DifficultyPicker automatically varies the difficulty of the game

Use DifficultyPicker to set up automatic difficulty adjustments for your game.

p = new DifficultyPicker 1, 50
onRoundStart ->
  write p.pick()

You need two things to make a DifficultyPicker work in your game:

• new DifficultyPicker defines a new picker, and tells it what the easiest and hardest numbers will be. The numbers it picks will always be between the easiest and hardest you specified.
• something.pick() actually picks a difficulty level. This should usually happen inside onRoundStart, since you usually want to adjust difficulty at the beginning of each round.

How it works

Here are the nitty gritty details about how the DifficultyPicker chooses numbers:

• Whenever you ask the DifficultyPicker to pick(), it selects a new number between the easiest and hardest numbers you gave it during set-up.
  • it only picks a new number once each round. if you ask it again within the same round, it will keep picking the same number.
• The first three rounds, the DifficultyPicker picks the easiest number, and sees how long it takes the dog to solve the game on the easiest setting. This is the baseline time
• For each round after the third one, if the dog solved the previous round faster than the baseline, the DifficultyPicker picks moves the difficulty toward the hardest number. If the dog solved it slower than the baseline, it moves it toward the easiest number.
• Each DifficultyPicker works independently: if you have more than one, they won't know about each other.
