So I've played around with some of the stuff for awhile, and I've created two functions. One that makes a single quadrant of the first problem, and one that creates a single wiggly line for the second problem. This is just a base for you to work of in this process. Here's each of the functions. Also, note that each of them takes in the turtle as a parameter:
function makeLineQuadrant(turtle) {
// this currently makes the top left corner:
let yVal = windowWidth * 0.5;
let xVal = windowWidth * 0.5;
for (let i = 0; i < 13; i++) {
// loop through the 12 lines in one quadrant
turtle.face(0); // reset for the new round
turtle.penUp();
let startLeft = i * ((windowWidth * 0.5) / 12); // decide which component on the button we should start at
let endTop = (12 - i) * ((windowWidth * 0.5) / 12); // how far down the y-axis should we go? You should write this out on paper to see how it works
turtle.goto(startLeft, yVal);
turtle.penDown();
let deg = turtle.angleTo(xVal, endTop); // what direction do I need to turn?
turtle.face(deg);
let distance = turtle.distanceTo(xVal, endTop); // how far away is it?
turtle.forward(distance);
}
}
I tried to add a few comments throughout, but if there is any step that is confusing, please add a comment.
function makeSquiggle(turtle) {
turtle.setColor(color(random(0, 255), random(0, 255), random(0, 255)));
let middleX = windowWidth * 0.5, middleY = windowHeight * 0.5;
turtle.goto(windowWidth * 0.5, windowHeight * 0.5);
// let's start moving in a random direction UNTIL our distance from the center is greater than some number X
let X = 300; // arbitrary distance from center
// some variables that can help us get some random movement for our turtle:
let turtleXvel = random(-3, 3), turtleYvel = random(-3, 3);
while (turtle.distanceTo(middleX, middleY) < X) {
turtle.face(0);
// calculate movement:
let newXmove = turtle.x + turtleXvel, newYmove = turtle.y + turtleYvel;
// direct our turtle:
turtle.face(turtle.angleTo(newXmove, newYmove));
let distance = turtle.distanceTo(newXmove, newYmove); // how far away is it?
// move our turtle
turtle.penDown();
turtle.forward(distance);
// change the velocity a little bit for a smooth curving:
turtleXvel += random(-1, 1);
turtleYvel += random(-1, 1);
}
}
Note that I'm changing the velocities instead of the position directly. This is a classic Calculus / Physics problem where the derivative gives us a smaller range, so adjusting turtleXvel and turtleYvel change the position in much less drastic ways versus:
turtle.x += random(-1, 1);
turtle.y += random(-1, 1);
You should look at the difference as well to visualize this. Beyond this is working with these structural components to finish this up!
