Hello everyone,
this is my code for rain, however I would like to add splashes and an angle at which the rain comes from and I am not to sure how, I am a total noob with this. If someone can please fill in the code so that it does!! I would greatly appreciate it!
 

1. void setup () {
2.   size (600, 600);
3.   background (0);
4.   noStroke();
5. }
6. 
   
7. void draw () {
8.   fill (0, 20);
9.   rect (0, 0, height, width);
10.   fill (28, 151, 255);
11.   ellipse (random(height), random(width), 2, 15);
12. }
