Hi,
I have an issue that seems to be simple, but somehow it does not work.
I want to give a car 4 wheels. (yes I know about wheelcollider, but that’s not good for me for some reason)
So I have a body, and 4 wheels. If I simply create a hinge for all the wheels, they rotate perfectly as I expect. However the two front wheels need to turn. For that, I add an intermediate object between the body and each of the front wheels. I break up the hinge between the body and the front wheels, but connect the wheels to the intermediate objects (let’s call them steerobj). Also I connect each of the two steerobjs to the body on the Y axis.
Now I have the following physics hierarchy: body → (y) steerobj → (x) wheel
From this moment, I can rotate the steerobjs around the axis Y, works perfectly, but the wheels stop rolling. I can see that the axis is screwed up when I run the scene, both the wheel and steerobj axes become parallel. Why? I tried out a tons of trick to turn them into the right direction, also I tried to add both the hinge joints to steerobjs (one connection to the body, and the other to the wheel), but it didn’t work. I tried out to give a collider to the steerobjs too, but nothing changed.
Also I tried out that everything works just fine if I connect the steerobj hinge to null (make it fixed to the static space). This way both the wheel and the steerobj can be rotated on the axis they have on their hinge. When I connect the steerobj hing back to the body, everything is wrong again.
Can you help me please? Any hints, workarounds… and of course a real solution would be much appreciated. Thank you.
Weke.
