floating script? : V - Skyrim

You have done, beautiful sails. That's one of the things I'm yet to do (not much a graphical designer myself

) as well as implementing a proper collision detection, moving the player seamlessly and fixing a problem with certain angles while travelling.

Your ship makes me jealous. :drool:

I'm just using the vanilla ships because I have no ability in modelling/texturing. And it looks really weird for a ship to sail without sails!

I can make one with sails like that for you since I'm making one for myself anyway, if Prometheus doesn't want to share.

Thanks, that'd be great! Just a warning though, I don't know if I'll be using it at all. Once I got past the scripting part of my mod, I've barely done any work on it...

I can share but that is specifically designed for Issgard , with the Issgard flag colors , the Frontal figurehead and vertex colors ... Actually the vertex colors where quite a Pain in the.... couse I manually edited every single vertex in the Nifscope ... then got bored and had to do other work in 3dsmax but seems my version of 3dsmax can't import the ship models and so had to use lot of nif work arounds... I was actually trying to implement an animation inside the other like aflag over the ship but couln't make them work .... may be if I could be able to import the animations and bones too I could animate a bit even the sails ... so far no luck and the time required to experiment compared to the possible gains for now are too unbalanced and I am finely settled with this kind of ship that at least rolls and looks like the ship I wanted ....

If I could get you a basic model of a hull shape, could you add sails and rigging to it, oh most excellent modelling person?

(I came up with a basic catamaran-style hull I'd like to sue for an Altmeri Dominion ship in blender, but I know that I svck rear at making realistic sails, etc...I envision the Altmeri as using http://en.wikipedia.org/wiki/Lateen as opposed to the square-rigged Imperial/Nord designs...

actually I took the sail model in the nif files of the bethesda vanilla model ,they are set to invisible so u don't see , I have removed the closed sails , I have exported uvmapped and retextured the sails and set into the the nif back ... but I slightly modified the shape couse they clpped with the ropes , seems bethesda didn't check that the ropes they put all around woudl have gone thorught the sails when opened so I had to redo those too ...

Haha, same for me.
Building a worldspace is so boring.

How much more difficult would it be to set it up so that the boat would also turn back in the direction it came from repeatedly? From A to B to A to B again.

You mean to make a boat sail in a circle? Well I could do it with scripting, but I still don't know a good way to check for collision, so it might clip through rocks, walls, the ground, etc.

» Wed Jun 20, 2012 9:01 pm

Not so worried about the clipping part, since it'd be more along the lines of moving in the air from one floating island to another.

Would you be willing to teach me the scripting needed to do something like that?

The ship sails along a set route defined by a formlist of markers. Once it reaches a marker on the list, it will sail to the next marker. If the next marker requires the ship to turn more than some set angle (2.5 degrees according to the default values in the script above) then the ship make a curve instead of heading directly towards it.

I haven't scripted in a way to turn a ship around once it reaches a port though. There isn't enough room in the ports for the ship to actually make a 180 degree turn while constrained to only turning 5 degrees per second. I might have to settle for just putting a mage on the ship and saying that she's using magic to rotate the ship while it's in place. (I'm already going to have to use that explanation to get past all the ice around Winterhold.)

Please add that to the Wiki so this thread doesn't disappear one day and that awesome script becomes extremely hard to find. Pretty please!

Bethesda actually place the sails? That is excelent news !!!

a less problem for my mod

OK, it took me a while but I managed to make a http://youtu.be/rJCa9zCahWY. I don't know why there's no audio, but it doesn't matter since the point of this is to see the script at work, right?

I sped up the ship halfway through in order to try and cut down on the video size. The trip from Solitude to Dawnstar would have taken ~12 minutes originally.

» Wed Jun 20, 2012 8:49 pm

thats really cool , are u releaseing this as a resource? may be with a tuto on how to setup ?

It woudl be cool to also have some animations like on the NPCs on the boat like doing something cleaning , fixing the ship , budy governing it etc.....

even a rowboat actually woudl be pretty cool ....

» Wed Jun 20, 2012 10:39 pm

I don't see how anyone would need a tutorial to do that. All you have to do is attach the script I posted to a ship, and create a formlist of markers for it to follow.

I don't think it's possible to move navmesh around, and I'm certainly not going to try and navmesh the whole route. I only put navmesh at the spots that the ship will be anchoring at.

» Wed Jun 20, 2012 2:10 pm

whats a formlist?

There is no need to navmeshing. The ship mesh is enough aparently. I had made NPCs follow my character while my ship was moving and they can even fight each other. Didn't add any navmesh and below was only water.

whats a formlist?

Is a list of base IDs. Similar to a leveled list, but only stores objects didn't aply any randomization and you can place different type of objects in the same list.

» Thu Jun 21, 2012 2:32 am

That is awesome. Beyond awesome, really. I just wish I knew what even half the coding meant.

How would you create a formlist of xmarkers?

» Wed Jun 20, 2012 6:13 pm

and can I put other items on the ship?

will they follow the ship movement?

did u use an animated boat or static one?

Havok items might, but you can forget doors or other statics. Each one of them would have to be moved individually, and there's no way you could make them track the right spot relative to the hull.

» Thu Jun 21, 2012 2:22 am

I placed a door on the ship but is part of the mesh , I was thinking to use a NPC as door or a autoload door eventually but I do not need actually a door for my purpouse .. what I wanted was to have some small random encounters after the player exit the cabin , and then after the encounter talks to the captain and keeps the travel ongoing ....

TranslateTo has rotation as well.

I'm also assuming the movement speed is in units/second, since the wiki page says a speed of 1 is almost imperceptible. that could be determined with some testing, and then you could know exactly how long to wait until starting the next idle movement.

Edit: If you want it to be a easier to code, you can move it on fixed paths (like just up and down) without using random numbers.

There is a note on one of the Translate functions in the Wiki that confirms that movement speed is units per second and rotation speed is degrees per second.
