Wheels, motor joint and downhills/uphills [message #3465]

To start, my biggest compliments for such an embarassing great project as Nape..

Then, my problem is about a prototype of a bike/car game i'm doing, side scrolling.
I did use a motorjoint on the back wheel , with a rate that i multiply on every tick for a damping.
It works quite fine but of course if i don't thrust it when in downhills it stops (or when in uphill, it won't accelerate backwards, as you want to see it Smile

)
What i'd like is to add some inertia to the motor force, so that if it's low the ground shape conformation overcomes it.
How would you do that?

TIA

Have you tried decreasing the rate to 0 when you're not thrusting?

You probably want to set the maxForce property of the motorjoint which would be more realistic and would also give you 'engine braking' when you're not pressing the accelerator. Essentially what you have now with maxForce = infinity (default) is engine braking that is so powerful you instantly stop.

I created nape!

Woah i just found this answer after ages! the project got frozen and well..
Anyway, i tried playing with maxForce values and it works BUT it now seem to ignore my rate setting Neutral
