Objectives
•
learn how to use another new starting block:( the Start on Bump block).
In this game, the dog’s script will start when it is tagged by the cat. Then the dog will tag the cat, and they’ll continue to play tag until you stop the program.
Start on bump
The Start on Bump block starts a character’s script when the character bumps into another character.
Step 1
Select the farm background and add the dog. Position the cat and the dog on the stage so that they are standing about five steps a part.
The cat will move toward the dog and say “Tag ! ” Then it will move back and pause for 2 seconds to wait for the dog to tag it.
Add a Repeat Forever block to the cat’s script so the cat and the dog will play again and again.
Step 2
Create the following script for the cat
Step 3
The dog’s script uses the Start on Bump block so that it starts when the dog is bumped by the cat.
After the dog is bumped, it will wait 2 seconds to give the
cat a chance to run away. Then the dog will move to the cat,
say “Tag!” and run away.
Step 4
Create the following script for the dog
We don’t need the Repeat Forever block for the dog, because the Start on Bump block will run every time the dog is tagged.
Step 5
Tap the Green Flag button to watch your characters play tag ! Press the Stop button when you want the game to end.
Hints If a character is touching another character that has a Start on Bump script, the script will keep running until the characters are not touching anymore. For example, if you move the cat so
close to the dog that they are touching, the dog’s Start on Bump script will begin running, and it will continue to run over and over again until you move the cat away from the dog.
close to the dog that they are touching, the dog’s Start on Bump script will begin running, and it will continue to run over and over again until you move the cat away from the dog.
Challenge
Add a ball to your project and make it move all around the stage with a few different Start on Green Flag scripts that repeat forever.
Change the scripts of the cat and the dog so that when they are hit by the ball, they say “I’m out!” and then disappear. Add more characters to make the game more exciting!
