Hi there! I want to make a loop with diagonal lines whose inclination grows little by little. My loop draws lines 10 by 10, but I want to incline them 1 by 1 and I don’t know how. If I use variable ‘i’ I think increase start from 20, but if I create another variable that grows 1 by 1 does not work. Could you please help me?
size(1000,1000);
strokeWeight(3);
for (int i =-100; i<=1100; i+=20) {
for (int j =0; j<=1000; j++) {
stroke(255,0,0);
line(i+i,0,i,1000);
}
}
Not really understand what you are trying to achieve? Something like that ?
void draw() {
background(0);
strokeWeight(1);
stroke(255,0,0);
for (int i = 0; i < 90; i++) {
pushMatrix();
translate(0,height);
rotate(radians(i));
line(0,0,0,-height);
popMatrix();
}
}
You only need ONE for loop with i
You don’t need pushMatrix or translate etc.
The line command could be
line(i, 100, i2, 60);
i2=i2+3;
sorry, I think that I did not explain this correctly. This is want I am trying to do
And?
Does my version work?
You can just do it like this … (first two lines parallel and afterwards increase w counter for increase spacing)
void draw() {
background(0);
strokeWeight(3);
stroke(255,0,0);
for (int w=0,i=10;i+w<width;i+=10) {
line(i,height,i+w,0);
if (i>10)
w++;
}
}

I think that your version changes both axis of the lines
thank you so much, I would never been able to imagine this solution
Nice solution, i always forget you can declare multiple variables in a for loop, there’s so much to remember and some things slip the memory bank lol
I have used your smart idea to make this growing loop and now I would like to make a decreasing one, as you can see on the picture, but I don’t find the way. Could you please help me?
size(1000,1000);
background(0);
strokeWeight(3);
stroke(0,0,255);
for(int w=0, i=0; i<300; i+=10+w) {
line(i,0, i,1000);
w++;
}
for(int w=0, i=300; i<600; i+=10-w) {
line(i,0, i,1000);
w++;
}
Hi
Idea without loop
int c = 1;
int move=0;
void setup() {
size(600, 600);
}
void draw() {
//background(255);
move= move + c;
line(move, width, move, 0);
c= c +1;
}
Really interesting, but I still don’t know how to make a decreasing loop with that
Hi
It’s same @mnse code
void draw() {
background(0);
strokeWeight(3);
stroke(255,0,0);
// for (int w=0,i=10;i+w<width;i++) {
for (int w=0,i=10;i+w<width;i++) {
int d =i+w;
line(d,height,d,0);
// if (i>10)
w=w+15;
}
}
I could make an increasing loop with that idea, but not a decreasing one like the one you can see on the picture
size(1000,1000);
background(0);
strokeWeight(3);
stroke(0,0,255);
for(int w=0, i=0; i<300; i+=10+w) {
line(i,0, i,1000);
w++;
}
for(int w=0, i=300; i<600; i+=10-w) {
line(i,0, i,1000);
w++;
}
Why not !?
void draw() {
background(0);
strokeWeight(1);
stroke(255,0,0);
for(int i=0,w=0; i<width; i+=10+w) {
line(i,0, i,height);
if (i < width/2)
w++;
else
w--;
}
}
or if you want it even more unreadable and compact 
void draw() {
background(0);
strokeWeight(1);
stroke(255,0,0);
for(int i=0,w=0; i<width;w+=((i < width/2) ? 1 : -1), i+=10+w) {
line(i,0, i,height);
}
}

amazing! now I am trying something more complex, make the space between lines larger and also the thickness of the lines, as you can see on the picture. I have created a new variable on the loop but I think it is not working
size(1000,1000);
background(255,255,255);
stroke(255,0,0);
for(int i=0,w=0,u=0; i<1000; i+=16+w) {
strokeWeight(8+u);
line(i,0, i,1000);
if (i < 300)
w++;
else if(i <300)
u+=8;
else if (i < 600)
w--;
else
w = 0;
}
This doesn’t work as if i < 300 it only goes into first branch where you increasing w the second branch is never reached…

thanks! And could you just tell me why these two loops do not grow tangentially?
size (1000,1000);
background(0);
strokeWeight(10);
for(int i=0,w=0; i<width; i+=20+w) {
stroke(0,0,255);
line(i+50,0, i,height);
if (i < 500)
w=w+1;
}
for(int k=10,v=0; k<width; k+=20+v) {
stroke(0,255,0);
line(k+50,0, k,height);
if (k < 500)
v=v+1;
}
I really don’t know why these lines are not together if they have same thickness and they grow with same distances between them, do you know what I should improve?
