🔒 Extra Boxes in Rows

[north grail]

I made a small program that generates boxes based on a random number under 7. The generation works fine, but sometimes, the boxes exceed the row limit i made. could i please get some help?

@fervent drift

this good?

[fervent drift]

yep! taking a look now

[north grail]

ty

[fervent drift]

onw thing I see immediately is that you have a lot of repeat code that could be simplified, but that can wait for a moment

[north grail]

yea

i can make it just change pen colors in the if statements, and then have the square making on the bottom

[fervent drift]

yep!

[north grail]

theres an extra box

[fervent drift]

mhmm, I see what you mean

[north grail]

how do i fix that?

[fervent drift]

How indeed, interestingly it seems to happen at consistent intervals. Let's take a look at what xcor is in each loop. I'll add a print right before your final if statement there, you do the same and let's see if we can't find a pattern

ale

wierd, theres decimals

[fervent drift]

yep, that's what I see, too. As I suspected, floating point errors. I'm guessing that the turtle module is doing some weird math to adjust the size of the "distance" units to the size of the viewport, though I can't see anything about it in the docs. For now, I'd say check for xcor() > 348 or something like that and leave a comment for why it's not quite 350

alr tysm

[fervent drift]

good luck! This is a fun little program, come back and post if you do more with it!

[north grail]

Sure!

IT WORKED
