Hello @rustyrobison,
This can be confirmed by changing the loop count; I tried a few lower values and it did not give an error message.
The code provided is fading in a for() loop and this will be rapid and not be seen over time.
Consider fading over time in the draw() loop which is 60 fps:
if (fading)
{
f++;
if (f>255)
{
f = 0;
fading = false;
}
textSize(48);
text(f, width/2, height/2)
}
Above code is not complete but worked when used to fade an image over time with tint().
:)
