General Discussion / Re: CPU - Cooking
« on: March 15, 2017, 08:32:46 am »
Hi Folks!

Meanwhile, running Firefox 52.0, the values got much better:
Same condition as in thread start, and Firefox shows 3-5 % in free mode, and about 10% in tracking mode.
And in contrary to before, where Firefox used almost only one CPU, now the load is distributed equally to all 4 CPU-Kernels.

Great!

Improvements / Multiplayer Mode Toggling
« on: January 28, 2017, 08:51:09 am »
The simulation starts with multiplayer ON, by default. When clicking multiplayer button, all but my ships disappear from screen. When clicking again, all foreign ships appear, so far so good. But when clicking again all foreign ships disappear shortly, and come back automatically, and do so at every further click. Is this supposed to do so?

Bugs / Ship's Log incorrect
« on: January 01, 2017, 07:42:34 am »
Hello

I noticed some irregularities in Ship's Log:

- Distance:
Sailing from Auckland to Tokyo with QM2 showed 7780 nm in the logbook, Google Maps measuring function only 4995 nm.
The way back from Yokohama to Auckland added another 7637 nm to it, but Google Maps only 4924 nm. The point to point distance in Ships2 navigation chart is 4770 nm each, what is quite close to the real distance, because you go straight ahead to the Fidji Islands, and then a little left to Japan. There is a factor of 1.55 in the Ship's Log.
As an additional measurement, I used the distance from Nuuk on Greenland to L'Anse aux Meadows on Newfoundland, what is with Google 806 nm, and in Ship's log 1197 nm. Again a factor of approximately 1.5.

- Idle Time:
As I rediscovered Ships2Career on 6th October, and I stuck in it every day (hear the whine of my wife), only 100 days have elapsed since then. But in Ship's Log there are ships with Idle Time of 400, 500, and even 1385 days. I have no overview about the times the ships ran really, but the journey from Auckland to Tokyo and back to Auckland took me not longer than 10 days, but in the Ship's Log I can find 32 days.

This is for your records.

Best regards

Bugs / Re: Unable to pass the Panama Canal with the Sun Princess ...
« on: December 20, 2016, 09:01:57 am »
Nothing happens now, because Paul is on the road.

Try following: Go back to sea a few miles, choose course to a Lake Gatun, and set constant speed.
In the navigation chart double click Lake Gatun, where you want to take over your ships control, and note the time to get there.
Then close Ships2 simulation properly, and wait until this time has elapsed.
The Channel Pilots will take care of your ship during this time.
Login to the simulation again, and continue your journey.
You will certainly have to do this a couple of times during journey.

Improvements / Wind indication
« on: December 17, 2016, 06:15:31 am »
Wind indication is not (yet) implemented right.

When sailing with true wind zero, then apparent wind is always shown incorrectly as the half value of the speed over ground (SOG). Direction indication is always ok then. The wrong value may come from the wind speed of 16 kts, that was set as a constant in earlier times?

When cruising with wind of 8 kts from 10°, which you get in Gothenburg and keep everywhere, different results are obtained.

Wind 8 kts from 10°, ship's HDG 190°, i.e. going with the wind
ship's speed SOG (kts)         0     5       10     16     20
aparent wind speed (kts)     8     5,4      3        0      2
Aparent wind speed should be the magnitude of the subtraction of real wind from SOG.

More:
Wind 8 kts from 10°, ship's HDG as indicated

wind from    SOG    wind kts
ahead         20         18     expected 28
portside      22         13     expected 23.4
stb side      22         13     expected 23.4
astern        22           3     expected 14

This is for your records.

Improvements / Compass
« on: December 16, 2016, 05:02:36 am »
The axis of the compass seems to be shifted. When steering exactly 270°, West and East don't aline (see first picture). This is irrelevant if you can use an electronic compass. But ships without electronic compass must be controlled by compass itself, and then it is confusing when West and East are not on a line (see second picture). Especially when wind indicators cover the numbers, for example 10°, you must use the opposite side 190° to set the right course.

Tips and tricks and photos / Wintertime on Greenland
« on: December 16, 2016, 04:06:54 am »
Hello all
My journey from Göteborg over Scotland, Färöer, and Iceland led me to Greenland, where I visited the City Nuuk (the old Godthåb). Then in the Nuuk Fjord, suddenly came ice. Stena Brittanica almost stuck there, but we managed to get free, and could continue the journey. It's cold here! See the pictures.

