Yes, one of my students from last semester coded me a valentine. And then is making me debug it
What he is trying to do is get his buzzbot to spiral. Starting in the center and spiraling out, then spiraling back in. We ended up settling on a different method, the one you see, so I’m not sure if I’d call it “expected.” We tried having the rotation value to change at the same rate and the x and y, but it was…a bit erratic.
Any suggestions on how to make a sprite spiral?
This is a tough one. I would be inclined to suggest my own students to look into the old Frozen Hour of Code activities to see about the angles and the repetition needed to make a sprite spiral. Just a thought. What other ideas are out there?
Not sure this is exactly what you are looking for but you might try sprite.rotateToDirection? If you add:
flyBot.rotateToDirection=true;
flyBot.rotation=flyBot.rotation+5
You should see the flyBot walk in a circle (if you take away the other movement). To make that circle spiral in and out, you probably need to experiment with a while loop that would change the number you use to increase/decrease the rotation each time through the loop. Just an idea .
