From my last about the midterm until now, time for submission I had to change a few things. The biggest change was how the game would operate. Initially the plan was to have the shooter in the middle of the screen and have a pointer that would change location based on the location of the mouse in the window, however I changed this to have the shooter moving from side to side as a not to have the user/player switch between the mouse and the keyboard for now the player can play the entirely from the keyboard.
Objective of the game
Try to get as many points as possible while keeping the number of cases as low as possible within 2 minutes/
Game Operation
The keys used for the operation of the game are:
1,2,3,m, space bar and the left and right arrow keys.
The space bar will shoot the fighting tool that is currently selected, this can seen in the shooter icon. Keys 1,2 and 3 can be used to switch between the fighting tools when you’re in “fight” mode. Keys 1,2 and 3 can be used to buy more fighting tools when you are in buy mode. You can switch modes by pressing the m button.
The difference between the fighting tool is number of points you get when you shoot the virus down and the speed of the fighting tool.
Speed of Handwash < Speed of face mask < Speed of face shield.
Shooting the virus down with a handwash will get you 1 points, shooting it down with facemask will get you 3 points and the shield will get you 5 points.
You can use the points to buy more tools. Buying more handwash will cost 1 point, face masks cost 2 points/mask, and face shields cost 3 points/shield.
The number of cases will go up if the virus goes below the window.