Dieter

General Discussion / CPU - Cooking
« on: December 07, 2016, 07:31:06 am »
While Ships2Career ran on my computer, I was noticed by loud noise of the fans on a relatively high CPU load. In the following, I investigated which states of the simulation cause CPU and memory loads, and how they are affected by different browsers. For comparison, my standard Firefox browser and the Edge browser, delivered with the operating system, were available.

To get comparable data, I booted the computer before testing different browsers every time, cleared cookies, and emptied the cache. The simulation always ran with the same ship, at the same position, at the same speed.

It turned out that there is no difference between 'full screen' and 'windowed' within the same browser, there is no difference between 'Map View' and 'Satellite View'. But in 'Tracking Mode' a higher CPU load is to be noted, because the whole map must be moved (which also depends on the zoom factor). Even when I quickly moved the map over a larger area manually, no higher load was found than in the 'Tracking Mode'.

There is a clear difference, however, among the different browsers, whereas Ships2Career in Firefox generates 30 - 40% CPU load, the edge browser is satisfied with 13 - 20%.

The data:
Computer: Terra, with Intel i5-3570K @ 3.4 GHz, 64 bit, 8GB RAM,
OS: Windows 10 Home, version 1607, Build14393.447
Graphics: NVIDIA GeForce GTX 660

Browser:
Firefox 50.0.1
Edge 38.14393

Ships2Career:
Anonymous mode
Stena Brittanica, outside the port of Dover, at full speed, course 135 °

                 Free Mode     Tracking Mode     manually moved     Memory
Firefox      30%              40%                    40%                       450 MB
Edge        13%              20%                    20%                       160 MB

This shows how different HTML code is implemented in the different browsers.
I also did other tests with both browsers and got quite different results, with Edge gaining a small advantage. It was tested with Penguin Mark, Basemark, BMark, CanvasMark, and AnTuTu HTML5 test. In addition, I looked to the kernels, and saw totally different loads on them.

Has anyone had similar experiences, or even figures for comparison?

Is the Ships2 code uniform, or optimized for specific browsers?

Or does nobody wants to be bored with this stuff?

Or anchoring. Both will repair damage on the ship, too.

General Discussion / Obstacle race
« on: December 02, 2016, 06:03:53 am »
Through he last incidents on the Suez Canal, I dare to suggest, that to overcome the many small obstacles around the world by the inadequacies of the vector card, a cheat is introduced, which relieves Paul of having to edit the whole world.

I found obstacles at the port entrance of Rostock, and even those near Burgum / Netherlands at the Kromme Ee, that stopped my journey.

Paul can never edit the whole world on players' communications.

I could imagine a switch that allows my ship to continue a few meters, or a certain amount of time, without land water detection.
This switch must be pressed as often as necessary, to pass the obstacle.

Paul, think about it!

Bugs / Re: Comments on wind and offline-sailing
« on: December 01, 2016, 07:35:07 am »
Yes. Offline land water detection is one thing. The other thing I wanted to point out was the faulty behaviour of the mooring function. The ship moved though it was tied up.

Improvements / Re: account login
« on: November 30, 2016, 05:52:00 am »
When logging in with facebook account, only the buttons of the first menu work, i.e. 'Adventures', 'Explore', and 'Ship's Log'. All submenue buttons beneath 'Adventures' and 'Explore'don't work.

Windows 10 (1607), with
Firefox 50.0.1, or with
Microsoft Edge 38.14393.0.0 with Microsoft EdgeHTML 14.14393

Google account is ok in all combinations.

Bugs / Re: Flat world - script crashes
« on: November 12, 2016, 07:27:03 am »
After a nice trip from Southampton over Stavanger, Tromso, North Cape, Kirkenes and Murmansk we went on to Longyearbyen. There I took all the passengers off board. Your former First Officer has hired, and was allowed to cross the edge with the Oasis. At first she was visible for a while in the gray band, but then she was gone.
The menu button, the track button and the multiplayer butten no longer worked. Navigation chart button, fullscreen button and the mute button were all right. The mooring button told me: Slow down ... But Oasis fell into nirvana anyway. Horn and anchor did not work.
Oasis was still listed in the 'ships in game' menu, you could load her again, and she fidgeted as a multiple image on the screen.
Now you can see in this menu that she is still moving.

This is just for reporting.

Anyway, could someone pick up the people there with his ship? They are still waiting for the journey home.

Regards
Dieter

Thank you for your efforts. It really did not bother me, I noticed it by chance, when it was scratching in the harbor.
