If enable in config.lua you will be able to pause/unpause/stop the mission directly from LotAtc client

Add opacity slider for filtered objects
All settings are now saved in %appdata% directory (Users directory), no more in register
User can export/import settings
Add toggle mode for measure line, first click will start measure, then just move the mouse to get a BRA, click again to hide it

  • Ctrl+click to maximize/restore
  • Shift+click to maximize/minimize

Fix UniversRadio ID on airports
Lots of fixes…


Rework of radar modelization

  • 2 modes:
    • Global: all available radars make the total radar coverage as in LotAtc 1.X
    • Monoradar (WIP): Each controller will have to choose the radar to use, it will get only contacts from this one (later coverage will be completed by datalink simulation)
  • Add RCS simulation: all items (planes, heliccopters, missiles…) will be computed and displayed if radar can see it using their RCS resolutaion and item own RCS
  • Add Radar resolution : if enabled, radar will not see items near each other, only one track could be made ( for example 3 aircrafts separated by 20m will be seen as only one contact)
  • Add spot/track management : radar will first see a spot with no data, then after a while (for example 6s, could be csutomized) if the spot is always there, a track will be made on it (and have data as speed, hedaing, symbol…)

All theses options can be enable/disable in profile lua file (see profile/custom.lua for more help).

Better support for dedicated server

  • Enable dedicated_mode in config lua
  • No more need to edit Config/Options.lua
  • Put your licenses in Saved Games//LotAtc Data/Licenses/ In config.lua, enable dedicated_mode, no more need to edit Config/options.lua, just install LotAtc mods now in dedicated saved games directory

Add more control to controllers login
Server admins can now:

  • Blacklist/Whitelist Ips (there is still some troubles with IP6 support)
  • Add specific username/password that will be authorized to connect with LotAtc
  • Enable/disable old login way by standard passwords (blue/red one)

Fixes enemy type not correctly reset in realistic mode
When no controllers are connected, footprint of LotAtc server (CPU/RAM) have been reduced
Update internal librairies
Lots of fixes…
