Version 2.0 is here! (Updated 1/4/00)
Added to version 2: Keyboard input is now enabled. The direction of the fields are indicated at the top of the screen. The New Player and the Charge to Mass buttons were deleted.Object of the Game:
The object of the game is to hit the rectangular target at the top of the screen by manipulating the electric and magnetic fields.
How to play:
Click on the Start button to start the game. A positively charged ball, represented by a blue circle, will appear at the bottom of the screen. You can then change the magnetic and electric fields using the + or - buttons or by using the keyboard controls. The direction of the fields are indicated at the top of the screen. The game is over when the charge hits any side of the screen.
Scoring:
The score is calculated using the distance from the center of the target to the upper left corner of the charge. The score is a function of the inverse of this distance (1/r).
Keyboard controls:
I strongly recommend that you use the keyboard to change the fields, rather than using the plus/minus buttons.
Key Property q increases the magnetic field by 1 a sets the magnetic field to 0 z decreases the magnetic field by 1 p increases the electric field by 1 l sets the electric field to 0 , (comma) decreases the electric field by 1
