that actually sounds very interesting and would be totally awesome

This would be great!

Looks really good, i forward this

Looks like a really good idea.

It would be great if you had an 'end mission at sea' function maybe 100kms from port like in the other Silent Hunter games. This would also be good for those with older computers, who have problems with ctd's close to port.

Off topic: why the crashes occur going into port more than going out of port? I'm just curious.

Hello,

I've made a first test with a route from Wilhelmshaven to somewhere near the Faroe Islands.

I think it works fine, but I cannot travel with a TC above 512. The game misses the next waypoint and Your sub goes straight ahead until You will stop it.

In the screenshot below You see, that I haven't started the route frome Wilhelmshaven. I have entered it from the Skagerrak. I went there with the Skagerrak-pilot from Kiel. I have activated the Marschweg-Autoscript and the sub found the nearest waypoint there and headed to NE.



Near Bergen, I have travelled with TC 1024 and the Pilot missed the next WP. So I deactivated and reactivated the scipt on a low TC and it found the next one and resumed the given route.

The parameters for th sha-file are:

[TITLE] 
Marschweg  
[TITLE_END] 
[DESCRIPTION] 
Ihr Steuermann lässt das Boot auf diesem Weg in das befohlene Zielgebiet marschieren 
[DESCRIPTION_END] 
[PRECONDITION] 
0,0,0 
[PRECONDITION_END] 
[WAYPOINT_RESUME] 
50000 
[WAYPOINT_RESUME_END] 
[BUFFERZONE] 
2000,0,2,3,1000,3,2,1 
[BUFFERZONE_END] 
[WAYPOINTRADIUS] 
1000,2000 
[WAYPOINTRADIUS_END] 
980887,6427730,-1,9999,9999,9999,-1,Start  
970000,6445000,-1,9999,9999,9999,-1,WP 1 
960000,6500000,-1,9999,9999,9999,-1,WP 2  
950000,6600000,-1,9999,9999,9999,-1,WP 3  
920000,6700000,-1,9999,9999,9999,-1,WP 4 
....

In my opinion the values are working fine, but perhaps there are some suggestions from Your side.

The testversion with this route: http://www.mediafire.com/?5a768oo2o45j6br

Because it is dull to work with the Mission-Editor for finding the needed waypoints, I'll need some help from You

The game messures from
x-achse -21 600 000 metres to -21 600 000 -> 43 200 000 metres=pixel
and
y-achse -10 800 000 metres to -10 800 000. -> 21 600 000 metres=pixel

I have converted the large map file into a bmp file. But I got an ugly picture where I cant distinguish land from water. Perhaps someone could convert this file for me. I want to draw the lines in this picture for getting the x- and y-position ingame. I think the resolution from 1 pixel = 2000 m is exactly enough for defining the sub-routes.

If needed, I have an 80 MB PSD File from this map. Please PM me for the link.

Thanks,
Paco.

Hi Paco - looking good so far
Some point to consider:-

[BUFFERZONE]
2000,0,2,3,1000,3,2,1

Here the first param is the detection radius for a warning message
You could use this as your lookout calling a contact. If you set this at say 5000 or 6000 and then set param 3 to 2 and param 4 to 9999 - the result would be:-

A ship within 5 to 6km will cause TC to drop to x1 and a message to display and speed to remain the same.
This could be a nice way to let us retake control of the boat if the ship is a target

I think it works fine, but I cannot travel with a TC above 512. The game misses the next waypoint and Your sub goes straight ahead until You will stop it

To get around this you can (and I have done this many times) just add extra waypoints in between so that they are smaller leg runs.

An easy way to get the coords is to run your script with the game in windowed mode. At the same time run dbview as it will give you lots of info anout what navigation is doing. So as each leg runs through - dbview will give you constant feedback as to how far to the next way point check (x4 for non precision). When you are at the halfway point - get a new fix from the nav officer and insert that into your script.

Do try to run dbview at the same time as it helps a lot

Thanks Trevally, that helps me a lot.

What am I doing now? I'm writing a script in Python which is calculating the waypoints between, I called them, masterpoints. Masterpoints are waypoints where the heading of the sub will change.

I hope, that I will finish the work with this script in a few days. I want to have the following features:

• reading from a file within only the masterpoints
• calculate all needed waypoints between start and end over the complete sub route
• the calculation is based on the given value for the max. distance between two waypoints. For example 10,000 or 5,000 m. If the distance between two masterpoints is 100,000, we need 9 or 19 calculated waypoints
• all calculated waypoints draw straight lines between the masterpoints
• determine the angle of the course to add comments to the waypoints. For example" Heading NNE, Herr Kaleun" for an angle of 10 degree. ( I hope I'll get that to work )
• writing the whole SHN-File by executing the script

I know, that needs some time to do this, but I think, for later tests and modifications it makes sense. We are able to define the masterpoints in a textfile and the script will do the calculation for the needed SHN-file. After that, we are doing tests with different speeds and TCs and if we'll get in trouble, we'll change the Parameters for distances and will doing a recalculation for the files.


Over all, I think this method will decrease time to build new routes. It will be easy to define long-range routes with only a few given masterpoints and the scipt hopefully will do the rest for us.

Ah, the script does this calculation not ingame! Its only for building the files before releasing the mod or for building new routes befor activating them via JSGME.

Greetings,
Paco.
