I'm using the PH_WHEEL-constraint for a car simulation. It works quite fine but sometimes when I steer from one side to the other (I used the steering techique of the car-example) the depending wheels wobble (spin around ignoring the set restrictions) from time to time. Also the car-example included in the Gamestudio installation has this problem - try to steer a few times from fully left to fully right and so on ...
What's the problem??

Thx in advance!

Hi, I had the same problem before!

Don't use real Values for the weights of wheels and so on...
Better use some smaller weights!

f.e.:
i use 7 for the car-body and 12 for each wheel!

I already have the wheels at 1 and the body at 3 - is that few enough?

When talking bout WEIGHT you mean MASS, right?

BTW.: Your wheels are heavier than the body??

sry yes, i mean MASS !

i think thats few enought!
But perhaps try to change, so the wheels have 3 and the body 1 units of mass...

Good idea! I will try that! Maybe that stabilizes the rotation because of the therefore hightened torque of the rotation. In reality it would ;-)

Cheers, Chrisu.

I still have that problem. Even if using light weight mass the problem persists.
Is there any physics engine update to avoid that?
It is a very bad effect!

Jcl, is there any way to solve this problem? Basically physics engine built-in 3DGS is good (even if not perfect...) and easy to be used.
But I think you need to improve a little bit small but important iteams like this.

Thank you.

No official answer about physics engine...

Is there a way to solve this problem?
If not I´ll make a bug post at monday.

I couldn't find one yet.
