ok if i got you right you want the function to return a value — in your case the height of the legs. this value could then be used in a while loop. while loops are quite helpful but might run forever if done incorrect. I adapted the code a bit so the legs function returns the length of the legs which is then added to the y value in the while loop. There is a check inside the while loop so it will run for a maximum of 3000 times.
# -------------
# settings
pw = ph = 500
amount_x = 10
cell_w = pw / amount_x
max_h = 50
gap = max_h * .2
# -------------
# fucntion(s)
def legs(pos, max_w, max_h):
x, y = pos
length = random() * max_h
step_s = random() * max_w
polygon((x - step_s, y) , (x, y + length), (x + step_s, y), close = False)
return length
# -------------
# drawings
newPage(pw, ph)
fill(None)
stroke(0)
strokeWidth(2)
for x in range(amount_x):
count = 0
y = -random() * max_h
while y < ph:
y += legs((x * cell_w + cell_w/2, y), cell_w/2, max_h)
y += gap
count += 1
if count > 3000: break
and the while loop without the check:
for x in range(amount_x):
y = -random() * max_h
while y < ph:
y += legs((x * cell_w + cell_w/2, y), cell_w/2, max_h)
y += gap
