Junkbots - Scoring

 Activity 7 - Scoring and breaking the rocks

This will be the main aim of the game. The code below will allow the user to touch the rock, it then breaks then disappears and a new rock spawns. 

The first task is to start a scoring system. This will show the user their score and will update the score every time they hit the rock. It will also end the game when the user reaches a score of 20, you can make this score limit any score you want.

To keep score we’ll be creating our own variable. (a data holder). On the scratch blocks scroll down on the left onto the Variables block. Create a variable named score and tick the box, like below: 

Our whole code for this part of the game will be in one big loop. The loop will repeat as long as our Score variable is less than our score limit, in this example it’s 20. To make this loop use the Control, Operators and Variable blocks together. 

The next loop will run when the user touches the rock. When this is ran, the rock will break, the score will change and a new rock will spawn. Lets break it down step by step:

  1. User touches the rock

  2. Rock changes into a new costume “broken rocks”

  3. A “crunch sound is played then stopped”

  4. Score goes up by 1

  5. Rock is hidden then dissappeares

  6. Changes costume to “rock”, not broken

  7. Goes to random position

  8. Rock is then shown again

  9. If score is less than 20, game carries on, if not game ends by hiding rock.



Now that we have a main game loop, lets make sure the scores reset whenever the game is ran. This is extremely simple and only needs two blocks:

Your task:

  • Create a variable which holds the players score

  • Create a loop which runs while the players score is less than 20

  • Create another loop which checks if the player touches the rock, in this loop you should

    • Hide the rock when it’s touched

    • Change the score

    • Spawn a new rock in a new place

  • End the game when your score limit is reached

  • Reset the score every time a new game start

Junkbots - Conclusion

Activity 8 - Extensions You’ve now successfully created your Scratch game, well done! Give the game to your partner and see what they think of it, play theirs and compare the two games. There’s still a lot more to do, below are some extra tasks you can do, or make your own up. Have fun ! Extension Tasks: Change the game so that instead of a score limit, there’s a time limit. How would you do this? What blocks would you use? Instead of there only being one item to break, add more in, each being worth a different score Add an end game screen, which shows the users score and maybe even a high score Create more than one bot, each with a different move speed, and let the user choose which one to play with Add an obstacle course, which deducts points if the user touches it.

Junkbots - Spawning some rocks

Image
  Activity 6 - Spawning rocks In this part we’ll start to spawn some rocks. When the green flag is pressed, our code will run. Try to guess what it does . Make sure you click on the “Rock” sprite before coding this part, as the code here will belong to the rock. In this example, the rock is invisible to the user at first, it then goes to a random position . If the rock is touching the edge of the screen it goes to another position, this bit is in a loop. It then becomes visible to the user. All of this happens instantly, so the user won’t be waiting for the game to start. Your task: Spawn a rock onto the screen, in a random position Make sure the rock is not off the screen Try change the code so that the rocks spawn in a place you want.

Junkbots - Introduction

What are Junkbots & intro to Scratch Junkbots is a project which has been running for many years. It aims to bring sustainability, computing and robotics together. In these activities you'll be creating the robot, which you can control on the screen, and create games with.  In these examples, we'll be using Scratch. Scratch is a type of a visual programming language that can allow you to create your own interactive stories, games or even animations, the possibilities are endless. It sounds simple, but you can easily change it up to make it do whatever you like.
