You need to fix your links, they don’t lead to the images that you are reffering to.
There is a problem in your python script. Write the code exactly as I write it in the tutorial, including spaces. Your if statements should look exactly like this: (note the spaces between = and -speed and -rspeed)
To learn more about python in general you should go through the 3rd prerequisite link, and read “A Byte of Python”.
walk = speed
walk = -speed
turn = rspeed
turn = -rspeed
You should ask questions like theese in the Game Engine forum, where I can see them and answer them.
Also, there are no = signs after getSensor. It’s just cont.getSensor(“sensorname”). And yes, you need cont everytime before .getSensor().
You really rushed it.
