Scratch Lab 1

Payson

Period 7

Lab #1

Lab Overview

Write a script where 6 sprites start at the center of the screen. When the green flag is clicked, the sprites should use the glide command to go to a given location. When done, the sprites should form a hexagon. You might need to do some math to figure out the coordinates.

My Solution

My solution involved moving the sprite in intervals of one hundred. I put the sprite on the right at (0,200),the one below it at (100,-100), and so on. One difficulty I had with the lab was getting my hexagon to have equal distance between the sprites. I ended up having a squished hexagon but a hexagon none the less.

Lab Overview

Create your own sprite. You can use the drawing tools given in scratch. Create at least two costumes for the sprite. The sprite should change costume at least three times when the script is run. Create at least two stage backdrops using the following tools (located in bottom left corner.) Write a script that moves a sprite across a the screen and changes the background when it reaches about the middle of the screen.

My Solution

My solution involved linking the arrow keys to costume changes and background changes. This way, right arrow would make my sprite step right and the background would change. I did by choosing multiple backgrounds and setting the command to "next background" every time the arrow keys were pressed so it would cycle through.

Questions

  1. Go to the scratch home page and click explore and then animations Scratch Find an animation that you like. Click on “see inside”. What blocks do you recognize? What is unfamiliar?
    • I have used Scratch for "If, Then statments" in alegebra so most of the basic commands are recognizable.
  2. How large is the scratch screen?
    • 480 on the x-axis, 360 on the y-axis.
  3. Where is the center of the scratch screen?
    • (0,0)
  4. What are the units of measurement of the scratch screen?
    • Pixels
  5. How many sprites can you have on the screen? How many stages? Explain why this makes sense.
    • Infinite Sprites at a time but only 1 background. There cant be more than one background; not possible. However you can code multiple Sprites.
