Hey Guys, how do I change the colour of the background in order? Starting from 250, ending at 0 and then looping it? Thanks for your support 🙂

> Howdy! I want to create a sequence of events as determined by an array, but for some reason, only the last element of the array is accounted for. Also, I would like the actions to occur with a slight delay with respect to each other. The delay() function would not work as it would stop all the program, while I would need the program to keep on running during the delay. Below is some code to make a particular color square according to the integer stored in an array. The only square that seems …

Thanks slow\_izzm!! Unfortunately I still don’t get it right… I updated my code and now the values from the array run in order but I still can’t see the background changing ☹

~~Your colour values are all fully transparent so try
`background(color(array[i]));`~~

Hi @anderbaer,
Your screen is refreshed only after the end of the draw() function.
So when you are doing this:
```auto
int i = 0;
int[] array = {250, 150, 100, 50, 0};
void setup() {
size(500, 500);
}
void draw() {
for (int i = 0; i < array.length; i++) {
background(array[i]);
}
}
```
You are indeed looping through all your background colors but only the last one is displayed. You can verify that by changing the last value of your array.
To loop through your background colors and see it change you need another variable that will hold the current background number and display this one.
For example, you can change the color of your background every 60 frames with the following code:
```auto
int[] array = {250, 150, 100, 50, 150};
int currentBackground;
void setup() {
size(500, 500);
currentBackground = 0;
}
void draw() {
if (frameCount % 60 == 0) {
changeBackground();
}
background(array[currentBackground]);
}
void changeBackground() {
currentBackground++;
if (currentBackground == array.length) {
currentBackground = 0;
}
}
```
