[REL] Campaign layers with zigzagging units

It's me again: Would you consider the default values of your zigzag script as recommendable and halfway realistic?

Thanx, h.sie

Hi h.sie,

realistic? I don't know. Take a look at the thread linked in the first post with the original Japanese patterns. Comparing with these it's not very realistic. However, I think it's definitely more realistic than stock. It just makes hunting and sinking ships less uniform because you don't know in the beginning where it will zigzag (towards you, away from you),... Hunting the (more or less) straight running ships in stock became boring for me.

In one of the old threads a length of around 10 miles was recommended (I don't know nautical or statute). I like 16km because it's the limit of the range of sight in best conditions. So, if you submerge at the range of sight the ship will have definitely changed course when it reaches your position. So you have to guess/predict its change.

Cheers, LGN1

Hi LGN1,

thanks. I'll take 15km. Allow me some more questions. What is the intention behind the "Zigzag in Bay of Biscay" and "Zigzag in North Sea"-Options?

Why shouldn't they zigzag there?

Thx, h.,sie

Hi h.sie,

currently the script checks whether a waypoint is in the rectangle you specify at the beginning. If you want to avoid any potential problems with the land you choose a rectangle that does not cover any land. In principle, you can run the script again and again with different rectangles and in this way 'patch up' the whole map without covering any land. Since this is a quite tedious work, I added two other rectangles (the most heavily used), North Sea and Bay of Biscay (see the map in the mod). So basically you can choose a rectangle that does not cover the Bay of Biscay and choose the option Zigzag in Bay... and the script also adds a zz pattern if the waypoint is in the 'Bay of Biscay box'. You see what I mean? In other words, it just allows you to have more rectangles in a single run of the script.

If your initial rectangle covers the Bay of Biscay or North Sea area you can either specify yes or no. It doesn't change anything. I am sorry for the misleading formulation. It only adds zz patterns to the area if the area is not included in the initial rectangle, but does NOT avoid zz patterns in the area if it's part in the initial/user-specified rectangle and no is chosen. I have to check the read-me and if necessary make this more clear.

To summarize, you can completely ignore the option if you don't care about including land in your chosen area and you make this area large enough.

Cheers, LGN1

Concerning 15km: I think this is fine. However be careful with a too short distance. There might be several problems:

- many waypoints
- it will take some time for convoys to arrange their formation again. Not enough time might confuse them too much
- the offset from the main course becomes smaller and smaller. For an zz angle of 25 degrees the distance is roughly 15km*sin(25). If this distance becomes too small you can easily position yourself just ahead of the contact and will end up in firing range.

I have choosen an angle of 25 degrees because cos(25) is roughly 0.9. Thus, the speed of the ship towards its destination is only 90% of the ship's sailing speed (increasing the time of the journey by a factor of about 1.1 and thus also increasing the danger). I don't think they sacrificed more speed for the pattern. I don't know whether it has any relevance, but if you look at the most simple pattern of the posted Japanese zz patterns you can also see an angle of 25 degrees.

Cheers, LGN1

Just another remark: the distance you specify is an upper limit! If you choose 15km you will see quite a few shorter 'legs'. Maybe down to less than 10km.
