[Vtec234]

[Vtec234]

both don't work backward

[hpnisse]

I've got both work correct both forward and backwards.

Download and look this model.
hpnisse vs hobbnob.skp

I don't know what you did but here I got both working with the up/down arrowkeys at same time.

Hope this helps understanding!

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

[hpnisse]

You use servo as motor, I changed it so all servo is the "motor" joint insted. and it work perfect.
Then I use my script and changed some stuffs so it would be easy to change the speed.
Samochód.skp

To change the speed of the wheels then change the number "3" in the "Speed" box.

if frame==1
setVar("speed",3)
end

then it will work fine.

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

[hpnisse]

Good that your happy.
Have a nice summer!

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...

[hpnisse]

It should be in ruby I think.
http://sketchyphysics.wikia.com/wiki/Ruby
It says that Ruby is used to control SketchupPhysics so I think SP would be written in that script.
