Animation with setup() and draw()

• • Here’s a program I wrote to continuously draw points in a random place

void setup()

{

size(400,400);

strokeWeight(4);

}

void draw()

{

point (random(400),random(400));

}

• The commands between the { and the } below setup() are only performed once, when the program first starts.

• The commands between the { and the } below draw() are repeatedly executed, a few times a second.

• change the program to draw lines in random places

• use frameRate() to change the update speed (you can read about this function in the Help/Reference section).
