Tactics Plugin

[Gilletarom]

Tom_BigSpeedy, sorry to bother you,

Some other items that I do not undestand :
- ° Bow up
- ° Bow down

- Stabilizes the surface current 'arrow' in the chart overlay, bearing compass and also the numerical instruments\nLow values mean high damping

- Currently only set up for NKE instruments. Exports a predefined set of up to 5 NMEA records which are 'known' by NKE instruments and can be displayed there.\nRead the manual how to set up the interface connection !

Perhaps use acronymns? Following the Terminology page? If possible have a hover message with the translation?
-- just an idea.

The one detection was the same as yours.
Bkav W32.eHeur.Virus04 20170109

I have Norton Security 2017 on all our machines.
When I compiled this Norton did not complain.
I have done a live up date of Norton and it is current.
Then I did a quick scan and no threats were found.
So this may be a false positive from that service.

Note that none of the other services have found it, including Norton.

--Perhaps we should just use the DLL that you have? Maybe that is best... until we know more! Can you delete my file and add yours with the SHA text file uploaded to Tactics_pi directory?
Thanks.

Rick,

I think it's a false positive.
The package is created with the standard OpenCPN package creation process.
It's only copying tactics_pi.dll to ~OpenCPN\plugins directory, and creates a subdirectory "tactics_pi\data" in the ~OpenCPN\plugins directory, and adds the 3 icons there ... Standard for all plugins ...

I uploaded tactics_pi.dll as well as the 3 .svg plugin icons in Virustotal.
All 4 were checked OK with no hits.
Or there's something suspicious in the NSIS installer itself. But then it's in your NSIS-Installer as well as in mine ...

Gilletarom,

I will answer tomorrow in detail.

Gilletarom,

° Bow up : degreé proue inclinée vers le haut
° Bow down : degreé proue inclinée vers le bas
This is the display of the "pitch" (Tangage du bateaux) instrument you asked me yesterday


- Stabilizes the surface current 'arrow' in the chart overlay, bearing compass and also the numerical instruments\nLow values mean high damping
This is the "tooltip" = explanation (or "rollover windows" as Rick called it ) for the "Current damping factor" you asked me yesterday :


-Currently only set up for NKE instruments. Exports a predefined set of up to 5 NMEA records which are 'known' by NKE instruments and can be displayed there.\nRead the manual how to set up the interface connection
Another explanation :


You can define up to 5 NMEA183 records, which are created then by the plugin. You can export these NMEA sentences (like autopilot data) and if you have a NKE instrument system on your boat, you can display the data in your instruments.



I hope this helps,

Thomas

PS : Thanks again for your help

Unless I am mistaken, it is not currently possible. However, this is possible in the Dashboard plugin displays.

If possible, could you do the same, moreover, this will also make the instruments more readable.

Best regards, Gilletarom.

Gilletarom,

tactics_pi is derived from (a copy of) dashboard_pi and has some additional functionality. But all the basics is the same, including resizing ...
Just have a look ...


Polar Performance, Wind History and Average Wind are standalone instruments, just create them like this


and you can quickly show and hide them as needed with the right mouse button ...

Once you have defined them, the data is collected in the background even if you hide them ...

Best,

Thomas

I can not open the file "tactics_pi.pdf." My pdf file reading software tells me that this file is corrupt.

What are they used for?

Gilletarom.

Gilletarom,
this is the documentation of the plugin, Libreoffice document(.odt) and the same as PDF.
You can also find it on github :

I resurrected my old laptop which is out of use since early august, rebased, compiled and created the plugin package again.

Result : Virustotal reports exactly the same thing.


As I get it on 2 of my machines which are more or less independent, and also Rick encountered the same finding on his machines, either the nsis installer itself has a virus or it's a false positive.

As we already created lots of packages with same nsis installer version,
I assume it's a false positive...

PS : I did check the nsis installer setup programs (nsis 2.46.3 and 2.46.5) yesterday as well. Before my upload to Virustotal they had been checked there with idenitical SHA256 last time in 2014, with 0 hits.
Now both report 2 / 3 heuristic hits ...

