wheelchair's wheels code

#1 try something like this

datablock WheeledVehicleTire(FLWheelchairTire)

   shapeFile =  "art/shapes/vehicles/parts/Wheelchair/Wheelchair_front_tire.dts";
   mass = 20;

   rollingResist = 0.2;

   // Spring that generates lateral tire forces

   // Spring that generates longitudinal tire forces
   longitudinalForce = 18000;

#2 thanks man for the code. Do I need to change any other file

#3 @Noah,
I have an idea that I want to run past you concerning wheel chairs. Here is my email: ***********************

#4 The way I see this happening is to make a new class for wheelchairs.
The front wheels are similar to a car but they rotate 360 degrees in two directions. The rear wheels work similar to a car but also similar to tank tracks. A wheelchair will also be slightly different in how it handles uneven ground and bumps such as a curb or a pothole. Acceleration and braking is also different.

#5 Can I e-mail you the wheelchair. E-mail me at noah.gomes2@gmail.com
