im trying to make a color changing flower screen saver for my mom as a assignment i have to do but im using ellipses and cant figure out how to make the ellipse rotate more than once in the exact same spot it was in last time can you guys help me?pls

void setup() {  
size(500,500);  
frameRate(1);  
}  
float z = 90;  
color aColor = color(random(0,255),random(0,255),random(0,255));  
color bColor = color(random(0,255),random(0,255),random(0,255));  
color cColor = color(random(0,255),random(0,255),random(0,255));  
color dColor = color(random(0,255),random(0,255),random(0,255));  
color eColor = color(random(0,255),random(0,255),random(0,255));  
color fColor = color(random(0,255),random(0,255),random(0,255));  
color gColor = color(random(0,255),random(0,255),random(0,255));  
color hColor = color(random(0,255),random(0,255),random(0,255));  
color iColor = color(random(0,255),random(0,255),random(0,255));  
color jColor = color(random(0,255),random(0,255),random(0,255));  
color kColor = color(random(0,255),random(0,255),random(0,255));  
color lColor = color(random(0,255),random(0,255),random(0,255));  
color mColor = color(random(0,255),random(0,255),random(0,255));  
color nColor = color(random(0,255),random(0,255),random(0,255));  
void draw() {  
translate(width/2,height/2);  
background(0, 200, 255);  
fill(0,180,0);  
rect(-10,20,20,100);  
fill(132,0,48);  
ellipse(0,0,50,50);  
fill(aColor);  
stroke(bColor);  
rotate(z);  
{z += 180;  
if (z \> 280);{  
z = 90;  
}  
ellipse(0,0,30,80);  
}  
}

Hi  
Welcome

Here is how to use rotate

> **[Reference](https://processing.org/reference/rotate_.html)**
>
> Rotates a shape the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO\_PI) or converted to radians with the radians() function.

Hi!  
I have a few suggestions for your code! It could make the code shorter faster and better!

@williammannisto note that using frameRate(1) making execution very slow

```auto
void setup() {
size(500,500);
frameRate(1);
}

```
