Drop

Drop[] drops = new Drop[100] ; //this is an array for making 100 drops to fall to make more increase the number

void setup(){
size(640, 360); //size of the screen
for (int i= 0; i < drops.length; i++) { // creating a loop to add 100 drops into the array
drops[i] = new Drop();
}
}

void draw() {
background(0); //color of the screen
for (int i = 0; i < drops.length; i++) { //creating a loop to draw 100 drops
drops[i].fall();
drops[i].show();
}

This exercise actually adds on to the previous exercise, Falling like the Rain. Instead of the lines falling down in a loop, this exercises uses two tabs in Processing to make the lines fall and float right back up. To modify this code, I made the word “priority” fall instead of lines. I chose the word priority because I was testing out possible codes that I could use in the upcoming empathy project. To make this code more interesting, I made the colour of the text random. By using the random() function, I was able to declare 10 different colours that the text could turn into. I struggled with this code as it used two tabs which I have never done before. Through trial and error and managed to make it work. Besides from random(), this exercise also uses the functions int and text() instead of line().
