Comp152 Project 5: Graphics and Games

Objectives:

• Write a larger/more significant project than you have so far: providing a fitting capstone for your cs1/cs2 experience
• Work with Graphics
• Work with keyboard and mouse inputs/events
• Practice with linear collections
• practice nearly all of the techniques and cs concepts that you have learned over the last two semesters.

Details:

• You must have a ship which represents the player
• the players ship must move back and forth horizontally just above the information area of the window (see below)
  
• the player ship must respond to mouse or keyboard  events to control the movement. 
• if the player ship collides with any enemies or with an enemy shot it is destroyed and the player loses one ship (one life)
• when the player loses a ship, the game should continue with the next ship if the player has any more ships (lives) left.
  
• A player ship can fire a shot (see shots below) no more than once every 100 milliseconds.
• A player that is out of energy (see below) dies (lose a ship/life)
• if you use keyboard navigation then respond to the arrow keys as I'm left handed. (WSAD doesn't work for me)
• You must have energy for the ship.
• you need an energy bar to represent the remaining energy. You should start out with 1000 energy
• Each shot should take 40 energy.
• Each enemy hit should return 20 energy to the ship
• You must have 20 moving enemies that work like the hamburgers in the first level of megamania. (the hamburgers)
• these enemies can be any image you want so long as they are not used elsewhere in the program, have a transparent background, and are appropriate for classroom use.
• The enemies must be in three rows with alternating locations like in the hamburger level.
• The enemies must move horizontally across the screen - exiting from the right hand of the screen and reentering on the left.
• The enemies must shoot occasionally. One enemy should shoot every 1-5 seconds. (accomplish that how you like)
• You must have a way of letting the player ship shoot.
• the shot should use energy as detailed above.
• if a shot hits an enemy, then the shot and the enemy should disappear.
• the ship should also regain 20 energy when the shop collides with the enemy.
• The players score should go up by 40 when the enemy is destroyed.
• if a shot hits an enemy shot, both shots should disappear.
• Your player has three extra ships/ lives at the start of the game
• represent this in your game somewhere so the player can see how many ships the player has remaining.
• Each time the players ship 'dies' (collides with an enemy or hit by an enemy shot)
• if there is a remaining ship, the player should have a new ship appear about a second later. It should be invulnerable to shots for another second.
• this uses up one of the lives.
• when the last ship/life dies, the game should end.
• when the game ends this way, stop the game and show the user his/her score and tell them he/she has lost
• If the player destroys all of the enemies then
• move to a second level, repeat the first with a different image and a different movement pattern
• for every remaining energy point remaining, add one to the players score.
• score
• display the players score somewhere that the player can see.
• For every thousand points that the player scores, the player gets an extra life.
• Winning
• if the player clears the entire second level, the player wins the game.
• stop the game and display the players score and a message about the player winning.

I anticipate that this project will be worth about 260 points. That should put the following extra credit possibilities in context. In order to get extra credit, you must finish the main program above before doing the extra credit. For extra credit you may do any of all of the following.

• For 30 points: add  the following sounds to your game.
• Have a sound for firing,
• a sound to begin the round
• a sound when an enemy is destroyed
• a sound when the players ship is destroyed
• a sound for winning
• a sound for losing the game
• For 25 points 
• add another level with a third type of enemy and a third type of enemy movement.
• For 15 extra points 
• When the game is over there should be a way to restart the game without restarting the program.
  

Extra Requirements:

You must satisfy the following constraints on your program

• Your program should be well commented

• No one method may be longer than 25 lines  of code long (Lines with only braces on them don't count. Since comments and white space aren't code, they do not count either.)

• Make sure each of your classes represents only a single concept. You will need classes for at least the player ship, the enemies and the game, and probably more than that.
  

Submitting:

When your program is ready, you need to write a readme.txt file that provides me the following information:

• Your name

• The name of your java files (and the names of any extra non-public classes that are contained in the file.

• The implementation decisions that you made. Why did you solve the problem the way that you did?

• Did you implement any extra credit? if so what?
  

• Directions on running and using your program. Especially anything that might not be the same for all students. Give me directions for running your game. How do I control the ship? how do I fire?
  

• And any problems or bugs left in your program. If your program doesn't quite work in some situations, tell me about it. If your program doesn't run or compile, I want to know that before I try.
