Repetitive code

[Quorum]

Good morning everyone,
I just started using processing.
I’m drawing a sketch where I’m going to create 30 little balls.
There’s a way to make them appear in sequence without writing 30 times the same line with the ellipse?

Thanks in advance

Hello,

Resources

I encourage you to review the resources available here:

• Processing website has references, examples, tutorials, etc.
  https://processing.org/
• Those available with the Processing PDE (IDE).
  An exploration of the tabs will reveal what is available; there are libraries and examples there.
• The Processing Foundation

  Check out the tabs.
  In the education tab, there is a reference to the Coding Train.

Very Nice! Thank you

you can also work with arrays (lists) and the for loop over the arrays (see tutorial)

for example first array x[], then y[] then speedX[] and speedY[]

so the properties of ONE ball is in the arrays in the same line each.(one ball properties in each array, in the same line)

• ball 0 in line 0 of all arrays, ball 1 in line 1 of all arrays

for(int i........) {
    ellipse(x[i], y[i], 7,7);
    x[i] = x[i] + speedX[i];
    y[i] = y[i] + speedY[i];
}

I’ll try it today
Thank you very much
