Example Questions
Exam 1

Consider the screen shot given below. Assume that the text cast member is named “score” the button is named “play”, and the second text cast member is named “name”. Give scripts to create the following interaction:

1. What property of the sprite 3 (the “name” cast member) must you change to make this movie work and how must you change it?

When you click on the button, you must generate a random number. Put the die that corresponds to the number on the stage. Play the sound “electronic bong”.

2. If the result was a 4 or a 6, put “Name, you win! Number of tries is X” into the “score” field. Name should be whatever is in the “name” field and X should be the number of times that the “play” button was clicked since the movie was started.
3. If the result was a 1 or a 3 put “Name, pay double! Number of tries is X” into the “score” field. Name should be whatever is in the “name” field and X should be the number of times that the “play” button was clicked since the movie was started.
4. If the score was 2 or 5, put “Name, you lose! Number of tries is X” into the “score field . Name should be whatever is in the “name” field and X should be the number of times that the “play” button was clicked since the movie was started.
5. Loop through this animation so that I can continue to play your game.
6. There should be a Halt button in all the frames of this animation. If I click on this button, the movie should halt but not quit. In other words, director should still be running even though the movie halts.
7. When the movie begins, the score must be 0 and the “score” field must display a message such as no score, and the name field must say “no one”. Where must this script be put? Write the script out.

Solution: put the following script in the play button:

	on mouseUp me
  global theScore
  
  theScore = theScore + 1
  
  theRoll = random(6)
  sound(1).play(member("electronic bong"))
  
  
  sprite(1).castNum = 35 + theRoll
  if theRoll = 4 or theRoll = 6 then
    member("score").text = member("name").text & ", you win!  Number of tries is" && theScore
  else
    if theRoll = 1 or theRoll = 3 then
      member("score").text = member("name").text & ", pay double!  Number of tries is" && theScore
    else
      member("score").text = member("name").text & ", You lose!   Number of tries is" && theScore      
    end if
  end if
end
