In this codelab, you'll learn how to make an instagram-like app.

What you'll learn

• Use effects to change an image.
• Use broadcasting to communicate between sprites.
• Review conditional (if/else) blocks.
• Review variables.

Open the starter project and click Remix.

First, we are going to program the color and reset functionalities.

Steps

1. Make the color sprite broadcast a "color" message.
   
2. Make the nature sprite change colors when it receives the message.
   
   
3. Make the reset sprite broadcast a reset message.
4. Make the nature sprite clear graphic effects when it receives the reset message.
   

Next, we are going to add the rest of the effects

Steps

1. Program the ghost, pixelate, mosaic, and fisheye sprites to broadcast messages.
2. Program the nature sprite to change ghost, pixelate, mosaic, and fisheye effects when it receives those messages.
3. Add one or more other effect buttons you want.
   Examples:
       
   
       

Now, we are going to keep track of the number of changes made to the image

Steps

1. Create a new variable. Have it start with a value of zero.
   
2. Each time a button is clicked, add one to your variable.
   
3. Reset the variable to zero everytime the reset button is clicked.

Now, we are going to add the abilitiy to switch pictures

Switch between costumes

1. Add a button to switch between nature costumes when clicked.
   
2. Program the nature sprite to switch costumes when clicked.
   

Switch between image sprites

1. Program the category buttons to switch between image sprites.
   
   
   
2. Add code to the "people" and "things" sprites to change their graphic effects.
   Tip: Drag the code from the nature sprite to the people or things sprite.
