This look like it should not move but does, requires you copy the road2.png to the same folder you save this code too.(this is one of the demo codes modified )Vehicle is not great.

Got off to a good start with it

How are you finding the vehicle section of Dark Physics so far?

Well that was just an attempt at seeing if I could get my own DBO model going with it, which as you can see I did, will be trying more as the week goes on.

Ps. Do you find your Tea and Coffee

keeps going cold!, even the games I have brought lately have not manage that.

Hint for those making your models, work backward on them.

eg: I started with the wheels size, height and lenght, then double the sizies where needed to fit.

in the above code the wheel size is set at 0.6 so I make the object sphere 1.2.

Have I got my so call wheels placed it the right order, as what I expect is not what I see happening.

the rotation of the object is oppsite to what way they should turn.

I put cones for wheels but they rotate into the vehicle rather than along it.

EDIT: I guess the below is not right. They are on opposite sides
and need to turn opposite from each other. Seems strange.

Shouldn't the last number in the phy add wheel command be the same
for each wheel set? You have both front wheels turning in different
directions. Your vehicle works good, though. doesn't seem to make
any difference

Why does rotating the Y direction make my object rotate in the X direction?

You need to add the rear wheels first and then the front wheels.

When the wheels are updated they are rotated on the X axis to make them spin and on the Y axis to steer. Will look into providing some more information on how all of this works.
