Social media sites have ways to like or love different things, whether it's a post, a picture, or a status.

Whenever it's clicked, it indicates that you liked something, that it made you laugh, or that you appreciate it.

In this add-on, you'll program a Plus One button on your profile page so that users can express that they liked your page.

In this starter project, there's a Plus One My Page sprite at the bottom of the stage.

Start here.

First, create a variable.

Click on the Plus One sprite, click the Make A Variable button, and name it something that makes sense for the sprite you've created.

This example names the variable Plus One which shows up on the top corner of the stage.

Remember that a variable holds and stores a value.

For this add-on, the project will store how many people click the Plus One button and like the page.

Move the Plus One display box over to the Plus My Page sprite and double click the display box to make it appear larger on the stage just like you did in the previous videos.

Cool.

Next, code the Plus One button to increase by one every time the sprite is clicked.

Drag out the Change Plus One By One block into the Scripts Editor.

When you click on this block the variable increases by one.

If you change the value in the block to a larger number, like 10, then every time you click the block, the variable increases by 10.

This example uses one in the value.

Since the variable should increase when the sprite is clicked, add a When This Sprite Clicked event from the Events menu.

Test your code.

When the sprite is clicked, the page increase by one.

Awesome.

Finally, program the plus one count to start at zero when the flag is clicked.

Drag out a Set Plus One To Zero block into the Scripts Editor.

When you click this block, the variable count goes to zero.

To make this code run when the flag is clicked add a When Flag Clicked block to the top of the Set Plus One To block.

Great and test it out.

When the flag is clicked, the variable count resets to zero.

Then when you click on the Plus One sprite the count increases.

Now users can interact with your page and show that they liked it.

Now it's your turn.

Create a Plus One variable for the Plus One sprite.

Code the variable to change by a value when it's clicked, and reset when the flag is clicked.
