but how about flyable ones? Here is what my lil big o coding as amounted to, the ability to fly using pitch, yaw, and roll by keytrapping the player's pitch, rotation, and sliding respectively. You guys are free to use this to build upon, just give credit.
The yaw might be backwards from what you're used to, but I just wanted to see who liked it more this way or prefer the "normal" way.

Anyways, heres a few screenies, tho prob don't quite do it justice, so I posted the zip of the level for you guys to play, there are a few things.

1st - You MUST run it with its own folder because it has to change weapon cogs and inv, etc.

2nd - You will find it works only in multiplayer because SP was giving me problems w/ triggers.....

3rd - I'd suggest using a joystick

4th - rudder (see above)

5th - There are two helos, the one to the right is configed for truely flying around the vast space, whereas the one on the left is more designed for actual helo fights, tho not quite tweaked right yet and still more to go.

6th - Don't press crouch or another weapon or die or play with more than 1 (for clarification, ONE) person. This is not yet coded for multiple people (tho it might work), and the disembarking is not yet set either.
To rephrase, its far from perfect, but you can still fly around.

7th - Enjoy and tell me whatcha think.

no one has tried this yet?

I'll have to try it when im not sleeping or working.

is this like the other flying vehicles mod.. using outer space, or actually feel like you would be flying with the rules or gravity?

There are actual rules of gravity. I made the system based upon real life physics equations (sum of F=ma, F-drag = -kv, force of lift = UVec, gravity = 0 0 -4 [which is what I guestamated the accel of grav constant for JK to be], etc) Theres no collide destroying etc since I'm showcasing the actual flying aspect. It flys just like the helos in Battlefield and real life helos (tilt it forward, it goes forward, closer to the ground, more lift, etc). Its physics corruption in pure form tho too lol.

I'm trying this the moment finals are over.

FIXED

hahahaha

no, theres still guessing involved lol

Estimated* first of all.
Second, the gravity of JK IS -4.
I've tested this in JK.
And it does make sense then, since the default value for grav in JK is 4.

PHALLIC SYMBOL

I always turn the gravity up in my levels.

The you'd better turbocharge your helicopter!

Well, if it *IS* 4, then its not even an estimation.

Here's something you may want to take a look at. http://www.jkhub.net/project/show.php?projid=102
I bet the keytrapping system I made could come in handy for you, even if you just use pieces of it or ideas from it. You have my permission to use it if you want (credit is nice ) and if you have any questions, I'm more than willing to help you out.
I've spent almost a whole year on and off working on key trappings, so feel free to pick my brain.

As I said in the other thread SG-fan, lets combine ideas more or less, (contact me AIM - DPatMassassi) since mine takes into account for when the player reaches the maximum pitch, as well as was designed for if the player didn't have an LVec parallel to the XY plane. I did think of alil change to it, to correct for if the player is inverted, but I'm thinking of possibly simplifying it because I also had the thought of "why even move the player itself, update it to where the vehicle "dies" or when exiting." Me smart, I know.

Ya, mine has the player stationary. But I use the AI verbs to reset the pitch so I never run into the upper/lower pitch limit.
Having the player stationary simplifies a lot of things to do with getting the pitch and yaw since you don't need to worry about the x/y plane not being parallel.
The camera system is also much better if you use a ghost instead of the player himself in a ship. It can do a full 360 without any problems. and you don't need to worry about the player mysteriously dying from a random collision error.

Yea, I'm using a ghost camera system for the viewing, cause even collide=0 had problems. *shrugs* its JK's nature I guess.
