Help needed with Random background Images

Programming Questions

Hi, I'm hours new to Processing.
I was wondering if I could have some support.

I'm trying to create a button that makes the background image change randomly.

For some reason I'm finding this incredibly hard.

String[] words = { "i1.png", "i2.png", "i3.png", "i4.png", "i5.png", "i6.png", "i7.png" };

int index = int(random(words.length)); // same as int(random(NUMBER))

(words[index]);

This is the pile of junk I have so far.

The code you've posted can be reduced to this single line:

String filename = "i" + ((int) random(1,8)) + ".png";

If your images are consistently named, as in your example, then you don't need the array.

If your images are inconsistently named, making the array necessary. then a shorter version would be:

String filename = words[ (int) random(words.length()) ];

At this point you still need to *use* the filename.... But I'm not sure if that's what you need help with...
