Draw.Oval (60, 50, 15, 15, black) 
Draw.Oval (200, 50, 15, 15, black) 
Draw.Line (90, 50, 170, 50, black) 
Draw.Line (230, 50, 250, 50, black) 
Draw.Line (250, 50, 250, 100, black) 
Draw.Line (250, 100, 220, 100, black) 
Draw.Line (220, 100, 170, 130, black) 
Draw.Line (170, 130, 70, 130, black) 
Draw.Line (70, 130, 40, 100, black) 
Draw.Line (40, 100, 10, 100, black) 
Draw.Line (10, 100, 10, 50, black) 
Draw.Line (10, 50, 30, 50, black) 
Draw.Fill (60, 50, blue, black) 
Draw.Fill (80, 50, black, black) 
Draw.Fill (200, 50, blue, black) 
Draw.Fill (220, 50, black, black) 
Draw.Line (170, 130, 170, 90, black) 
Draw.Line (170, 90, 120, 90, black) 
Draw.Line (120, 90, 120, 130, black)

Re: Can't make my car move

-----------------------------------

If you are trying to make something move in 2D space you need to somehow change the values of an object's 'X' and 'Y' coordinates.  You can start by adding the 'x' value from your loop to the x coordinate of your lines and ovals.  Just remember that the lines have two x values so you need to add it in two spots if you want to keep that length of the line constant.  

Here's an example

Draw.Oval (200 + x, 50, 15, 15, black)
Draw.Line (90 + x, 50, 170 + x, 50, black)
