
* `/remove_area <ID>` -- Removes an area that you own. Any sub-areas of that
area are made sub-areas of the removed area's parent, if it exists.
If the removed area has no parent it's sub-areas will have no parent.
* /area\_pos {set,set1,set2,get}
Sets the area positions by punching nodes or shows the current area positions.
* `/recursive_remove_areas <ID>` -- Removes an area and all sub-areas of it.
* /area\_pos1 \[X,Y,Z|X Y Z\]
Sets area position one to your position or the one supplied.
* `/change_owner <ID> <NewOwner>` -- Change the owner of an area.
* /area\_pos2 \[X,Y,Z|X Y Z\]
Sets area position two to your position or the one supplied.
* `/area_info` -- Returns information about area configuration and usage.
* `/area_open <ID>` -- Sets the area open, anyone can interact.
* `/area_openfarming <ID>` -- Sets the area openfarming, anyone can interact only farming mod.
* `/select_area <ID>` -- Sets the area positions to those of an existing
area.
* `/area_pos {set,set1,set2,get}` -- Sets the area positions by punching
nodes or shows the current area positions.
* `/area_pos1 [X,Y,Z|X Y Z]` -- Sets area position one to your position or
the one supplied.
* `/area_pos2 [X,Y,Z|X Y Z]` -- Sets area position two to your position or
the one supplied.
