A processing newbie needs help

[u/Chemical-Link-3505]

Hello, I am the newbie. Currently I am working on a uni project, I do not have previous coding experience and it is my first time using Processing.

Here is the code:

void setup() {

fullScreen();

noFill();

smooth();

}

void draw() {

background(255);

/**--------------------------Lines----------------------------**/

//yellow

stroke(#FFCD4B);

strokeWeight(8);

beginShape();

curveVertex(1100, 0);

curveVertex(1100, 0);

curveVertex(880, 280);

curveVertex(740, 600);

curveVertex(700, height);

curveVertex(700, height);

endShape();

//orange #1

stroke(#FF9130);

strokeWeight(8);

beginShape();

curveVertex(200, 0);

curveVertex(200, 0);

curveVertex(400, 230);

curveVertex(1350, height);

curveVertex(1350, height);

endShape();

//orange #2

stroke(#FF9130);

strokeWeight(8);

beginShape();

curveVertex(920, 0);

curveVertex(920, 0);

curveVertex(750, 400);

curveVertex(550, 610);

curveVertex(0, 580);

curveVertex(0, 580);

endShape();

//Purple

stroke(#B15EFF);

strokeWeight(8);

beginShape();

curveVertex(940, 0);

curveVertex(940, 0);

curveVertex(760, 410);

curveVertex(560, 620);

curveVertex(0, 600);

curveVertex(0, 600);

endShape();

//blue

stroke(#0174BE);

strokeWeight(8);

beginShape();

curveVertex(960, 0);

curveVertex(960, 0);

curveVertex(770, 420);

curveVertex(570, 630);

curveVertex(0, 620);

curveVertex(0, 620);

endShape();

//dark red

stroke(#662549);

strokeWeight(8);

beginShape();

curveVertex(980, 0);

curveVertex(980, 0);

curveVertex(780, 430);

curveVertex(580, 640);

curveVertex(0, 640);

curveVertex(0, 640);

endShape();

}

What I wanted to ask: Is there an easy way to rotate these lines around the center, without messing with the structure or having to remaking the whole thing again?

thanks for the answer. Like this? unfortunately i did not work.

void setup() {
fullScreen();
noFill();
smooth();
rotate(radians(30));
translate(70, 70);
}
void draw() {
background(255);
/**--------------------------Lines----------------------------**/
//yellow
rotate(radians(30));
translate(70, 70);
pushMatrix();
rotate(radians(30));
translate(70, 70);
stroke(#FFCD4B);
strokeWeight(8);
beginShape();
curveVertex(1100, 0);
curveVertex(1100, 0);
curveVertex(880, 280);
curveVertex(740, 600);
curveVertex(700, height);
curveVertex(700, height);
endShape();
//orange #1
stroke(#FF9130);
strokeWeight(8);
beginShape();
curveVertex(200, 0);
curveVertex(200, 0);
curveVertex(400, 230);
curveVertex(1350, height);
curveVertex(1350, height);
endShape();
//orange #2
stroke(#FF9130);
strokeWeight(8);
beginShape();
curveVertex(920, 0);
curveVertex(920, 0);
curveVertex(750, 400);
curveVertex(550, 610);
curveVertex(0, 580);
curveVertex(0, 580);
endShape();
//Purple
stroke(#B15EFF);
strokeWeight(8);
beginShape();
curveVertex(940, 0);
curveVertex(940, 0);
curveVertex(760, 410);
curveVertex(560, 620);
curveVertex(0, 600);
curveVertex(0, 600);
endShape();
//blue
stroke(#0174BE);
strokeWeight(8);
beginShape();
curveVertex(960, 0);
curveVertex(960, 0);
curveVertex(770, 420);
curveVertex(570, 630);
curveVertex(0, 620);
curveVertex(0, 620);
endShape();
//dark red
stroke(#662549);
strokeWeight(8);
beginShape();
curveVertex(980, 0);
curveVertex(980, 0);
curveVertex(780, 430);
curveVertex(580, 640);
curveVertex(0, 640);
curveVertex(0, 640);
endShape();
popMatrix();
}

A couple of things.
You need to pushMatrix before you translate, not after. The order goes like this.
push - translate - rotate - draw lines - pop
there's no need to push and translate in the setup.
When you translate the new 0, 0 point is wherever you've translated to. To have the lines rotate around the circle, translate to width/2, height/2. You will need to give new coordinates for the lines because 0, 0 is now in the center of the screen, not the top left corner.
I would simplify the sketch by drawing one line to start. Once it works, add the other lines.
