Default [Help] Wire Wheels

Ok, this is going to sound like a stupid question - but how do I brake with wiremod wheels?

I see theres an input for 'speedmod' and 'brake' and I've tried various different values to no avail.

Second question, anyone got any idea how I might wire up a traction control to the wheels? I've tried decreasing the force limit, but that means it starts slowly then suddenly start spinning way to fast and the car lurches forward and slides when you try to turn.

I was looking at producing some kinda of speed multiplier from the division of the radial velocity of the wheels and velocity of the entire car. Of course it would need some offsets to stop it doing stupid things at fullspeed and at a stop.

I don't do expressions or CPUs unfortunately, just lots of logic gates. I'm not a complete wirenub, I just stick to what I know - and since I study Electronic Engineering and have done plenty of Boolean Alegrba and Digital Design. I tend to avoid programming and go for the real gates.

Also, I find it hard to find decent servers to join. I need one with friendly English speaking people who might help me when I get stuck.

Any help would be greatly appreciated,

Higher value to the brake input the more brakes applied. However, pass a certain value like 30-50 and the wheels will start to slide slowly and the car will not stand totaly still.

Traction controll... hmm. I made an anti-spin system by using a gyro on every wheel and hooked deltas to them(Good drive and good steering on super ice material). Then you have to increase the max allowed deltas, on the fly, to compensate for the acceleration.

I tried brake values of 1, -1, 0, 200, -200, 0.00001 - strange I never thought of 30.

Anyways, cheers.

I like the sound of the anti-spin system. Possibly the permissible delta could go into a function with overall speed to allow more acceleration when already moving fast. But anyways, how did you feed the speed reduction to the wheels? Just use brakes when
x > z etc?

And did you do an individual system for each wheel?

No probs. Its was a while ago...sorry. But I did have a system for each wheel and rubber material on the wheels.

I cant remember the factors between the speed(of the car) and the delta on the wheels. Just try different values. I belive its somewhere 10th-100th of the speed from the speedometer(standard value).
