About this Mod
BlueMap Sign Markers
Overview
Fabric plugin for BlueMap that displays markers based on in-game signs
Installation
Place in your mods folder along with BlueMap.
Server-side only.
Usage
Place a sign or hanging sign with the following text on either the front or back:
[poi]
<short description>
A marker will be displayed on the map at the location of the sign with the text <short description>. The marker will
be removed from the map when the sign is broken.
Note that the prefixes can be configured in the configuration file.
Configuration
The mod will create a BMSM-Core.json file in the config/bluemapsignmarkers folder. This file contains the following
options:
markerGroups- a list of marker groups (described in detail below); default is a list with a single marker group
configured for the[poi]prefix.
Marker Groups
A marker group is a collection of markers that can be toggled on and off in the BlueMap UI. Each marker group
configuration contains the following options:
prefix- prefix that the sign must contain to be included in the marker group; required;matchType- the type of match to use when checking the first non-empty sign text line; optional; default isSTARTS_WITH(case-sensitive exact match);STARTS_WITH- line must start with the prefix;REGEX- line must match the regular expression (uses Java regex engine);
name- the name of the marker group; required;type- the type of marker to display; optional; default isPOIicon- the icon path or URL to display for the marker; optional; default isnull(BlueMap default POI icon)offsetX- the x offset of the marker; optional; default is0(corresponds withanchor.xin BlueMap base configuration)offsetY- the y offset of the marker; optional; default is0(corresponds withanchor.yin BlueMap base configuration)
Example
{
"markerGroups": [
{
"prefix": "[poi]",
"name": "Points of Interest"
},
{
"prefix": "[store]",
"name": "Stores",
"icon": "assets/store.png"
},
{
"prefix": "\\[[vV][iI][lL][lL][aA][gG][eE]\\]",
"matchType": "REGEX",
"name": "Villages"
}
]
}
This example configuration creates 3 marker groups: one for [poi] signs, one for [store] signs, and one for signs
where the prefix is a regex match for villages (e.g. [Village] or [VILLAGE]).
The [poi] and Villages marker groups use the default POI icon, while the [store] marker group uses a custom icon
located at assets/store.png.
Signs with the [poi] prefix will be displayed in the "Points of Interest" marker group. Signs with the [store]
prefix will be displayed in the "Stores" marker group. Signs that match the villages regex will be displayed in the
'Villages' marker group.
