driveable vehicles..
[http://67.87.115.203:81/brad_s/temp/jeep-cog.jpg]
activate vehichle with spacebar, switch from walkplayer to jeep.
Controls: Same as walkplayer - drive=forward, reverse=back, turn=arrows
Exit by spacebar again..

Has this been done? can someone help me out here?

That's funny.

Let me clarify. This isn't as simple as it seems. Pressing the left button in game now makes you turn on a center axis. Perhaps you could offset the center, but even then, no vehicle can turn 180 without moving in any direction. So you'd first have to disable this. Then you'd need to incorporate acceleration, or there'd be pretty much no use for the jeep. Then it'd need physics different from the player in many ways. Lastly, good luck on giving damage when hit by this thing.

I was looking into that at one time. Seems there was a POC map with drivable vehicles. It worked a lot like the jeeps in BF1942. The only difference was that it didn't change the walkplayer model. It attatched the walkplayer to the object...so the walkplayer was sliding around a bit while you were trying to drive the hoovercraft.

Jedikirby, YOU. CAN. NOT. COG.

Never give out advice on cogging, kthxbye.

As far as driveable vehicles go, apparently Cave Demon made a hoverbike level or something - the level screams 'driveable vehicle' like crazy, I don't see why it couldn't be done.

Hell, all you'd need to do is run a pulse that checked player speed and then decided whether he could turn or not.

There's flags for this somewhere in datamaster - no turning, limited turning, and normal turning.

Check it out.

actualy the best way would be to set the players pos at the center of the jeep (as long as the center of the jeeps been corcted in JOKE..

then all you have to do is give the jeep a 0x8 attachment (through attachthingex()) to the palyer, and finaly set the players actor flags 0x10 to make him invisable.

i have done it and had acseptable results, unfortunatly i resently had a virus that destroyed all my files, and i dont ahve the code.

oh, and you would have to use parsearg to extend the players collid sphear to encompas the vehicle and change the maxvel and maxrotvel.

But at the same time, you couldn't give the jeep any real vehicle physics.

As for Cave-Demon's code, which I showed you, and edited, myself, it's extremely unlike a vehicle in every way. It couldn't turn normally, and it didn't have any falling physics.

There's no real way to do this. The wheels are where the problem lies. Hellcat told me once JK needs basic trig to calculate wheelspinning/turning. But, I will say that a hovercraft-type vehicle would be doable.

could you have it play .keys when it moves and stuff, like the wheels spinning and when you turn, have the front wheels turn? would it work in mots only, both, or neither?

Heh, I love the simplicity of the descriptions of drivable vehicles. Dont take this personally guys, but theres alot more to making a jeep cruise than just attaching the vehicle to the player.

Not so long ago I started out on a 'realistic vehicle cog'. Having done a fair amount of physics and vehicle analysis I thought that I would have a head start on everyone else. Unfortunatly I ran into a major problem - its called physics in JK. The lack of mathematical support for things such as basic trig meant that accuratly calculating turning etc was impossible.

The current drivable vehicles dont allow for any forms of realistic handling. Its just your standard player physics except the player can run realy fast.

Now thats just for turning...

You really need to consider things such as the vehicle rolling over, shock absorbers, weight distribution etc

Using fudge factors and alot of time I am sure you could come up with something 1/2 cool. But never anything near to the standards of bf1942 etc.

But you never know, during my holidays I *may* try again.

but my lowering the maxrotvel you can slowdown the turing of the vehicle.

and also could i point out that that you can find the velosity of the player?

now would it therefor not be simple to link the MAXROTVEL of the player to his velosity? their by slowing the rotation dow the slower the player travels util at a stadstill he just cant actualy rotate?

somthing like this..

if(velosity>=6) parsearg("maxrotvel=3);
if(velosity>=4) parsearg("maxrotvel=2);
if(velosity>=2) parsearg("maxrotvel=1);
if(velosity==0) parsearg("maxrotvel=0);
if(velosity<=2) parsearg("maxrotvel=1);
if(velosity<=4) parsearg("maxrotvel=2);
if(velosity<=6) parsearg("maxrotvel=3);

ad so on...

also (correct me if i am incorrect as i dont have DM here) if you can find the rotaial vector of the player couldent you i turn increase the actual roll of the player the further you turn? then if its above a certain about play a car rolling over key and kill said player (after addig the good old cutseen play frease flag)

as far as i see so far there is no need for trig... but i have been known to be wong..

I dont think I said you couldnt did I? [http://forums.massassi.net/html/confused.gif]

Last time I checked maxrotvel doesnt effect mouse movement... nor does is stop straffing.

You also need to consider turning circle relative to wheelbase etc. Also if you want a tiny bit of realism you need to add skidding when you turn... so if you turn to hard the back of the car drifts. All trig stuff.

Trust me, your not getting anything but a poor set of fudge factors that pretty much sets up a kyle that runs really fast.
