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:
- Start by forking this repository.
- Open the Lightning.pde file. You'll need to add some code
At the top of the program, declare 4
int
variablesstartX
,startY
,endX
andendY
. InitializestartX
to 0,startY
to 150,endX
to 0 andendY
to 150 void setup()
needs to set thestrokeWeight()
andbackground()
of your appletvoid draw()
needs to do two things:
-set thestroke()
color of the lightning bolt to some random value usingMath.random()
-awhile
loop that repeats the following until theendX
is off the screen:- set
endX
tostartX
plus a random integer from 0 to 9 - set
endY
tostartY
plus a random integer from -9 to 9 - draw a
line()
with endpointsstartX
,startY
,endX
,endY
- set
startX
equal toendX
- set
startY
equal toendY
- set
void mousePressed()
needs to setstartX
,startY
,endX
,endY
back to their original values.- 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 - 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.
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!
