Question: Draw a character that would fit within a 40×40 pixel box. Once you have this working, use for loops to “tile” the image 100 times on a 400×400 pixel canvas. Hint: can you do this using only 2 for loops?
problem: every time I attempt this program it always fails and I cant make it only with 2 loops, can anyone help me start off the code? It wont let me write my code.

Hi
Post your attempt

Its working now, I can type my code here it is.
```auto
function setup() {
createCanvas(400, 400);
}
function draw() {
background(220);
for (var x= 0; x <= width; x += 40) {
for (var y= 0; y <= height; y += 40) {
fill(255,0,255);
ellipse(x, y, 25, 25)
}
}
}
```
I put the for loops together as I cant figure out how to make it so that I only have two loops but have the same out come.
How do I make it so that it tiles it 100 times.

Hi
Change this values x += 40
Y+= 40… let’s say make it 10
See what happens
Then change this values
ellipse(x, y, 25, 25) and see what happens
Edit
for (var x= 0; x \<= width; x += 40) {
for (var y= 0; y \<= height; y += 40)
For var x =0; and var y=0; change zero with other values see what happens

Thank so much! I changed your solution a bit so I could fit the question but I got it 🙂
