Just like we were following a path in the last challenge, this one has a wrinkle in it – angled turns.
We’ve got built in commands for turns with pre-prepared settings for 90° turns.
So what do we do if we have a 45° turn?
How about dividing the 90° turn setting in half – because half of 90 is 45!
hardTurn90 / 2
How about a 30° turn? Divide our 90° value by three!
hardTurn90 / 3
How would you do an about-turn – that’s 180°. You could add two 90° values together.
hardTurn90 + hardTurn90
This way, you can build up a whole range of turns which would allow you to follow paths like this:
Using the power of math, you can figure out any angle you need – just divide the 90° value by 90 and then multiply by the angle you need, like this:
hardTurn90 / 90 * degreesYouWantToTurnHere
so if you need to turn by 25, the calculation would be:
hardTurn90 / 90 * 25
You may want to get a protractor to help with angle measuring.
