hello!
i’m trying to rewrite this code in processing:
[https://www.openprocessing.org/sketch/617540](https://www.openprocessing.org/sketch/617540)
but there is a part i don’t understand
row 8:
`noiseSeed = noiseSeed || 1`
this code pass to block function an int:
```auto
for(var i=0;i<3;i++){
push()
translate(width/2 - (i-1)*(height-60),height/2)
Block(i)
pop()
}
```
but if i try to do the same in processing i con’t…how i have to convert this operation?
thank you for the answer!

```auto
noiseSeed = noiseSeed || 1
```
The `noiseSeed` will be 1 if previous `noiseSeed` is 0.
So that line preventing `noiseSeed` become 0.
the `||` symbol means `or` operation. it behaves different to each data type. for example
let `stringA` is a string
`stringA = stringA || "ABCD"`
if `stringA` is empty it will returns “ABCD” otherwise no changes.
for object, it will check if it `null` or not
in processing, you can change that line to
`noiseSeed = noiseSeed == 0 ? 1 : noiseSeed;`

really thank you!
but the code still doesn’t work
```auto
float counter = 1;
void setup() {
size(1920, 1080, P2D);
background(0);
}
void draw() {
background(0);
for (int i=0; i<3; i++) {
pushMatrix();
translate(width/2 - (i-1)*(height-60), height/2);
Block(i);
popMatrix();
}
pushMatrix();
stroke(255);
strokeWeight(2);
line(0, 10, width, 10);
line(0, height-10, width, height-10);
popMatrix();
}
void Block(int noiseSeed) {
noiseSeed = noiseSeed == 0 ? 1 : noiseSeed;
if (frameCount>100) {
counter = lerp(counter, 200, 0.1);
}
int selected = int(noise(frameCount/400, noiseSeed)*100);
for (int i=0; i<100; i++) {
pushMatrix();
float ang = noise(frameCount/500, i, noiseSeed*100)* 3 * PI + noiseSeed*10;
float r = counter;
PVector p =new PVector(1, 1).mult(r).rotate(ang);
fill(255);
if (i==selected) {
fill(255, 0, 0);
}
stroke(255, 70);
line(0, 0, p.x, p.y);
noStroke();
rect(p.x, p.y, 5, 5);
if (i==selected) {
pushMatrix();
translate(p.x, p.y);
rect(20, 0, 40, 3);
rect(20, 10, 15, 3);
rect(20, 20, 65, 3);
text("POZ: "+ int(p.x)+ ", " + int(p.y) + "<"+ang, 20, 50);
popMatrix();
}
popMatrix();
}
stroke(255);
noFill();
ellipse(0, 0, 50, 50);
textSize(10);
text("TARGET #ID: "+selected, 20, 20);
if (frameCount % 200 <30) {
if (frameCount % 4<2) {
background(255);
} else {
// background(0)
}
}
int edge = height - 100;
stroke(255) ;
rect(-edge/2, -edge/2, edge, edge);
edge = height - 80;
stroke(255, 30);
rect(-edge/2, -edge/2, edge, edge);
noStroke();
fill(255);
textSize(12);
text("EXPR#"+noiseSeed, -edge/2, -edge/2+ 10);
}
```
what’s wrong?

frameCount is an integer. try to cast it to float first on line 32 and 27

In order to avoid an integer division in Java, at least 1 of the operands gotta be a floating value: `frameCount/400.0`