I still think it's a false positive.

Hi there,

as we still have this weird "virus" issue with the installer package, I created a zip file tactics_pi_win32.zip and uploaded it to Rick's file thingie
https://tgp-architects.com/files/index.php
rguser, rgpass

This was checked with no findings in Virustotal
see virustotal_tactics_pi_win32.zip.txt
The installation is not fully automatic, but better than nothin' ...
Installation :
1. Navigate to the plugin directory of your OpenCPN installation
<intallation-path>\OpenCPN\plugins and copy the zip there
2. unzip DIRECTLY INTO the plugins directory.

If everything's fine, you should see

<intallation-path>\OpenCPN\plugins
+ tactics_pi.dll
<intallation-path>\OpenCPN\plugins\tactics_pi\data
+ Tactics.svg
+ Tactics_rollover.svg
+ Tactics_toggled.svg

That's it.
I hope that helps ...
Thomas

Thank you. I will work and so I think that I will try to write a page of French tutorial shoreline for OCPN, about Tactics.

Perfect, thanks

Working on the Dutch translation, the following strings in English are not clear to me:

1. True Compass: is this the course steered as indicated by a magnetic compass and corrected for variation and deviation?

2. This formula requires a description before I can understand what it means: Diff. angle to Target-VMG/-CMG + corresp. gain

3. Same applies to this formula: Target-VMG angle + Perf. %


4. I don't understand this sentence from the manual: "Actual Course Made Good = aka VMC; speed towards a waypoint." A speed cannot be described with the term course in my opinion.

Hi,
1. True compass :
this is identical to doasboard_pi, a dial instrument showing a compass with true north.
This is a magnetic compass + correction for mag. variation. The deviation is handled inside your compass,
when you do the compass correction.

2. Diff. angle to Target-VMG/-CMG + corresp. gain :
This NMEA record holds 4 data values ;
* Diff. angle to Target-VMG [°]
* VMG gain [%]
* Diff. angle to Target-CMG [°]
* CMG gain [%]

The "difference angle to Target-VMG" is the difference between your actual True Wind Angle (TWA)
and the optimum (Target-)VMG angle.
Example :
Let's say you're sailing upwind, 50°TWA, 4.2 knots actual VMG . According to your polar, at the given
True Wind Speed, the optimum angle upwind is 45°, and you be able to do 5 kts VMG @ 45°
"diff angle to Target-VMG" is -5°, gain would be 16%

The same applies to "Diff angle to Target-CMG" ...

3. Target-VMG angle + Perf. %

This is the Target-VMG angle, the optimum true wind angle upwind, and the percentage of your actual VMG speed to the Target-VMG speed.
Take the example above :
Target-VMG angle = 45°
Performance % = 84% (4.2/5 * 100)

4. "Actual Course Made Good"
We had this discussion already a couple of times ... but due to the fact that we didn't make it to a common, agreed definition here,
I'm sticking to NKE's interpretation of CMG (Course Made Good) as the speed made good towards a waypoint.
If you google the internet, it's not only NKE using this term. Others call it VMC=Velocity made good on course (to a waypoint) ...

See the picture for explanation please.



Consider the arrows as vectors, length = speed
The boat heading/speed the black arrow (vector), direction = NE. length is STW
True wind is blowing from North (TWD)
A waypoint is on NNW.

Draw a line from boat position to WP.
From this line draw a perpendicular line to the tip of the boat vector.
The length of the green line is your actual CMG (=speed towards the WP).

Similar situation for VMG (speed upwind), just exchange WP with TWD, and you get the actual VMG speed.

BR,

Thomas

Thomas, Thumbs up I like your graphic, and am happy with CMG

Thanks for the explanation, Thomas. I did understand the principles of point 4 and the vectors involved. However, it's strange (and I stick to that point ) to use the word course to describe a speed. But if that is common usage in yacht racing, who am I to reject this. For the Dutch translation however, I'll try to find more accurate descriptions (generally I'll try to follow Bowditch and comparable books in Dutch), although the lengths of the Dutch strings involved might become a problem.
