Lightning

One way to simulate lightning is with a random walk. In this assignment you will create a program that uses a random walk to seemingly shoot lightning from one side of the screen to the other every time the mouse is pressed. You may find sides 16 to 40 of the apjavaProcessing slide presentation helpful.

Suggested steps to start the assignment

1. Sign up for a free GitHub account
2. Then fork this repository
3. Open the Lightning.pde file. Copy and paste the code into Processing.
4. At the top of the program in Processing, declare 4 int variables startX, startY, endX and endY. Initialize startX to 0, startY to 150, endX to 0 and endY to 150
5. void setup() needs to set the size(), strokeWeight() and background() of your program
6. void draw() needs to do two things:
   -set the stroke()color of the lightning bolt to some random value using Math.random()
   -a while loop that repeats the following until the endX is off the screen:
   1. set endX to startX plus a random integer from 0 to 9
   2. set endY to startY plus a random integer from -9 to 9
   3. draw a line() with endpoints startX,startY,endX,endY
   4. set startX equal to endX
   5. set startY equal to endY
7. void mousePressed() needs to set startX,startY,endX,endY back to their original values.
8. When you are happy with the program, copy and paste it back into GitHub
9. You will also need to modify index.html to customize your website with it's own title, headline and footer. When you are happy with your program, push your finished project up to GitHub
10. The final step is to submit the URL for your website to google classroom. Don't hesitate to ask for help if your aren't sure how something is suppose to work.

Program requirements

The steps above are only a suggestion. Your program needs to use Math.random() for all random numbers in the assignment. Other than that, your lightning program doesn't have to work or look like any other. Have fun and be creative!

GitHub problems?

If your program works in Processing but not on GitHub, check this list for possible solutions. If your program still isn't working on GitHub let your instructor know.
