Question

Process:

In this lab, you will be implementing a simple “Bop-it!”-like game. Your program will run for a single game. Start with implementing a “start menu”, output a line asking the user to push a keyboard key to start and wait for the user to push a key.

The game will involve printing a line telling the user which key to press (chosen randomly by the program) and will wait a certain time for a response. After each successful action by the player the time the program will wait for a response will reduce. The game ends when the player does the wrong action or time runs out, (finding time passed may not be as easy as you think, hint: you may want to keep track of a previous time value and compare that to the newly scanned-in time).

Note: You should ensure that key presses are only registered once per press.

Requirements

• Program prints a message telling the user to push a key to start the game.
• Once in game, output tells the player which key to push. The key to press should be determined randomly.
• Part 1:
  • Game runs continuously until the user reaches a loose condition.
    • A wrong key is pressed
• Part 2:
  • Continuing on part 1, but instead of asking the user to push a certain key, print an ASCII table from A-z, and tell the user to press a certain ASCII value
  • For example, “push 97” **wait till a is pressed.
  • Make sure to layer the ASCII table nicely
• Program waits for user action for less time after each iteration.
• Program outputs how many successful actions the player executed at the end.

Questions:

1. How did you randomize the keys that needed to be pressed?
2. What game states, if any, did you keep track of?
3. What mechanism did you use to make sure extraneous key presses were not registered?

Answer 1

1. Randomizing the keys that need to be pressed.

Answer. I would just generate a random number between 33 and 126. Then every couple of char's randomly add a 32. 32 is a space. 65 - 90 are upper case, and 97-122 are lower case.

code to generate a Random number:

Random randomGenerator = new Random();
int ran = randomGenerator.nextInt(126 - 33);
ran += 33;

Then ran would be your random character. You could have a loop and do that a couple of times.

You don't even need to use KeyEvent.VK_SPACE. You will get a return of "32". That corresponds to the ASCII chart, just use that If you use:

System.out.println(KeyEvent.VK_SPACE);

2. The Game states that needs to be saved are Following:

• Starting of game
• Time out
• track of a previous time value and compare that to the newly scanned-in time
• key presses are only registered once per press
• successful actions the player executed at the end.
• Ending of game

3. mechanism used to make sure extraneous key presses were not registered is that we can simply store the extraneous keys in an array and put a condition on the key entered is that if it got the keys which belongs to this array pops a message that "extraneous key entered" if not then it can simply allow to press the key.
