Solution to CompSci 4, Test 2 - Fall 2006

1A. When the world starts
    When G is typed
    While Cow distance to horse1 > 3

1B. world.myfirstmethod
    horse1.Gallop
    turn to face - (cow turn to face horse1)
    move - (cow move forward 1 meter)
    world.greeting

1C. At the same time, the following things happen
       1. Chicken.JumpOnTopOf horse1  is executed
       2. BDE is true so cow turns to face horse1 and moves forward 1 meter
           repeatedly until it is <= 3 meters
           Then world.greeting is executed.

2. camel
   cat
   flamingo


3. Need a local variable to save the random value so it can be used twice
   Need to generate a random number from 2 to 4 integer only

   Revised code:

   123 randomValue = 0     // declare a local variable
   randomValue set value to random number minimum=2 maximum=4 integer only=true
   beachBall move up randomValue meters
   beachBall move down randomValue meters

4A. 50 meters
 B. 10 meters

5. while pterodactyl distance to scorpion >= 0.5 meters
        pterodactyl move forward .25 meters
        scorpion.waveClaw
   scorpion set vehicle to pterodactyl
   pterodactyl move up 6 meters


6. score.IncrementScoreNew

   if objectClickedOn == obj1
      score.value set value to (score.value + 2)
      score set text to (score.value as a string)
   else
      if objectClickedOn == obj2
          score.value set value to (score.value + 5)
          score set text to (score.value as a string)         
      else
          do nothing
    

7A. 123 world.HowManyOfThisColor  color color
  
    123 count = 1
    count set value to 0
    For all world.frogs, one item_from_frogs at a time
         if item_from_frogs.color == color
             count set value to (count + 1)
         else
            do nothing
    Return count


7B. 
world.moveBehindBar  color color
 For all world.frogs, every item_from_frogs together
    if item_from_frogs.color  == color
       item_from_frogs turn right 0.5 revolutions
       item_from_frogs move forward (item_from_frogs distance to balletBar +1)
    else
       Do nothing  


8A. 
obj world.firstshorterAnimal  obj someAnimal

  Loop 123 index from 0 up to but not including 6 times incrementing by 1
      if value at ArrayVisualization [index]'s height < someAnimal's height
         Return the value at ArrayVisualization [index]
      else
         Do Nothing
  Return someAnimal


8B.
123 world.indexOf  obj someAnimal
   
  Loop 123 index from 0 up to but not including 6 times incrementing by 1
      If someAnimal == the value at ArrayVisualization[index]
          return index
      else 
          Do nothing
  Return -1
