Rolling Resistance for Reverse Operation #4

Closed k4kfh closed 8 years ago

k4kfh commented 8 years ago

Rolling resistance remains negative even when operating in reverse. This should not be; it should change to positive with motive force being negative during reverse operation.

k4kfh commented 8 years ago

The primary issue here was a lack of setting sim.direction. Rolling resistance is multiplied by sim.direction, so if done properly when in reverse that means rolling resistance is multiplied by -1, making it a positive number since a retarding force is already a negative by default.

With some testing, I have confirmed that the above commit fixes this issue.
