In this codelab, you'll learn how to create a launcher game and keep score.

Use the arrow keys to point the player in a specific direction, then use the space bar to launch. Get to the finish line!

What you'll learn

• Review loops.
• Practice using if/else conditional blocks.
• Practice using variables.
• Learn about cloning.

Open the starter project and click Remix.

First, we are going to get a sprite moving across the screen until it reaches the finish line.

Useful blocks:

Steps

1. Select a sprite from the sprite library to be player 1.
2. Make the sprite move continuously across the screen.
3. Have the sprite stop once it reaches the finish line.
4. Set a starting position for your sprite. Your sprite should also return here after touching the finish line.

Next, we are going to control player 1's motion.

Useful blocks:

Steps

1. Have your sprite turn as you press the left and right arrow keys.

Now, we are going to add enemies and have them spawn after each win.

Useful blocks:

Steps

1. Add another sprite as an enemy.
2. Make the enemy sprite bounce around the stage
3. Make the enemy sprite clone itself whenever player 1 reaches the finish line.
4. Have each enemy sprite clone start off pointing in a random direction.

Now, we are going to add a variable to keep track of the score.

Steps

1. Create a "score" variable for the player sprite. Write your choice for the name of your variable.
2. Use a conditional to add to the "score" variable when the player reaches the finish line.
3. Have the score reset to 0 when a person restarts the game.
