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 192 to 202 of the apjavaProcessing slide presentation and the Math.random worksheet helpful. Here are some steps to get you started:

1. Start by forking this repository.
2. Open the Lightning.pde file. You'll need to add some code At the top of the program, declare 4 int variables startX, startY, endX and endY. Initialize startX to 0, startY to 150, endX to 0 and endY to 150
3. void setup() needs to set the strokeWeight() and background() of your applet
4. 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
5. void mousePressed() needs to set startX,startY,endX,endY back to their original values.
6. You will 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
7. 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

Your program needs to create a random walk using 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!
