NavMarkers

Space Engineers mod to add commands for showing GPS markers as large 3D spheres in the world. Client side only and originally designed for the Sigma Draconis Expanse server to aid in navigating through space and avoiding the 'slow zones'. Useful for marking gravity wells, danger exclusion zones or any other point in space with a radius.

Updated as of Dec 6th 2025.

• Added 'load' chat command. Will force a reload from the data file. Also allows an optional parameter to create missing GPS Markers

• Added double click nav marker in list to toggle active state
  
• Added double click gps in list to add new marker

• Modified 'set' command to first look by index, then by exact Name

Updated as of May 2nd 2025.

• Implemented help show chat commands

Open up a cockpit in the k-menu and look for the new controls. There are two lists, one for available GPS points and one for active markers. You can create a marker from a properly formatted GPS point using the 'Create from GPS' button. In order for a GPS to show in the available list it's name needs to follow some rules:

• GPS name must contain the range in Kilometers in one of the following formats:
  
  • (R-<range>)
    
  • (R:<range>)
    
  • (R.<range>)
    
  • [R-<range>]
    
  • [R:<range>]
    
  • [R.<range>]
• For example 'Danger! (R-10)' as a GPS name would allow it to be selected.
  
• Marker color is take from the GPS color at the time of creation.

The menu to adjust some render parameters can be found using HupAPI. Access it by opening chat and then pressing F2. This will put the text 'Mod Settings' in white on the left side of the screen. Click that to open all mod settings and choose 'Nav Markers' from the list.


Chat commands can be found by using either '/nav' or '/nm' in the in-game chat box. Example: '/nm help'

Current commands: (More to come depending on feedback)

• list: Lists all active markers in chat
  
• add <range> <name>: Adds a marker with radius <range> centered on the GPS point with <name>
  
  • <name> can have spaces but must be surrounded in quotes
    
  • Example: /nav add 100 "Saturn Rings"
    
  • Adds a nav marker with a radius of 100km centered around the GPS point named "Saturn Rings"
    
• remove <name>/<index>: Removes a marker with the matching <name>, or optionally at the given index from the list command
  
• set <range> <name> OR set <range> <index>: Updates an existing nav marker's radius, either by name or by index
  
• toggle: Toggle visibility of all markers. Accepts two optional parameters <index>/<name> and <on/off>
  
  • Example: /nav toggle "Saturn Rings"
    
    • Toggles the visibility of the nav marker named "Saturn Rings" (either on or off depending on what it was)
      
  • Example: /nav toggle 2 on
    
    • Turns on the visibility of the nav marker at index 2 from the list command
      
  • Will first try to find a marker by matching name, then by index and finally by a partial match with the name if no exact match is found. Can be used to toggle/set multiple markers in this way
    
• close: Toggle showing only close / nearby markers. Change settings in the F2 Menu
  
• intersect: Create a new GPS marker at the intersection of the camera ray and active nav markers
  
• load: Loads saved markers from disk. Allows replacing the .dat file with different data and forcing a reload
  
  • Optional parameter of 'true' will create any missing GPS points from the loaded markers
    
• help: Shows a help message
