Those are the unfinished lifts. I have to remove the blocks on the upper yardarms and change the main yard up to use a sister block and attach to the block instead of the masthead. Once that it done I will mirror it on the other side,
Good eye.

No Canvas.. spars lowered to mastheads

Testing some mast damage.will need to address why spars and rigging loses center attachments...
It was still worth a test to see what I need to improve on for rigging damage.
Attachment 37271
better.. still need to reorder mast and sail layers to remove the strange spar overlap. Also need to sag the cordage appropriately. but time for bed.. working nights.

May 8th update: I’ve been working on node.js and socket.io to get a rudimentary server working. Planning to have a simple server working that moves ships around in real-time soon. Once that is working I will get interprocess comms going with my sailing physics engine. I have a steep learning curve at the moment so I’m working on simple processes.
All I can say is bravo Aaron.:question:
Bligh.
Thanks it’s been a journey. I have a server that runs now and a client that connects. Currently the server is sending positional updates and the client moves the ship along and angles the yards. I have to add multiple ships and have the server update the appropriate clients. I am getting close to having a test webpage that you guys can try out.Quote:

I’m glad you found the improvements helpful. This new evolution is an experiment on online multiplayer. I still have more to do for the original app but I want to tackle how online works out with my direction first.Quote:

So what this is is client side code development in progress. I am getting some basic objects created and the view camera working properly and prelim level of detail coding. The next phase is to get a basic server sending the client updates. Once that is done I can add in the sailing physics and other stuff that I’ve developed along the way.
Zoom up showing ships. Row boats are drawn as separate objects here so they can be utilized. Yards can be rotated separate from base for animations.
Attachment 38009
I can only stand back and admire your programming skills Aaron.
This is really starting to look like a first rate production.
Rob.
I can only claim to dabble in programming, I'm not even an 'able' crewman.Quote:

Nevertheless, Aaron it gets more impressive by the day. You will be building in the amount of sea time and effect of Barnacles on the bottom before long!:wink:
Rob.
I tried a capture program called snagit to record some video. It caused some video blurring on quick zoom changes and it didn't capture at 60fps but at least some motion was captured. Here I was testing some boat launch and recovery code plus some cannon shots at the end.
https://youtu.be/OEVatj18Y5U
update: It's been awhile since last update but the programming hasn't stopped. I'm building up the world on the client side and I added the start of a fort. I've got the camera, zoom, slide working pretty well on the browser. I'm now working in a few ports as stopping points and large scale map functions like plotting courses and such. It's getting closer to being 'sea' worthy for a trial.
Start of a fort:

update: 6/18/18
With busy weekends (father's day, etc) I couldn't dive into any of the heavy remaining tasks but I've been tweaking the look of the land/sea and I've since added hill sides. Towns are next to place down as these will be the hub of coming/going out to sea for ships. I'm going for historical layout obviously but not to the point of stalling progress.
Current coast in game:

You are really getting things in place now Aaron. it is enthralling to see how you are fleshing things out.
For a non programmer I am really enjoying your demonstrations.
Rob.
Thanks! One thing I am noticing is the land changes from 17th century to now. Lots of filled in areas now where it was water before.
Yes it is fascinating to see just how much reclamation has been achieved and how much silting up has taken place in 200 years Aaron.
Rob.
Update 7/14/18: I managed to get all of the sailing physics code I wrote in the original C# translated over to JavaScript. I think it will be better in the long run than trying to build a link between the two programs. It is even running at 60 frames per second without optimization so that is very good news. I’m in the middle of setting up crude controls so I can sail the darn thing.. at slow speeds the rudder doesn’t answer so I have to get the yards, jibs and driver working together.
I added the beginnings of simple graphics for a Quay for ship loading activities.
Short term plans are to translate the mast and yards code I did in C# so the ships rigging can be wrecked and shredded in real time on the client side.
Progress is slow and steady but it continues..
Good to hear your progress Aaron.
Please keep us informed.
Rob.
On my lunch break, went out for a cruise in a frigate in the West Indies. The black line is the apparent wind direction (wind was 30 kts out of the east), the grey near vertical line pointing upwards off the page is the ship's velocity vector (not exactly the bow heading as leeway was around 6 degrees, the bow was pointing more windward).
I was close-hauled west of Martinique heading east to Fort Saint Louis. The large radius circle represents 15 miles (extreme spotting distance for other ships), the smaller inside circle is a mile (long cannon range).
Attachment 38859
I made several tacks back and forth, beating against the wind and was feeling confident until I approached the anchorage NE of the Fort which presented a lee shore.
I underestimated the momentum of the ship and just backed the sails in time and came close to running aground, but with no speed the ship lost rudder steerage way and the wind pushed the ship westward.. in a panic i let the sheets fly but I had already started drifting leeward and into the shore I went.. it didn't help that I had no anchors aboard...
Attachment 38860
The captain may have been distracted, combing the beach with the scope. The sailing aspect of the program is getting to be a fun little challenge. I need to add in the current model soon.
This is starting to look challenging Aaron, but it will undoubtedly teach us how to not sail a ship. It is easy when you read the theory, but I doubt if I could pass my Lieutenants exam.:happy:
Rob.
8.29.18
Working on jib and driver.. kinda neat seeing the ship yaw about. Wish I had more to show but this is a busy month. As before black line is apparent wind (true is out of the east), gray is ship velocity direction, white dots are past positions. Cheers.
Attachment 39414
Coming about.. in stays. jib hasn't been handed over to other side.
Attachment 39415
On new tack..
Attachment 39416
8.30.18 - Visuals on Studding Sails are in the works. The sail masking code is now in development. This should make sail choices and bracing angles interesting. Following that it will be sail/yard strengths vs wind.
Attachment 39428
The spanker is in kind of weird angles, but perhaps I'm misunderstanding from where the ship is coming and going and to where it's tacking.
It’s not easily moved yet, need to bind angle to a key. Thanks for looking into it.Quote:

I better hone my closing skills.. I had this one and messed up the approach.. better luck next time.
edit: we met up again and this time it wasn't target practice.. enemy ship on left lost the fore sails so I caught up.
Attachment 39674
ship on the left missed stays because no one was manning the braces. the visual sail shape was static at the time and didn't reflect aback but it was in the physics.
Attachment 39675
Something I've been working on over the last week is how ships used their anchors and the physics involved. I have a single anchor working at the moment. It will drag along the bottom if pulled on too much, once it has a good bite it will limit the travel of the ship around the radius but the ship can still rotate and shear around with the wind and current. The cable can be hauled on and the ship brought above the anchor point where it will then win the anchor. I am going to add a second anchor to allow a mooring setup and a spring cable to control the ship rotation. You can also slip/cut the anchor in emergencies. This was a detail I wanted to capture rather accurately. I will consider it a success when the anchor physics is adequate to perform a club-hauling emergency maneuver.
Here's a quick shot of a ship under a lee shore just securing the run of cable. (the white line). The gray line showing velocity direction is now tangent to the anchor line thus confining radial position to the anchor point.
Attachment 39697
My word Aaron, club hauling is certainly an advanced technique. I have only ever come across its mention a couple of times.
Rob.
