Authors: Joshua Berman , Terry Bugai Date: Sunday, September 15, 2013 19:40:40 PM Message: Version 1.0 with unit-tests. spaceship moves from right to left added functionality of spaceship moving up and down using arrow keys. Version 1.1 with unit-tests. enemy ships (Brains) put in place. tests: testing for change in coordinates with ship movement. Version 1.2 with ship fires projectile. brains fire projectiles (neurons). tests: test for brain projectiles firing correctly. Version 1.3 with space ship gets destroyed when colliding with enemy ship or enemy projectile Version 1.4 with "brain freeze" and "brain fire" enemy ships implemented. Some brain-freeze ships set to arc across screen and return to formation if no collision detected. Function for enemy ship dive bombing is also implemented.(enemy returns to formation correctly). Version 1.5 with Enemy ships set to move right and left (correction to distance moved must be attended to). Version 1.6 with PowerUp class implemented. allows the SpaceShip to increase weapon damage by changing to more powerful weapons randomly. Version 1.7 with "shock Therapy" weapon added - kills up to 3 apponents at a time. "Virus" projectile added - 'infects' all enemies in a column. Version 1.8 with "Bubble Shield" added. Spaceship is not effected by enemy projectiles when shield is in place. "Wrap Around" powerUp added. allows spaceships to wrap around the screen to evade projectiles. Version 1.9 with Display class implemented. Used for idications, scoring and general string displays. Game over indicator when ship is destroyed. spaceship blows up on impact. Version 2.0 with unit-tests. PowerUp selection is done by collecting a sphere moving across the screen. stop watch class implemented in order to control better timing and assist with brain movement. tests: test that powerups operate correctly. (Wraparound,virus,shock,shield). test that all game states call correct functions. Version 2.0.1 with unit-tests Scoring system implemented. display functionality added for game status and powerUps. fixed brain movement. fixed brain collision when diving. test scoring system test positions get and set. test various collisions. test game over and game win.
