Problems with vehicle model

Hey guys

I've been wrestling with the new NF med tank for a while, it's floating off the ground and is very back-heavy which makes it do wheelies all the time and unable to steer.
Any idea what could be the problem here? All the .qc files are basically from the BE medium that i hacked together with my own stuff.

 

While the off center weight might seem like a odd and cool thing, i wonder if it wouldnt complicate the steering even more, maybe even break how tanks react to mines. Woudlnt really want to have meds flip to 3 mines.

 

The (invisible) physics wheels are probably set wrong. That's probably why it's floating.

Hit me up on steam and we'll clean it up. It'll probably take a few recompiles, but it's not hard, just tedious.

Oh and you're a wonderful human being for doing this. Like really.

 

The leaning back... seems like it might be from the BE afv. The AFV has larger front wheel and smaller wheels for the tracks. You might try looking in the vehicle script itself. look at "radius" to make sure they are all the same.

You will also get that if the springs are not all set the same.

One more thing... omg... please keep it down to 3 axles at the most. No need to make steering a serious pain in the ass.

 

Yeah, it just needs some wheel-love.



Yay, I get to feel important!

 

spart... why is that tank... grey?

 

I don't know, but I'll probably figure it out. Or someone else will. That's not my concern at this point.

 

I fucked around with trying to replace the AFV at some point, and I gave up just because of this.

I believe there is a great deal of magic involved in making the vehicles behave, either in scripts or code, but something somewhere is overriding any physics models you compile with.

 

Yeah, I really need to at least put my existing work with this thing on the forums. Ship or die!

You can fix this, it's just mind-numbingly boring to figure out which fucking wheel mount maps to which other wheel since redskull unknowingly tried to put 10 axles on the tank.

 

Would it be easier if the wheels are set up like this? I have no idea what defines the amount of axles on a model.

 

The model that is visible doesn't matter (i think). It's all about how it's rigged, or how it's offset in the qc. Grrr, I keep putting this off.

 

yes its all about rigging not what the model looks like. The Model could be a flying saucer but, the rigging could have 4 wheels.

 

It only matters, if you want the road wheels to fit to the underlying terrain. Otherwise it doesn't matter.

 

So how would I rig this model to have fewer axles? Each wheel has a unique bone but I still don't know what determines an axle in the rig.

 

talk to spart about that. I didn't bother with rigging like spart did.

 

One thing that would make it much easier to work with would be to know which axle number maps to which visual axle. There are ten of the damn things and the physics wheels seem to be mapping to the axles at random (except for the front axle, which is just defaulting to the origin in the lower middle of the model).

You can see there's a wheel attachment point where every visual wheel goes.



Avoiding that "tipping" issue in the OP is actually really simple to solve. It's caused by the front wheels not having an attachment point (for reasons I can't figure out) and defaulting to the origin, which happens to be in the lower middle of the model, which "tips" it.

But even without the front wheels, we have 3 more axles to work with, which is plenty. We could make do with two if necessary. The fucking insane part of it is figuring out which vehicle physics axle.

You can see them below. They are the green spheres (wheels are spherical in Source). There are only three axles because the fourth (erm, "first"?) is stuck under the tank at the origin, but it's tiny and basically vestigial.

Note that the two that are touching the ground are higher than their attachment points because of the suspension. That's expected behavior.

Also note that the front is clipping through the ground because there's no wheel up there. That's easy to fix. It's intentionally not fixed because I wanted to use the original wheel points so Redskull & Friends could see where the wheels are spawning by default.



And the qc so far. I was going to just figure it out via manually recompiling with and without each axle (and apparently figured out one of them), but I lost my patience the last time I worked on this.

Isn't that something Redskull should be able to tell you? I mean from what I know those attachments are placed corresponding to bones. So you just need to know where which bone is.
