TacView 1.x Updates


For those that do not know, TacView allows you to record, analyze, replay and stream tracks created in:

With the Advanced and Enterprise versions, you can also do on-line debriefings. Pretty cool.

I’ve had it for a number of years and it is really useful to take a look at engagements and see where I went wrong. At times it can be a little complicated and, for DCS, server admins need to enable the export, otherwise you get nothing useful.

Anyhoo, there’s a new update which seems very promising with hints at an upcoming ability to rate your carrier landings without having the judgement of others … unless they have the track, and then you are out of luck :-).

I will see if I can’t keep on top of the updates as they become available.

Tacview 1.7.2 is available

Time to get your hands on the brand-new Lua SDK!

This release is a big step forward more customization: I have integrated Lua 5.3.4 in Tacview and started to develop an easy to use API. Now, anyone with some programing skills can create addons to extend existing features and even add new features to Tacview!
How to create your own addon?

  • Create a sub folder named after your addon in C:\ProgramData\Tacview\AddOns\
  • Create a file named “main.lua” in this folder (it will be automatically loaded at Tacview startup). It will look like C:\ProgramData\Tacview\AddOns\My Addon\main.lua
  • At the beginning of your script, reference the latest API like the following: local Tacview = require(“Tacview172”)
  • Now you can use any of the features documented in C:\Program Files (x86)\Tacview\AddOns\Tacview Lua * Interface.txt to create your own addon!
  • LuaSocket 3.0 which has been integrated in Tacview and ready to fulfill all of your connectivity needs! Just reference it as usual: socket = require(“socket”)

Keep in mind that this is a first iteration. While the current API is still relatively limited, new features will be added over the coming releases. Just let me know whatever you need. I will do my best to add more Lua functions, so everyone can develop the addon of your dream.

Have a look at the samples are available in C:\Program Files (x86)\Tacview\AddOns\

The most notable example is the Landing Signal Officer (currently in development) which (will) displays an LSO view when you select an aircraft carrier as switch to cockpit view. This addon will soon automatically score landing attempts.

Notable improvements for DCS World

A new option has been added to DCS World option page: Terrain Export .

No need any more to wait for a new release of Tacview every time a map has been updated! Simply select [ Predefined Terrain ] if you want to re-export a terrain which has already been integrated in Tacview, or [Unknown Terrain] if you want to export a brand-new map. Then launch a mission in the center of the map and wait patiently for the load to complete. The exporter will automatically export all the surrounding tiles in C:\ProgramData\Tacview\Data\Terrain\DCS World\

It is a long operation: It will look like DCS is frozen at the end of the mission load. This is normal, just wait for 1 to 10 minutes (depending on your system) for the terrain to be exported. As soon as you are in the mission, return to the main menu and disable the terrain export feature (to not wait 10 minutes the next time you launch a mission!).

Now, the next time you will launch Tacview, it will display the terrain tiles you have just created!

This very feature was used to integrate the Persian map in Tacview and to update the other maps with the latest version of DCS World. Some airports may not be visible, this is normal, they are not part of the terrain, they will be manually added in future updates of Tacview.

What’s next?

My current plan is to continue to update Tacview 1.x and to use it as a test bed for the new features which will be available in Tacview 2.x.

Indeed, I have started to work part-time on Tacview 2, working first on all the necessary tools to develop it. The goal is to offer you an even more intuitive, fresh and modern UI, a smoother experience on low-end systems, and easier and more customization possibilities, on all platforms: Windows, Linux, macOS, iOS, and Android.

That way, you will not have any excuse anymore to not review your last mission, on you cell phone, in the bus, on your way to work.

tacview is very cool, and for what it does, very cheap too.

Simply outstanding! I love this little piece of software.

With the API, this might be a cool plugin to create:

Definitely…although the app on Mudspike works pretty good.

The ELINT record that the Viggen spits out is a very basic text file.

The new LSO add-on is fantastic:

The noob

The best about it is that you can rewind, slo-mo, add telemetry and show you whole football fields with areas for improvement…


That’s so cool!
