Driving simulation

Apologies for delay in response. I found that the issue was link.reset(viz.RESET_OPERATORS), which apparently undoes preMultLinkable. Our research is just about done for the season. Thank you Jeff for all your help.

Hi Jeff,

I've taken over the project from miles for this summer. Thanks for your help so far. We've almost got the entire rig working, but another problem has presented itself.

The code you provided in your last post was exactly what we needed. However, the car isn't turning properly. It's more or less drifting; when the steering wheel is turned, the car will turn in the right direction, but it will move both forward and to the side. Our code for moving the car is as follows:

self.car.setPosition([0,0,self.speed*viz.elapsed()],viz.REL_LOCAL)
self.car.setEuler([rot*self.speed*self.turn_speed*viz.elapsed(),0,0],viz.REL_LOCAL)

The head-tracking orientation data seems to be interfering with the local Z-axis of the car, though the local rotation is unaffected. I'm not sure whether to address the problem by making changes to the link or by making changes to the car movement. Any suggestions?
