Try Valentine's Balloon Dash for fun Scratch Project!
Valentine's Balloon Dash
Platform: Scratch
Level: intermediate
In this project, students will develop a game where different colored heart-shaped balloons float across the screen while the puppy character tries to catch them. Each time a balloon is caught, the score increases, but if a balloon disappears, the score decreases. The project will involve cloning balloons at random positions, using variables to track points, and implementing sensing to determine if the puppy catches a balloon. Messaging can be used to signal when a balloon is created or disappears.

Valentine's Balloon Dash: Solution Outline
These are the high level steps to create this project. Try to create the project on your own first as much as possible, before checking the detailed solution samples below.
- Create the puppy character and set up its movement.
- Create the heart-shaped balloon and set up cloning.
- Implement scoring system with variables.
- Use messaging to manage balloon creation and disappearance.
Valentine's Balloon Dash Sample Solutions
This section provides detailed, step-by-step instructions on how to build the project. There are many ways to create a project, so feel free to explore different approaches. Please note that these instructions are Al-generated, so errors may occur and the coding blocks may not map to Scratch exactly. But it should serve as very valuable references. Stay attentive as you follow along, and enjoy!
First, add the puppy sprite to your Scratch project. Use the arrow keys to control the puppy's movement. You can use the 'when key pressed' blocks to move the puppy up, down, left, and right. This will allow the puppy to move around the screen to catch the balloons.
Add a heart-shaped balloon sprite to your project. Use the 'when I start as a clone' block to make the balloons appear at random positions at the top of the screen and float downwards. Use the 'create clone of' block to continuously generate new balloons.
Create a variable called 'Score' to keep track of the player's points. Increase the score by 1 when the puppy touches a balloon, and decrease it by 1 if a balloon reaches the bottom of the screen without being caught.
Use broadcast messages to signal when a balloon is created and when it disappears. This can help manage the game flow and provide feedback to the player, such as playing a sound or changing the background color when a balloon is missed.
Common Potential Issues in Valentine's Balloon Dash Project
It is common to have bugs in the code. Here are some of issues you might run into.
- Ensuring the puppy's movement is smooth and responsive to key presses, which might require adjusting the step size or delay between movements.
- Managing the timing of balloon creation to ensure the game is challenging but not overwhelming, which involves adjusting the wait time between creating clones.
- Handling the balloon clones properly to avoid memory issues, such as ensuring clones are deleted when they move off-screen or are caught.
Extra Challenges For Valentine's Balloon Dash
- Add different types of balloons with varying point values. For example, red balloons could be worth more points than blue ones.
- Introduce a timer to the game, where the player has to score as many points as possible within a set time limit.
