People wonder, "How big is leave a trail 3000, anyways? And why does it cover the screen no matter what?!?" Well, this is why.
When you leave a trail, let's say you put in 50 as the width.
I will change my move forward to 1 so I will show you a dot.
Now, what the width is actually saying is "Use the color ___ and fill in the amount of pixels around the character as the width." You probably don't understand this because I'm bad at explaining, but here's a better explanation:
So, when you do leave a trail 3000, it's make a circle 3000 pixels around the character, then filling it in. Your IPad would need to be HUGE for the dot to still show up as a dot.
Ask more questions about the Leave A Trail block and I will answer as soon as I can. Please tell me if you'd like to help answering questions. Please don't answer unless if I said you could, because then this won't go crazy about answering the same question a zillion times from so many people answering.
