In this add-on, you'll create a second player that will be controlled with a different set of keys.

Complete this add-on only if you haven't already programmed the other two-player option.

The Player 2 sprite will have a lot of the same code as the first-player sprite you programmed.

So copy the Player 1 sprite.

Right-click the sprite, and select Duplicate.

Next, change the appearance of Player 2.

Click the Costumes tab, then Choose New Costume from Library.

Pick a costume.

To delete the other costume, click the X next to the costume.

Click the flag and the arrow keys to test.

Oh no!

Player 2 turns when the arrow keys are pressed, just like Player 1.

That's a bug.

Two players using the same keys won't work for this game.

Two-player computer games generally use the W, A, S, and D keys for the second player.

In the dropdown menu, change the left-arrow key to A and the right-arrow key to D.

Test your code.


Now the two sprites are controlled by different keys.

But they still start right on top of each other, which is a little weird.

To fix this, set the sprite starting position.

The code currently reads, when the flag is clicked, set the score to zero.

Then go to a specific spot.

The spot where the sprite starts needs to change.

This example will make Player 2 start a little lower by entering Y equals negative 60.

When the fish is hit by a shark or touches the finish line, it goes back to a specific spot.

So, change that to y equals negative 60 as well.

Now, go back and make the other player start a little higher, maybe at y equals 60.

Click the flag to test.

There's another bug.

Both players only have one score.

To give Player 2 a different score, make a new variable called player 2 score.

Make player 2 score increase when it crosses the finish line by clicking the dropdown menu next to change score and selecting player 2 score.

Start player 2 score at zero by clicking the dropdown menu on the set score to 0 block and selecting player 2 score.

Test your code.


Both players can score points.

Now it's your turn.

Add a new sprite and program the sprite to move with its own set of keys.

Set the sprite score and starting position, then ask your neighbor to play your game.
