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

hpnisse

Somewhere in the model, just create a static box or something and put this (and the steering script) in the "ontick" field!

Then it will work

Vtec234

wow thx my friend xD

hobbnob

same thing as hpinsse's script, just all in one place:

setVar("drive",-(0.5-righty))

both do exactly the same thing, just that's shorter.

Vtec234

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

hobbnob

what scripts did you use?

Vtec234

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

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.

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

hpnisse

Good that your happy.
Have a nice summer!

Vtec234

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.

sooo.. now im gonna learn it a bit ;D
