Question

inish the VPython code to move the ball to the left six units.
ball.pos.
= ball.pos.

Answer 1

You can decrease the x-coordinate by 6. For example:

ball.pos.x = ball.pos.x - 6

Or using shorthand:

ball.pos.x -= 6

Other equivalent ways:

ball.pos += vector(-6, 0, 0)
# or
ball.pos = ball.pos - vector(6, 0, 0)
