Hello again!
fill(255, 255, 0, 128); //yellow and opacity 128
noStroke();
sphere(3); // raio das bolota
At the end of function draw():
function draw() {
//background(0);
// Your code...
fill(0, 10); //black and opacity 10
rectMode(CENTER);
rect(0, 0, width, height);
}
Always fill() before the shape!
My background was black so that is why I chose black… you may have to change things on your end.
Experiment a little… I was just playing around with this and was done very quickly.
You can always go back and edit your code… as a new user you may have some limitations and have to wait a day.
This will be off the screen:
rect(windoWidth, windowHeight, windoWidth, windowHeight);
I suggest you visit the p5.js web page for tutorials, examples and references and it also has an editor:
In the p5.js editor on web page I added this to function setup() so it was initially black:
background(0);
I was using the Processing p5 mode editor initially.
This was in the p5.js editor with my suggested code changes:
