Basic white triangle grid homework pls help

Processing Coding Questions

could anyone sort me out with this
I’m trying to make a grid of upside down white triangles exactly like

[Album] imgur.com

with nested loops
but so far I’ve only gotten

[Album] imgur.com

that has misaligned non grid triangles
I’ve no idea what to change in the variables now, any help would be seriously appreciated

my current code

void setup() {
size(420, 420);
background(0, 255, 0);
noStroke();
}

void draw() {
for (int x = 0; x <= 420; x += width/6) {
for (int y = 0; y <= 420; y += height/6)

triangle(x, y, x + 70, y, x += 35, y + 70 );

}
}

thank you

Hello,

There are resources (tutorials, references, examples) here:

it is unnecessary (and evil) to add something to the x variable.

x += 35

You change the variable of the for-loop. Or was it a typo?
Don’t do this.

Example

Example which is not correct but should get you started



void setup() {
  size(420, 420);
  background(0, 255, 0);
  noStroke();
}

void draw() {
  for (int x = 0; x <= 420; x += width/6) {
    for (int y = 0; y <= 420; y += height/6) {
      triangle(x, y, 
        x - 35, y+70, 
        x+35, y+70);
    }
  }
}
