Scratch Tutorial 3 - Looks category and Sound category blocks

Sorry if it's been a while, but hope you enjoy this new brief tutorial on Scratch.

This tutorial will cover the Looks category and Sound category blocks

In these tutorials, "default" will mean what the block looks like in the pallete (before changing block's inputs.)
Some (but not all) info was retrieved from the Scratch Wiki

Words like this will appear in the glossary at the bottom.

SO LET'S GET STARTED!!!!!!!!!!!!


Looks category blocks

These blocks will change whatever sprite looks like in some way (some can be used for the backdrop too.) Here are the blocks:

So now, let the explanations begin!


Say __ for _ seconds

  • Text to say: "Hello!"
  • Seconds to say it: 2

Say __

  • If you want to remove the speech bubble, then make one of the above blocks with the text input is blank.

Think __ for _ seconds

This block will make a thought bubble appear over the selected sprite. The defaults are:

  • String in thought bubble: "Hmm..."

The seven graphic effects in scratch

Before we go further with the blocks, I just needed to point out the seven graphic effects in Scratch. Here goes.

  • color (the overall color of the sprite\backdrop)
  • fisheye (bulge around center of sprite\backdrop)
  • whirl (vortex)
  • pixelate (rough size of pixels)
  • mosaic (copies of sprite\backdrop evenly laid out in rows and collumns)
  • brightness (the brightness of your sprite\backdrop)
  • ghost (transparency)

change __ effect by _

This will change a certain effect for your sprite\backdrop by a certain amount. The default inputs are:

  • Graphic effect: color
  • Amount: 25

set __ to __

This block will set a certain graphic effect to a certain number. The default inputs are:

  • graphic effect: color
  • amount: 0

clear graphic effects

This block has no inputs and will clear all graphical effects.


Show

This block has no inputs and will make the sprite visible.


Hide

This block has no inputs and will make the sprite invisible.


go to __ layer

This block will make the sprite go to the front or back layer. The default layer input is front.


go __ _ layers

This block will make a sprite go forward or backward a certain number of layers. The defaults are:

  • Forward or backward: forward
  • Number of layers: 1

Looks reporter blocks

These are the looks reporter blocks.

You can't use these like normal blocks (sticking them together), but I will explain their use in later tutorials.




Sound category blocks

These are the sound category blocks:

So yeah, I will start explaining the sound category blocks


Play sound __ until done

This will play a sound, and the rest of the code in the script will not run until the sound is done playing. The default sound is whatever comes first in the list of sounds.


Play sound __

This will play a sound. The default sound is whatever comes first in the list of sounds.


Stop all sounds

The name of the block says it all. All sounds will be stopped.


Sound effects

Sound effects will effect sounds. Here are the two current sound effects

  • Pitch (how high or low the pitch of a sound is)
  • Pan left/right (moving the sound closer to the beginning or end of sound)

Change __ effect by __

This block will change a certain sound effect by a certain amount. The default inputs are:

  • Effect: pitch
  • Amount: 10

Set __ effect to __

This block will st an effect to a certain amount. The default inputs are:

  • Effect: pitch
  • Amount: 100

Sound reporter block: volume

The only sound reporter block is volume. You can use it for operators and other stuff (explained in later tutorials).




AND THAT'S IT FOR NOW!!!!!!!!!




Stay tuned for the next tutorial, control and sensing blocks.

DungeonMaster00

@NDLFOREVER yeah mass reporting sucks. on repl.it, there's different problems, like spam (might be on scratch i don't know.

k9chelsea2

true and the guidlines are broken much more frequently on here, i literaly could fix mass reporting using a simple scratch project but the ST just don't want to do anything about it and do not respond to appeals -_-
