Car setup help!

[Yfrid]

As usually i'm suddenly disappeared, to come back after months

meanwhile i've stopped also to mess in carma stuffs, but in those days i've resumed my first car attempt, i mean this one:

http://img139.imageshack.us/img139/2712 ... hedxk5.jpg

now FINALLY it's almost done, just needs internals textures, and a main just-yellow bodywork one.

i was wondering to try the car in-game even if incomplete, i've imported the model in PT2 by BeMax but i've not figured out how to setup wheels, i've already called them FRWHEEL etc.. from milkshape, same when converted to PT2, but when i try to setup a wheel he says "missing wheel actor!"



i've tried to follow the tutorial in BeMax, i've noticed that his menu is different, he goes in

Tools>Carma2>setup wheels

mine is

Object>setup wheels

[coffeycup]

Umm, you need to put the .ACT extension on the wheel names --> FRWHEEL.ACT

That is why it says it can't find any wheel ACTors.

Select the object and from the menu pick Object >> Rename

[Yfrid]

[coffeycup]

Are you setting all four wheels before hitting done?

You need to go through all four wheels in the pulldown menu,

checking steerable for the 2 front wheels. And then hit 'Done'

That's how I do it and it works everytime.

Otherwise I don't know why you get an error.

[Yfrid]

Yeehaww!

Now it works



I suppose that a file (maybe DAT one) got converted bad form 3ds to Carma2, or maybe a writing error by PT2 when i've saved the first time. In first place that actors thing, then after some attempts i've closed and opened again PT2 and a Wheel was disappeared! in the object list it was still there, but it was assigned to an other wheel so there was 2 different objects in the same one! WTF!? i've tried to rename objects hexing the DAT file, but i've just broken it..

after hours of pain i've just converted again the 3ds to carma2 and everything worked fine

the only weird thing (after wrong proportion) is that sm. groups got messed ingame, but on PT2 are ok, i guess that when Milkshape exported in 3DS had unjointed parts of many shapes :\

[The_Bollocks]

Cool! Nice one.

[timmy76]

i had the same thing but with a map tester i done a while ago said error when grouping it into a map, thought wt the hell tried it in game an dit worked was really pleased

not much :P

[coffeycup]

You're welcome.

[neitron]

Wow, that's nice! I like it!

[Yfrid]

Thanks guys

right now i'm spending some time to study how .txt and .wam stuffs works

i'm learning some crushable stuffs, like detach bodyparts and make the driver uncrushable



but i've not catched how to setup doors (for hoods)

i've tried also to mess on grooves. in the way of copy/paste-from-an-other-car-and-see-what-happens.

i've tried to make the driver's head to rotate calling the head TESTA.ACT and copy the groove from others but nothing happens

tried the same on suspensions wich animate, but in a totally crazy way and i've not understood how values works

[coffeycup]

Umm, did you try searching? Its not like we've never talked about doors before here.

http://www.cwaboard.com/ubbthreads/show ... #Post46940

There' tutorials on my site for suspension setup

[Yfrid]

Ok, yesterday i've setup everything i was able to do:

Smashables, Flapping Doors, moving head, correct suspensions animation, scrubs coordinates, moved pivots rotation point, need to do mess few other stuffs.



Now, i'm messing on B.Boxes, and i've got a question. i've searched around and found this tip:

----------------------------------------------------------------------------------------

Bounding shapes

This shape definition is used for all collisions in the game.

It is important to get this shape to fit your car as

close as possible. It will add a lot of realism to your car. If you are adding a lot

of suspension, remember to raise this shape as needed. - CarEd Tutorial



You need to edit the coords for the BB in your car's TXT file:

EXAMPLE ONLY

1 // Number of 'Bounding shapes' entries.

polyhedron // Type

8

-0.190,0.050,-0.384 // L B F (left bottom front)

0.190,0.050,-0.384 // R B F (right bottom front)

0.190,0.1504,-0.384 // R T F (right top front)

-0.190,0.1504,-0.384 // L T F (left top front)

-0.190,0.050, 0.3659 // L B R (left bottom rear)

0.190,0.050, 0.3659 // R B R (right bottom rear)

0.2169,0.2170, 0.4018 // R T R (right top rear)

-0.208,0.2170, 0.4018 // L T R (left top rear)

------------------------------------------------------------------------------------

In this example, is explained the vertex order but is a simple box.

My question is: how it's supposed to be the vertex order on more complex shapes?

and, is this shape good as a b.box?



this model is composed of 3 objects: 2 boxes for wheels and a bit more complex one for main body.

[coffeycup]

Just use 3 BBoxes for yours, it'd be something like

EXAMPLE ONLY

3 // Number of 'Bounding shapes' entries.

Thanks coffey

i've tried these coords, but C2 crashes in the loadscreen without any error °_°

[coffeycup]

I don't know. That looks like its set up right.

do you have this at the end of your code?:

0 // Number of sub-parts.

END OF MECHANICS STUFF



Otherwise I'd just try one shape at a time to see if its just one thats bad.

What I don't understand is the x axis numbers on the 8 sided box for the wheels.

usually the left side number is a negative of the the right side. you have

-0.175 ,0.022,-0.232 // L B F (left bottom front)

0.121 ,0.022,-0.232 // R B F (right bottom front)

-0.175 and 0.121. Is your model not centered?

[Yfrid]

yep, model is not centered :\

in milkshape it was centered, but facing in the opposite side. So i've just rotated it right for C2, then exported in .3ds but accidentally i've rotated around "center of mass" instead of "origin", and the result was that offset on x axis. Only after a while messing on coordinates in car's.txt i've noticed it wasn't centered.

Already tried to use B.boxes separately, even tested on other cars, but same result

[TTR]

Try this, all the bottom coords should have the same height, so make them all the same..?



Shit..i actually posted..heh..

[Yfrid]

now it works!

I've splitted the main shape in 2 boxes. After that, C2 was crashing anyway but this time appeared the error "wheels outside all shapes". Then i've noticed that FRWHEEL was in a stupid position: "-0.412" instead of "-0.142" on x coords.

The old b.box won't work anyway, but this one looks good enough

Last step, finish texturing
