What will this script do?
Turn a sprite right 15 degrees when Y is pressed
Turn a sprite left 15 degrees when Y is pressed

What is wrong with the car for our game?
It is too small
It is too green
it is too big
It needs to be seen from bird's eye/top plan view
Why is this car suitable for our game?

Repeat moving 1 step 10 times
Repeat moving 10 steps 1 time

Why do programmers use repeat or forever loops?
To save disk space - the program you create will be smaller
So you have a choice about what you want the program to do
To save time - you don't have to keep re-writing the same code
See the line of code can be executed in a sequence
What's the difference between a "repeat" and a "forever" loop?
The repeats, the other one loops
A "forever loop" loops a number of times, "repeat loops" loop until the red flag is clicked
One takes longer than the other
