Activity 2: Making the Face Filters Clickable

Objective

Now we want the main filter to change when we click the filters at the bottom.

Lets Code

1. Open PictoBlox and open Face Filter saved sb3 file and continue from there.
2. Select Face Filter 2.
3. To trigger a change in the filter we will broadcast a message when a sprite is clicked. Thus, drag and drop when this sprite is clicked block, place broadcast message block, and set the new message as heart goggles. Do this for all 4 sprites. Add different messages to each sprite.
4. Now let’s select the main Face filter sprite and make a script to change the costume when it receives the broadcasted message. Place a when I receive broadcast block from the Controls Palette and switch the message to heart goggles.
5. Drag and drop the switch costume to block and select Heart Goggles from the drop-down.
6. Right-click on this script and duplicate the number of times we have the face filters times and change it for each and every filter by selecting their broadcast message and costume from the drop-down.

Now your basic script is ready.

Save the file.

Click on the flag button and test your filters.
