sooo.. now im gonna learn it a bit ;D
P.S.
The topic can be closed now

Thanks and you too ;D Ow, but an other question - what scripting language is it written in?

@EDIT
Because some of those Sketchy things are in Ruby.. but i think SketchyPhysics doesn't use it...

ow... thanks i didn't think about the motor joint

thank you guys for all the help - this forum users are really intelligent - the car works perfecto

i checked it... and yea it works, but in my model, i think that its something with wheels... check this:
Car

both don't work backward

well i used the hpnisse's script, now im trying yours

umm yea now i made a car (without steering, just forward and backward), but it doesn't move backward, only forward O.o A standard question: what is going on? xD

wow thx my friend xD

wow thx ur good
ow but i dont have an idea where to put

if key("Up")==1
  setVar("drive",1)
elsif key("Down")==1
  setVar("drive",-1)
else
  setVar("drive",0)
end

ok but how to make that up is forward and down is backward?

@EDIT
Because I made a car and when I press "up" the car doesn't move because wheels turn in other directions!
